动态关系运算符where子句是无效的（PL/SQL Oracle）的

我使用Oracle 10g和我有以下存储过程：动态关系运算符where子句是无效的（PL/SQL Oracle）的

CREATE OR REPLACE PACKAGE BODY RF_PKG_STFCA_PositivePay

END RF_SP_STFCA_PositivePay; 
END RF_PKG_STFCA_PositivePay;

而进入到这个SQL时，我收到以下错误加：

无效的关系运算符

我想要做的事：我有这个存储过程返回一个secordset使用REF CURSOR我的asp.net应用程序。我给它2个输入参数。 1是日期（IN_DATE），1是运算符（IN_DATE_OPERATOR）。该程序工作如果“|| IN_DATE_OPERATOR ||”用=或> =取代我想要的方式。问题是基于.Net应用程序中发生的情况。我希望它在where子句中使用的操作符是“> =”或“=”，并且我不会知道哪些操作直到运行时。

我知道我在做这个错误，但我不知道如何获得甲骨文重新认识，IN_DATE_OPERATOR是一个关系运算符。我打开其他方法有一个动态的运算符（我试过当IN_DATE_OPERATOR ='='THEN'='ELSE'> ='END也无济于事），但我不想创建一个完整的独立存储过程I除了这个或者完全动态的where子句之外，还必须保养。我的理想解决方案将尽可能少地对此查询进行更改。有什么建议么？

编辑：确定我已经编辑我的查询做如下所示：

    OPEN OUT_DATA FOR SQL_Statement USING IN_DATE, IN_DATE;

，但我得到了以下错误：

在您的编辑中，您正在添加字符串“IN_DATE”。注意，在我的例子中，我用绑定变量（'：1'和'：2'）替换它，然后在打开游标时将'IN_DATE'作为绑定变量值传入。参数'IN_DATE'对于您正在构建的动态SQL语句不可见。当你在调试的时候，在'OPEN'之前添加一个'dbms_output.put_line（sql_statement）'可能是一个好主意。这将打印出您正在创建的SQL语句 - 然后，您可以直观地检查字符串是否有错误，或者手动运行以获得更好的错误。 – 2012-04-04 20:04:16

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

另外，您不想将'IN_DATE_OPERATOR'作为绑定变量传入。这实际上需要成为你正在构建的SQL语句的一部分。看起来您正在构建SQL语句，您只需'USING'两次指定'IN_DATE'（假设您在用绑定变量占位符构建SQL语句时替换'IN_DATE'）。 – 2012-04-04 20:05:57

You w应该将SQL语句动态组装到一个字符串中，然后使用该字符串打开游标。您需要遵循以下get_cur过程，您需要在本地VARCHAR2变量（包括绑定变量的占位符）中组装SQL语句，然后使用您组装的SQL语句和传入的绑定变量打开游标。

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;

这将如何与我目前的程序工作？它看起来像你建议我将整个查询转换成一个Varchar2，然后使用打开命令呢？我赞成你提供的代码，但在使用我提供的代码的工作示例中，包括局部变量，输出curser等等（在这里的工作比简单的select语句更多），它会更有用。 – Adamantine 2012-04-04 18:48:19

@Adamantine - 更新我的答案，试图构建你需要的字符串。有一个很好的机会，我没有完全正确地构建它，因为我不能真正测试它。 – 2012-04-04 19:02:03

是什么“：=”do that“=”不行？ – Adamantine 2012-04-04 19:08:24
