我有一个SP prc_Foo_Delete具有以下签名:
ALTER PROCEDURE [prc_Foo_Delete] @fooIds [int_udtt] READONLY,@deleteReason int,@comment nvarchar(512),@deletedBy nvarchar(128)
int_udtt定义为:
CREATE TYPE [int_udtt] AS TABLE( [Id] [int] NOT NULL,PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (IGNORE_DUP_KEY = OFF) )
我试图在Management Studio中使用以下脚本调用此SP:
DECLARE @return_value int EXEC @return_value = [prc_Foo_Delete] @fooIds = 3,@deleteReason = 2,@comment = N'asfdasdf',@deletedBy = N'asdfa' SELECT 'Return Value' = @return_value GO
我得到的错误是:操作数类型冲突:int与int_udtt不兼容.如何传递int或int列表来调用此工具(我知道如何在代码中执行,但不在Management Studio中).
解决方法
由于您已将用户定义的类型定义为存储过程的参数,因此在调用存储过程时也需要使用该用户定义的类型!你不能只发一个INT而不是….
尝试这样的东西:
-- define an instance of your user-defined table type DECLARE @IDs [int_udtt] -- fill some values into that table INSERT INTO @IDs VALUES(3),(5),(17),(42) -- call your stored proc DECLARE @return_value int EXEC @return_value = [prc_Foo_Delete] @fooIds = @IDs,-- pass in that UDT table type here! @deleteReason = 2,@deletedBy = N'asdfa' SELECT 'Return Value' = @return_value GO
