| What is the time for - the duration of the processing? i.e. from cursor open to close?Try inserting into a temp table.Then you can loop through the temp table (could use a cursor but no need).I'm guessing the dynamic sql has an effect on the cursor processing - doing this will make the processing local to the statement and also make it easy to see whether it is the extract of the data that is the issue or the processing.==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |
