This setting is created and maintained by Dexterity if the SQLUser setting isn't included in the defaults file.
SQLLastUser = user_ID
• user_ID - The user ID of the most recent user to connect to a data source using the current computer.
This setting is created and used only if the SQLUser setting isn’t already defined in the defaults file. It's used to provide a default value for the User ID field in Dexterity’s predefined SQL Login window. This setting is updated every time a different user connects to a data source using the current computer.
The SQLLastUser setting won’t affect a login window you create for use with your application unless you use Defaults_Read() and the set statement to make this setting’s value appear as the default value for the user ID field.
