Whenever we perform a division in SQL, we must remember to handle a ‘divide by zero’ error. Even though there is no data with value zero in the denominator, for now, we must handle the ‘divide by zero’ error
you may notice that the parallel query is forced to run in serial mode because of the lack of parallel worker threads. In this situation, a memory grant usage-warning feature may cause the divide-by-zero error.
GO SET ANSI_WARNINGS ON; GO PRINT 'Testing NULL in aggregate'; GO SELECT a, SUM(b) FROM T1 GROUP BY a; GO PRINT 'Testing String Overflow in INSERT'; GO INSERT INTO T1 VALUES (3, 3, 'Text string longer than 20 characters'); GO PRINT 'Testing Divide by zero'; GO SELECT a / ...
When an UPDATE statement encounters an arithmetic error (overflow, divide by zero, or a domain error) during expression evaluation, the update isn't performed. The rest of the batch isn't executed, and an error message is returned. If an update to a column or columns participating in a cl...
