Table-valued function refresh

问题

I have a table-valued function (TVF) in SQL Server that looks like this:

CREATE FUNCTION TVF_xyz(@AuditKey INT)
RETURNS TABLE
AS
    RETURN
        SELECT *
        FROM xyz 
        WHERE AUDIT_KEY = @AuditKey
GO

Now, I added a new column to the xyz table.

When I query using TVF_xyz, it doesn't show me the new column (shows all other columns except newly added).

Query:

SELECT TOP 10 * 
FROM TVF_xyz (1543)

I would like to know, how to refresh TVF to show new column.

PS: Select * used in TVF to fetch all columns.

回答1:

After bit of searching, I found sp_refreshsqlmodule (Transact-SQL), its common behavior of TVF.

In order to refresh TVF, following SP needs to be executed:

EXEC sys.sp_refreshsqlmodule 'TVF_xyz'

The following SQL function explicitly states that it returns a TABLE. Therefore, the returned rowset structure is implicitly defined.

sample

CREATE FUNCTION ProductsCostingMoreThan(@cost money)  
RETURNS TABLE  
AS  
RETURN  
    SELECT ProductID, UnitPrice  
    FROM Products  
    WHERE UnitPrice > @cost
