String searchPerson = "select * from persons where surname like ? and name like ?";
//connect to DB
PreparedStatement statement = connect.prepareStatement(searchPerson);
statement.setString(1,"%"+ surname + "%");
statement.setString(2, "%" + name + "%");
ResultSet resultPerson = statement.executeQuery(searchPerson);
//..code
you have an error in your sql Syntax; check the manual that corresponds to your MysqL server version for the right Syntax to use near ‘?’
解决方法:
您应该执行不带参数的PrepareStatement,如下所示：
statement.executeQuery()
使用String参数调用executeQuery将按原样执行提供的查询(没有绑定参数).
