Why does update take forever. When QOBDC executes an UPDATE sql statement it takes 4-5 minutes for the UPDATE statement to complete.
How do I speed this and make run faster. |

This depends on your WHERE clause used in your UPDATE statement. When you run an UPDATE command, a SELECT is run to find qualified records, when one is found, then the record is re-qualified, the specified edit fields are changed, then we move to the next record. Each QODBC table has jump-ins which act like indexes. Jump-ins allow us to ask QuickBooks for the specific data IDs we are going to update instead of scanning large XML data streams.
For example:
update InvoiceLine set InvoiceLineRate=200 where TxnID='C38-1080104832' and TxnLineID = '7133-1197736106'
in this UPDATE the TxnID is a jump-in seen when you run:
sp_columns InvoiceLine
