Effortlessly access your SQL servers and procedures, plus some other utilities.

Install

$ pip install loaf

Examples

Importing Into Your Project

from loaf import Loaf

Setting Up Credentials

# Setup your credentials with a single line.
loaf = Loaf(port=6969, db="pizzeria")
# Or load your credentials from a file.
loaf = Loaf(file="creds.ini")
# Or use a local SQLite file instead.
loaf = Loaf(file="pizzeria.db")

Executing Queries

# Make queries easily.
toppings = loaf.query("SELECT * from toppings")
# Load your quieries directly from files.
clients = loaf.query(file="getHappyClients.sql")
# Prevent disasters by executing multiple queries.
pepperoni_id, client_name = loaf.multi([
    "SELECT id FROM toppings WHERE name='Pepperoni'",
    "SELECT name FROM clients WHERE id=6"
])

Printing

# Display info using built-in tables!
loaf.print(pepperoni_id)
loaf.print(client_name)
loaf.print(toppings)

Data Manipulation

# Manipulate your data with dictionaries, as God intended.
for topping in toppings:
    print(topping['name'])

Pepperoni
Mushrooms
Onions

Utilities

# Not lazy enough? Try some of the pre-built queires.
# Equivalent of: SELECT name FROM client WHERE name='Marco' LIMIT 1
result = loaf.select("name", "clients", "name='Marco'", limit=1)
# Get all values from a table.
result = loaf.all("toppings")
# Got stored procedures? No problemo!
result = loaf.call("ProcedureFindClient", 1)

⚠️ Syntax for the package has changed heavily since version 0.2.0, if your project depends on Loaf and is using an inferior version, I heavily suggest that you use the previous stable version:

$ pip install loaf==0.1.30
