如何判斷在傳統ASP中使用ADO調用SQL Execute（）是否失敗

Question

我有以下縮短的經典ASP代碼，使SQL插入調用...

cmd.CommandText = "insert into MyTable values(blah, blah, blah)"   
cmd.CommandType = adCmdText

Set rs = cmd.Execute()

使用Execute（）返回的記錄集如何判斷插入是否成功？

Answer 1

檢查Err對象

cmd.CommandText = "insert into MyTable values(blah, blah, blah)"   
cmd.CommandType = adCmdText
On Error Resume Next
Set rs = cmd.Execute()
If Err.number<>0 or  objConnection.Errors.Count <> 0 Then
   'Do something to handle the error
End If
On Error Goto 0

如果您不想檢查錯誤，可以：

cmd.CommandText = "insert into MyTable values(blah, blah, blah) SELECT @@Rowcount"
cmd.CommandType = adCmdText

Set rs = cmd.Execute()
RecordsAffected = rs(0)

在同一個waw中，如果你有一個標識列，你可以使用獲得結果id

cmd.CommandText = "insert into MyTable values(blah, blah, blah) SELECT @@Identity"
cmd.CommandType = adCmdText

Set rs = cmd.Execute()
NewID = rs(0)
