How to insert multiple rows into a table based on a range of numbers

Question

I have to insert a specific number of rows into a SQL Server table.

DECLARE @val AS INT = 20, 
        @val2 AS VARCHAR(50), 
        @Date AS DATETIME = CONVER         


        

Answer 1

You can use a numbers table if you have one, use master.dbo.spt_values if you want one that has values till 2048, or create one of your own. In this case, you could use master.dbo.spt_values:

DECLARE @val AS INT=20, @val2 AS VARCHAR(50);
DECLARE @Date AS DATETIME = CONVERT(DATETIME,'02-05-2016');

SET @val2 = 'abc'

INSERT INTO dbo.YourTable
SELECT @val2, DATEADD(DAY,number,@Date)
FROM master.dbo.spt_values
WHERE type = 'P'
AND number <= @val;

Though since this starts at zero, you'll get 21 rows as a result
