How to turn subquery into JOIN?

 

Current long running query:

 

 

UPDATE /*+ full(b) parallel(b,8) */ SRV B SET SRV_STS_CD =

'CE' WHERE PARTITION_ID = 8 AND (SRV_STS_CD = 'CS' OR SRV_STS_CD =

'HA') AND SYS_CREATION_DATE > SYSDATE - 730 AND SRV_TRX_S_NO IN (SELECT

SRV_TRX_S_NO FROM DVC WHERE PARTITION_ID = 8 AND

DVC_TRX_STS_CD != 'CS');

 

 

Modified query:

 

UPDATE /*+ full(b) parallel(b,4) use_hash(DVC) leading(DVC_) unnest */ SRV B SET SRV_STS_CD =

'CE' WHERE PARTITION_ID = 8 AND (SRV_STS_CD = 'CS' OR SRV_STS_CD =

'HA') AND SYS_CREATION_DATE > SYSDATE - 730 AND SRV_TRX_S_NO IN (SELECT /*+ use_hash(DVC) full(DVC) parallel(DVC,4) */

SRV_TRX_S_NO FROM DVC_TRX_REPOS WHERE PARTITION_ID = 8 AND

DVC_TRX_STS_CD != 'CS')

;
