In that case you would need to BEGIN IMMEDIATE or BEGIN EXCLUSIVE and perform all your actions within the same thread.

Good to know about the "create table as" syntax, but I'm not selecting rows and just copying to another table. For each row in one sqlite table, the system under development may do may do many things down stream - send emails, query other databases, and create tables and insert into the temporary sqlite database. Right now I have a option to load all rows into memory to remove the lock so tables can be created downstream.
