sql-server-2005 – 如何在SQL Server 2005中查找视图的派生列类型？

例如,假设我有一个视图：

CREATE VIEW [dbo].[PaymentSchedule_vw]
AS
    SELECT
         [Order].Id                [Order Id],[PaymentSchedule].Date    [Payment Date]
    FROM
        _Order123 [Order]
        INNER JOIN
            _Order123_Shedule [PaymentSchedule]
            ON
            [Order].Id = [PaymentSchedule].OrderId

GO

如何发现[订单ID]和[付款日期]的类型？

解决方法

SELECT c.name,t.name,c.max_length,c.precision,c.scale
FROM   sys.columns c
       JOIN sys.types t
         ON t.user_type_id = c.user_type_id
            AND t.system_type_id = c.system_type_id
WHERE  object_id = OBJECT_ID('PaymentSchedule_vw')

或者您可以使用sql_VARIANT_PROPERTY – some examples here.
