MSSQL到Oracle

Question

我在转换这一系列的MSSQL时遇到了困难：

Union All 
Select 1,table_name,3,4,5,6,7,8 
from (select top 1 table_name 
      from information_schema.tables 
      order by 1) as subname 
order by 1 desc

到Oracle。

到目前为止，我有：

Union All 
Select 1,table_name,3,4,5,6,7,8 
from 
   (select * 
    from 
      (select table_name 
       from all_tables order by 1) 
    where rownum <= 1) as subname 
order by 1 desc

引发的错误是

  

ORA-00933：SQL命令未正确结束

任何帮助将不胜感激！

要在Oracle中命名子查询，请不要使用myDataSet = myWS.LookUp(sessionUserID, "UserID", "Users"); // Adapt this to the way you populate the dataset myDataTable = Tables["ProductTable"]; DataRow drCurrent =MyDataSet.Tables["ProductTable"].Rows[gridView1.GetFocusedDataSourceRowIndex()] myDataSet.AcceptChanges() drCurrent.Delete(); myWS.UpdateDB(myDataSet); 关键字。只需将名称直接放在括号后面。
