enter image description herei have table 4 columns , 8000 rows of data datetime column 2016-01-05. want copy these 8000 rows of data days of january 1st 31st.

meaning, should have 8000 * 31 days of data though same data.

how do without using excel document.

first, create temporary date table values each day in january 2016.

create table #tempdate (datecol datetime)  declare @day int = 1 declare @date date = '2016-01-01' while @day <= 31 begin     insert #tempdate     values (@date)     set @day +=1     set @date = dateadd(dd,1,@date) end

next, can select desired columns , cross join others have said well. should cartesian product between 2 tables (8000 x 31 rows).

select c.column1, c.column2, c.column3, t.datecol #tempdate t cross join yourtablename c
