sql - Make Update with select statement in Mysql -

-

i trying update products category in database. error , and dont understand statement wrong. please help. find products have in name specific word , after update category products.

i want select ids sho_posts sho_posts.post_title contain part of word '%audio cd%' , after update sho_term_relationships.term_taxonomy_id value 2 sho_term_relationships.object_id=sho_posts.id

update sho_term_relationships     set term_taxonomy_id = 2  object_id = (select `id` `1876522_shoping`.`sho_posts` convert(`post_title` using utf8) '%audio cd%')

in clause, find ids update based on subquery results, use in instead of =

update sho_term_relationships     set term_taxonomy_id = 2    object_id in (       select `id` `1876522_shoping`.`sho_posts`        convert(`post_title` using utf8) '%audio cd%')

you use = if subquery return single row, won't work if subquery returns multiple rows. using in tests whether object id included in subquery results.
