PLS-00103：遇到符号“)”

Question

我正在创建一个需要连接到数据库并获取各种类型报告的类别的网络应用程序。在通过 java 中的存储过程执行我的 SQL 时，我遇到了一个奇怪的错误。 SELECT * FROM RPT_CTGR; 是我提交的 sql，但是当我查看堆栈跟踪时，它会返回如下：

 org.springframework.jdbc.BadSqlGrammarException: CallableStatementCallback; bad SQL grammar [{call SELECT * FROM RPT_CTGR;(?)}]; nested exception is java.sql.SQLException: ORA-06550: line 1, column 38:
PLS-00103: Encountered the symbol ")" when expecting one of the following:

   . ( * @ % & = - + < / > at in is mod remainder not rem
   <an exponent (**)> <> or != or ~= >= <= <> and or like like2
   like4 likec as between || indicator multiset member

由于某种原因，将额外的“（？）”附加到导致错误的语句末尾。有什么想法吗？

        Map results = proc.execute(params);
        List catagory = (List)results.get("catagories");
        //Test
        System.out.println(catagory.get(1).toString());
        return catagory;
    }



}

除了catagories.get(1).toString 之外，我的所有print 语句都能正确返回我提交的SQL

Answer 1

您应该在 Oracle 数据库中创建一个 Store Procedure 来执行您的 SELECT 语句。 您可以参考this question 来了解如何操作。

例如

CREATE OR REPLACE PROCEDURE getCatagories(categories in out sys_refcursor) is
  ...
  SELECT * FROM RPT_CTGR;
  ...

之后，您需要按名称调用存储过程。

public List search() {
  ...
  DataSource ds = (DriverManagerDataSource) ctx.getBean("dataSource");
  CataProc proc = new CataProc(ds,"getCatagories");
  Map results = proc.execute(params);
  List catagory = (List)results.get("catagories");
  ... 
}
