Copy one column from one database to another
I need to copy the content from a column in one database into the matching column in another, so that the same content goes in the record with the same ID. Something like the following pseudo stuff:

    SET database2.table1.columnA TO database1.table1.columnA WHERE database2.id = database1.id
