try them seperate:
try:
SELECT 'X'
FROM table_bus_org cu, table_site eu, table_site_part su
WHERE su.site_part2site = eu.objid
AND eu.x_site2customer = cu.objid
AND cu.x_bus_org2billcycle BETWEEN 268442453 AND 268442456
then try:
SELECT 'X'
FROM table_bus_org cu, table_site eu, table_site_part su
WHERE su.site_part2site = eu.objid
AND eu.x_site2customer = cu.objid
AND cu.x_bus_org2billcycle = 268451297)
Then:
SELECT 'X'
FROM table_x_csr_offer_cfg ofr2,
table_site_part su,
table_site_part svc,
table_x_tariff_detail td
WHERE svc.site_part2part_info =
ofr2.x_csr_offer_cfg2service
AND ofr2.x_tariff_sensitive = 1
AND su.objid = td.x_tarif_detail2site_part
AND td.x_active = 1
AND ofr2.x_csr_offer_cfg2tariff =
td.x_tariff_detail2tariff
AND ofr2.x_tariff_sensitive = td.x_active)

And so on. It looks easy to split your query. I usually split a query when it is very dificult to make sure I get the correct response.
