return records even if rows are not contained in linked table

Hi, I am thinking this is a pretty easy question.

I have a table called tblparents

I have a table called tblchildren

The field that links tblparents to tblchildren is household.

I need to return all of the records in tblparents even if no children exist in tblchildren.  Right now when I run the query I only get results in tblparents where rows exist in tblchildren.

Help is greatly appreciated!

Use LEFT JOIN to ensure that all rows are included in the return set from the object to the left of LEFT.
SELECT p.*, c.whatever
FROM tblParents p
   LEFT JOIN tblchildren c ON p.household = c.household

Open in new window


Note this will return more than one row if a given parent has more than one children.

As an aside, to view some pretty pictures that will help you understand the different joins, go to images.google.com and search for 'SQL Join Types'.  There's many good pictorals out there, and my grabbing one and posting it here would violate copyrights.

Can you post the query you're running that doesn't get all of the parents?
