動態關係運算符where子句是無效的（PL/SQL Oracle）的

我使用Oracle 10g和我有以下存儲過程：動態關係運算符where子句是無效的（PL/SQL Oracle）的

CREATE OR REPLACE PACKAGE BODY RF_PKG_STFCA_PositivePay

END RF_SP_STFCA_PositivePay; 
END RF_PKG_STFCA_PositivePay;

而進入到這個SQL時，我收到以下錯誤加：

無效的關係運算符

我想要做的事：我有這個存儲過程返回一個secordset使用REF CURSOR我的asp.net應用程序。我給它2個輸入參數。 1是日期（IN_DATE），1是運算符（IN_DATE_OPERATOR）。該程序工作如果「|| IN_DATE_OPERATOR ||」用=或> =取代我想要的方式。問題是基於.Net應用程序中發生的情況。我希望它在where子句中使用的操作符是「> =」或「=」，並且我不會知道哪些操作直到運行時。

我知道我在做這個錯誤，但我不知道如何獲得甲骨文重新認識，IN_DATE_OPERATOR是一個關係運算符。我打開其他方法有一個動態的運算符（我試過當IN_DATE_OPERATOR ='='THEN'='ELSE'> ='END也無濟於事），但我不想創建一個完整的獨立存儲過程I除了這個或者完全動態的where子句之外，還必須保養。我的理想解決方案將盡可能少地對此查詢進行更改。有什麼建議麼？

編輯：確定我已經編輯我的查詢做如下所示：

，但我得到了以下錯誤：

在您的編輯中，您正在添加字符串「IN_DATE」。注意，在我的例子中，我用綁定變量（'：1'和'：2'）替換它，然後在打開遊標時將'IN_DATE'作爲綁定變量值傳入。參數'IN_DATE'對於您正在構建的動態SQL語句不可見。當你在調試的時候，在'OPEN'之前添加一個'dbms_output.put_line（sql_statement）'可能是一個好主意。這將打印出您正在創建的SQL語句 - 然後，您可以直觀地檢查字符串是否有錯誤，或者手動運行以獲得更好的錯誤。 – 2012-04-04 20:04:16

對不起， '|| IN_DATE_OPERATOR || 'IN_DATE）' 應爲： '|| IN_DATE_OPERATOR || ''|| IN_DATE || '等 – Adamantine 2012-04-04 20:05:33

另外，您不想將'IN_DATE_OPERATOR'作爲綁定變量傳入。這實際上需要成爲你正在構建的SQL語句的一部分。看起來您正在構建SQL語句，您只需'USING'兩次指定'IN_DATE'（假設您在用綁定變量佔位符構建SQL語句時替換'IN_DATE'）。 – 2012-04-04 20:05:57

You w應該將SQL語句動態組裝到一個字符串中，然後使用該字符串打開遊標。您需要遵循以下get_cur過程，您需要在本地VARCHAR2變量（包括綁定變量的佔位符）中組裝SQL語句，然後使用您組裝的SQL語句和傳入的綁定變量打開遊標。

SQL> create or replace procedure get_cur(p_date in date, p_operator in varchar2, p_cur out sys_refcursor) 
    2 as 
    3 l_sql_stmt varchar2(1000); 
    4 begin 
    5 l_sql_stmt := 'select * from emp where hiredate ' || p_operator || ' :1'; 
    6 open p_cur for l_sql_stmt using p_date; 
    7 end;

這將如何與我目前的程序工作？它看起來像你建議我將整個查詢轉換成一個Varchar2，然後使用打開命令呢？我贊成你提供的代碼，但在使用我提供的代碼的工作示例中，包括局部變量，輸出curser等等（在這裏的工作比簡單的select語句更多），它會更有用。 – Adamantine 2012-04-04 18:48:19

@Adamantine - 更新我的答案，試圖構建你需要的字符串。有一個很好的機會，我沒有完全正確地構建它，因爲我不能真正測試它。 – 2012-04-04 19:02:03

是什麼「：=」do that「=」不行？ – Adamantine 2012-04-04 19:08:24
