Can I perform multiple row join?


Folks,
I have two tables - one called parent, the other called group.

table group is made up of ID,parentID,gro upHash and groupName.

table parent is made up of ID,title,group1 Hash,group2Hash ,group3Hash (and
other columns)

Each of the group hashes in table parent correspond to a group hash in table
group (ie parent.group1Ha sh exists in/as group.groupHash and
parent.group2Ha sh also exists (on another row) in/as group.groupHash ).

This means table parent can have up to three groupHash's noted in a single
row and each of these groupHash's will have its name in a corresponding row
in table group (using groupHash as key).

Can I perform a select whereby I read a row from parent and use its
group1Hash, group2Hash and group3Hash to retrieve their corresponding names
from table group (all in one select statement)? Or must I perform three or
four individual selects to get the desired values from the two tables.

All help, via the newsgroup is much appreciated,

Thanx

I have a query that returns multiple identical records, however it should only return one. Indeed there is only one record for the OrderActionTypecode of 'P' yet there are two orderactions so it returnd both. Oddly the second query returns only the desired single record but wihtout all the additional fields I need. Does the Inner join somehow mess with the query? Thanks

I have worked for hours on trying to find a solution and have not figured it out. I am working in Access 2003.

I also need to use a query instead of a form because I then need to be able to export...

I'm kind of comfortable with basic joins, but a current project requires a complex query of many tables.
