Move SQL data from one table to another

Question

I was wondering if it is possible to move all rows of data from one table to another, that match a certain query?

For example, I need to move all table rows from Tab

Answer 1

Yes it is. First INSERT + SELECT and then DELETE orginals.

INSERT INTO Table2 (UserName,Password)
SELECT UserName,Password FROM Table1 WHERE UserName='X' AND Password='X'

then delete orginals

DELETE FROM Table1 WHERE UserName='X' AND Password='X'

you may want to preserve UserID or someother primary key, then you can use IDENTITY INSERT to preserve the key.
