Hi,

Below is a script i am trying to run but the explain states a run time of approximately 104 hours ! Obviously, this is not acceptable.

The ICID_TIS_ACCOUNT and ACC_INFO tables have UPI's of ACC_no and have 2.7m and 1.6m rows respectively.

The FP_TRAFFIC_SUM table has 177m rows with a UPI spread over 11 cols and separate NUSI's of STD and TELNO, ACC_no, Country_code.

Finally the Country_code table has 223 rows and a UPI of Country_code.

Stats are only collected on the 3 NUSI's. The Export is about 2m rows.

Any ideas would help.

Thanks
