Question

I understand that it’s a little rude to ask a question without any work to show, however I’m a little stumped and I need some help.

I need to delete a row from a mysql table if another field in another table is equal to 1

I have two tables table_1 and table_2

table_1 has two fields location and events

and table_2 has a field called location which is the same as location on table_1

I would like to delete one or more rows from table_2 if field location is the same as table_1 and events = 1

something like:

if `events` = 1 in `table_1` in 'location' `*`;
    delete row(s) from `table_2`
    where `location` is the same as `location` in `table_1`

Answer 1

DELETE t2
  FROM `table2` t2
  JOIN `table1` t1 ON t1.events = 1
                  AND t1.location = t2.location
