SQL Conditional column data return in a select statement

Solution 1:

You didn't mention your DBMS but a searched CASE statement works in all major DBMS's I know off.

SELECT  ID
        , CASE WHEN WorkStream = 'Internal'
               THEN WorkStream
               ELSE Assignee
          END AS Assignee
        , Workstream
FROM    assignees

Reference: MSDN

CASE

Evaluates a list of conditions and returns one of multiple possible result expressions.

Solution 2:

SELECT ID, 
       CASE WorkStream  WHEN 'Internal' THEN 'INTERNAL' ELSE Assignee as Assignee,    WorkStream  from assignees

I hope this help.
