Re: SQL meaning

Thanks Stephane


So the query cannot be wriiten as follows?

SELECT   userobj.ID, NAME, summary
    FROM userobj
   WHERE userobj.NAME LIKE 'A%'
     *AND attr1 IN ('#ID#TOP')*
     AND userobj.ID IN (
            SELECT ID
              FROM userattr
             WHERE ( attr1 IN (
                          SELECT ID
                            FROM orgattr
                           WHERE orgattr.attrname = 'CONTAINEDBYOBJECTGROUP'
                             AND attrval IN ('#ID#TOP'))
                   ))
ORDER BY userobj.ID



TIA

Alex
