Question

I have two tables:

Customer    Time    Program
-----------------------------------
1           8:05    a
2           9:38    b
3           10:45   c
4           12:00   a

Customer    Time    Program
-----------------------------------
1           11:30   d
5           1:45    e
6           9:45    f
7           2:15    g

I want my table to look like:

Customer    Time    Program
-----------------------------------
1           8:05    a
1           11:30   d
2           9:38    b
3           10:45   c
4           12:00   a
5           1:45    e
6           9:45    f
7           2:15    g

It’s really simple, but my time columns have different names in each of the tables and each table has a different set of programs so no program id will be in both tables.

Answer 1

Sounds like you want a UNION. UNION concatenates the rows of two tables, preserving the columns; JOIN associates columns of two different tables into rows.

You can rename columns in the SELECTs that make the union:

SELECT Customer, FirstTime AS Time, Program FROM Table1 UNION ALL SELECT Customer, SecondTime AS Time, Program FROM Table2
