mysql  update 报错

错误：Caused by: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Truncated incorrect DOUBLE value: 'hello'

错误原因：sql语句写错了

错误sql：

String updateSql = "UPDATE user SET username = ? AND password = ? WHERE id = ?";

正确sql：

String updateSql = "UPDATE user SET username = ? , password = ? WHERE id = ?";
