Question: DECLARE @Count INT SET @Count = 1 WHILE (@Count <= 5) BEGIN IF(@Count = 4) BREAK; PRINT @Count SET @Count = @Count + 2 END
This script is using T-SQL (Transact-SQL, which is Microsoft's and Sybase's proprietary extension to SQL). Here's a breakdown: - You declare and initialise a variable `@Count` as an integer and set its value to 1. - You're creating a while loop that will run as long as `@Count` is less than or equal to 5. - Inside this while loop, you have an IF statement that will stop the loop - `BREAK` - if `@Count` equals 4. - Then you print the current value of `@Count`. - Finally, you add 2 to `@Count` and the loop continues until `@Count` becomes greater than 5 or equals to 4. Please note, that SQL is a declarative language and not really designed for loop-based operations. Depending on your needs, there might be more efficient ways to accomplish what you want to do using set-based operations. However, if you're running this code on SQL Server, and have specific reasons to use loops, your script should work fine. The output of this script will be: ``` 1 3 ``` Because the loop breaks after `@Count` equals to 4.
