## Open an existent database

### Description

Open a database connection from a virtual connection.

### Usage

    ## S4 method for signature 'aRTconn':
    openDb(object, dbname, update, views)

### Arguments

`object` | Object of class `aRTconn`.
`dbname` | Database name.
`update` | When the database version is older than the actual TerraLib version, set it `TRUE` to update to the newest version. You can connect to a database older than the actual version without updating it, but you have to take into account that unexpected errors may occour.
`views` | A string with a username. If used, aRT will load the views from that user instead of the views of the owner of the connection. Note that the permissions in the database are controlled by the user/password of the aRTconn, that still being used for the connection. This user is just for TerraLib purposes.
