I know we can simply create a new table and copy the old table by doing
select * into tbl2 from tbl1
i would like to check if table tbl2 exists, if it does then copy all the rows, if it doesn't then create a new one without having to specify the column names in tbl2 since I'm copying all the columns from tbl2 in tbl1. then, I would like to drop old table(tbl1)
if not exists(select * from tbl1 where id = 1)
create table tbl2()
drop tbl1
go
IF (EXISTS (SELECT *
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'tbl2'))
BEGIN
-- tbl2 exists, so just copy rows
INSERT INTO tbl2 SELECT * FROM tbl1;
END
ELSE BEGIN
-- tbl2 doesn't exist, so create new table tbl2 and copy rows
SELECT * INTO tbl2 FROM tbl1;
DROP tbl1;
END
This won't copy indexes, keys, etc though - just the column names on create (in the else branch).
This could be done using user defined variable which is faster as already mentioned in the previous answer. This needs creating incremental variable for each group depending on some ordering. And from the given data set its user and date. Here how you can achieve it select user, date, purchase_count...

What happens if you change all of the filters to use 'LIKE': if (DropDownList1.SelectedValue.ToString().Equals("Start")) { FilterExpression = string.Format("Start LIKE '{0}%'", TextBox1.Text); } Then, you're not matching against an exact date (at midnight), but matching any date-times which start with that date.
