UltraLite administration tools follow a specific order of connection parameter precedence:
Device-specific options take precedence over nonspecific options. For example: device:DBF takes precedence over DBF on Windows Mobile devices.
Desktop-specific options take precedence over nonspecific options. For example: desktop:DBF takes precedence over DBF on Windows.
If you supply duplicate parameters in a connection string, the last one supplied is used. All others are ignored.
Parameters in the connection string take precedence over those supplied in the ULSQLCONNECT environment variable or a connection object.
If no value is supplied for both UID and PWD in either the connection string or ULSQLCONNECT, the defaults of UID=DBA and PWD=sql are assumed.
