# DB Connection Class (TFloDBCon)

As the following screenshot illustrates, the **DB Connection** module accepts details of the server and database that is being accessed. A single **Statelake** configuration may have multiple DB Connections, which may all point to different servers and/or databases.

The **DB Connection** object class can be used to interact with the **DB Connection** during a mapping process, to provide access to properties of the **DB Connection** so they can be altered for this specific **Map**.

You can access the **DB Connection** object by referencing **Source.DBCons\[0].DBCon** or **Dest.DBCons\[0].DBCon**, where *source* and *dest* are pointers to the source and destination **Data Definitions** of the **Map**.

Among other things, the following tasks can be achieved by working with the **DB Connection** object -

* Access the property **DBCon.OtherParams** - this is used for storing custom configuration values. You can then access and modify these values using Source.DBCons\[0].DBCon.OtherParams.Values\['ParamName']
* Retrieve the name of the database - you can determine the name of the database you are connecting to using Dest.DBCons\[0].DBCon.Database. This is handy for storing in log messages.
* Retrieve the name of the user and their password - the name of the user you are connecting to the database can be determined by using Dest.DBCons\[0].DBCon.Username. The password can also be accessed. This is also handy for storing in log messages.

**Declaration**: Source.DBCons\[0].DBCon : TFloDBCon

Dest.DBCons\[0].DBCon : TFloDBCon
