如何使用存储过程将（asp.net项目）文本值传递给SQL中的money数据类型？

问题描述

我正在使用Visual Studio 2010和SQL.I创建了Asp.Net Web应用程序。我正在使用存储过程将值传递给数据库。



在数据库中，我创建了一个名为project的表，其中包含一些字段，其中两个字段数据类型为 MONEY ，列名为expectedtotalcost和actualtotalcost

ASP.NET代码：

Hi,i am using Visual studio 2010 and SQL.I have created Asp.Net web application.I am using stored procedure to pass values to database.

In database,i have created a table called project which contains some fields in which two of the field data type is MONEY and column name is "expectedtotalcost" and actualtotalcost"
ASP.NET code:

  public void InsertProjectBasicInfo( string expectedtotalcost, string actualtotalcost)
    {
        SqlConnection sqlcon;
        SqlCommand sqlcmd;
        double money;
        try
        {
            sqlconnstring = ConfigurationManager.ConnectionStrings["CONERP"].ConnectionString;
            sqlcon = new SqlConnection(sqlconnstring);
            sqlcon.Open();
            sqlcmd = new SqlCommand("CreateNewProject", sqlcon);
            sqlcmd.CommandType = CommandType.StoredProcedure;
           
            sqlcmd.Parameters.Add("@expectedtotalcost", SqlDbType.Money).Value =
                Double.TryParse(expectedtotalcost, out money);
            sqlcmd.Parameters.Add("@actualtotalcost", SqlDbType.Money).Value =
                Double.TryParse(actualtotalcost, out money);
            sqlcmd.ExecuteNonQuery();
            sqlcmd.Dispose();
            sqlcon.Close();
        }
        catch (SqlException sqlerr)
        {

        }
    }
InsertProjectBasicInfo(txtExpectedProjectCost.Text.Trim(), txtActualProjectCost.Text.Trim());

SQL查询：

SQL Query:

USE [COERP]
GO
/****** Object:  StoredProcedure [dbo].[CreateNewProject]    Script Date: 10/15/2013 10:43:59 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[CreateNewProject](
	
	@expectedtotalcost money ,
	@actualtotalcost money)
as
begin
	insert into Project values(@expectedtotalcost,
	@actualtotalcost)
end

没有错误信息.. ??值总是1.0。如果你按步骤格式提供答案，将会有所帮助。



谢谢

推荐答案

          sqlcmd.CommandType = CommandType.StoredProcedure;
           sqlcmd.Parameters.AddWithValue("@expectedtotalcost", expectedtotalcost);
           sqlcmd.Parameters.AddWithValue("@actualtotalcost", actualtotalcost);          
           sqlcmd.ExecuteNonQuery();

in palace of 

            sqlcmd.CommandType = CommandType.StoredProcedure;           
            sqlcmd.Parameters.Add("@expectedtotalcost", SqlDbType.Money).Value =
                Double.TryParse(expectedtotalcost, out money);
            sqlcmd.Parameters.Add("@actualtotalcost", SqlDbType.Money).Value =
                Double.TryParse(actualtotalcost, out money);
            sqlcmd.ExecuteNonQuery();
