存储过程中的表类型参数导致操作数类型冲突错误

Question

我想给一个标识符数组作为存储过程的参数.

存储过程如下所示:

ALTER PROCEDURE [dbo].[SearchPerson]
    @personType INT = NULL,
    @city NVARCHAR(64) = NULL,
    @siteIds IntegerList READONLY,
    -- 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...
    )

用户表类型如下所示:

CREATE TYPE [dbo].[IntegerList] AS TABLE(
    [Value] [int] NULL
)

当我从SSMS中的脚本调用存储过程时(我最初从.NET代码调用它时遇到同样的问题):

DECLARE @siteIds AS IntegerList,
@personType AS INT = 1
INSERT INTO @siteIds VALUES (1)
EXEC [dbo].[SearchPerson] @personType, @siteIds

我收到了错误:

操作数类型碰撞:int与IntegerList不兼容

我找到了答案:这是表类型参数的顺序导致错误!

表类型参数必须是存储过程参数中的第一个参数,并且在传递给存储过程调用的参数中也是ALSO!

存储过程:

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...
    )

电话:

DECLARE @siteIds AS IntegerList,
@personType AS INT = 1
INSERT INTO @siteIds VALUES (1)
EXEC [dbo].[SearchPerson] @siteIds, @personType -- PUT @siteIds FIRST !

一个sql server bug或者我错过了什么？
