When you create a database connection, Dreamweaver stores the connection information in an include file in the Connections subfolder in the sites local root folder. You can edit or delete the connection information in the file manually or as follows.
A list of connections appears in the panel.
The dialog box you used to create the connection appears.
Dreamweaver automatically updates the include file, which updates all the pages in the site that use the connection.
If you rename a connection, you should update every recordset that uses the old connection name by double-clicking the recordset in the Bindings panel and choosing the new connection name in the Recordset dialog box.
