I found the answer : it was the order of the table type parameter that caused the error !
The table type parameter must be the first in the stored procedure parameters AND ALSO in the arguments passed to the stored procedure call !
The stored procedure :
ALTER PROCEDURE [dbo].[SearchPerson]
@siteIds IntegerList READONLY, -- THIS PARAMETER HAS TO BE THE FIRST !
@personType INT = NULL,
@city NVARCHAR(64) = NULL,
-- some other params...
AS
SELECT
-- some fields...
FROM dbo.PersonView AS pv
WHERE
(
(@personType IS NULL OR pv.PersonType = @personType) AND
(@city IS NULL OR pv.City LIKE '%' + @city + '%') AND
(pv.SiteId in (SELECT si.Value FROM @siteIds AS si)) AND
-- some other params filter...
)
And the call :
DECLARE @siteIds AS IntegerList,
@personType AS INT = 1
INSERT INTO @siteIds VALUES (1)
EXEC [dbo].[SearchPerson] @siteIds, @personType -- PUT @siteIds FIRST !
A sql server bug or am I missing something ?
