Error creating derived table !!!

Hie Guys,

I needed some help regarding my issue creating derived tables in the Universe Design Tool 4.0. When I click on "check syntax" while creating the derived table, I am getting the following error message - "Each calculated column must have an explicit name". The query works fine in Crystal Reports. I've attached the SQL query below. Is it because there is no comma after "ti.issue_id" at the end of the SELECT statement? If so, how did it work in crystal reports? Could anyone tell me what is wrong with the SQl? Thanks.

SELECT DISTINCT

tc.category_descr as cosa,

tcv_project.custom_value  AS project_id,

ti.issue_title as project_name,

tcv_sponsor.custom_value  AS exec_sponsor,

tis.own_employee_nbr AS bmpe_name,

DATE_FORMAT(tis_start.step_dt, ‘%m/%d/%Y’) AS start_dt,

tcv_end_dt.custom_value AS end_dt,

ts.step_descr AS current_phase,

CONCAT(‘(‘,DATE_FORMAT(ta.insert_dt, ‘%m/%d/%Y’),’) - ‘,ta.append_txt) AS status_descr

tcv_benefits.custom_value AS benefits,

tcfo.option_descr AS benefits_type,

Since the Sql works in crystal reports or can be run directly on your database,  I think the issue would be something minor.  Such as using the qualified domain names in your derived table.

a simple way to check from the universe layer, is to create a new test derived table and select the objects from the underlying tables  Just a few not the whole sql.

As you see how the sql is generated, with correct format expected by the universe designer.

You can adapt your query as necessary format.

It's difficult to reproduce the query with the database tables as there are many joins and aliases in the SQL which is difficult for me to figure out. I ran the SQL in Squirrel SQL and IDT. It runs fins. The problem is running it in UDT. My guess is this line of code - IFNULL(tcv_print.custom_value,0). If I remove it however, I get an error. Thanks.
