Liron Amitzi, Senior Database Consultant, Brillix LTD In 20 years of SQL tuning, this session’s speaker has learned many things. The number of elements that affect query tuning is huge: tables’ structure, indexes, optimizer behavior, and the SQL text itself are only some of them. This session takes a deep dive into specific examples of SQL tuning, based on real-life experience. Together, he and the audience members will identify a problem, analyze it (from understanding the schema and the application logic to looking at the object structure and SQL text), and fix it, while learning techniques and gaining some best practices for performance tuning.

The TEXT data types have not yet been discussed, but they are another string data type. They are similar to the VARCHAR data type with some minor differences that are important to know. The first thing to note is that there are four versions used to determine different sizes. From least to greatest size is TINYTEXT, TEXT, MEDIUMTEXT, LARGETEXT. These each have different maximum byte sizes: 255, 65535, 16 million something, and 4 billion something. You create a column as one of these data types just as you would with a varchar column. You work with them exactly the same, too. If that is the case, what are the primary differences between these and VARCHAR? The first difference is that VARCHAR is restricted by the row limit of a table. TEXT tables do not contribute nearly as much (max of 12 bytes) because the data is not stored inline in the table. This means that if you need to allow for extra space for other rows, you can use a TEXT column. And even though the table only contains a pointer to the data, it is all hidden to us and working with a TEXT column is the same as working with a VARCHAR column. The second primary difference is that TEXT data types do not allow for a default other than NULL. Thirdly, VARCHAR is limited to just under 64KB, whereas you can use MEDIUMTEXT or LARGETEXT to allow for more storage. So if what you are trying to store as an individual value is over 64KB, use a text column. Other than those three things, VARCHAR will usually work just fine for our text needs. Now, last thing is that these data types are often called CLOB data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Views: 830 Siva Academy
https://amzn.to/2Ph2CbI [affiliate link] We are back again with some issues and solutions. Actually one of my friends asked me regarding performance tuning if forms are opening slow. That time I gave him some ideas and promised him that I will back very soon with some more information. There are lots of factors which may impact the applications but there are some work around which can helpful fixed the issues. One more thing I would like to tell, friends I shared my knowledge’s as per my real time experiences and real life experiences. So, there is not like just copying and pasting the stuff. As already I have shared my real life time stories which I have learned from my life. So, let’s start now. Suppose, our forms are opening slow then what things we should be check and how to debug it. I will try to explain here and share my knowledge. I am sure; it will be useful because it’s having been experienced. 1. We should check which forms are opening slowly either any particular form or all forms. 2. If all forms are opening slowly for particular machine then clear the cache and try again. It can be machine speed slow, machine hardware and bandwidth speed. If all forms are opening slow and for all machine then we really need to check below things such as: A. Check whether Trace is enabled or disabled and if it is enabled then kindly disabled it. B. Check the top commands if any resources are consuming high CPU usage. C. Check for all Inactive Sessions if it’s there then kill those sessions. D. Check for deadlocks. E. Every user should close the forms and logout properly. But actually we don’t care. We just close windows tab at a time and left for break :D :P but that’s also impact our EBS internally. F. A programmer if ran any program with infinite loops then this also cause a performance issue. That’s why we need to write any program carefully. If program not properly then it may cause deadlock as also which I have explained it in my previous posts. G. It can also be because of increasing the number of users. Also need to check users have one active session. H. Check for the Performance Pack (Native I/O) is turned on for WLS. And most and always we use this method. If the users have issue for any custom forms then we should follow below steps which are easy and very effective. When he run the program that time you should follow below steps: 1. Enable the Trace file. Login to front-end - Help - Diagnostics - Trace - "Trace with Binds and waits” . Then there will be a trace file generate under below patch: $cd $ORACLE_HOME/admin/$CONTEXT_NAME/udump Now you can run either Trace Analyzer or tkprof as shown below commands: Trace Analyzer command: $sqlplus apps/apps_password SQL START TRCANLZR.sql UDUMP ora-data_ora1919.trc; TKPROF command: $ORACLE_HOME/admin/$CONTEXT_NAME/udump $tkprof ora-data_ora_1919.trc ora-data_ora_1919.txt explain=apps/apps_pwd Hope this may useful and helpful. We will come back again with new troubleshooting and solution as what we should do if forms opening slow after increasing the number of session.

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.

Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

Learn Database Export and Import using MySQL Workbench. Open MySQL Workbench and logged in to MySQL database server using 'root' username and password. In previous couple of videos we learned how to Create, Alter, Drop Databases and Tables and also how to Insert, Read, Update, Delete data rows using MySQL Workbench. In this lecture we will learn how to Export and Import the database using MySQL Workbench. First of all to Export the databases or tables, from top menu 'Server' select 'Data Export' Option, which opens a new window of data export settings and options. The left section on the window displays all the existing databases on our MySQL database server. When we select a database by clicking on it, it displays all the respected tables under the selected database. We can select one or multiple database check-boxes to include the database in the Export file. Under 'Export Options' section, You can change the default export path of you choice. I'll keep the default one. By selecting first option that is 'Export to Dump Project Folder'. MySQL Workbench will save the save all tables as separate SQL file under one folder. Which is useful when you will be importing or restoring the export file one by one table. I'll go ahead quickly and first save as 'Export to Dump Project Folder', MySQL Workbench displays the progress bar and log. Now, I'll again export the database using 'Export to Self-contained File' option. To demonstrate the import first I'll delete the existing 'students' table under 'mytestdb' database. Display database details by clicking on 'i' symbol, select 'tables' tab. Select and right click 'students' table, and click 'Drop Table' option, confirm and delete the table. Click 'refresh' to update the tables section and we have no table in our 'mytestdb' database. Now select the database and from 'data import' window, select 'import from dump folder. 'Load folder contents' and select only 'mytestdb' database and click start import button to import 'students' table again. Go to 'mytestdb' database information window again and click 'refresh' button to reload table list again. and the 'students' table is back.
