MySQL update with two subqueries
- by Julian Cvetkov
I'm trying to update one column of MySQL table with subquery that returns a date, and another subquery for the WHERE clause.
Here is it:
UPDATE wtk_recur_subs_temp
SET wtk_recur_date = (SELECT final_bb.date
FROM final_bb, wtk_recur_subs
WHERE final_bb.msisdn = wtk_recur_subs.wtk_recur_msisdn)
WHERE wtk_recur_subs_temp.wtk_recur_msisdn IN (select final_bb.msisdn
from final_bb)
The response from the MySQL engine is "Subquery returns more than 1 row".
