UPDATE `ikbfzposts` set `post_content` = REPLACE(`post_content`, `item="474"`, `item="mediaGrid_ScaleInWithIcon"`) WHERE `post_parent` LIKE `%56%`

şeklinde yazadım ama şu şekilde hata alıyorum:
SQL sorgusu:


UPDATE `ikbfzposts` set `post_content` = REPLACE(`post_content`, `item="474"`, `item="mediaGrid_ScaleInWithIcon"`) WHERE `post_parent` LIKE `%56%`
MySQL çıktısı: Belgeler

#1054 - Unknown column '%56%' in 'where clause'
