why does when I put the command at VB2008 error pop-ups saying:

Conversion failed when converting the nvarchar value 'ID' to data type int.

When I run it on SQL 2008 it works fine.

VB

ds2 = MonthCalendar1.SelectionStart.ToShortDateString

SQL

IF NOT EXISTS(SELECT 0 FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = "TimeTB" AND COLUMN_NAME = " & ds2 & ")BEGIN ALTER TABLE TimeTB ADD ["& ds2 &"] nvarchar(50) DEFAULT 'FREE' NOT NULL END

The only thing that occurs to me is your use of '&'. What is this for? Do you actually want "& 04/02/2011 &" as your column name?

Even if this is valid the string you are looking for is slightly different (it has extra spaces before the first '&' and after the last one) from the one you are adding, I don't know if this is deliberate.
