Here in the script above, we declare two variables: @CONDITION and @SQL_QUERY. The @CONDITION variable contains the WHERE clause in string format whereas the @SQL_QUERY contains the SELECT query. Next, these two variables are concatenated and passed to the sp_executesql stored procedure. Here...

You’ll use parameters “to pass” values from a call procedure to the current. Reference the parameters directly within your code, or assign them toT-SQL variables. Control of Flow Statements Allow you to use logic and looping constructs within your program. ...

This stored procedure takes no parameters at all. The calling application retrieves the value by using SQL Server’s return code support. Here a local variable named @cnt is declared using the DECLARE statement (all local variables in SQL Server are named starting with a_ @_). This variable...
