Question

Hi
This statements are executed in Stored Procedure. I am passing parameters and It is doing multiple updates and inserts.
I will appreciate some suggestions to
-improve the performance,
-reduce the execution time
-and improvements in code structure.
There are three different tables: Table_01, Table_02, Table_03.

INSERT INTO Table_01(
    TestID,     
    TestData,
    CurrentDate,
    UserID,
    Status
) VALUES (
    @testID,        
    @testData,
    @iDateTime,
    @userID,
    @Status
)

IF (@Status = 1) 
BEGIN 

    DELETE FROM
        Table_02
    WHERE 
        TestID = @testID

    UPDATE Table_03
    SET
        Status = 1,
        Date = @iDateTime,
        Work = 0
    WHERE
        TestID = @testID
END

Not really much to tweak to be honest: it’s straightforward code, nothing fancy

You can add a transaction so it all writes succeed or all writes fail.

If you find the code slow then I’d look at indexes on TestID and do you have triggers
