Question

For now I am trying to use python for sqlite3. My question is, I don’t know how to read the existed ‘abc.db’ with python.
I mean that I just know the abc.db is a sqlite3 file. But I don’t know the structure of it, and I also need to get the information from this abc.db.

I used :

import sqlite3
try:  
        sqlite_conn = sqlite3.connect('abc')  
except sqlite3.Error, e:  
         print 'conntect sqlite database failed.'  
         sqlite_logger.error("conntect sqlite database failed, ret = %s" % e.args[0]) 

So, what can I do next? I need to read the abc, and if it is possible, I want to output the content directly on the terminal. Is it possible? Because I need to analyse the data in this file. Thanks a lot!!!!

In your sqlite_conn object you could run the following command

cur = sqlite_conn.cursor()

cur.execute("SELECT name FROM sqlite_master WHERE type='table'")

    rows = cur.fetchall()

    for row in rows:
        print row[0]

Then you could do a SELECT * from <Tablename> for each of those tables. The sqlite_master is a sqlite metadata here.
