The error message “Incorrect string value” indicates a character encoding issue in the database. The string you are trying to insert contains characters that cannot be properly represented in the character set used by the database column.
Here are some solutions to resolve the exception:
1. Ensure that the character set and collation of the column in your database table are compatible with the characters you intend to insert. If, for instance, your column has a VARCHAR datatype, and you’re attempting to insert special symbols such as the Indian Rupee symbol (₹), you are likely to encounter the described error. To mitigate this exception, confirm that your columns are configured appropriately to support the Indian Rupee symbol and other special characters. Consider utilizing a character set such as ‘utf8mb4’ and a collation like ‘utf8mb4_unicode_ci’ to accommodate a broader spectrum of characters.
ALTER TABLE your_table_name
MODIFY COLUMN column_name VARCHAR(your_desired_length)
CHARACTER SET utf8mb4
COLLATE utf8mb4_unicode_ci; 2. Make sure that your application is set up to handle and send data in the correct character encoding. This is especially important when inserting or updating data in the column.
3. Validate and sanitize user inputs to prevent any unexpected characters from being inserted into the database.
4. Ensure that the database connection is using the correct character set. This is important for both the database connection configuration and the application connecting to the database.
