Is there a way to use this method, while also getting data from a MSSQL table, and inserting or updating MySQL ?? I'm guessing not.

I have another situation that does:

insert into MySQL_Stage...wp_users

select fld1, fld2,fld3

from MSSQL_Database..MyTable

I could do the SELECT into variables, then run similar code to what you suggested above.

Edit: That's what I did, which works.
