91-93: Consider adding tests for the insert method parameter.To prevent regression, add unit tests that validate:
- Default insert method behaviour
- Custom insert method validation
- Error handling with invalid insert methods
Would you like me to help create these unit tests?

91-93: Verify error handling with the fix.The PR objectives mention that this fix affects error handling during import. Let's verify the implementation:
#!/bin/bash # Description: Verify error handling in transfer method # Expected: Find error handling logic for different insert methods # Search for error handling in transfer method echo "Searching for error handling in transfer..." rg "INSERT.*INTO.*VALUES" -A 10 # Search for mysql_insert_method usage in SQL generation echo "Searching for insert method usage in SQL..." ast-grep --pattern 'if self._mysql_insert_method.upper() == $_'
91-93: LGTM! Bug fix correctly implemented.The fix properly sources the MySQL insert method from
mysql_insert_methodinstead of the incorrectmysql_integer_type. The validation logic ensures the value is within allowed methods, defaulting to "IGNORE" if invalid.Let's verify the available insert methods:
✅ Verification successful
Let me generate additional scripts to gather the necessary information about the MySQL insert methods and their usage.
Let me search specifically for the constant definition and its allowed values.
Let me try one final search with different patterns to locate the constant definition.
Let me check the mysql_utils.py file where the constant is defined.
Bug fix correctly validates against defined insert methods
Based on the verification results, I can confirm that:
- The
MYSQL_INSERT_METHODconstant is properly defined inmysql_utils.pyas a tuple containing three valid methods: "DEFAULT", "IGNORE", and "UPDATE"- The code correctly validates the input against these methods and defaults to "IGNORE" when invalid
- The implementation properly uses these methods in SQL generation, as seen in the transporter's INSERT statement handling
The fix is working as intended, with proper validation against the defined constants and correct fallback behaviour.

Description
There was a mistake in the transporter code, and the insert method property was being assigned the value from the
mysql_integer_typein the arguments instead ofmysql_insert_method. Which means that the--mysql-insert-methodparameter on the command line was effectively always ignored, and the import was swallowing the errors even if you told it not to… 🫠Type of change
How Has This Been Tested?
Tested on a small table in my database where a long string has been added in one row into a column which is defined as
VARCHAR(3)in MySQL (since SQLite doesn't support limits on text fields and lets you put as long strings as you want there). The import was succeeding even with-i DEFAULT, and now it fails as expected.Checklist:
