Question

One attribute in a table became corrupted after a certain point in a table of mine. I want to delete every pat_coun attribute if it has an ID that begins with 11 (number, not text). So I don’t want to get rid of any of the records in the database, just clear out the attribute pat_coun if it’s ID begins with 11

DELETE pat_coun from myTable
WHERE id %11

Just want to make sure this is right before I go deleting stuff. Thanks.

To clear out an attribute, do NOT use the DELETE function! That deletes a row from your table!

You need to use UPDATE instead:

UPDATE myTable
SET pat_coun = NULL
WHERE id LIKE '11%'
