Any suggestion on Outer Join?

Question

Hi
Currently I need to join 2 tables , let's say Table A and Table B. But the result must contain the record which can be found in table A but not in table B and also record which can be found in Table B but not in Table A. Any suggestion?

Answer 1

SELECT
Column1,Column2, Column3, Column4, column5, column6
From TableA
minus
(SELECT
Column1,Column2, Column3, Column4, column5, column6
From TableA , TableB
WHERE TableA.Column1 = TableB.Column2
AND TableA.Column3 = TableB.column3
AND TableA.Column5 = TableB.column5
AND TableA.Column6 = TableB.Column6)
This would give you the rows that are there in table A but not in table b. Similarly you could find the rows for Table B which are not in TABLE A and then use the union operator.
Please check if it works.
