Question

I have two tables. One table (A) has n rows of data and the other table (B) is empty. I want to insert n rows into table B, 1 row for each row in table A. Table B will have a couple of fields from table A in it, including a foreign key from table A. In the end I want one row in B for each row in A. How can I write some TSQL to do this?

Answer 1

INSERT INTO TableB (ColA, ColB, ColC)
SELECT ColA, ColB, ColC
FROM TableA
