在寫sql查詢語句queryRunner.update(connection,"update account set balance=? where name=?",account.getName(),account.getBalance());時出現java.sql.SQLException: Data truncation: Truncated incorrect DOUBLE value: 'zhangsan' Query: update account set balance=? where name=? Parameters: [zhangsan, 800]異常,
原因是查詢語句里的參數account.getName(),account.getBalance()位置寫反了,應該與sql語句里的一致.
