>>I am having a problem with the SQL Update below. From the amount of time it takes to run with only 1 or 2 records in the cursor c_chng I believe it is ignoring the index on k_ivinvt and scanning all 186K recs in the inventory table IVINVT. The last time I had this problem was on updating invoice lines and I fixed it by adding a 2nd line to the where clause to include the invoice key. This time there is no other index I can use. The two tables are tied only by the ivinvt.k_ivinvt = c_chng.k_ivinvt. This has got to be a really common event so I know I am missing something here.

Borislav,
Allocated is a numberic 7,2 that holds the number if inventory items on sales orders that have not been invoiced.
The result of SYS(3054)is:
&mSqlCommand
Rushmore optimization level for intermediate result: none
Rushmore optimization level for table ivinvt: none
Joining table ivinvt and intermediate result using temp index
Good suggestion but I don't know why it is not using Rushmore.
Thanks for the help.
