2.3.3 MySQL
The MySQL connection is an ODBC connection. You must use the Windows
ODBC Data Source Administrator to configure the database connection.
Currently only system data sources are supported and show in the Data Source
combo box. The Login ID and Password may be optional. They will be set to
blank in the connection string. It has been found that when set to blank, the
login id and password configured in the system data source are used. You can
select the <default> database (default as configured in the data source) or
select a different database.
2.3.4 Remember and Automatically Login
If you select the Remember and Automatically Login check box, the Login
ID and Password will be remembered and the next time the application starts
an attempt will be made to login without showing the dialog again. Regardless
of whether this check box is selected, all other information (Database Type,
Data Source, etc.) will be remembered for all databases.
If you do not check the Remember and Automatically Login check box, the
username and password are still saved so the LNDB Engine can connect to the
database. However, in this case, the username and password are not
automatically filled in on the login dialog box.
