Search Sqlite Database - All Tables and Columns

Question

Is there a library or open source utility available to search all the tables and columns of an Sqlite database? The only input would be the name of the sqlite DB file.

Answer 1

You could use "SELECT name FROM sqlite_master WHERE type='table'" to find out the names of the tables in the database. From there it is easy to SELECT all rows of each table.

For example:

import sqlite3
import os

filename = ...
with sqlite3.connect(filename) as conn:
    conn.row_factory = sqlite3.Row
    cursor = conn.cursor()    
    cursor.execute("SELECT name FROM sqlite_master WHERE type='table'")
    for tablerow in cursor.fetchall():
        table = tablerow[0]
        cursor.execute("SELECT * FROM {t}".format(t = table))
        for row in cursor:
            for field in row.keys():
                print(table, field, row[field])

I know this is late to the party, but I had a similar issue but since it was inside of a docker image I had no access to python, so I solved it like so:

for X in $(sqlite3 database.db .tables) ; do sqlite3 database.db "SELECT * FROM $X;" | grep >/dev/null 'STRING I WANT' && echo $X; done

This will iterate through all tables in a database file and perform a select all operation which I then grep for the string. If it finds the string, it prints the table, and from there I can simply use sqlite3 to find out how it was used.

Figured it might be helpful to other who cannot use python.

@MrWorf's answer didn't work for my sqlite file (an .exb file from Evernote) but this similar method worked:

• Open the file with DB Browser for SQLite sqlitebrowser mynotes.exb
• File / Export to SQL file (will create mynotes.exb.sql)
• grep 'STRING I WANT" mynotes.exb.sql
