Calling Scalar-valued Functions in SQL

Question

I have migrated a database from oracle, and now have a few Scalar-valued Functions.

However, when I call them, I get an error saying:

Cannot find either column "dbo" or the user-defined function or aggregate "dbo.chk_mgr", or the name is ambiguous.

I'm calling it like this:

SELECT dbo.chk_mgr('asdf')

What am I doing wrong?

Answer 1

Are you sure it's not a Table-Valued Function?

The reason I ask:

CREATE FUNCTION dbo.chk_mgr(@mgr VARCHAR(50)) 
RETURNS @mgr_table TABLE (mgr_name VARCHAR(50))
AS
BEGIN 
  INSERT @mgr_table (mgr_name) VALUES ('pointy haired boss') 
  RETURN
END 
GO

SELECT dbo.chk_mgr('asdf')
GO

Result:

Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function 
or aggregate "dbo.chk_mgr", or the name is ambiguous.

However...

SELECT * FROM dbo.chk_mgr('asdf') 

mgr_name
