研究方向

Locate the code that generates the error message 'Table has no partition for value from column list' in TiDB's partition handling (likely in 'table/partition.go' or similar). Modify the error string to include the actual column value that is not found in any partition. Ensure the value is properly quoted to avoid SQL injection in the error output. Check the existing tests for partition error messages to add a test case covering this new error format.
