Hi, I have a table that has the person, company and customer number. Thereare more than one rows for each customer. I want one row, with the corresponding company customer number. I performed a case statement, but am still getting back more than one row.
   Customer                    Company           CompanyID
1. Mouse, Mickey          CompanyA         CompanyA_ID
2. Mouse, Mickey           CompanyB        CompanyB_ID

I want Mouse, Mickey, CompanyA_ID  CompanyB_ID

SELECT Customer, CASE Company WHEN ComapnyA THEN CompanyA_ID END CompanyA_ID,
        CASE Company WHEN CompanyB THEN CompanyB_ID END CompanyB_ID
FROM CustomerTable

My result looks like this:
Mouse, Mickey      NULL      HI201
Mouse, Mickey      CB747      NULL

How can I group this to end up with one row?
I want Mouse, Mickey  CB747  H1201

Try this

SELECT Customer, MAx ( CASE Company WHEN ComapnyA THEN CompanyA_ID END) CompanyA_ID,
        Max( CASE Company WHEN CompanyB THEN CompanyB_ID END) CompanyB_ID
FROM CustomerTable
Group by Customer

That works but I realize that if I have a common customer name, it isn't really what I need. I need some other identifier, like the SSN. Once I bring that in, the solution will work perfectly. Thank you!
