我正面临以下问题
我使用的是Spring jdbc，数据库是SQL Server 2008 R2
我在SQL服务器中定义了一种数据类型
CREATE TYPE [dbo].[EIMREQUESTLOG] AS TABLE(
[EIMREQUESTID] [bigint] NULL,
[EIMREQUESTDETAILID] [bigint] NULL,
[REQUESTPACKET] [xml] NULL,
[REQUESTHEADER] [xml] NULL
)
和使用此数据类型的存储过程
ALTER procedure [dbo].[EIMRequestPacket_Log]
-- Add the parameters for the stored procedure here
@pEIMRequestLog DBO.EIMREQUESTLOG readonly,
@pRequestTypeId smallint = NULL,
@pIsInternal char(1) = '0'
AS
DECLARE
@vCreated datetime
BEGIN

END

但是当我调用此方法时，它会给出以下异常

我无法解决如何从java传递用户定义表类型的sql server的问题。
