Question

For a constants generator I like to get the meta data of result columns for all my table valued functions (what are the names of the columns returned by each table valued function). How can I get them? Do I have to parse the function’s source code or is there an interface providing this information?

Thanks for your help

The following query I use to get the TVFs:

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'

Answer 1

This information is available in sys.columns

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')
