hi,
I have a field which is a genome sequence and I need to check if each of
the entries made for the sequence field contains only a,t,c or g in the string
and no other characters.
how will i give the query???
It depends. You can find matching values with
WHERE col_name REGEXP '^[atcg]+$'
but you don't say what you want for output, so beyond that it's difficult to say what the rest of the query should look like.
