WaveSQL 1.0.5

SQL helper for databases

🌊 WaveSQL

Read this in Russian

WaveSQL is a lightweight yet powerful Python library for secure, synchronous and asynchronous interaction with MySQL and MariaDB.

Developed by WaveTeam under the leadership of eelus1ve

🚀 Features

• 🔌 Easy database connection via config.ini or dictionary
• ⚙️ Automatic database schema initialization on first run
• 🧠 Support for calling stored procedures (CALL)
• 🪝 Protected methods (via @protected) — prevent direct calls to critical ftextions
• 🐍 Asynchronous version with the same API
• 🪵 Built-in logging to database + colored console output (colorama)
• 🧠 Automatic generation of Python code (Python Bridge) from SQL files
• 🧩 Flexible configuration: dictionary=True, colored output, pprint, backtrace control
• 🛡️ Error catching and logging with traceback
• 🧪 Protection against missing or incomplete SQL files

📦 Installation

pip install wavesql

🧰 Usage

🔹 Simple example

from wavesql.sync import WaveSQL

db = WaveSQL(
    is_dictionary=True,
    is_console_log=True,
    is_log_backtrace=True,
    is_auto_start=True
)

db.log(level=3, text="All is good!")

---

🌀 Asynchronous version

from wavesql.aio import AsyncWaveSQL

adb = AsyncWaveSQL(
    is_dictionary=True,
    is_console_log=True,
    is_log_backtrace=True,
    is_auto_start=True
)

await adb.log(level=3, text="Async logging works!")

All methods and behavior are identical to the synchronous version.

Just use await and import AsyncWaveSQL from wavesql.aio.

🧠 Generating Python code from SQL

If your SQL directory contains a queries.sql file, WaveSQL can automatically generate Python code to call the SQL queries defined in it.

Example content of queries.sql:

create get_user with query SELECT * FROM users WHERE id = {% extend user_id : int %} LIMIT 1;

Explanation of syntax:

• create get_user — declares the function/method name to be generated.

• with query — keyword indicating the following is the SQL query.

• Inside the query, {% extend user_id : int %} means the generated method will have a parameter user_id of type int.

• The SQL query safely substitutes this parameter (with %s or equivalent) to prevent SQL injection.

Simply enable the flag is_create_python_bridge=True during initialization:

db = WaveSQL(
    is_create_python_bridge=True,
    ...
)

The following files will be created:

• database.py — synchronous interface

• asyncdatabase.py — asynchronous interface

• aio.py — entry point for async API

• __init__.py — entry point for sync API

• library SQL files that initialize the database and create minimal necessary tables for proper module operation

🧰 Usage with is_create_python_bridge=True

📁 Project structure (before running run.py):

database/
├── sql/
│   ├── 2_init_users.sql
│   └── queries.sql
├── run.py

🐍 run.py file:

from wavesql.sync import WaveSQL

db = WaveSQL(
    config="path_to_my_settings.ini", path_to_sql="database/sql", is_console_log=True,
    is_log_backtrace=True, is_auto_start=True, is_create_python_bridge=True
)

Files with names containing _init_ and a numeric prefix (e.g., 0_init_users.sql) are initialized in the database in ascending order of this number. The prefix must be a non-negative integer — negative values are reserved by the library.

The queries.sql file is used for automatic generation of query methods that create two bridges (sync and async).

Example queries.sql:

create get_user with query SELECT * FROM users WHERE id = {% extend user_id : int %} LIMIT 1;

Output:

# database.py
def get_user(self, user_id: int) -> dict | None:
    return self._db_query("SELECT * FROM users WHERE id = %s LIMIT 1", (user_id, ), fetch=1)

# asyncdatabase.py
async def get_user(self, user_id: int) -> dict | None:
    return await self._db_query("SELECT * FROM users WHERE id = %s LIMIT 1", (user_id, ), fetch=1)
