我收到此错误＆＃34;错误将数据类型NVARCHAR转换为INT＆＃34;当我尝试执行一个准备好的Statement时，将一个String CSV（@selectedResources）传递给SQL Server存储过程中的VARCHAR参数：
Java代码：
public void setFields(IEntity argEntity, StormPS pstmt) throws SQLException {
IMeal t_Meal = (IMeal) argEntity;
pstmt.setInt(1, t_Meal.getTourId());
pstmt
.setTimestamp(2, StormContext
.dateToTimestamp(t_Meal.getDateTimeStartActual()));
pstmt.setTimestamp(3, StormContext.dateToTimestamp(t_Meal.getDateTimeEndActual()));
pstmt.setInt(4, t_Meal.getJobElementId());
pstmt.setBoolean(5, t_Meal.getOTE());
pstmt.setBoolean(6, t_Meal.getBillable());
pstmt.setBoolean(7, t_Meal.getAutoAdd());
pstmt.setInt(8, t_Meal.getUpdatingUserId());
pstmt.setString(9, t_Meal.getIpAddress());
pstmt.setString(10, t_Meal.getSelectedResources());
}
存储过程的参数：
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[MealUpdate]
@@TourId INT,
@@DateTimeStartActual DATETIME,
@@DateTimeEndActual DATETIME,
@@JobElementId INT,
@@OTE BIT,
@@Billable BIT,
@@AutoAdd BIT,
@@UpdatingUserId INT,
@@IPAddress VARCHAR(20),
@@SelectedResources VARCHAR(300)
起初我觉得我的preparedStatement已经定义了这样的参数[9105267,2016-05-18 04：30：00.0,2016-05-18 05：30：00.0,0，false，false，false，23939 ，127.0.0.1， 8224483,8149293,8149281,8149272 ]（值＆＃39; 8224483,8149293,8149281,8149272＆＃39;是@selectedResources String参数）。然后我决定在这个字符串中添加单引号[9105267,2016-05-18 04：30：00.0,2016-05-18 05：30：00.0,0，false，false，false，23939,127.0.0.1 ，＆＃39; 8224483,8149293,8149281,8149272＆＃39; ]，但同样的错误仍然显示。
我希望我的问题足够明确。

更新（解决方案）：
在执行preparedStatement的Java类中，有一个常量，它定义将作为参数发送的字段数，此常量在9中定义：
private final static int FIELDS_NUMBER = 9;
当我添加一个新参数（selectedResources）时，我需要将此常量重新定义为10.我将@selectedResouces发送到@Id（其类型为int）的位置。这基本上是我收到此错误的原因。一种初学者的错误。
