Question

I have two tables ..TableA and TableB

in TableA.. I have 5 fields.. ( Empty ) (only structure having Autoincrement-ID field)

in TableB ..I have 7 Fields ( Full ..1 million Recs.)

TableA is Empty .. i want to add a complete column from TableB ..

i.e the field’ID’ in the TableB shud be inserted inside the the field’Value’ in the TableA..

i.e complete column’ID’ from TableB shud be copied/inserted inside the TableA as column’Value’

There is no match case here so i cannot use WHERE clause…

What exactly shud i use outerjoin or innerjoin or full join..

Pls advise.

Answer 1

INSERT INTO TableA(value) SELECT id FROM TableB
