sql-server-2008-r2 – 获取SQL Server 2008 R2中表值函数的结果列

对于常量生成器,我喜欢获取所有表值函数的结果列的元数据(每个表值函数返回的列的名称是什么).我怎么能得到它们？我是否必须解析函数的源代码,或者是否有提供此信息的接口？

谢谢你的帮助

克里斯

我用以获取TVF的以下查询：

SELECT udf.name AS Name,SCHEMA_NAME(udf.schema_id) AS [Schema]
FROM master.sys.databases AS dtb,sys.all_objects AS udf
WHERE dtb.name = DB_NAME() 
AND (udf.type IN ('TF','FT')) 
AND SCHEMA_NAME(udf.schema_id) <> 'sys'

解决方法

此信息可在 sys.columns中获得

Returns a row for each column of an object that has columns,such as
views or tables. The following is a list of object types that have
columns:

• Table-valued assembly functions (FT)

• Inline table-valued sql functions (IF)

• Internal tables (IT)

• System tables (S)

• Table-valued sql functions (TF)

• User tables (U)

• Views (V)

SELECT *
FROM sys.columns
WHERE object_id=object_id('dbo.YourTVF')
