shell腳本中的意外錯誤：「來自`的意外關鍵字`」。找不到錯誤

我寫了一個shell腳本，它將連接數據庫並檢索記錄。但是，當我超出它，它給了我錯誤：意外的關鍵字from。任何人都可以請建議我我在做什麼錯誤？我做的代碼下面給出：shell腳本中的意外錯誤：「來自`的意外關鍵字`」。找不到錯誤

粘貼你的腳本http://shellcheck.net/會很有幫助表明了錯誤的根源，但實際的錯誤信息不完全坦誠。 – tripleee

我編輯了似乎是明顯的複製/粘貼錯誤。請檢查編輯以確保我沒有刪除任何重要內容。 – tripleee

我希望http://shellcheck.net/也會警告明確檢查'$？'，或者在同一個目錄下執行'cd'超過次數。但這些主要是文體問題。 – tripleee

我認爲你需要把你的sqlplus命令所有在一行

DBRESULT=`sqlplus sprint2/[email protected] select * from mytable where productcode='10130' AND taccode='35710100'; quit;`

或包括顯式換行符

DBRESULT=`sqlplus sprint2/[email protected] \ 
    select * from mytable where productcode='10130' AND taccode='35710100'; \ 
    quit;`

此外，您需要用反斜槓或（更好地）引用SQL來正確地引用'*'。另外，還有一個很好的理由，'$（command）'強烈建議'''命令\''。 – tripleee

Oracle sqlplus不支持內聯sql語句。它唯一的命令行支持是使用@運行一個sql腳本。解決您的問題的可行方案是使用heredoc。

你可以這樣做：

DBRESULT=$(sqlplus sprint2/[email protected] <<-SQL 
    select * from mytable where productcode='10130' AND taccode='35710100'; 
    exit; 
SQL

不錯的建議。代碼正在工作。您能否告訴我是否有任何方法可以建立持久性數據庫連接。觸發多個查詢，然後關閉連接？ – user286009

有一種方法使用2個管道。它比你期望的簡單和容易。 – alvits
