• ✅ Supports MySQL and SQLite
• ✅ Clean API for integration
• ✅ Lightweight and dependency-minimized

Quickstart

from sqloader.init import database_init

config = {
    "type": "mysql",
    "mysql": {
        "host": "localhost",
        "port": 3306,
        "user": "root",
        "password": "pass",
        "database": "mydb"
    },
    "service": {
        "sqloder": "res/sql/sqloader/mysql"
    },
    "migration": {
        "auto_migration": True,
        "migration_path": "res/sql/migration/mysql"
    },
}

db, sqloader, migrator = database_init(config)

# Example usage
query = sqloader.load_sql("user_info", "user.get_user_by_id")
result = db.fetch_one(query, ['abc', 123])

SQL Loading Behavior

• If the value in the .json file ends with .sql, the referenced file will be loaded from the same directory.
• Otherwise, the value is treated as a raw SQL string.

Example JSON file user.json:

{
  "user": {
    "get_user_by_id": "SELECT * FROM users WHERE id = %s",
    "get_all_users": "user_all.sql"
  },
  "get_etc": "SELECT * FROM etc"
}
