SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online
 
08:41
http://www.sqltrainingonline.com SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online In this video, I show you how to do a SQL Date Comparison in SQL Server when your Datetime has an actual time in it. I also include the latest trick that will make this easier if you are using SQL Server 2008 or SQL Server 2012. How do you compare a Datetime in SQL Server? A SQL Datetime stores both Date and Time. So when you are filtering using the SQL Where clause, you have to know if you Datetime is storing the time also. Let's take a look at the employee table in SQL Training Online Simple DB The column we are looking at is the hire date. I want to go after the person who was hired on February, 22 2005. So, I use the following SQL. select * from employee where hire_date='02/22/2005' Now, this works because we don't have any times stored in this column. But, if I change the record from 2005-02-22 00:00:00.000 to 2005-02-22 08:22:25.000 and rerun the query, you see that I don't get any results. That is because the value of 02/22/2005 is really 2005-02-22 00:00:00.000 and I just changed the hire_date to include a time other than 00:00:00.000. So, I have to tweak my query to use a greater than and less than sign. This works. But, to really understand what is going on, let me show you what SQL Server really sees. There are other ways, and in this StackOverflow article you can read more about these other ways. But, I want to point out a few. If you are working in SQL Server 2005 or earlier, the following is supposed to be the fastest performing way to do this. select datediff(dd,0, hire_date),* from employee where dateadd(dd,0, datediff(dd,0, hire_date)) = '2005-02-22' But, if you are working in SQL Server 2008 or SQL Server 2012, they have introduced an actual Date datatype that doesn't include the Time portion. Since this is the case, you can use the CAST function to remove the time from the Datetime. Here is the SQL to do that. select * from employee where CAST(hire_date AS Date) = '2005-02-22' And that's it. If you enjoy the video, please give it a like, comment, or subscribe to my channel.

Oracle TO_CHAR Function
 
04:13
https://www.databasestar.com/oracle-to_char/ The Oracle TO_CHAR function is a common and useful string manipulation function. It allows you to convert a number or a date value into a string value. It allows you to take a number or a string, and convert it to a VARCHAR2 data type. The syntax of the function is: TO_CHAR( input_value, [format_mask], [nls_parameter] ) The parameters are: - input_value: this is the value to convert to a VARCHAR2 value. It can be one of many different number or date data types. - format_mask is an optional parameter and allows you to specify the format to display the output as. If this is omitted, the function uses a default format. - nls_parameter: this is also optional and lets you determine a regional parameter for displaying the output value. The format mask helps you determine what your output is displayed as. For example, if you provide the date of May 3rd, and the output is ‘03/05/2018’, how do you know if this is May 3rd or March 5th? Using a format mask can specify which format is used. The function is similar to the TO_NUMBER and TO_DATE functions, in that they both convert a specific data type. For more information about the Oracle TO_CHAR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_char/

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

Course Description – sql2 COURSE DESCRIPTION: Introduction to Oracle9i: SQL consists of two modules, Introduction to Oracle9i: SQL Basics andOracle9i: Advanced SQL. Introduction to Oracle9i: SQL Basics covers creating database structures and storing, retrieving, and manipulating data in a relational database. Oracle9i: Advanced SQL covers advanced SELECT statements, Oracle SQL and iSQL*Plus Reporting.For people who have worked with other relational databases and have knowledge of SQL, another course, called Introduction to Oracle9i for Experienced SQL Users is offered. This course covers the SQL statements that are not part of ANSI SQL but are specific to Oracle.   The Oracle server extends the data modeling capabilities to support an object relational database model that brings object-oriented programming, complex data types, complex business objects, and full compatibility with the relational world. It includes several features for improved performance and functionality of online transactionprocessing (OLTP) applications, such as better sharing of run-time data structures, larger buffer caches, and deferrable constraints. Data warehouse applications will benefit from enhancements such as parallel execution of insert, update, and delete operations; partitioning; and parallel-aware query optimization. COURSE OBJECTIVES: in this course In Oracle9i, you can include the time zone in your date and time data, and provide support for fractional seconds. Three new data types are added to DATE: TIMESTAMP TIMESTAMP WITH TIME ZONE (TSTZ) TIMESTAMP WITH LOCAL TIME ZONE (TSLTZ) Oracle9i provides daylight savings support for datetime data types in the server Create, maintain, and use sequences Create and maintain indexes Create private and public synonyms WHO SHOULD ATTEND?   COURSE OUTLINE:   Creating Views Other Database Objects Controlling User Access SQL Workshop Using SET Operators Oracle9i Datetime Functions Enhancements to the GROUP BY Clause Advanced Subqueries Hierarchical Retrieval Oracle9i Extensions to DML and DDL Statements

SQL Script to create Employees table Create table Employees ( ID int, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (1, 'Mark', 'Hastings', 'Male', 60000) Insert into Employees values (2, 'Mary', 'Lambeth', 'Female', 30000) Insert into Employees values (2, 'Mary', 'Lambeth', 'Female', 30000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) Insert into Employees values (3, 'Ben', 'Hoskins', 'Male', 70000) The delete query should delete all duplicate rows except one. Here is the SQL query that does the job. PARTITION BY divides the query result set into partitions. WITH EmployeesCTE AS ( SELECT *, ROW_NUMBER()OVER(PARTITION BY ID ORDER BY ID) AS RowNumber FROM Employees ) DELETE FROM EmployeesCTE WHERE RowNumber ] 1

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/05/part-1-how-to-find-nth-highest-salary_17.html This is a very common SQL Server Interview Question. There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) 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 To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

Oracle SQL MERGE Statement
 
07:52
https://www.databasestar.com/oracle-merge-sql/ In this video, we’ll learn what the Oracle MERGE statement does and how you can use it. What is the MERGE statement? It’s a statement that lets you either insert or update data in a table - all in a single statement! It’s helpful if you’re using an ETL (Extract Transform Load) process when creating or updating a data warehouse. It’s also helpful when loading data into your own database if you’re not creating a data warehouse. It allows you to prevent duplicate data and ensure you have up-to-date data in your table. The syntax looks like this: MERGE INTO table_name USING table_name ON (condition) WHEN MATCHED THEN update_clause DELETE where_clause WHEN NOT MATCHED THEN insert_clause [LOG ERRORS log_errors_clause reject_limit integer | unlimited ] In this video, I also show an Oracle SQL MERGE statement example, so watch the video to find out more. For more information on the MERGE statement and how you can use it in your queries, read the related article here: https://www.databasestar.com/oracle-merge-sql/
