I need to create table with the data information passed under a proc as follows:
CREATE PROCEDURE [dbo].[_pXymd]
@Fname char(8)
AS
BEGIN
SET NOCOUNT ON
DECLARE @pk char(11)
SELECT @pk='PK_'+@Fname
CREATE TABLE [dbo].[@Fname] (
[ICno] [int] NOT NULL DEFAULT (0),
[Xdate] [smalldatetime] NOT NULL,
[Rem] [nvarchar] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL DEFAULT ('')
) ON [PRIMARY]
ALTER TABLE [dbo].[@Fname] WITH NOCHECK ADD
CONSTRAINT [@PK] PRIMARY KEY CLUSTERED
(
[ICno],
[Xdate]
) ON [PRIMARY]
END
GO
=========================
When executing: EXEC _pXymd '_X080804'
The database can create a table named @Fname but not _X080804 that I want.
Can any expert help me to modify the codes to create the table with table name passed by Proc ?
Thanks so much.

Put the table name in brackets.

It can't work !!

A table named (@Fname) is created !

I change to codes as follows:

..

CREATE TABLE [dbo].[(@Fname)] (

..

Is the change correct ?

Thanks for your help.

You'll have to use dynamic SQL. Put everything into a string and concatenate the table name.

Here's an example (uncompiled, so test it):

DECLARE @mystring nvarchar(max)

SET @mystring = 'CREATE TABLE dbo.' + @Table + ' (Col1 int)'

EXEC @mystring

Sorry to tell you it can't work.... :crying:

I issue the following codes :

DECLARE @ExStr varchar(500)

SET @ExStr = 'CREATE TABLE dbo._X080805 (

[ICno] [int] NOT NULL DEFAULT (0),

[Xdate] [smalldatetime] NOT NULL

) ON [PRIMARY] '

EXEC @ExStr

================ But get the following result :

Server: Msg 203, Level 16, State 2, Line 8

The name 'CREATE TABLE dbo._X080805 (

[ICno] [int] NOT NULL DEFAULT (0),

[Xdate] [smalldatetime] NOT NULL

) ON [PRIMARY] ' is not a valid identifier.

================

An alternate suggestion is welcome and thanks a lot for your help.

You need to use EXEC (@ExStr). Otherwise SQL SERVER will expect the value of @ExStr to be a stored procedure.

That's correct... I missed that little "nuance"...

The code needs to look like this... Note the parentheses around @ExStr in the EXEC statement.

DECLARE @ExStr varchar(500)

SET @ExStr = 'CREATE TABLE dbo._X080805 (

[ICno] [int] NOT NULL DEFAULT (0),

[Xdate] [smalldatetime] NOT NULL

) ON [PRIMARY] '

EXEC (@ExStr)

Since you were trying to make the table name variable, the following will work just fine... I added the brackets just to be on the safe side if @FName turns out to be a whacky name....

DECLARE @ExStr VARCHAR(8000),

@FName VARCHAR(128)

SET @FName = '_X080805'

SET @ExStr =

' CREATE TABLE dbo.['+@FName+'] (

[ICno] INT NOT NULL DEFAULT (0),

[Xdate] SMALLDATETIME NOT NULL)'

PRINT (@ExStr) --Just showing the SQL... comment out in production

EXEC (@ExStr)
