Question

I have 2 tables, both with an employee_id and a task_group column. I need to build a query that returns a list of all the task_groups associated with a particular employee_id, whether they exist in either table.

Example:

Table 1:
Emp_ID | Blah_Blah
1234   | junk
6969   | crap

Table 2:
Emp_ID | Blah_Blah
1234   | crud
1234   | poop

And I need to build a query that will return this:

Query:
Blah_Blah
junk
crud
poop

Is this possible?

Answer 1

SELECT Blah_Blah from Table1 WHERE <some condition>
UNION
SELECT Blah_Blah from Table2 WHERE <some contition>
