今日有应用人员反映数据一直出不来,平时只需要几分种就可以跑出的数据,查看了等待事件为
enq: TT - contention
语句为insert语句,代码为- [code]INSERT INTO VGOPMK.TMK_AUDIT_FT_CLI_ACT_M ( STATIS_MONTH, PROV_ID, PROV_NAME, CITY_ID, CITY_NAME, SERV_NUMBER ) SELECT :B1 , TB.PROV_ID, TB.PROV_NAME, TB.CITY_ID, TB.CITY_NAME, TA.SERV_NUMBER FROM VGOPMK.TMK_AUDIT_FT_CLI_BEFACT_TEMP TA, VGOPDW.VDW_NUMBER_SEGMENT TB WHERE SUBSTR(TA.SERV_NUMBER,1,7) = TB.SEGMENT GROUP BY TB.PROV_ID, TB.PROV_NAME, TB.CITY_ID, TB.CITY_NAME, TA.SERV_NUMBER
复制代码 INSERT INTO VGOPMK.TMK_AUDIT_FT_CLI_ACT_M ( STATIS_MONTH, PROV_ID, PROV_NAME, CITY_ID, CITY_NAME, SERV_NUMBER ) SELECT :B1 , TB.PROV_ID, TB.PROV_NAME, TB.CITY_ID, TB.CITY_NAME, TA.SERV_NUMBER FROM VGOPMK.TMK_AUDIT_FT_CLI_BEFACT_TEMP TA, VGOPDW.VDW_NUMBER_SEGMENT TB WHERE SUBSTR(TA.SERV_NUMBER,1,7) = TB.SEGMENT GROUP BY TB.PROV_ID, TB.PROV_NAME, TB.CITY_ID, TB.CITY_NAME, TA.SERV_NUMBER [/code]
想请问下,有没有碰到这种情况的,碰到这种情况应该如何分析?,enq: TT - contention,看了下刘大BLOG的文章,没太懂,请指教 |
