pyeasysql 5.0.0

SQL Database management without even a SQL line

EasySQL - Now with Async System by 5.0.0

This library allow you to run SQL Databases without knowing even SQL.
This library will create SQL queries and execute them as you request and is very simple to use.

This library is still under development, so we appreciate if you help us improve it on the GitHub!

By installing this library following libraries and their dependencies will be installed too.

Example

Sync example:

Link to GitHub: https://github.com/AGM-Studio/EasySQL/blob/master/sync_test.py

import EasySQL

# Enable debug mode if you like to get SPAMMED with SQL!
EasySQL.enable_debug()

# Simply provide connection info to your database
database = EasySQL.SyncedDatabase(
    database="MyDatabase",
    password="", # host, port and user set by default to usual localhost settings
)

# In V5 the table is now merged with table! Access the table through User.table!
class User(EasySQL.SQLData, database=database, name="MyTable"):
    id = EasySQL.SQLColumn("ID", EasySQL.Types.BIGINT, EasySQL.PRIMARY, EasySQL.AUTO_INCREMENT)
    name = EasySQL.SQLColumn("Name", EasySQL.Types.STRING(255), EasySQL.NOT_NULL, default="Missing!")
    balance = EasySQL.SQLColumn("Balance", EasySQL.Types.BIGINT.UNSIGNED, EasySQL.NOT_NULL) # int default is 0, no need to pass it
    premium = EasySQL.SQLColumn("Premium", EasySQL.Types.BOOL, EasySQL.NOT_NULL, default=False)

# Make sure to call database prepare once after a table is defined.
# No need to do it per table, just one after all tables is enough.
database.prepare()

# Insert values with a simple command giving the data object!
user_1 = User(name="Ashenguard", balance=100, premium=True) # Uses the default for any field mising!
User.table.insert(user_1)       # Give a premade object...
User.table.insert(name="Bob")   # Or let the method creates it!

# Let's  also add some random data
from random import randint
for i in range(5):
    User.table.insert(name=f"User-{i}", balance=randint(0, 20))

# Selecting data with another simple command which returns a list of data fetched.
### Let's get all the data
all_data = User.table.select()
no_one = User.table.select(User.name == "NO-ONE") # This is Still a list
mid_class = User.table.select(EasySQL.WhereIsBetween(User.balance, 50, 150))
print(all_data, no_one, mid_class)
### If you want only one object, then get one! Will return a User or None
one_user = User.table.select_one(User.name == "Ashenguard")
print("Type:", type(one_user))  # Prints User!
### You can also define order, descending, limit and offset too!
mixed = User.table.select(descending=True, limit=2, order=User.balance, offset=1)
print(mixed)

# Advanced Where clauses!
### While ==, !=, <, >, <=, >= work for common where clauses you can have them chained by binary operators
eg_and = (User.id != 0) & (User.id < 5)
eg_or = (User.id != 0) | (User.id < 5)
eg_not = ~ (User.id > 5)
### You also have access to more advanced ones like:
EasySQL.WhereIsIn(User.id, [0, 1, 2])
EasySQL.WhereIsBetween(User.id, 0, 5)
EasySQL.WhereIsLike(User.name, "Ash%")
### You can chain them with binary operators with general Where clauses or use AND, OR, NOT!
EasySQL.WhereIsIn(User.id, [0, 1, 2]).AND(User.name == "Ash")
EasySQL.WhereIsEqual(User.id, 5) | EasySQL.WhereIsIn(User.id, [0, 1, 2])
EasySQL.WhereIsIn(User.id, [0, 1, 2]) | ((User.id != 0) & (User.id < 5))

# Finally to update data you have also 2 approaches!
### A. Let the object auto updates itself:
### This approach will generate the Where clause by PRIMARY tags. Which means you can't change a primary value.
one_user.balance += 5
User.table.update(one_user) # The Where clause will be as if you've done: "User.id == one_user.id"
### B. Give the where clause yourself!
### It's useful if you have no primary key in your table, or you want to change a primary value!
User.table.update_where(User.id == 1, premium=True)
### You can also use the insert pattern and pass a whole new object, and it will update it whole!
User.table.update_where(User.id == 2, User(name="Chosen one!", balance=1000000, premium=True))

# Delete data with simple commands again!
User.table.delete(User.id > 2)

Async example

Link to GitHub: https://github.com/AGM-Studio/EasySQL/blob/master/async_test.py

import EasySQL

# The goal is to have both sync and async be the same as much as we can!
# Check sync example for basic information, here only async related differences are shown!
EasySQL.enable_debug()

# Tables and database should be defined before the main loop starts
database = EasySQL.AsyncDatabase(
    database="MyDatabase",
    password="",
)

# It doesn't matter if you use SQLData or AsyncSQLData, SQLData will create the table based on the type of database.
# But for IDE Compatibility we recommend to use AsyncSQLData for your async project!
class User(EasySQL.AsyncSQLData, database=database, name="MyTable"):
    id = EasySQL.SQLColumn("ID", EasySQL.Types.BIGINT, EasySQL.PRIMARY, EasySQL.AUTO_INCREMENT)
    name = EasySQL.SQLColumn("Name", EasySQL.Types.STRING(255), EasySQL.NOT_NULL, default="Missing!")
    balance = EasySQL.SQLColumn("Balance", EasySQL.Types.BIGINT.UNSIGNED, EasySQL.NOT_NULL) # int default is 0, no need to pass it
    premium = EasySQL.SQLColumn("Premium", EasySQL.Types.BOOL, EasySQL.NOT_NULL, default=False)


# All other tasks should be done inside a main loop!
# Everything is the same as the sync, but we need to await all database requests...
async def main():
    await database.prepare()

    user_1 = User(name="Ashenguard", balance=100, premium=True)
    await User.table.insert(user_1)
    await User.table.insert(name="Bob")

    from random import randint
    for i in range(5):
        await User.table.insert(name=f"User-{i}", balance=randint(0, 20))

    all_data = await User.table.select()
    no_one = await User.table.select(User.name == "NO-ONE")
    mid_class = await User.table.select(EasySQL.WhereIsBetween(User.balance, 50, 150))
    print(all_data, no_one, mid_class)

    one_user = await User.table.select_one(User.name == "Ashenguard")
    print("Type:", type(one_user))

    mixed = await User.table.select(descending=True, limit=2, order=User.balance, offset=1)
    print(mixed)

    # Where clauses have no ASYNC change!
    eg_and = (User.id != 0) & (User.id < 5)
    eg_or = (User.id != 0) | (User.id < 5)
    eg_not = ~ (User.id > 5)

    EasySQL.WhereIsIn(User.id, [0, 1, 2])
    EasySQL.WhereIsBetween(User.id, 0, 5)
    EasySQL.WhereIsLike(User.name, "Ash%")

    EasySQL.WhereIsIn(User.id, [0, 1, 2]).AND(User.name == "Ash")
    EasySQL.WhereIsEqual(User.id, 5) | EasySQL.WhereIsIn(User.id, [0, 1, 2])
    EasySQL.WhereIsIn(User.id, [0, 1, 2]) | ((User.id != 0) & (User.id < 5))


    one_user.balance += 5
    await User.table.update(one_user)
    await User.table.update_where(User.id == 1, premium=True)
    await User.table.update_where(User.id == 2, User(name="Chosen one!", balance=1000000, premium=True))

    await User.table.delete(User.id > 2)


# Let's run the main loop!
