This video is an introduction to Oracle SQL Performance Tuning for Developers: http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027 6+ Hours of Video Instruction The focus of Oracle SQL Performance Tuning for Developers LiveLessons is to illustrate coding techniques that ensure a consistent response time between instances and releases of the Oracle database. This course works closely with performance tuning of actual SQL statements. Description In this video training, Dan Hotka starts out with a complete overview of the Oracle architecture so students can get an understanding how their SQL and applications can take advantage of the computing environment. This course then goes in-depth on understanding and controlling the Explain Plan, which is how and in what order Oracle retrieves data. The discussion includes considerable detail, with SQL examples, on how the optimizers--both rule-based and cost-based, but mostly cost-based--make their decisions. Students will work with a variety of SQL statements, reviewing Explain Plans and making changes to make these SQL statements perform better. Lectures include index design, using hints and coding style to control the Explain Plans, and how to use useful tools such as index monitoring, SQL Trace, and the PL/SQL profiler. This LiveLessons course takes a close look at indexes: how Oracle selects them, why they are sometimes not used, and how to tell if indexes are being used. This course includes Oracle10g, Oracle11g, and Oracle12c SQL tuning topics. Skill Level Intermediate Learn How To Read and understand Explain Plan content Review an Explain Plan and tell quickly if this is a good plan Understand a good index column candidate from a not-so-good candidate Quickly tell the likelihood if your SQL will use an existing index Use coding and a variety of Hints (directives) that can produce better performing SQL Execute and interpret SQL trace output Who Should Take This Course Oracle programmers Oracle database administrators who need additional training on SQL tuning Course Requirements Working knowledge of the SQL query language http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027

debugging in ssms debugging t-sql code t sql debug stored procedure sql server management studio debug stored procedure how to debug t sql debug in sql server management studio In this video we will discuss how to debug stored procedures in SQL Server. Setting up the Debugger in SSMS : If you have connected to SQL Server using (local) or . (period), and when you start the debugger you will get the following error Unable to start T-SQL Debugging. Could not connect to computer. To fix this error, use the computer name to connect to the SQL Server instead of using (local) or . For the examples in this video we will be using the following stored procedure. Create procedure spPrintEvenNumbers @Target int as Begin Declare @StartNumber int Set @StartNumber = 1 while(@StartNumber [ @Target) Begin If(@StartNumber%2 = 0) Begin Print @StartNumber End Set @StartNumber = @StartNumber + 1 End Print 'Finished printing even numbers till ' + RTRIM(@Target) End Connect to SQL Server using your computer name, and then execute the above code to create the stored procedure. At this point, open a New Query window. Copy and paste the following T-SQL code to execute the stored procedure. DECLARE @TargetNumber INT SET @TargetNumber = 10 EXECUTE spPrintEvenNumbers @TargetNumber Print 'Done' Starting the Debugger in SSMS : There are 2 ways to start the debugger 1. In SSMS, click on the Debug Menu and select Start Debugging 2. Use the keyboard shortcut ALT + F5 At this point you should have the debugger running. The line that is about to be executed is marked with an yellow arrow Step Over, Step into and Step Out in SSMS : You can find the keyboard shortcuts in the Debug menu in SSMS. Let us understand what Step Over, Step into and Step Out does when debugging the following piece of code 1. There is no difference when you STEP INTO (F11) or STEP OVER (F10) the code on LINE 2 2. On LINE 3, we are calling a Stored Procedure. On this statement if we press F10 (STEP OVER), it won't give us the opportunity to debug the stored procedure code. To be able to debug the stored procedure code you will have to STEP INTO it by pressing F11. 3. If the debugger is in the stored procedure, and you don't want to debug line by line with in that stored procedure, you can STEP OUT of it by pressing SHIFT + F11. When you do this, the debugger completes the execution of the stored procedure and waits on the next line in the main query, i.e on LINE 4 in this example. To stop debugging : There are 2 ways to stop debugging 1. In SSMS, click on the Debug Menu and select Stop Debugging 2. Use the keyboard shortcut SHIFT + F5 Show Next Statement shows the next statement that the debugger is about to execute. Run to Cursor command executes all the statements in a batch up to the current cursor position Locals Window in SSMS : Displays the current values of variables and parameters If you cannot see the locals window or if you have closed it and if you want to open it, you can do so using the following menu option. Locals window is only available if you are in DEBUG mode. Watch Window in SSMS : Just like Locals window, Watch window is used to watch the values of variables. You can add and remove variables from the watch window. To add a variable to the Watch Window, right click on the variable and select "Add Watch" option from the context menu. Call Stack Window in SSMS : Allows you to navigate up and down the call stack to see what values your application is storing at different levels. It's an invaluable tool for determining why your code is doing what it's doing. Immediate Window in SSMS : Very helpful during debugging to evaluate expressions, and print variable values. To clear immediate window type ]cls and press enter. Breakpoints in SSMS : There are 2 ways to set a breakpoint in SSMS. 1. By clicking on the grey margin on the left hand side in SSMS (to remove click again) 2. By pressing F9 (to remove press F9 again) Enable, Disable or Delete all breakpoints : There are 2 ways to Enable, Disable or Delete all breakpoints 1. From the Debug menu 2. From the Breakpoints window. To view Breakpoints window select Debug =] Windows =] Breakpoints or use the keyboard shortcut ALT + CTRL + B Conditional Breakpoint : Conditional Breakpoints are hit only when the specified condition is met. These are extremely useful when you have some kind of a loop and you want to break, only when the loop variable has a specific value (For example loop varible = 100). How to set a conditional break point in SSMS : 1. Right click on the Breakpoint and select Condition from the context menu 2. In the Breakpoint window specify the condition Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures_28.html

Download the presentation slides, code samples, and a free download of DB Optimizer at http://embt.co/1M7vSe6 Most of us have been in the situation where, for no apparent reason, performance for key SQL takes a nose-dive after having previously performed well. So, how do you handle this situation and stabilize performance back to acceptable levels? One approach is to go back in time using execution data stored in AWR. In many cases, AWR may contain what you need to revert your problem SQL to a better performing alternative.

SQL is the winning language of Big Data. Whether you’re running a classic relational database, a column store (“NewSQL”), or a non-relational storage system (“NoSQL”), a powerful, declarative, SQL-based query language makes the difference. The SQL standard has evolved drastically in the past decades, and so have its commercial and open source implementations. In this fast-paced talk, we’re going to look at very peculiar and interesting data problems and how we can solve them with SQL. We’ll explore common table expressions, hierarchical SQL, table-valued functions, lateral joins, row value expressions, window functions, and advanced data types, such as XML and JSON. And we’ll look at Oracle’s mysterious MODEL and MATCH_RECOGNIZE clauses, devices whose mystery is only exceeded by their power. Most importantly, however, we’re going to learn that everyone can write advanced SQL. Once you learn the basics in these tricks, you’re going to love SQL even more.
