It is not inserting NULL. when $login is NULL or blank, then a a record, with emplogin equal to a string of zero characters is inserted, which is valid. A string with zero characters is NOT a NULL value. So, it is accepted.

Hi, I'm getting a weird effect in the task manager app we use internally. I have a table emp_tasktime which records work sessions on tasks. The column emplogin varchar(25) not null is intermittently allowing null entries for just one employee. The insert statement is: INSERT INTO emp_tasktime set task_id='$task_id_link', emplogin='$login', date_start='$date', time_start=sec_to_time(time_to_sec('$time')+10800) $login is the employee name. If it was blank, the sql statement would fail, but it doesn't, but when I look at the table the emplogin field is SOMETIMES blank where is should be "Robyn". I'm perplexed.
