Question

我的C＃代码：

var Message = new SqlParameter("Message", SqlDbType.VarChar, 8000);

Message.Direction = ParameterDirection.Output;

var UserId = new SqlParameter("UserId ", SqlDbType.BigInt);
UserId.Value = Convert.ToInt64(System.Web.HttpContext.Current.Session["UserIDKey"]);

var utblProgramAllotment = new SqlParameter("utblProgramAllotment", SqlDbType.Structured);
utblProgramAllotment.Value = dtProgrammeAllotments;
utblProgramAllotment.TypeName = "dbo.utblProgramAllotment";

try
{
    db.Database.ExecuteSqlCommand(
         "exec uspInsertUpdateProgrammeAllotment    @UserId , @utblProgramAllotment, @Message OUTPUT",
         UserId, utblProgramAllotment, Message);
}
catch (Exception ex)
{
    vm.Message = ex.Message.ToString();
    Errorlog.WriteErrorlog(ex, "Programme Allotment", "");

我的程序接受：

ALTER PROCEDURE   [dbo].[uspInsertUpdateProgrammeAllotment] 
(      
    @utblProgramAllotment AS utblProgramAllotment READONLY,
    @UserId Bigint,
   @Message VARCHAR(8000) OUTPUT    
)

用户定义的表类型为

CREATE TYPE [dbo].[utblProgramAllotment] AS TABLE(
    [ProgrammeScheduleIDKey] [bigint] NOT NULL,
    [ProposalDetailsIDKey] [bigint] NOT NULL,
    [SanctionOrderIDKey] [bigint] NOT NULL,
    [ProgrammeIDKey] [bigint] NOT NULL,
    [EmployeeIDKey] [bigint] NOT NULL,
    [DistrictIDKey] [bigint] NOT NULL,
    [TargetGroupIDKey] [bigint] NOT NULL,
    [ProgrammeTitleIDKey] [bigint] NOT NULL,
    [ProgramMode] [varchar](3) NOT NULL,
    [ProgrammeDescription] [varchar](500) NOT NULL,
    [ScheduleStartDateDt] [datetime] NULL,
    [ApprovalDt] [datetime] NOT NULL,
    [ScheduleEndDateDt] [datetime] NULL,
    [ProgrammeVenue] [varchar](250) NOT NULL,
    [NoofParticipants] [bigint] NOT NULL,
    [Remarks] [varchar](500) NOT NULL,
    [AccountsRemarks] [varchar](250) NOT NULL,
    [ExamDateDt] [datetime] NULL,
    [ProgrammeTitle] [varchar](250) NOT NULL,
    [DeletedFlg] [bit] NOT NULL
)

我正在向sql存储过程发送数据表。当我尝试从我的c＃传递此数据表时，它会显示异常 操作数类型碰撞：int与utblProgramAllotment不兼容这是用户定义的表类型

如果您要作为ad-hoc文本而不是专门作为存储过程执行传递执行存储过程的请求，那么参数顺序应该匹配：

exec uspInsertUpdateProgrammeAllotment @utblProgramAllotment, @UserId ,
                   @Message OUTPUT

或者您应该为参数命名：

exec uspInsertUpdateProgrammeAllotment @UserId = @UserId ,
                   @utblProgramAllotment = @utblProgramAllotment,
                   @Message = @Message OUTPUT

请参阅EXECUTE：

与@parameter_name=value form一起使用时，参数名称和常量不必按模块中定义的顺序提供。但是，如果@parameter_name=value形式用于任何参数，则必须将其用于所有后续参数。

和

如果未指定参数名称，则必须按模块中定义的顺序提供参数值。

操作数类型clash：int与utblProgramAllotment [用户定义的表类型]不兼容
