**File Structure Before:** - sql_functions.go (850+ lines) - sql_functions_test.go (1,205+ lines) **File Structure After:** - function_helpers.go (105 lines) - shared utility functions - arithmetic_functions.go (205 lines) - arithmetic operators & math functions - datetime_functions.go (170 lines) - date/time functions & constants - string_functions.go (335 lines) - string manipulation functions - arithmetic_functions_test.go (560 lines) - tests for arithmetic & math - datetime_functions_test.go (370 lines) - tests for date/time functions - string_functions_test.go (270 lines) - tests for string functions **Benefits:** ✅ Better organization by functional domain ✅ Easier to find and maintain specific function types ✅ Smaller, more manageable file sizes ✅ Clear separation of concerns ✅ Improved code readability and navigation ✅ All tests passing - no functionality lost **Total:** 7 focused files (1,455 lines) vs 2 monolithic files (2,055+ lines) This refactoring improves maintainability while preserving all functionality.
