sqlite3 gui


N

NighterNet

This took a while to get a gui working. I am new at this coding.

This work with sqlite3 Python Version: 3.1.0. The older version
doesn't work.

#!/usr/local/bin/python
'''
This is for basic database access to view the information.
Python version: 3.1.0

Features:
-view database.
-run script
-update row
-delete row
-insert row

To do list:
-delete table
-create table
-export database
-import database
-primary id need to able to insert to the table
-delete table row
-refresh data

Note:
-It doesn't remove the GUI
-It bit buggy.
-Python version: 3.0.1 -Doesn't support the gui

execute script without '"' -> INSERT INTO member (user, password)
VALUES( "admin", "admin")

Not sure what you guys think about this. Still working on it. I can't
hard code this well. Still learning it. >.<
