Answer 1

If you want to simply copy rows from a source database to a target database, something like this should work, assuming the databases are on the same server, which you said they were:

Insert Into TargetDatabase.SchemaName.TableName (TargetColumn)
Select SouorceColumn
From SourceDatabase.SchemaName.TableName

If you want to synchronize rows (eg, update or delete rows based on some criteria) between two tables in two different databases, this is far more complex. I would suggest a tool like Red-Gate Data Compare, or maybe some freeware app that does this. If you are using SQL Server 2008, the MERGE statement might work for you as well.

Answer 2

If you are looking to sync the data vs doing a simple insert I highly recommend using the tools from http://www.red-gate.com/ . Specifically sql data compare.
