About

Use databases without thinking about SQL. Let me show you how sqllex makes your life easier. Imagine you need create some database, save some data into it and take it back. That's how your code will look like.

from sqllex import *

# Create some database, with simple structure
db = SQLite3x(
    path='my_data.db',
    template= {
        "users": {
            "username": [TEXT, NOT_NULL],
            "age": INTEGER,
        }
    }
)

# Insert some data
db.insert('users', ['Sqllex', 33])

# Take it back
users = db.select('username', from_table='users', where={'age': 33})

print(users)  # [('Squllex',)]

Ok, what if you need more complex structure with FOREIGN KEYs? Not a big deal.

from sqllex import *

DB_TEMPLATE = {
    "groups": {
        "group_id": [INTEGER, PRIMARY_KEY, UNIQUE],
        "name": [TEXT, NOT_NULL, DEFAULT, 'Unknown'],
    },

    "users": {
        "username": [TEXT, NOT_NULL],
        "group_id": INTEGER,

        FOREIGN_KEY: {
            "group_id": ["groups", "group_id"]
        },
    }
}

# and do your business ...

What if I have LARGE dataset to insert? Still easy.

...
# Your awesome dataset
dataset = [
    [3, "pi", 0],
    [1, "pi", 1],
    [4, "pi", 2],
    [1, "pi", 3],
    [5, "pi", 4],
    [9, "pi", 5],
    [2, "pi", 6],
    ...
]

# One line
db.insertmany('math', dataset)

# Done

from sqllex import *

db = SQLite3x(
    path='./path/my_awesome.db',
    template={
        "groups": {
            "group_id": [INTEGER, PRIMARY_KEY, UNIQUE],
            "name": [TEXT, NOT_NULL, DEFAULT, 'Unknown'],
        }
    }
)

# Insert some groups into groups table
db.insertmany(
    'groups',
    group_id=[1, 2],
    name=["Admin", "User"],
)


# Let's create a new table with some FOREIGN_KEYs
db.create_table(
    name='users',
    columns={
        "username": [TEXT, NOT_NULL, DEFAULT, 'Unknown'],
        "group_id": INTEGER,
        FOREIGN_KEY: {
            "group_id": ["groups", "group_id"]
        },
    },
    without_rowid=True,
    as_=__something__
)

# Insert some users into users table
db.insertmany(
    table='users',
    username=['User_1', 'User_2', 'User_3', 'User_4', 'User_5', 'User_6'],
    group_id=[1, 2, 1, 1, 2, 2]
)

db.insert(
    or_=REPLACE,
    table='users',
    username='User_4',
    group_id=1,
)

# ANd now take it back whith some conditions
users = db.select(
    select='username',
    table='users',
    where={
        'group_id': 2
    },
    order_by={
        'username': 'DESC'
    },
    with_=__something__,
    limit=10,
    offset=1,
    execute=True,
