c# - 如何从 VB.net(或 C#)调用 sql server 函数？有存储过程之类的语法吗？

Question

Public Sub cleanTables(ByVal prOKDel As Short)
     Dim sqlParams(1) As SqlParameter
     Dim sqlProcName As String
     sqlProcName = "db.dbo.sp_mySP"
     sqlParams(1) = New SqlParameter("@OKDel", prOKDel)
     Try
         dbConn.SetCommandTimeOut(0)
         dbConn.ExecuteNonQuery(CommandType.StoredProcedure, sqlProcName, sqlParams)
     Catch ex As Exception

     Finally

     End Try
End Sub

有没有

 CommandType.StoredProcedure...CommandType.Function
sqlParams(1) = New SqlParameter("@OKDel", prOKDel)...

最后是数据表 dt = dbConn.Execute(CommandType.StoredProcedure, sqlProcName, sqlParams)

谢谢

抱歉，没有办法直接运行函数。使用 sql 文本命令调用它

Public Sub RunFunction(ByVal input As Short)
            Using myConnection As New Data.SqlClient.SqlConnection
                Using myCommand As New Data.SqlClient.SqlCommand("Select dbo.MyFunction(@MyParam)", myConnection)
                    myCommand.CommandType = CommandType.Text
                    myCommand.Parameters.Add(New Data.SqlClient.SqlParameter("@MyParam", input))
                    myCommand.CommandTimeout = 0
                    Try
                        myCommand.ExecuteNonQuery()
                    Catch ex As Exception

                    End Try
                End Using

            End Using
        End Sub

或者在它周围包裹一个过程...

Create Procedure RunMyFunction(@MyParam as int)
Select * FROM dbo.MyFunction(@MyParam)
Go
