This is one of the sql questions that is very commonly asked. I have a web page with a textbox. When I enter a table name in the textbox and when I click "Load Data" button, we want to retrieve data from that respective table and display it on the page. Copy the SQL Script to create the tables from my blog using the link below http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html Create the following stored procedure. Notice we are passing table name as a parameter to the stored prcoedure. In the body of the stored procedure we are concatenating strings to build our dynamic sql statement. In our previous videos we discussed that this open doors for SQL injection. Create procedure spDynamicTableName @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from ' + @TableName Execute sp_executesql @sql End So the obvious question that comes to our mind is, why are we not creating parameterised sql statement instead. The answers is we can't. SQL Server does not allow table names and column names to be passed as parameters. Notice in the example below, we are creating a parameterised query with @TabName as a parameter. When we execute the following code, the procedure gets created successfully. Create procedure spDynamicTableName1 @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from @TabName' Execute sp_executesql @sql, N'@TabName nvarchar(100)', @TabName = @TableName End But when we try to execute it we get an error - Must declare the table variable "@TabName" Execute spDynamicTableName1 N'Countries' Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicTableName.aspx". Copy and paste the HTML from my blog using the link below http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html Copy and paste the code from my blog in the code-behind page http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html At this point, run the application and type the following text in the "Table Name" textbox and click "Load Data" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. Employees; Drop database SalesDB One way to prevent SQL injection in this case is by using SQL Server built-in function - QUOTENAME(). We will discuss QUOTENAME() function in detail in our next video. For now understand that by default, this function wraps that string that is passed to it in a pair of brackets. SELECT QUOTENAME('Employees') returns [Employees] Modify the stored procedure to use QUOTENAME() function as shown below. Alter procedure spDynamicTableName @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from ' + QUOTENAME(@TableName) Execute sp_executesql @sql End At this point, type the following text in the "Table Name" textbox and click "Load Data" button. Notice you will see a message - Invalid object name 'Employees; Drop database SalesDB'. Also "SalesDB" database is not dropped. Employees; Drop database SalesDB The entire text in "Table Name" textbox is wrapped in a pair of brackets by the QUOTENAME function and is treated as table name. Since we do have a table with the specified name, we get the error - Invalid object name.

how to use sql variable in oracle  || oracle sql tutorial 13
 
08:29
in this video i will show you how to use variable in oracle sql plus for more detail join our facebook group ,https://www.facebook.com/groups/242999206136244/ The basics: & and && Just about everyone has defined a variable in SQL*Plus using &. The basics: & and && indicate substitution variables in SQL*Plus scripts or commands. &variablename is used to refer to the variable variablename in SQL*Plus, much the same way $variablename is used in shell scripts. If variablename is undefined, then SQL*Plus prompts the user for a value. Everything from the & to the following space is considered the variable name. For example, in select &foo from dual;, &foo refers to the variable foo. If you run the LIST_INDEXES script again, you won’t be prompted for a table name at all. Instead, the value entered earlier will be reused, and you will again see information about the project_hours table and its indexes. The reason for this is that once you define a variable, that definition sticks around until you either exit SQL*Plus or explicitly undefine the variable. .----------------------------------------------------------------------------------------------------------. video courses- list of playlist : tips and trics link► https://www.youtube.com/playlist?list=PLOfLYVXrwqXrI5jvwUEi6N13QR4xCj2k2 command prompt commands: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXobXGUdGk6JhzyQ216dNiQL oracle sql: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXqoUWCoh4cARGDW13SofDO- c programming: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXrZ_Ub8EXeLY7YP1YxhoJzf .-----------------------------------------------------------------------------------------------------------. watch more videos: learn oracle sql online overview tutorail : https://www.youtube.com/watch?v=Dfesgj4w8QA&t=8s how to fix or repair a corrupted usb flash drive or cd card using command prompt: https://www.youtube.com/edit?video_id... how to copy a folder using cmd: https://www.youtube.com/watch?v=Lblhb... how to move a folder using cmd: https://www.youtube.com/watch?v=YFfHZ... how to dell files in cmd: https://www.youtube.com/watch?v=3-lqg... how to make and remove directory: https://www.youtube.com/edit?video_id... how to change color and title in cmd: https://www.youtube.com/edit?video_id... how to change directory in command prompt: https://www.youtube.com/watch?v=SmLYx... .-----------------------------------------------------------------------------------------------------------. social media links: join our group: ► https://www.facebook.com/groups/24299... ► Follow on Google+: http://[email protected] ► Follow on Twitter: https://twitter.com/@rananavi4766669 :

