I need to extract rows from one table which are not in other. How do i do this?
I have two tables A and B.
B has uniq index on Col A, B, C and D.
A is a temporary table and has around 50000 rows. We need to insert all those rows from A into B which are not in B. Rows that are already there with a different value for colD need to be inactivated.
Also I have a table C which has only A, B ,and D
from table B I have to insert all those into Table C if Column D is different for a given combination of colA and colB.
Thanks!
Vinay.
