asp.net 메모리 프로세스 호출

1. 저장 프로세스를 호출하지만 되돌아오는 값이 없습니다

 
  
Private Function SqlProc1(ByVal ProcName As String) As Boolean 
  
'          , myConn      ProcName       
  
Dim myCommand As New SqlClient.SqlCommand(ProcName, myConn) 
  
With myCommand 
  
.CommandType = CommandType.StoredProcedure 
  
.Parameters.Add("@CodeType", SqlDbType.VarChar, 20).Value = "    " 
  
Try 
  
.ExecuteNonQuery() 
  
Return True 
  
Catch ex As Exception 
  
Return False 
  
End Try 
  
End Function 
  
 
 

2. 저장 프로세스를 호출하여 일반 값을 되돌려줍니다

 
  
Private Function SqlProc1(ByVal ProcName As String) As String 
  
'          , myConn      
  
Dim myCommand As New SqlClient.SqlCommand(ProcName, myConn) 
  
With myCommand 
  
.CommandType = CommandType.StoredProcedure 
  
.Parameters.Add("@CodeType", SqlDbType.VarChar, 20).Value = "    " 
  
.Parameters.Add("@NewCode", SqlDbType.VarChar, 20).Direction = ParameterDirection.Output 
  
Try 
  
.ExecuteNonQuery() 
  
Return .Parameters(1).Value() 
  
Catch ex As Exception 
  
Return "     " 
  
End Try 
  
End Function 
  
 
 

3. 저장 프로세스를 호출하여 데이터 집합을 되돌려줍니다
'VB.NET 코드

 
  
Private Function SqlProc2(ByVal ProcName As String, ByVal Param1 As String) As DataSet 
  
'      ，        
  
Dim myCommand As New SqlClient.SqlCommand 
  
myCommand.CommandType = CommandType.StoredProcedure 
  
myCommand.CommandText = ProcName 
  
myCommand.Connection = myConn 
  
'         ，      
  
Dim myDapter As New SqlClient.SqlDataAdapter(myCommand) 
  
myDapter.SelectCommand.Parameters.Add("@name", SqlDbType.VarChar, 20).Value = Param1 
  
'         ，       
  
Dim myDataSet As New DataSet 
  
Try 
  
myDapter.Fill(myDataSet) 
  
Catch ex As Exception 
  
End Try 
  
Return myDataSet 
  
End Function 
  
'       
  
Create Proc Test @name varchar(20) As 
  
Select * From EC_Grade where cGradeName=@name 
  
GO 
  
***             ,         
  
CREATE Proc Test 
  
@name varchar(200)='' 
  
--      200        ,          ;              
  
As 
  
Declare @sql1 varchar(8000) 
  
if @name<>'' 
  
Select @sql1='Select * From EC_Grade where '+ @name

Select @sql1='Select * From EC_Grade' 
  
exec(@sql1)
