有人可以通過查詢獲取包含Oracle 7數據的創建表腳本嗎？由於這是Oracle 7，並且在一個非常老的Linux機器上，我不認爲蟾蜍會工作。我必須使用putty連接到服務器，然後從中啓動sqlplus。一切都是膩子窗口。請幫忙。感謝生成包含Oracle 7數據的表格腳本

如何：
create table test(id number, data varchar2(100));
insert into test values (1, 'This isn''t the data you''re looking for');
應該在Oracle 7環境下運行，但它是未經檢驗的，因爲我還沒有在十年或更長時間訪問Oracle 7環境。
要找出當前存在的表的結構，您可以使用SQL * Plus describe命令。例如：
SQL> desc dual
Name Null Type
----- ---- -----------
DUMMY VARCHAR2(1)
哪個應該給你足夠的信息來在另一個環境中重新創建表本身。此外，您可以查詢[ALL | USER] _CONSTRAINTS，[ALL | USER] _CONS_COLUMNS，[ALL | USER] _INDEXES和[ALL | USER] _TRIGGERS以確定任何其他相關信息（假設這些視圖存在後兩個可能不存在）。
最後，您可以構建一個查詢或進程，提取數據並將其後臺處理或使用UTL_FILE將其以適合插入的格式寫入文件。

我有一個表已經存在於數據庫中，但現在我想將它移動到MS SQL。但作爲一個非常舊的Linux機器上運行的Oracle 7，我不能使用蟾蜍或SQL開發人員點擊它並說出口。我只是想知道是否有一種方法可以將一個腳本的所有數據都轉換爲一個文件，這樣我就可以將它導入到sql server中。就像當你右鍵點擊一張桌子並且用數據生成腳本一樣。 – user3731575

您可以嘗試導出您的Oracle 7數據庫並將其導入到您應該能夠創建遷移腳本的Oracle 10g XE數據庫。
看到這裏http://docs.oracle.com/cd/B14117_01/server.101/b10763/expimp.htm#sthref707

我有一個腳本年前寫的，它應該在Oracle 7.它不是一個簡單的查詢，它創建了一個包和一個工作表中，但它可以幫助

是的，你說得對。我評論一下。該命令修剪文件輸出的尾部空格，這不是必需的。 –
