# Litedao

 Intuitive interaction with SQLite database 

This project is part of the [Pyrustic Ecosystem](https://pyrustic.github.io).

[Installation](#installation) | [Reference](https://github.com/pyrustic/litedao/tree/master/docs/reference#readme) | [Shared](https://github.com/pyrustic/shared)

## Overview

Here is an example of an interaction with an SQL database:

```python

from litedao import Litedao

# Database path (if this file does not exist, it will be created)

DATABASE_PATH = "/home/alex/litedao_test.db"

# SQL code to initialize the database

INIT_SCRIPT = """\

CREATE TABLE friend (username TEXT PRIMARY KEY, email TEXT NOT NULL);

CREATE TABLE enemy (username TEXT PRIMARY KEY, email TEXT NOT NULL)"""

# Insertion SQL code

INSERTION_SQL = """\

INSERT INTO friend (username, email)

VALUES (?, ?), (?, ?)"""

# Selection SQL code

SELECTION_SQL = "SELECT * from friend"

def insert_data(litedao):

    # inserts data in the database then returns a boolean

    return litedao.edit(INSERTION_SQL, param=("alex", "[email protected]",

                                       "rustic", "[email protected]"))

def select_data(litedao):

    # returns the selection

    return litedao.query(SELECTION_SQL)

# litedao instance

litedao = Litedao(DATABASE_PATH, init_script=INIT_SCRIPT)

# insert data if this database is newly created

if litedao.is_new:

    insert_data(litedao)

selection = select_data(litedao)

tables = litedao.tables()

columns = litedao.columns("friend")

litedao.close()  # if you forget to close Litedao, it will close itself at exit

print(selection)

# output: (['username', 'email'], [('alex', '[email protected]'), ('rustic', '[email protected]')])

print(tables)

# output: ['friend', 'enemy']

print(columns)

# output: [(0, 'username', 'TEXT', 0, None, 1), (1, 'email', 'TEXT', 1, None, 0)]

```
