You create a stored procedure named DeleteJobCandidate.
You need to ensure that if DeleteJobCandidate encounters an error, the execution of the
stored procedure reports the error number.
Which Transact-SQL statement should you use?

Option A

DECLARE @ErrorVar INT; DECLARE @RowCountVar INT; EXEC DeleteJobCandidate SELECT @ErrorVar = @@ERROR, @RowCountVar = @@ROWCOUNT; IF (@ErrorVar <> 0) PRINT N'Error = ' + CAST(@@ErrorVar AS NVARCHAR(8)) + N', Rows Deleted = ' + CAST(@RowCountVar AS NVARCHAR(8)); GO

Option B

DECLARE @ErrorVar INT; DECLARE @RowCountVar INT; EXEC DeleteJobCandidate SELECT @ErrorVar = ERROR_STATE(), @RowCountVar = @@ROWCOUNT; IF (@ErrorVar <> 0) PRINT N'Error = ' + CAST(ERROR_STATE() AS NVARCHAR(8)) + N', Rows Deleted = ' + CAST(@RowCountVar AS NVARCHAR(8)); GO

Option C

EXEC DeleteJobCandidate IF (ERROR_STATE() != 0) PRINT N'Error = ' + CAST(@@ERROR AS NVARCHAR(8)) + N', Rows Deleted = ' + CAST(@@ROWCOUNT AS NVARCHAR(8)); GO
