gizmola Posted May 17, 2020 Share Posted May 17, 2020 Please execute a "show create table user" and "show create table minfo" and post the results here so we can see what you are talking about. 1 hour ago, phpblues7 said: somehow u_id becomes primary of second table and primary of 1st table. how should i update the value of u_id in second table any help will be appreacited. You want to update user or minfo? What column(s) do you want to update? You can update a table utilizing a join to another table for the purposes of update. For example: UPDATE user JOIN minfo ON minfo.u_uid = user.u_id SET user.some_thing = minfo.some_thing Quote Link to comment https://forums.phpfreaks.com/topic/310799-database-and-php/#findComment-1578091 Share on other sites More sharing options...
