i have a notes column which contains text and has an id within the text, something like
“some random text (actvityid – 1234)”

i need to pull out the id 1234 in this case and update the activityid column within the same table.

my query looks like this

"UPDATE table_name SET activityId = {$f['activityId']} WHERE notes REGEXP '{$f['activityId']}' "

the problem with this is if $f[‘activityId’] is 34 or 123 for example it still updates the activityid column with that value. How can i do an exact match on “1234” and update only if it matches the whole string, here “1234”.

Many thanks.

    WHERE notes REGEXP CONCAT('(actvityid - ', {$f['activityId']}, ')')

    or

    WHERE notes REGEXP '[[:<:]]{$f['activityId']}[[:>:]]'

    [[:<:]] and [[:>:]] stands for word boundaries.
