I'm working on a reporting module for a company project. Although we use an ORM for our application, I've decided to write stored procedures for the reports in anticipation of migrating to SSRS.
These stored procedures require table-valued parameter input. As such, I've created my table type:
USE MyDatabase
GO
/****** Object: UserDefinedTableType [dbo].[IntList] Script Date: 5/8/2013 5:20:59 PM ******/
CREATE TYPE [dbo].[IntList] AS TABLE(
[Id] [int] NOT NULL,
PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (IGNORE_DUP_KEY = OFF)
)
GO
I have the following SQL Server stored proc:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
USE MyDatabase
GO
-- =============================================
-- Author: <lunchmeat317>
-- Create date: <05/06/2013>
-- Description: <File Type Report>
-- =============================================
ALTER PROCEDURE Report_FileType
@filetype varchar(20) = null,
@User intList READONLY,
@Group intList READONLY
AS
BEGIN
SET NOCOUNT ON;
/*
lf = LibraryFile
lfu = LibraryFileAssignedUser
lfg = LibraryFileAssignedGroup
*/
SELECT Extension AS FileType, COUNT(1) AS TotalFiles
FROM LibraryFile lf
LEFT JOIN LibraryFileAssignedUser lfu
ON (SELECT COUNT(1) FROM @User) != 0
AND lfu.LibraryFileId = lf.Id
LEFT JOIN LibraryFileAssignedGroup lfg
ON (SELECT COUNT(1) FROM @Group) != 0
AND lfg.LibraryFileId = lf.Id
WHERE ((@filetype IS NULL) OR (Extension = @filetype))
AND (
((@User IS NULL) OR (lfu.UserId IN (SELECT * FROM @User)))
OR ((@Group IS NULL) OR (lfg.HubGroupId IN (SELECT * FROM @Group)))
)
GROUP BY Extension
END
GO
When I attempt to alter the stored procedure, I continually get the error message
Msg 137, Level 16, State 1, Procedure Report_FileType
Must declare the scalar variable "@User".
Msg 137, Level 16, State 1, Procedure Report_FileType
Must declare the scalar variable "@Group".
I can't figure out why this is happening. If I do use a scalar type (and update my code to match) it works. However, when I try to use a TVP, I can't compile the stored procedure.
For what it's worth, I've added the type, but I haven't set the permission on it yet. However, I don't expect that would cause a compilation error; it would only cause an error at runtime (which I've dealt with before).
Does anyone have any experience with this issue? Thanks!
Interesting, I haven't used this before, but it seems that you cannot test for @User / @Group IS NULL since it is a table.
