它可能会回应谁，我们想在 11g r2 Oracle DBMS 上使用带有 PIVOT 选项的 SELECT 函数。我们的查询是这样的：

select * from
(SELECT o.ship_to_customer_no, ol.item_no,ol.amount
  FROM t_order o, t_order_line ol
 WHERE o.NO = ol.order_no and ol.item_no in (select distinct(item_no) from t_order_line))
  pivot --xml 
(  SUM(amount) FOR item_no IN ( select distinct(item_no) as item_no_ from t_order_line));

可以看出，XML 被注释掉了，如果作为 PIVOT XML 运行，它会以 XML 格式给出正确的输出，但是我们需要将数据作为未格式化的数据透视数据，但是这句话会抛出错误： ORA-00936: missing expression

欢迎任何决议或想法，

此致

我现在没有可用的 Oracle 11 实例（PIVOT在 Oracle 11 中是新实例），所以我只能推测。我的猜测是，--在. 您是否尝试过用而不是放在它前面来评论它？ pivotpivotxml/**/--

例如，如果您从 Java 运行此查询，那么如果您尝试在以下字符串中运行 SQL，我希望您会收到“缺少表达式”错误：

String sql =
  "select * from (SELECT o.ship_to_customer_no, ol.item_no,ol.amount " +
  "FROM t_order o, t_order_line ol " +
  "WHERE o.NO = ol.order_no and ol.item_no in (select distinct(item_no) from t_order_line)) " + 
  "pivot --xml " +
  "( SUM(amount) FOR item_no IN ( select distinct(item_no) as item_no_ from t_order_line))";

因为这个 SQL 字符串被连接成一行，所以--前面的xml会导致 Oracle 忽略它后面的查询中的所有内容。

编辑：在您添加的程序中，我关心的是这部分（缩写）：

v_sql := 'begin
           select * from ...;
          end;';

open DENEME for
select v_sql from dual;

我不明白你为什么使用BEGINand 。尝试删除它们。ENDv_sql

另外，请注意不要在 SQL 语句字符串中留下分号。ORA-00911: invalid character如果您尝试使用 EXECUTE IMMEDIATE 或类似方式运行它，以下将给出错误：

v_sql := 'select * from dual;'; /* note the semicolon inside the string */

但以下将是好的：

v_sql := 'select * from dual';

最后，您似乎希望返回此 SQL 查询的结果，而不是查询本身作为字符串。用以下内容替换您的open DENEME for ...语句应该可以满足您的要求：

open DENEME for v_sql;

编辑 2：在您的过程中，有一个对 DBMS_OUTPUT.PUT_LINE 的注释调用。你验证过这里生成的SQL是正确的吗？特别是，您确定没有用于形成v_query_items和v_pivot_items包含'字符的值吗？

PIVOT使用动态 SQL可能存在问题。我不知道，也无能为力，因为我在这里无法访问 Oracle 11。如果您将 SQL 简化为一个小得多的查询，但仍然有一个查询，您是否仍然会遇到错误PIVOT？换句话说，找到一个简单的PIVOT查询（例如，你可以在 SQL Developer 中成功运行它或类似的东西），编写一个如下所示的过程，看看你是否从中得到任何数据：

CREATE OR REPLACE PROCEDURE dynamic_pivot_test(
  results OUT SYS_REFCURSOR
)
AS
BEGIN
  OPEN results FOR 'SELECT ...'; /* put the PIVOT query here. */
END;

2011 年 1 月 17 日编辑的过程很脏但可以工作，循环游标应该改变，更好的错误。处理动态 sql（目前首屈一指），将在有时间时尝试改进它。谢谢大家的帮助。
