sqlite3dict 0.0.1

Wrapper around sqlite3 to work with dictionaries

Wrapper around sqlite3 which allows working simply with python dictionaries as well as combining it with sql syntax.

Main scope of this project:

• Simple store for json documents combined with fast searching capabilities of Sqlite3
• Support big volumes of data (millions of records)
• Combine best features of NOSQL and SQL
• Elimintate the need to work with SQL DDL

Sample code:

from sqlite3dict import Storage

from datetime import datetime

# ******************************************************************************
# * Test
# ******************************************************************************
with Storage("test.sqlite") as store:

    definitions = {
        "name": "TEXT", 
        "age": "INTEGER", 
        "amount": "DOUBLE", 
        "createdate": "DATETIME",
        "resident": "BOOLEAN"
    }

    # This creates the table (collection) only if it does not exist already
    collection = store.init_collection("test", definitions)

    # Insert data
    collection.insert({
        "name": "John Doe", 
        "age": 25, 
        "amount": 100.23, 
        "createdate": datetime.now(),
        "resident": True,
        "additional": {
            "prop1": 1,
            "prop2": 1,
            "other": ["A", "B"]
        }
    })

    collection.insert({
        "name": "John Doe", 
        "age": 10, 
        "amount": 100.00, 
        "createdate": datetime.now(),
        "resident": True
    })

    # Update inserted data by given criteria
    collection.update().data({
        "createdate": datetime.now(), 
        "age": 15, 
        "amount": 99.38, 
        "resident": False
    }).where("age = 25").execute()

    # Simple query for data
    list = collection.query().where("age = 15").limit(10).offset(0).order("createdate", "ASC").order("ID").execute()

    for item in list:
        print("item:", item)

    # Delete data by given criteria
    collection.delete().where("age = 15").execute()

    # Native SQL query in case you still need it
    items = store.query_native("select * from test")
    for item in items:
        print("native item:", item)

    # Drop table (collection)    
    store.delete_collection("test")
