Hi Sergey,

this is the problem,

i need to build, before the effective select, a pivot structured table in order to force the select to construct a result with the correct fields.

I need build a array(nFields,3) for fields,

and uses

CREATE CURSOR resultSchema FROM ARRAY ArrayName

and

only now I can execute one tricked select :
SELECT * FROM resultSchema
UNION ALL
mySelect

You he seems acceptable ?
