Joan,

it seems the excerpt you posted is incomplete (I cannot understand that the last op is the hash join with id=13 on both plans)

please, ¿would you mind to post a tkprof-processed plan of both (without running the "explain= " param of tkprof), just to compare why the diff in rowcounts?

STAT #2 id=13 cnt=8538 pid=2 pos=2 obj=0 op='HASH JOIN (cr=217257 pr=23078 pw=4941 time=41906027 us)'

STAT #1 id=13 cnt=0 pid=2 pos=2 obj=0 op='HASH JOIN (cr=0 pr=0 pw=0 time=0 us)'
