create user table

[Gordon White]

I am building an APP, and I need to create a user table with all of their info in a table in a database.

I don't want create a user login table, I know how to do that.

For example:
I am a user and I login to this app for the first time, I will fill in my form info and hit submit. All is stored in a table just for me.

I come back a week later and re-login to modify my info.

End example:

I know how to create a login user table, but how do I reference their private table?

Thanks
