I have 2 tables, table1 and table2.
I have a row in table1 and want to move it to table2 and remove it from table1. Basically, a cut+paste.
I am using php.
Just make it one table and make a flag field to determine if record is moderated or not.
So, the only thing you will need is just simple update query.
That's the way such things being done in general.
