Java 有人认为我的更新或插入查询有问题吗？我使用的是事先准备好的声明

public void insertOrUpdate（字符串customerNumber，Long creditLimitAmount） 抛出SQLException{

Connection connection2 = UBOCMSSQLConnectionUtill.getMSSqlConnection();
connection2.setAutoCommit(false);

更新查询中有21个参数，但您只为其中20个设置值

---

文森特是对的。更新查询有21个参数，插入查询有20个参数。但是，在代码中，您只为更新查询设置了20个参数

---

LIMITMEMBER是参数3和21。

@aditya86c我替换了你的？用数字显示您实际拥有的参数数量。但我仍然看到此错误[Microsoft][SQLServer 2000 JDBC驱动程序]对象已关闭。是否有人认为我的insert语句有错误，特别是在BRI，我在“BR”附近得到了此java.sql.SQLException:[Microsoft][SQLServer 2000 JDBC驱动程序][SQLServer]错误的语法。
