Question

I have two tables that I am joining with the following query…

select * 
  from Partners p 
inner join OrganizationMembers om on p.ParID = om.OrganizationId 
where om.EmailAddress = '[e-mail]' 
  and om.deleted = 0

Which works great but some of the columns from Partners I want to be replaced with similarly named columns from OrganizationMembers. The number of columns I want to replace in the joined table are very few, shouldn’t be more than 3.

It is possible to get the result I want by selectively choosing the columns I want in the resulting join like so…

select om.MemberID, 
       p.ParID, 
       p.Levelz, 
       p.encryptedSecureToken, 
       p.PartnerGroupName, 
       om.EmailAddress, 
       om.FirstName, 
       om.LastName 
 from Partners p 
inner join OrganizationMembers om on p.ParID = om.OrganizationId 
     where om.EmailAddress = '[e-mail]' 
       and om.deleted = 0

But this creates a very long sequence of select p.a, p.b, p.c, p.d, ... etc ... which I am trying to avoid.

In summary I am trying to get several columns from the Partners table and up to 3 columns from the OrganizationMembers table without having a long column specification sequence at the beginning of the query. Is it possible or am I just dreaming?

Answer 1

You are dreaming in your implementation.

Also, as a best practice, select * is something that is typically frowned upon by DBA’s.

If you want to limit the results or change anything you must explicitly name the results, as a potential “stop gap you could do something like this.

SELECT p.*, om.MemberId, etc..

But this ONLY works if you want ALL columns from the first table, and then selected items.
