Lets say I have two MySQL databases with some complex table structures. Neither database has the same table name. Lets say these tables contain no rows (they do but I could truncate the tables, the data is not important right now, just testing stuff). Lets say I need these 2 databases merged into one. For instance:

DB1:

cities
states

DB2:

index
subindex
posts

I want to end up with a single DB that contains:

cities
states
index
subindex
posts

Is this possible?

    You can use RENAME TABLE on all the tables from one of the databases.

    See: http://dev.mysql.com/doc/refman/5.0/en/rename-table.html

    RENAME TABLE current_db.tbl_name TO other_db.tbl_name;

    Providing there are no duplicates.
