mysql - SQL select rows where at least one value is something per id -
i've looked @ other answers these questions , haven't seen 1 fits want.
so have table ids , states , multiple records per id different state values. how return table records @ least 1 record id value? example, if have
id|state 1|ca 1|zz 1|zz 2|ny 2|ca 3|ny 4|il 4|zz
and ones had record of being in ny
id|state 2|ny 2|ca 3|ny
you can try this:
select * tablename id in (select id tablename state = 'ny');
