Hi,
I would like to know the SQL to delete all records in
TBL_CONTACT where TBL_USER.done = true

Structure of tables/query vs fields:

TBL_CONTACT             QRY_USER                TBL_USER
  userName   -------->  userName
                                       userId        -------->     userId
                                                                            done

             

DELETE *

FROM tbl_Contact

WHERE tbl_Contact.userName 

IN(select userName  from qry_User  ?????

     ??? where (qry_User.userId = tbl_User.userId,   tbl_User.Done=true);

I think this should do what you want. As always, test new code on a COPY of your database.

chuck
DELETE * FROM tbl_Contact WHERE tblContact.userName IN (SELECT userName FROM qry_User JOIN tblUser ON qry_User.userID = tbl_User.userID WHERE tbl_User.Done=True)

It's doesn't work.
I have an syntax error message. I can't find where.

DELETE * FROM tbl_Contact
WHERE tbl_Contact.userName IN (SELECT userName FROM qry_User JOIN tbl_User ON qry_User.userID = tbl_User.userID WHERE tbl_User.Done=True)

Try the subquery on its own.

chuck
SELECT userName FROM qry_User JOIN tbl_User ON qry_User.userID = tbl_User.userID WHERE tbl_User.Done=True

Something doesn't seem quite right.

Why is there a query between the two tables?
Are you saying that TBL_CONTACT and TBL_USER are not directly related?
Why not?

Perhaps I am not understanding something
This seems like a design issue.

Can you post the fields in these tables?

Hi Jeff,

You are right, it's not a good design. But it's temporary, it is for merging data from old database to a new one, with a new structure.

Thanks,
Carol

I did the subquery. Now it's working,  I had to replace JOIN by INNER JOIN
Thanks,
