Troubleshooting MySQL datetime data truncation errors in Java applications is a common problem, especially when dealing with large CSV files. This post explores the error "SqlExceptionHelper:146 - Data truncation: Incorrect datetime value..." specifically when loading the 'effDate' column. The issue arises on one server but not another, suggesting a potential configuration difference, not a fundamental application flaw. The error message indicates a likely problem with the 'effDate' value '57445-05-12 00:00:00' being outside the valid MySQL datetime range. The solution involves robust data validation in the Java application to ensure the correct format, efficient database insertion methods like batch processing and stored procedures, and meticulous checking of the date/time zone settings between servers. Proper validation of the CSV file's date format before processing is also crucial to prevent errors. This comprehensive guide provides detailed code examples and explanations to resolve this common issue, ensuring data integrity and application reliability.
