Question

Please help me in resolving this query.

1. Table t1 having “t1c1” and “t1c2” columns.

2. Table t2 having “t2c2” and “t2c2” columns.

I have to insert values into t3 table having “t3c1″,”t3c2″,t3c3” columns.

The condition is that “t3c2” column values should be populated from “t1c2” column and “t3c3” column should be populated from “t2c2” column and “t3c1” should be populated from cursor values.

Can someone help in this? Is this possible?

Answer 1

This should work:

INSERT INTO t3 (t3c1, t3c2, t3c3)
SELECT currval, t1.t1c2, t2.t2c2
FROM t1, t2;

If you need to match only certain rows in t1 and t2, you can add:

WHERE t1.t1c1 = 'value'
  AND t2.t2c1 = 'value';
