Question

I have a simple table with 3 columns

PageDescription(varchar(50)) | ParentID (int) | CategoryID (int)

Here is the table data

Fruit||1
Apples|1|2

here is the query i’m running

SELECT PageDescription,(SELECT PageDescription
      FROM tblpages a
     WHERE a.ParentID = tblpages.CategoryID)
      AS 'Page Parent'
 FROM tblpages

This query does not stop processing, is there a better way to handle this query?

Answer 1

What you need is a join.

SELECT a.PageDescription, b.PageDescription as Parent
FROM tblpages a
LEFT JOIN tblpages b ON a.CategoryID = b.ParentID
