I have a table with 2 date fields.
I used the following query to update one
update day19 set bdate = ddate+1 where narration like "th card%"
I received the errors attached.
I altered the date of the row giving error using sql manager but the error shifted to 31st May.
It seems the date calculator gets stuck at month ends.
Since there are no specific data files or error logs required I have not attached them.
If required I can send them
