Question

I have a table with 3 fields.

ID    Name     ParentID     Active
1     A        0            1
2     B        0            1
3     C        2            1

Now, I want a query where if there is row with ParentID > 0 and active then the row with its parent id (2) is skipped.

Please suggest a single MySQL query to achieve this.

Thank you,
Khuram

Edit: Thanks guys, finally solved and marked the correct answer.

Answer 1

this should work :

select * from test where id not in ( select parent_id from test where parent_id > 0 and active = 1 );
