Hi,
I'm a beginner with t sql in sql server 2005.
I've try to create a simple script who creates some table but i have a problem !!!
here is it my code :
declare @t varchar(500)
set @t = @tblApplication + @PERS_SITE => contains some value
CREATE TABLE [dbo].[@t](
[Person_ID] [int] NOT NULL,
[MayLog] [bit] NOT NULL,
[Rubrique] [bit] NOT NULL CONSTRAINT [@constraintName] DEFAULT ((1))
ON [PRIMARY]
but when i execute the script by pressing F5 and refresh the database i see a new table NEW CREATED NAMED => @t !!!!
i can 't understand !!
any idea ?
Thanls for your time
christophe

The brackets are telling the database engine that all characters between them are part of the table name. Thus you have @t as your table name instead of your variable.

In order to create a table dynamically as you are looking to do - you would need to use dynamic sql statements to do so.

Something like this:

declare @t varchar(max)

declare @n varchar(50)

set @n = 'MyAppMyTable'

select @t = 'create table [' + @n + '] ( [Person_ID] [int] NOT NULL,

[MayLog] [bit] NOT NULL,

[Rubrique] [bit] NOT NULL CONSTRAINT [@constraintName] DEFAULT ((1))

ON [PRIMARY]'

exec(@t)
