I've got a task that's gonna require me to compare one table to another
and remove the rows from the first table that are found in the second
table that match email_address.
I'm running 4.0.20a-nt-log. The first table has 10 colomns and about 50K
records, and the second table has 46 columns and has about 16K records.
I've attempted a number of selects that just sat and hung the computer.
I know I must be doing something wrong. I figure I'll need to do a left
join on it, but I've not had much experience with joins as such and I
need a little assistance.
Can anyone help me work this out? If you need more info, let me know.
Ed
