How to Determine the Success of a MySQL DELETE Operation
When executing a DELETE statement in MySQL using PHP, determining its success can prove beneficial.
Using MySQL Query Functions
To ascertain the outcome of a DELETE operation using mysql_query, the function returns:
- TRUE: Operation succeeded.
- FALSE: Operation failed due to an error.
Alternatively, when employing PDO::exec, the function returns:
- Number of rows modified or deleted: Positive integer indicating success.
- 0: No rows were affected.
mysql_affected_rows Function
To verify the impact of a DELETE operation more precisely, consider using the mysql_affected_rows function. This function returns:
- Number of rows affected: Positive integer indicating the number of rows deleted.
- 0: No rows were deleted.
