Sybase Stored Procedure fails to load with error 'java.lang.IllegalArgumentException: The column name is not valid'

Sybase stored procedure fails to load in TIBCO Spotfire with below error and works fine in SQL Developer:

InformationModelServiceException at Spotfire.Dxp.Services:
An Internal Error has occurred. java.lang.IllegalArgumentException: The column name is not valid. (HRESULT: 80131509)

If a Sybase stored procedure returns a column which is not named or with no alias, it fails to load in Spotfire as that column is unnamed. 

Sybase Stored procedures returning unnamed columns are not supported. Below is the example of such Stored Procedures :

CREATE PROCEDURE TestProc

AS
BEGIN
    ------
   -------
   select convert(varchar(12), L.APPROVED_DATE) from tablename;
   -------
END

In above example, stored procedure returns a column using convert() function which has no alias and is considered as unnamed column.

Add alias where ever necessary specially when functions as in above query are used and if stored procedure returns that column.
By changing the select statement as below, Sybase stored procedures will be loaded in Spotfire as well.
 

CREATE PROCEDURE TestProc

AS
BEGIN
    ------
   -------
   select convert(varchar(12), L.APPROVED_DATE) as column_name from tablename;
   -------
END
