注意：

每次登入sqlplus 時，會先執行$ORACLE_HOME/sqlplus/glogin.sql 或者當前目
錄的login.sql 指令碼。但是，會存在各種各樣的限制。在9i 或以下版本里，假如你
的腳本里有如下內容：
set sqlprompt "_connect_identifier >"
當第一次啟動並連線到資料庫DB1 時，提示資訊為：
DB1>
然後再連線到另外一個資料庫上：
DB1> connectscott/[email protected]
connected
DB1>
儘管連到了DB2，但提示資訊還是DB1。說明這個提示有問題。其實原因很
簡單，login.sql 只是在第一次啟動sqlplus 時執行，而在每次重新連線時不會執行。
所以提示資訊沒有變。
在10g 中，這種限制沒有了。指令碼不僅在啟動sqlplus 時執行，還會在每次連線數
據庫時也會執行：
DB1> connectscott/[email protected]
connected
DB2>
這樣資訊就是正確了。
