Question

I have two tables like this:-

TABLE A

CODE          DESC
----          ----
A001          BLACK
12AA          SOFT
B001          GREY
13SW          ANTIQUE
B011          BROWN
23WQ          HARD

TABLE B

NO      MODEL         COLOR     FINISH
--      -----         -----     ------
01      QWER          A001      12AA
02      ASDF          B011      13SW
03      ZXCV          B001      12AA
04      POIU          A001      23WQ

I wish to hv an output like this using SQL:-

NO      MODEL         COLOR     FINISH
--      -----         -----     ------
01      QWER          BLACK      SOFT
02      ASDF          BROWN      ANTIQUE
03      ZXCV          GREY       SOFT
04      POIU          BLACK      HARD

Answer 1

Research SQL joins:

select b.no, b.model, a1.desc as 'color', a.desc as 'finish' 
from tableb b
inner join tablea as a
on b.finish = a.code
inner join tabla as a1
on b.color = a1.code

This query ‘merges’ the two tables based on a common indentifier (in this the code).
