找不到存储过程的参数

I use the following code to call my stored procedure using TADOStoredProc type

我使用以下代码使用TADOStoredProc类型调用我的存储过程

MySP.Connection := aConnection;
MySP.ProcedureName := 'dbo.UpdateErrors';
MySP.Parameters.ParamByName('@Error_Number').value := -1;
MySP.Parameters.ParamByName('@NewError_Name').value := 'errorM1';
MySP.Parameters.Refresh;

MySP.ExecProc;

The parameter @Error_Number is part of the stored procedure UpdateErrors using SQL Server Management Studio, I add snip image for confirmation

参数@Error_Number是使用SQL Server Management Studio的存储过程UpdateErrors的一部分，我添加了剪辑图像以进行确认

but I can't understand why I get an error

但我不明白为什么我会收到错误

Simply use a TADOCommand

只需使用TADOCommand即可

  MyCommand.Connection := aConnection;
  MyCommand.CommandText := 'EXEC dbo.UpdateErrors :Er, :Na'; //you can call the params what you want
  MyCommand.Parameters[0].value := -1; //Or you can do ParamByNname and use Er and Na (or whatever you called your params) instead of indices
  MyCommand.Parameters[1].value := 'errorM1';
  MyCommand.Execute;

If you want to fix your code

如果要修复代码

做

 ErParam := MySP.Parameter.Add;
 ErParam.Name := '@Error_Number';
 ErParam.DataType := ftInteger; //put your correct type here
 ErParam.Direction := pdInput; //set your direction for the param

etc. Lots more work... do the first way with ADOCommands

还有更多的工作......用ADOCommands做第一种方式
