Question

Is it possible to get data from two exactly the same tables and print them? Currently I am able to search in TABLE1 but not in TABLE2 as well.

EDITTED

$name= $_SESSION['NAME'];

USER 
ID - NAME
1 - AAAA
2 - BBBB
3 - CCCC
4 - DDDD
5 - EEEE

TABLE1
ID - CODE - BUYSELL
1 -A - Buying
2 - A - Buying
3 - B Buying
4 - B - Selling
5 - C - Selling

 "SELECT * from TABLE1, TABLE2, USER WHERE '$person' = USER.NAME 
    AND TABLE1.ID = USER.ID"; 

TABLE2
ID - CODE - YESNO - CAR
1 - A - YES - VOLVO
2 - B - YES - FORD
3 - C - YES - M
4 - D - NO - BMW
5 - A - NO - VOLVO

(AND TABLE2.ID = USER.ID?????)

I want all to search both tables 1 and 2? But adding TABLE2.ID = USER.ID is basically looking for the same values in both tables. So if I wanted CODEs for USERID 1 from table1 and 2.

Is it possible under 1 query or 2?

Use UNION to combine the results of two queries into one:

(SELECT id, name AS value, "users" AS tbl_name FROM users WHERE ...)
UNION
(SELECT id, code AS value, "codes" AS tbl_name FROM codes WHERE ...)
