Question

How do I convert the following query to delete the records that match ProjectID/Project_ID to 14?

select * from Project join Project_Assigned 
where Project.Project_ID = Project_Assigned.ProjectID 
and Project.Project_ID = 14;

The select statement works but when I try to convert it to instead delete the matching records I get ERROR 1064 (42000).

delete * from Project join Project_Assigned 
where Project.Project_ID = Project_Assigned.ProjectID 
and Project.Project_ID = 14;

Answer 1

Try this

DELETE FROM Project
WHERE Project_ID = 14
  AND Project_ID IN
    (SELECT ProjectID FROM Project_Assigned
     WHERE ProjectID = 14)
