Every user of a database has a user ID. UltraLite supports up to four user ID/password combinations.
UltraLite user IDs are separate from MobiLink user names and from other SQL Anywhere user IDs. You cannot change a user ID
once it is created. Instead, you must delete the user ID and then add a new one.
You cannot set the UID to NULL or an empty string. The maximum length for a user ID is 31 characters. User IDs are case insensitive.
Any leading or trailing spaces in parameter values are ignored. This connection parameter's value cannot include leading single
quotes, leading double quotes, or semicolons.