View & manage your progress/pace 3. In-class projects and code reviews 4. Personal guidance from your Mentors ---------------------------------------------------------------------------------------- A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory and the set of operations that can be applied to the variable. The name of a PL/SQL variable consists of a letter optionally followed by more letters, numerals, dollar signs, underscores, and number signs and should not exceed 30 characters. By default, variable names are not case-sensitive. You cannot use a reserved PL/SQL keyword as a variable name. PL/SQL programming language allows to define various types of variables, which we will cover in subsequent chapters like date time data types, records, collections, etc. For this chapter, let us study only basic variable types. With PL/SQL you can declare variables and then use them in SQL and procedural statements anywhere that an expression can be used. Variables can be used for the following: • Temporary storage of data: Data can be temporarily stored in one or more variables for use when validating data input and for processing later in the data flow process. • Manipulation of stored values: Variables can be used for calculations and other data manipulations without accessing the database. • Reusability: After they are declared, variables can be used repeatedly in an application simply by referencing them in other statements, including other declarative statements. • Ease of maintenance: When using %TYPE and %ROWTYPE (more information on %ROWTYPE is covered in a subsequent lesson), you declare variables, basing the declarations on the definitions of database columns. If an underlying definition changes, the variable declaration changes accordingly at run time. This provides data independence, reduces maintenance costs, and allows programs to adapt as the database changes to meet new business needs. More information on %TYPE is covered later in this lesson. Types of Variables" All PL/SQL variables have a data type, which specifies a storage format, constraints, and valid range of values. PL/SQL supports four data type categories—scalar, composite, reference, and LOB (large object)—that you can use for declaring variables, constants, and pointers. • Scalar data types hold a single value. The main data types are those that correspond to column types in Oracle server tables; PL/SQL also supports Boolean variables. • Composite data types, such as records, allow groups of fields to be defined and manipulated in PL/SQL blocks. • Reference data types hold values, called pointers, that designate other program items. Reference data types are not covered in this course. • LOB data types hold values, called locators, that specify the location of large objects (such as graphic images) that are stored out of line. LOB data types are discussed in detail later in this course.

SQLPLUS: LineSize & PageSize
 
03:49
In this tutorial, you'll learn how to set linesize and pagesize . PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Table valued parameters in SQL Server
 
06:46
table valued parameters example send table variable to stored procedure pass table variable as parameter to stored procedure pass table variable to sql stored procedure In this video we will discuss table valued parameters in SQL Server. Table Valued Parameter is a new feature introduced in SQL SERVER 2008. Table Valued Parameter allows a table (i.e multiple rows of data) to be passed as a parameter to a stored procedure from T-SQL code or from an application. Prior to SQL SERVER 2008, it is not possible to pass a table variable as a parameter to a stored procedure. Let us understand how to pass multiple rows to a stored procedure using Table Valued Parameter with an example. We want to insert multiple rows into the following Employees table. SQL Script to create the Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10) ) Go Step 1 : Create User-defined Table Type CREATE TYPE EmpTableType AS TABLE ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) Go Step 2 : Use the User-defined Table Type as a parameter in the stored procedure. Table valued parameters must be passed as read-only to stored procedures, functions etc. This means you cannot perform DML operations like INSERT, UPDATE or DELETE on a table-valued parameter in the body of a function, stored procedure etc. CREATE PROCEDURE spInsertEmployees @EmpTableType EmpTableType READONLY AS BEGIN INSERT INTO Employees SELECT * FROM @EmpTableType END Step 3 : Declare a table variable, insert the data and then pass the table variable as a parameter to the stored procedure. DECLARE @EmployeeTableType EmpTableType INSERT INTO @EmployeeTableType VALUES (1, 'Mark', 'Male') INSERT INTO @EmployeeTableType VALUES (2, 'Mary', 'Female') INSERT INTO @EmployeeTableType VALUES (3, 'John', 'Male') INSERT INTO @EmployeeTableType VALUES (4, 'Sara', 'Female') INSERT INTO @EmployeeTableType VALUES (5, 'Rob', 'Male') EXECUTE spInsertEmployees @EmployeeTableType That's it. Now select the data from Employees table and notice that all the rows of the table variable are inserted into the Employees table. In our next video, we will discuss how to pass table as a parameter to the stored procedure from an ADO.NET application Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/table-valued-parameters-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/table-valued-parameters-in-sql-server_17.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Oracle tutorial : Bind variables in PL SQL oracle tutorial for beginners This Oracle tutorial video will show you how to use bind variables in SQL. You can improve SQL query performance by Using Bind Variables. Bind variables Improved Security of SQL queries. Bind variables matter for performance. Before running SQL statement oracle checks that it is valid or not. and analyse how to access the tables. If a plan already exists for a query in that case Oracle not need to go through the optimization process again. so the oracle reuse the existing plan. It increase the performance.

