Hi List,

The below query is taking a long time to execute from the Java application and when doing a record count from TOAD. Is there any way I can rewrite the below query?

SELECT

  A0.ID ID0,
  A0.SEG_GRP GRP0,
  A1.ID ID1,
  A1.SEG_GRP GRP1,
  A2.ID ID2,
  A2.SEG_GRP GRP2,
  A3.ID ID3,
  A3.SEG_GRP GRP3

FROM

  ROUTE_BUILD A0,
  ROUTE_BUILD A1,
  ROUTE_BUILD A2,
  ROUTE_BUILD A3

WHERE

  A0.REQUEST_ID=1943 AND
  A1.REQUEST_ID = 1943 AND
  A2.REQUEST_ID = 1943 AND
  A3.REQUEST_ID = 1943 AND

(NVL(A0.SEG_TOA + (( SELECT TRANSFER_TIME FROM AIRLINE_TRANSFER_TIME WHERE
STN_KEY=A1.ORG_KEY AND
  FROM_AIRLINE_KEY=A0.AIRLINE_KEY AND
  TO_AIRLINE_KEY=A1.AIRLINE_KEY AND
  SERVICE_KEY=1)/(24*60)),A0.SEG_TOA) < A1.SEG_LAT) and   A0.SEG_GRP = A1.SEG_GRP-1 AND
(NVL(A1.SEG_TOA +(( SELECT TRANSFER_TIME FROM AIRLINE_TRANSFER_TIME WHERE
STN_KEY=A2.ORG_KEY AND
  FROM_AIRLINE_KEY=A1.AIRLINE_KEY AND
  TO_AIRLINE_KEY=A2.AIRLINE_KEY AND
  SERVICE_KEY=1)/(24*60)),A1.SEG_TOA) < A2.SEG_LAT) AND   A1.SEG_GRP = A2.SEG_GRP-1 AND
(NVL(A2.SEG_TOA +(( SELECT TRANSFER_TIME FROM AIRLINE_TRANSFER_TIME WHERE
STN_KEY=A3.ORG_KEY AND
  FROM_AIRLINE_KEY=A2.AIRLINE_KEY AND
  TO_AIRLINE_KEY=A3.AIRLINE_KEY AND
  SERVICE_KEY=1)/(24*60)),A2.SEG_TOA) < A3.SEG_LAT) AND   A2.SEG_GRP = A3.SEG_GRP-1 Any help in this regard is very much appreciated.

Thanks and Regards,
