Question

我在我的系统上安装了Oracle 12c，打算开发一些简单的表。如何创建可以创建和操作表的简单用户？现在，我可以访问dbms的唯一方法是使用sqlplus＆＃34; / as sysdba＆＃34;。

我创建了一个表空间。但是当我尝试使用该表空间创建一个默认的用户时，它告诉我表空间不存在。我运行＆＃34;从V $ tablespace＆＃34;中选择*我确实看到了我的表空间。

我觉得我在这里缺少一些基本的东西。我一直在阅读Oracle的文档，似乎没什么用。特别是，用户创建。 Oracle的示例导致我出错，抱怨可插拔数据库。阅读后，可插拔数据库是12c的新功能，因此您必须将C ##附加到前端用户名。我认为这使它成为一种常见的＆＃39;用户，虽然我不确定那是什么。无论如何，即使使用＆＃34; C ## test＆＃34;它无法找到我的表空间。 :-(

您需要在表空间中指定一些卷，以便用户创建表。如果你在cdb $ root：

loopCounter = 1
With DoCmd
    .SetWarnings False
    For Each Fil In fld.Files
            'I'm assuming the new field that will hold the FileName
            'doesn't exist as part of the original table so we
            'are going to create it for the first file read in
        If loopCounter = 1 Then CurrentDb.Execute ("Alter Table MyTable Add Column MyNewField Text")

        If UCase(Right(Fil.Name, 3)) = "CSV" Then
            .TransferText acImportDelim, , DestTable, Fil.Path, False
            CurrentDb.Execute ("Update MyTable Set MyNewField = '" & Fil.Name & "' where MyNewField is null")
        End If

        loopCounter = loopCounter + 1
    Next
    .SetWarnings True
End With
