c# - ''(过程)的请求失败”，因为它是一个表对象 - 错误

Question

我有三个表:

• dbo.学生
• dbo.请求
• dbo.RequestLine(前两者之间的关联表，包含复合主键 STUD_ID 和 REQ_ID，以及属性 REQ_DATE)

我正在尝试将记录插入 dbo.RequestLine table 。但是，我收到一条错误消息:

System.Data.SqlClient.SqlException: The request for procedure 'RequestLine' failed because 'RequestLine' is a table object.

以下是三个表的 DDL 语句:

CREATE TABLE [dbo].[Request]
(
    [REQ_ID] [int] IDENTITY(10000005,1) NOT NULL,
    [REQ_STAT] [varchar](12) NULL,
    [REQ_CAT] [varchar](15) NULL,
    [ADMIN_ID] [smallint] NULL,
    [COOR_ID] [smallint] NULL,

    CONSTRAINT [PK_Request] 
        PRIMARY KEY CLUSTERED ([REQ_ID] ASC)
)

ALTER TABLE [dbo].[Request] WITH CHECK 
    ADD CONSTRAINT [FK_Request_Admin] 
        FOREIGN KEY([ADMIN_ID]) REFERENCES [dbo].[Admin] ([ADMIN_ID])
GO

ALTER TABLE [dbo].[Request] CHECK CONSTRAINT [FK_Request_Admin]
GO

ALTER TABLE [dbo].[Request]  WITH CHECK 
    ADD CONSTRAINT [FK_Request_Coordinator] 
        FOREIGN KEY([COOR_ID]) REFERENCES [dbo].[Coordinator] ([COOR_ID])
GO

ALTER TABLE [dbo].[Request] CHECK CONSTRAINT [FK_Request_Coordinator]
GO

CREATE TABLE [dbo].[Student]
(
    [STUD_ID] [int] IDENTITY(1000009,1) NOT NULL,
    [STUD_NAM] [varchar](30) NOT NULL,
    [STUD_EMAIL] [varchar](50) NULL,
    [CAMP_NAM] [varchar](50) NULL,
    [CAMP_ZIP] [int] NULL,
    [STUD_TYP] [char](5) NOT NULL,

    CONSTRAINT [PK_Student] 
        PRIMARY KEY CLUSTERED ([STUD_ID] ASC)
) 
GO

ALTER TABLE [dbo].[Student] WITH CHECK 
    ADD CONSTRAINT [FK_Student_Campus] 
        FOREIGN KEY([CAMP_NAM], [CAMP_ZIP]) REFERENCES [dbo].[Campus] ([CAMP_NAM], [CAMP_ZIP])
GO

ALTER TABLE [dbo].[Student] CHECK CONSTRAINT [FK_Student_Campus]
GO

CREATE TABLE [dbo].[RequestLine]
(
    [STUD_ID] [int] NOT NULL,
    [REQ_ID] [int] NOT NULL,
    [REQ_DATE] [date] NOT NULL,

    CONSTRAINT [PK_RequestLine] 
        PRIMARY KEY CLUSTERED ([STUD_ID] ASC, [REQ_ID] ASC)
)
GO

ALTER TABLE [dbo].[RequestLine]  WITH CHECK 
    ADD CONSTRAINT [FK_RequestLine_Request] 
        FOREIGN KEY([REQ_ID]) REFERENCES [dbo].[Request] ([REQ_ID])
GO

ALTER TABLE [dbo].[RequestLine] CHECK CONSTRAINT [FK_RequestLine_Request]
GO

ALTER TABLE [dbo].[RequestLine]  WITH CHECK 
    ADD CONSTRAINT [FK_RequestLine_Student] 
        FOREIGN KEY([STUD_ID]) REFERENCES [dbo].[Student] ([STUD_ID])
GO

ALTER TABLE [dbo].[RequestLine] CHECK CONSTRAINT [FK_RequestLine_Student]
GO

这是我拥有的三个存储过程:

ALTER PROCEDURE [dbo].[Req_InsertNew]
    (@REQ_STAT varchar(12),
     @REQ_CAT varchar(15),
     @ADMIN_ID smallint,
     @COOR_ID smallint)
AS
BEGIN
    SET NOCOUNT ON

    INSERT INTO dbo.Request (REQ_STAT, REQ_CAT, ADMIN_ID, COOR_ID)
    VALUES (@REQ_STAT, @REQ_CAT, @ADMIN_ID, @COOR_ID);

