Table 1
---------

Country region division amount
US 1001 01 300
FR 2001 01 100
IN 3001 02 200
JP 1002 01 500

Table 2
---------
Country region division division code
US 1001 01 T
FR 2001 01 P
IN 3001 02 P
JP 1002 01 T

Result
-------
Country region division amount
US 1001 01 300
JP 1002 01 500

Can someone help me to buid a query for this? The output of the 3rd table should be when country, region and division in two tables match and the division code is T.

Code:

                 AND A.REGION = B.REGION
                 AND A.DIVISION = B.DIVISION
                 AND B.CODE = 'T')

An inner join of A and B on country, region and division with a condition division = 'T' would be better than a co-related query ...
