SDO_Relate and SDO_filter with SDO_Join

Question

Hi all,
Could someone please help me in finding the difference with the below query
I am comparing SDO_Relate and SDO_filter with SDO_join.
Query using SDO_Relate and SDO_filter
SELECT count(spa1.id)
FROM temp_tab tmp_tab,
spatial_tab spa1,
spatial_tab spa2
WHERE tmp_tab.id = spa1.id
AND sdo_filter (spa2.geo_link, spa1.geo_link) = 'TRUE'
AND spa1.rowid != spa2.rowid
AND sdo_geom.relate (spa1.geo_link, 'ANYINTERACT', spa2.link, .0000005) = 'TRUE'
With this I get a output of 600 rows.
Query using SDO_join
SELECT count(spa1.id)
FROM spatial_tab a, spatial_tab b, temp_tab d,
TABLE(SDO_JOIN('spatial_tab', 'geo_link', 'spatial_tab', 'geo_link',
'mask=ANYINTERACT')) c
WHERE (c.rowid1 = a.rowid AND c.rowid2 = b.rowid)
and (d.id = a.id);
With this I get a output of 750 rows.
I assume that both the query should return 600 rows.
rgds and thanks

Can you please try:
SELECT count(spa1.id)
FROM spatial_tab a, spatial_tab b, temp_tab d,
TABLE(SDO_JOIN('spatial_tab', 'geo_link', 'spatial_tab', 'geo_link',
'mask=ANYINTERACT')) c
WHERE (c.rowid1 = a.rowid AND c.rowid2 = b.rowid)
and (d.id = a.id) and c.rowid1 != c.rowid2;
