Refactor code for improved readability and consistency

- Consolidated multiline string formatting into single-line for SQL queries in multiple files.
- Adjusted argument formatting in function calls for better alignment and readability.
- Removed unnecessary line breaks and improved spacing in various sections of the codebase.
- Updated test cases to maintain consistency in formatting and improve clarity.
