如何判断在传统ASP中使用ADO调用SQL Execute（）是否失败

Question

我有以下缩短的经典ASP代码，使SQL插入调用...

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

Set rs = cmd.Execute()

使用Execute（）返回的记录集如何判断插入是否成功？

Answer 1

检查Err对象

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

如果您不想检查错误，可以：

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

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

在同一个waw中，如果你有一个标识列，你可以使用获得结果id

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

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