After reading this article you will understand the basics of using the WHILE statement to write a loop within a stored procedure. All the examples for this lesson are based on Microsoft SQL Server Management Studio and the sample databases AdventureWorks and WideWorldImporters. Start learning SQL t...
Can we optimise While Loop in sql server for large number of data? Can we pass parameters to the trigger?(Beginner) Can we RAISERROR inside MERGE Statement Can we select Bottom 1000 rows of a database Table from SSMS 2008 R2? Can we set value in a variable inside a select statement ...
the TRY is successful. The CATCH block increments the retries counter and ends with a CONTINUE command that will re-execute the WHILE loop. You have code that does, in fact, retry the transaction–just like error 1205 tells us to do. But now the retry is done completely within T-SQL. ...

END LOOP; END initialize; / Because the processing in these two procedures is the same, it is logical to give them the same name. You can place the two overloadedinitializeprocedures in the same block, subprogram, package, or object type. PL/SQL determines which procedure to call by checkin...
In this exercise, you'll extend the Bicep code that you created previously so that you can deploy instances of your databases to multiple Azure regions. During the process, you'll: Move your existing Bicep code into a module. Create a new Bicep file with a copy loop to deploy the module...
