You can do like this also

INSERT INTO Tablename( COLUMNName )

VALUES ( 0 ),(1),(2)......(1000)

That is really funny 😀

Do you want a query which will build this kind of statement dynamically or you prefer to type it in? :hehe:

Or you could try this undocumented procedure.

exec Insert1000RowsInATableWithoutAnyLoop

Try selecting approximately 1000 from rows from other table (if you have any) and then do .../

INSERT INTO TESTTABLE(Col1)

SELECT Tcol1 FROM OTHER TABLE WHERE .....

If you need this for any specific purpose, please provide the details..........

Try this. Given at least 1000 records exist in tblTest, this would insert 1000 rows into temporary table tblTemp.

SELECT column1 INTO #tblTemp

FROM tblTest

WHERE column1 IN

(SELECT TOP 1000 [col1]

FROM tblTest)

These are the kinds of interview questions that I ask to find out how much a person may know about set based programming.

Please see the following article for multiple answers to your question. If you actually study the article, it will change your career for the better... seriously.

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
