I've got a SQL DB that consists of multiple relational tables. You will find some fields within the master table that reference another table multiple occasions. For instance, say I've got a database of sales staff who're responsible of sales for multiple states. My database has fields for State1, State2, and State3 which map to a States table. I can not determine for that existence of me crafting a question to come back an archive with the enumerated states. Basically only needed one Condition area, I understand I'd do:

SELECT Master.Name, State.Enumeration AS 'State'
FROM MasterTable Master, StateTable State
WHERE Master.State1 = State.ID;

How do i expand this for those my Condition fields?

Thanks.

Coming back a column from each one of the unique joins towards the states:

select m.Name, s1.Enumeration as State1, s2.Enumeration as State2, s3.Enumeration as State3
from MasterTable m
left join StateTable s1 on m.State1 = s1.ID
left join StateTable s2 on m.State2 = s2.ID
left join StateTable s3 on m.State3 = s3.ID

Coming back 1 column of all of the states from the 3 major joins:

select m.Name, ISNULL(s1.Enumeration + ',','') 
               + ISNULL(s2.Enumeration + ',','') 
               + ISNULL(s3.Enumeration,'') as Enumeration
from MasterTable m
left join StateTable s1 on m.State1 = s1.ID
left join StateTable s2 on m.State2 = s2.ID
left join StateTable s3 on m.State3 = s3.ID

There's also column-queries...

select m.Name,
 ISNULL((select Enumeration from StateTable where ID = m.State1),'') as State1,
 ISNULL((select Enumeration from StateTable where ID = m.State2),'') as State2,
 ISNULL((select Enumeration from StateTable where ID = m.State3),'') as State3
from MasterTable m

You should utilize table aliases to be able to join multiple copies of the identical table:

   SELECT m.Name, 
          s1.Enumeration AS 'State1',
          s2.Enumeration AS 'State2'
     FROM MasterTable m
LEFT JOIN StateTable s1 = s1.id = m.state1
LEFT JOIN StateTable s2 = s1.id = m.state2

An INNER JOIN mandates that information is present - otherwise, the whole record is excluded. A LEFT JOIN is safer, like when the state1/2/3/etc enables NULLs...
