How to resolve errors when writing to MySQL using str_to_date?

When using the MySQL STR_TO_DATE function, errors may occur. Here are some common solutions:

1. Check if the date format is correct: The STR_TO_DATE function requires a correct date string and a format string as parameters. If the date string format is incorrect, it will result in an error. Make sure the date string and format string match.
2. Use the appropriate format string: Make sure to use the correct format string to match the format of the date string. For example, if the date string is “2020-01-01”, the format string should be “%Y-%m-%d”.
3. Check if the date string is empty: If the date string is empty, the STR_TO_DATE function will return NULL. Ensure that the date string is not empty.
4. Ensure that the SQL mode of MySQL allows the use of the STR_TO_DATE function. In certain situations, MySQL’s SQL mode may not permit the use of the STR_TO_DATE function. You can check the current SQL mode using the following command: SELECT @@sql_mode; If the mode includes restrictions such as “NO_ZERO_DATE” or “STRICT_TRANS_TABLES”, you may need to modify the SQL mode.
5. Remove invalid characters: If the date string contains invalid characters, the STR_TO_DATE function may not be able to correctly parse the date. Make sure that the date string only contains valid date characters, such as numbers and separators.
6. Try using other date handling functions if the STR_TO_DATE function cannot parse the date string, such as DATE_FORMAT or UNIX_TIMESTAMP. These functions can convert the string into a date as needed.

If the aforementioned methods still fail to solve the problem, providing more error information and code examples can help better understand and resolve the issue.
