Question

Tables i have
Table1 user_id, date
Table2 user_id, status

I need something like

UPDATE Table2 
   SET status = 2  
   WHERE user_id in ( {SELECT user_id FROM Table1 WHERE date > 0} )

In other words i need to see if date in table1 is more than 0000-00-00 then grab user_id of people who match this criteria and use them in table2 to set their status to 2.
Problem is that i need to do it for more than one user so request inside request does not work for me, it only works when there’s one row in result.

Answer 1

Are you using PHP or some other language to make SQL calls? If so, it might easier to just,

• firstly: select user ids from table 1
• secondly: loop through each row
• thirdly: execute the update
