[sqlite] Updating a filed in table a with contents from table b

I have a large table with ~350k records for which I'm in the process of standardising data. The fields I'm most interested in standardising are albumartist, artist, performer and composer. I'm dealing with one at a time and the logic for each is the same. I'll state in advance that I'm a SQL

[sqlite] Question regarding use of REPLACE
