sql server - 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 Table1 to Table2 where their username = 'X' and password = 'X', so that they will no longer appear in Table1.

I'm using SQL Server 2008 Management Studio.

Answer 1

Should be possible using two statements within one transaction, an insert and a delete:

BEGIN TRANSACTION;
INSERT INTO Table2 (<columns>)
SELECT <columns>
FROM Table1
WHERE <condition>;

DELETE FROM Table1
WHERE <condition>;

COMMIT;

This is the simplest form. If you have to worry about new matching records being inserted into table1 between the two statements, you can add an and exists <in table2>.
