Update from Module"Countires" to Contacts (Accounts).

I have a 254 records of all the countries in the world, with fields like Countryname,Currency, some 10 fields in total etc etc.

I make a link (in SQL) to my LOCAL SuiteCRM 7.4 with Contacts.BillingCountry = Countries.Countryname ( i do this with External ODBC in MSaccess)
and then "update to " etc.

It works for one/two (to be updated fields in Contacts) but, ONLY if I update per one Countryname ,as filter, to limit the update.

The Contact records are some 58.000 and that is apparently to ““Big To Handle””

Is there an other way to do this in a simple way ?

Thanks.
William.

Maybe if you share your SQL it’s easier to understand what you’re triyng to achieve…