SQL script to insert into many to many table

This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'

BASH scripting lesson 10 working with CSV files
 
12:03
More videos like this online at http://www.theurbanpenguin.com We now have some more great fun and see how much we can use the shell for; creating reports easily from the command line against CSV files. The script should be quite easy to read now as we use a while loop to read in the CSV file. We change the file delimiter to be the comma and then we have the line that we read in broken up into the schema elements we need. A report then is easy with colours and search ability. This is very usable

Dynamic SQL in SQL Server

What is Dynamic SQL 2. Simple example of using Dynamic SQL What is Dynamic SQL Dynamic SQL is a SQL built from strings at runtime. Simple example of using Dynamic SQL Here is the SQL Script to create Employees table and populate it with data Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) Go Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) Go One way to achieve this is by implementing a stored procedure as shown below that this page would call. Create Procedure spSearchEmployees @FirstName nvarchar(100), @LastName nvarchar(100), @Gender nvarchar(50), @Salary int As Begin Select * from Employees where (FirstName = @FirstName OR @FirstName IS NULL) AND (LastName = @LastName OR @LastName IS NULL) AND (Gender = @Gender OR @Gender IS NULL) AND (Salary = @Salary OR @Salary IS NULL) End Go The stored procedure in this case is not very complicated as we have only 4 search filters. What if there are 20 or more such filters. This stored procedure can get complex. To make things worse what if we want to specify conditions like AND, OR etc between these search filters. The stored procedure can get extremely large, complicated and difficult to maintain. One way to reduce the complexity is by using dynamic SQL as show below. Depending on for which search filters the user has provided the values on the "Search Page", we build the WHERE clause dynamically at runtime, which can reduce complexity. However, you might hear arguments that dynamic sql is bad both in-terms of security and performance. This is true if the dynamic sql is not properly implemented. From a security standpoint, it may open doors for SQL injection attack and from a performance standpoint, the cached query plans may not be reused. If properly implemented, we will not have these problems with dynamic sql. In our upcoming videos, we will discuss good and bad dynamic sql implementations. For now let's implement a simple example that makes use of dynamic sql. In the example below we are assuming the user has supplied values only for FirstName and LastName search fields. To execute the dynamicl sql we are using system stored procedure sp_executesql. sp_executesql takes two pre-defined parameters and any number of user-defined parameters. @statement - The is the first parameter which is mandatory, and contains the SQL statements to execute @params - This is the second parameter and is optional. This is used to declare parameters specified in @statement The rest of the parameters are the parameters that you declared in @params, and you pass them as you pass parameters to a stored procedure Declare @sql nvarchar(1000) Declare @params nvarchar(1000) Set @sql = 'Select * from Employees where [email protected] and [email protected]' Set @params = '@FirstName nvarchar(100), @LastName nvarchar(100)' Execute sp_executesql @sql, @params, @FirstName='Ben',@LastName='Hoskins' This is just the introduction to dynamic SQL. If a few things are unclear at the moment, don't worry. In our upcoming videos we will discuss the following 1. Implementing a real world "Search Web Page" with and without dynamic SQL 2. Performance and Security implications of dynamic sql. Along the way we will also discuss good and bad dynamic sql implementations. 3. Different options available for executing dynamic sql and their implications 4. Using dynamic sql in stored procedures and it's implications Once we discuss all the above, you will understand 1. The flexibility dynamic sql provides 2. Advantages and disadvantages of dynamic sql 3. When and when not to use dynamic sql