    DECLARE @REQ_ID INT
    SET @REQ_ID = SCOPE_IDENTITY()
    SELECT @REQ_ID
END

ALTER PROCEDURE [dbo].[Stud_InsertNew2]
    (@STUD_NAM varchar(30),
     @STUD_EMAIL varchar(50),
     @CAMP_NAM varchar(50),
     @CAMP_ZIP int,
     @STUD_TYP char(5))
AS
BEGIN
    DECLARE @temptable TABLE (newSTUDID int, STUDTYPE char);

    SET NOCOUNT ON

    INSERT INTO dbo.Student(STUD_NAM, STUD_EMAIL, CAMP_NAM, CAMP_ZIP, STUD_TYP)
    VALUES (@STUD_NAM, @STUD_EMAIL, @CAMP_NAM, @CAMP_ZIP, @STUD_TYP);

    DECLARE @STUD_ID INT
    SET @STUD_ID = SCOPE_IDENTITY()
    SELECT @STUD_ID
END

ALTER PROCEDURE [dbo].[ReqLine_Insert]
    (@STUD_ID int,
     @REQ_ID int,
     @REQ_DATE date)
AS
BEGIN
    INSERT INTO dbo.RequestLine (STUD_ID, REQ_ID, REQ_DATE)
    VALUES (@STUD_ID, @REQ_ID, @REQ_DATE)
END

我正在尝试使用 ExecuteScalar()检索REQ_ID和STUD_ID并将它们放入 RequestLine table 。

这是 C# 代码:

int campzip = int.Parse(ddlCamp.SelectedValue.Trim());
int adminid = int.Parse(ddlAdmin.SelectedValue.Trim());
int coorid = int.Parse(txtCoorID.Text.Trim());

DateTime ReqDate = DateTime.ParseExact(txtReqDate.Text, "yyyy-MM-dd", null);

using (var connection = new System.Data.SqlClient.SqlConnection(Helper.CnnVal("cis-laredoConnectionString")))
{
    connection.Open();

    var cmd = new SqlCommand("dbo.Stud_InsertNew2", connection);
    cmd.CommandType = CommandType.StoredProcedure;

    cmd.Parameters.AddWithValue("@STUD_NAM", txtStdName.Text);
    cmd.Parameters.AddWithValue("@STUD_EMAIL", txtStdEmail.Text);
    cmd.Parameters.AddWithValue("@CAMP_NAM", ddlCamp.SelectedItem.ToString());
    cmd.Parameters.AddWithValue("@CAMP_ZIP", campzip);
    cmd.Parameters.AddWithValue("@STUD_TYP", "Other");

    int STUD_ID = (int)cmd.ExecuteScalar();
    cmd.Dispose();

    connection.Close();

    connection.Open();

    var cmd1 = new SqlCommand("dbo.Req_InsertNew", connection);
    cmd1.CommandType = CommandType.StoredProcedure;

    cmd1.Parameters.AddWithValue("@REQ_STAT", "Submitted");
    cmd1.Parameters.AddWithValue("@REQ_CAT", "Uniform");
    cmd1.Parameters.AddWithValue("@ADMIN_ID", adminid);
    cmd1.Parameters.AddWithValue("@COOR_ID", coorid);;

    int REQ_ID = (int)cmd1.ExecuteScalar();

    cmd1.Dispose();
    connection.Close();

    // post back info. to dbo.RequestLine table in sql server
    connection.Open();

    var cmd2 = new SqlCommand("dbo.ReqLine_Insert", connection);
    cmd2.CommandType = CommandType.StoredProcedure;

    cmd2.Parameters.AddWithValue("@STUD_ID", STUD_ID);
    cmd2.Parameters.AddWithValue("@REQ_ID", REQ_ID);
    cmd2.Parameters.Add("@REQ_DATE", SqlDbType.Date).Value = ReqDate;

    cmd2.ExecuteNonQuery();
    cmd2.Dispose();

    connection.Close();
}

如有任何帮助，我们将不胜感激!

Answer 1

您应该更改此设置:

var cmd2 = new SqlCommand("dbo.RequestLine", connection);

这样:

var cmd2 = new SqlCommand("dbo.ReqLine_Insert", connection);

对象dbo.RequestLine是一个表，而您需要存储过程dbo.ReqLine_Insert来向该表插入数据。
