    The plan is changing because in the first querry you have used
    Code:
    AND (tptfbdr_a.codptf = 'CROSB')
    and in the next
    Code:
    AND (tptfbdr_b.codptf = 'WARTS')
    And because of this the access order of the table has changes as the table tptfbdr_b is some where at the bottom and tptfbdr_a is at the top in the from clause.

    Try using
    Code:
    AND (tptfbdr_a.codptf = 'WARTS')
    and see whats the plan.
