Hi guys. I am really new to SQL.
Here is my question.

I have a function with 2 parameters which could do a calculation of the two numbers.
Now I want to use that function to calculate the value for (1,2),(2,3),(3,4).....(399,400) and make the result as a table.

I do not know whether SQL has any "FOR" clause to do that repeat.

anyone could help me?

Thanks a lot

This will generate the pairs that you want. You can also create a function that will return a table based on the pairs. The more specific you are in your request, the more we can help you get the answer you need.

DECLARE @x int
DECLARE @table TABLE (x int,y int)

SET @x = 1

WHILE @x < 400
BEGIN
INSERT INTO @table
SELECT @x,@x+1
SET @x = @x+1

END

SELECT * FROM @table

You could use a WHILE loop.

Or Jeff probably has a fancy CROSS JOIN solution he'll throw out.

EDIT: D'oh!

or

DECLARE @x int
DECLARE @table TABLE (x int,y int)

INSERT INTO @table
SELECT number,number+1 FROM master..spt_values
WHERE type='p' and number between 1 and 399

SELECT * FROM @table

if sql 2005. you can use CTE also

DECLARE @EndVal int
SET @EndVal=400
;With CTE (num1,num2)AS
(SELECT 1,2
 UNION ALL
 SELECT num1+1,num2+1
 FROM CTE
 WHERE num2+1<=400)

SELECT * FROM CTE
OPTION (MAXRECURSION 1000)

Also

select number as num1, number+1 as num2 from
(
	select row_number() over(order by name) as number from syscolumns
) as t
where number<400
