问题描述
我使用以下代码使用 TADOStoredProc
类型
I use the following code to call my stored procedure using TADOStoredProc
type
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;
参数 @Error_Number
是存储过程 UpdateErrors
使用SQL Server Management Studio,我添加了用于确认的截图图像
The parameter @Error_Number
is part of the stored procedure UpdateErrors
using SQL Server Management Studio, I add snip image for confirmation
,但是我不明白为什么会出错
but I can't understand why I get an error
推荐答案
只需使用TADOCommand
Simply use a TADOCommand
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;
如果要修复代码
执行
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
等的方向。还有更多工作...使用ADOCommands做第一种方式
etc. Lots more work... do the first way with ADOCommands
