报错：
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Invalid parameter binding(s).
请大侠们帮忙解决，小弟先谢过了
------解决方案--------------------
因为你有：
stat.setString(1,reg_name);
stat.setString(2,reg_pass);
所以要把
stat=conn.prepareStatement( "insert user1(user1.name,user1.pass) values( ' "+reg_name+ " ', ' "+reg_pass+ " ') ");
改成
stat = conn.prepareStatement( "insert user1(user1.name,user1.pass) values(?,?) ");
否则它找不到匹配的参数。
