I am developing a database API for a project, with commands for getting data from the database. For example, I have one gib table, so the command for that is:

getgib name  alias limit fields

If the user pass their name:

getgib rahul 

Then it will return all gib data whose name is like rahul. If an alias is given then it will return all the gib owned by the user whose alias (userid) was given. I want to design the commands:

• limit: to limit the record in query,
• fields: extra fields I want to add in the select query.

So now the commands are set, but:

1. I want the gibs by the gibid, so how to make this or any suggestion to improve my command is welcome.

2. If the user doesn't want to specify the name, and he wants only the gibs by providing alias, then what separator should I use instead of name?
