code block to execute if the condition is true The basic syntax of the SQL Server IF statement is simple: IF condition This control-of-flow statement allows you to handle different scenarios and make decisions within your SQL Server scripts or stored procedures. ![]() SQL Server IF statement provides a way to execute code blocks based on specific conditions. By utilizing these statements effectively, developers can write more sophisticated and flexible code that can adapt to different scenarios and requirements. Control-of-flow statements provide the ability to make decisions based on conditions, iterate over sets of data, handle errors, and control the flow of program execution. They enable the implementation of conditional logic, looping, and branching, which are essential for designing complex and dynamic queries. Overall, the control-of-flow statements allow developers to have more control over the query execution. It allows you to bypass certain codes within a loop based on specific conditions. CONTINUE: Skips the current iteration of a loop and proceeds to the next iteration.It is often used in conjunction with conditional statements to terminate a loop prematurely. BREAK: Exits the innermost loop or switch statement in which it is located.The TRY block contains the code that might cause an error, and the CATCH block is executed if an error occurs, allowing you to handle the error and perform necessary actions. TRY.CATCH: Implements error handling in T-SQL.It allows you to jump to a specific part of the code based on a certain condition or requirement. GOTO: Transfers the control of execution to a labeled statement within the same script or stored procedure.BEGIN.END: Defines a block of code that can be used with other control-of-flow statements to group multiple statements into a single logical unit.It allows you to define different actions based on different conditions or values. CASE: Provides a way to perform conditional logic based on multiple conditions.The code block is executed repeatedly until the condition evaluates to false. ![]()
