Does Boolean DataType Exists in SQL server

Does boolean data type exists in Sequel if y how? if N y?

How can i opt for boolean ( nearest ) ?

I've used Bit with not null

i want 2 display column of bit datatype into Checkbox .. Is is possible??

Whenver i bind the datatype of bit for checkbox it is throwing an error??

HELP ME HELP MEBit works fine as a boolean field, I don't have any problems. It is most likely a problem with nulls in your data. You can bind the bit filed to the checked property of a checkbox and you can put that checkbox in a repeater or datagrid using TemplateColumn.

Can you show your code. Or have you already resolved this issue. I know it is a bit old.

does a table exist?

Does anyone know if you can check if an object (eg a table) exists. I am
having trouble with procs that drop tables before creating them. Other users
get the message, "cannot drop table tblTest ... doesn't exist in the system
catalog".
I need to do something like,
If tblTest exists
Drop tblTest
...
then recreate the table

Say I want to check if table "Departments" exists (from the "Generate
SQL Scripts" option in Enterprise Manager):
if exists (select * from dbo.sysobjects
where id = object_id(N'[dbo].[Departments]')
and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[Departments]
Just substitute your table name (and owner [dbo]?) for Departments.
