I'm looking into that at the moment.
I'm getting some very variable results.
There are some tables that it is easy to do this for.
However for some tables, I don't get data in the right format, so I need to
perform some queries to get the right values to use when populating.
In this situation I'm not sure if I should drop the indexes to make make the insert faster,
or keep them to make the selects faster.
Thanks
