-- First, let's declare the date range. I am declaring this -- here for the demo, but this could be done anyway you like. DECLARE @date_from DATETIME; DECLARE @date_to DATETIME; -- Set the start and date dates. In this case, we are using -- the month of october, 2006. SET @date_from = '2006-10-01'; SET @date_to = '2006-10-30'; -- insert random dates. insert into randomdate SELECT ( -- Remember, we want to add a random number to the -- start date. In SQL we can add days (as integers) -- to a date to increase the actually date/time -- object value. @date_from + ( -- This will force our random number to be GTE 0. ABS( -- This will give us a HUGE random number that -- might be negative or positive. CAST( CAST( NewID() AS BINARY(8) ) AS INT ) ) -- Our random number might be HUGE. We can't have -- exceed the date range that we are given. -- Therefore, we have to take the modulus of the -- date range difference. This will give us between -- zero and one less than the date range. % -- To get the number of days in the date range, we -- can simply substrate the start date from the -- end date. At this point though, we have to cast -- to INT as SQL will not make any automatic -- conversions for us. CAST( (@date_to - @date_from) AS INT ) ) )
