Re: move tables into different database
You could do that if you don't mind moving the data (which may be expensive depending on how much data you have). Also if your table is partitioned, you may have to do another additional step (to recover partitions).

If you are on hdfs

How about--

use db1;
create table table1 like db2.table1;

and move the data?

Thanks,

AFAIK there is no way in HiveQL to do this. We had a similar requirement in the past, and we wrote a shell script to update the MySQL metastore directly (obviously not the cleanest or recommended way to go).
