Connecting to a database

When you click the Query Database command in the Database menu for the first time in a session (and when no database connection exists), the Connect to a Data Source dialog (screenshot below) pops up to enable you to connect to a database. To make connections subsequently, click the Quick Connect icon ic_quickconnect in the Database Query window. If connections already exist, you can select the required connection from among these.




How to connect to a database via the Connect to a Data Source dialog is described in the section Connecting to a Data Source.
