The provided code snippet is mostly clear and functional. Here's a brief review along with some suggestion for improvement:

Key Points to Check:

1. Imports: The setting.models module seems intended to be imported at two different levels, which might not be necessary or correct depending on how the modules are organized. It might make sense to consolidate the import if possible.

2. SQL Execution Functionality:

   • Common Module Location: Ensure that common/db/sql_execute.py exists and contains an update_execute function. This should handle the database execution more robustly.
   • Error Handling: Consider adding error handling to manage exceptions during SQL execution, particularly if it's running against production systems.

3. SQL Query:

   • Security Risks: Be cautious of using SQL injection through string formatting. Consider parameterized queries where available (e.g., using SQLAlchemy).
   • Documentation: If this query updates multiple tables, document its purpose and dependencies clearly.

4. Code Structure: Review the structure of the file to ensure consistency. Having imports near the top and methods grouped logically can improve readability and maintainability.

Optimization Suggestions:

• Consolidate Imports: Remove unnecessary duplicates and place all imports at the beginning unless specific order changes behavior.

• Use Object-Oriented Principles: If applicable, consider refactoring model classes from setting.models.Model into their own files for better organization.

• Parameterize Queries: Use prepared statements (?) instead of string concatenation to avoid SQL Injection risks and enhance security.

Example Improvement:

import common.db.sql_execute

# Assuming sql_execute has an execute method accepting parameters
sql_statement = """
UPDATE "public"."document" t1 
JOIN another_table t2 ON t1.id = t2.document_id
SET t1.status = ?, t2.some_column = ?;
"""
params = ('new_status', 'some_value')
common.db.sql_execute.execute(sql_statement, params)

This example assumes sql_execute.execute() accepts both the SQL statement and parameters as separate arguments, making it safer and potentially easier to extend or test.
