Here’s just a short post to feed the search engine gerbils. لعبة لربح المال So today, I created a stored procedure that accepted a list of ID’s and filtered them. The most efficient way to handle this was using table-valued parameters (TVPs). خدمة عملاء كونكر عربى My code looks similiar to this:
USE AdventureWorks2012;
GO
/* Create our new table type */
IF NOT EXISTS(SELECT * FROM sys.types WHERE name = 'CustomerList')
BEGIN
CREATE TYPE dbo.CustomerList AS TABLE
(
CustomerID INT
, ID INT
);
END;
IF OBJECTPROPERTY(OBJECT_ID('dbo.CustomerTerritoryFilterGet_sp')
, N'IsProcedure') IS NOT NULL
DROP PROCEDURE dbo.CustomerTerritoryFilterGet_sp;
GO
/* Create a proc to test with */
CREATE PROCEDURE dbo.CustomerTerritoryFilterGet_sp
@Customers CustomerList READONLY
, @TerritoryFilter INT
AS
BEGIN
SELECT DISTINCT sc.CustomerID, c.ID
FROM Sales.Customer AS sc
JOIN @Customers AS c
ON sc.CustomerID = c.CustomerID
WHERE sc.TerritoryID = @TerritoryFilter;
RETURN 0;
END
GO
/* Test our stored procedure */
DECLARE @myList CustomerList;
INSERT INTO @myList
VALUES (1, 10), (2, 20), (3, 30), (4, 40), (5, 50), (6, 60), (7, 70);
EXECUTE dbo.CustomerTerritoryFilterGet_sp
@Customers = @myList
, @TerritoryFilter = 1;
GO
GRANT EXECUTE ON dbo.CustomerTerritoryFilterGet_sp To myApp;
GO
This would typically be sufficient for most stored procedures. However, my app dev was getting the following error:
The EXECUTE permission was denied on the object 'customerList', database 'AdventureWorks2012', schema 'dbo'.
Wait, we need to explicitly grant permissions to the new data type? Okay, that’s easy enough… let’s just run a quick GRANT statement:
GRANT EXECUTE ON dbo.CustomerList To myApp;
Msg 15151, Level 16, State 1, Line 1 Cannot find the object 'CustomerList', because it does not exist or you do not have permission.
Okay, now I’m confused… what am I missing? It turns out, you need to use a slightly different syntax to grant permissions to a new data type. baloot This syntax, which explicitly tells SQL Server that we’re granting permissions on a Type class, works just fine:
GRANT EXECUTE ON TYPE::dbo.CustomerList To myApp; /* Time to clean up! */ -- DROP PROC dbo.CustomerTerritoryFilterGet_sp; -- DROP TYPE dbo.CustomerList;
Command(s) completed successfully.
