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.

see more on SET IDENTITY_INSERT on MSDN

Answer 2

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>.

Answer 3

If the two tables use the same ID or have a common UNIQUE key:

1) Insert the selected record in table 2

INSERT INTO table2 SELECT * FROM table1 WHERE (conditions)

2) delete the selected record from table1 if presents in table2

DELETE FROM table1 as A, table2 as B WHERE (A.conditions) AND  (A.ID = B.ID)

Answer 4

This is an ancient post, sorry, but I only came across it now and I wanted to give my solution to whoever might stumble upon this one day.

As some have mentioned, performing an INSERT and then a DELETE might lead to integrity issues, so perhaps a way to get around it, and to perform everything neatly in a single statement, is to take advantage of the [deleted] temporary table.

DELETE FROM [source]
OUTPUT [deleted].<column_list>
INTO [destination] (<column_list>)

Answer 5

You should be able to with a subquery in the INSERT statement.

INSERT INTO table1(column1, column2) SELECT column1, column2 FROM table2 WHERE ...;

followed by deleting from table1.

Remember to run it as a single transaction so that if anything goes wrong you can roll the entire operation back.

Answer 6

You could try this:

SELECT * INTO tbl_NewTableName 
FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Then run a simple delete:

DELETE FROM tbl_OldTableName
WHERE Condition1=@Condition1Value
