Incorrect string value xE6x9Ax82xE6x97xA0 for column 书名 at row 1

This error message suggests that the string value being inserted into the '书名' (Book Name) column is incorrect. The value '\xE6\x9A\x82\xE6\x97\xA0' is likely a sequence of hexadecimal escape characters that cannot be properly interpreted as a valid string value in the specified column.

To resolve this issue, you may need to ensure that the value being inserted is in the correct format and encoding for the '书名' column. It could be necessary to check the character encoding settings of the column or the database and make sure they are compatible.

If the value is intended to be in a different character encoding, you may need to convert it to the correct encoding before inserting it into the database
