我有一个包含多个函数的SEARCH包，每个包都返回一个pipelined表。
我收到以下错误：
ORA-29902: error in executing ODCIIndexStart() routine
ORA-06512: at "<SCHEMA_NAME>.SEARCH", line 955
ORA-06512: at "<SCHEMA_NAME>.SEARCH", line 216
ORA-06512: at line 1
ORA-06512: at "<SCHEMA_NAME>.SEARCH", line 1143
ORA-06512: at line 1
29902. 00000 - "error in executing ODCIIndexStart() routine"
*Cause: The execution of ODCIIndexStart routine caused an error.
*Action: Examine the error messages produced by the indextype code and
take appropriate action.
我用来获取此错误的命令是：
select * from table(search.user_search(10000003, '', 1, 20, 5, '', '', ''));

更改为= null。 is null也是错误的。
这些是一些明显的错误，但代码是如此复杂，我不确定它们是否与错误直接相关。您可能需要缩小代码，直到它可以放入一个小的，可重现的测试用例中。这有时可能需要数小时的工作。
另一个建议是重新考虑是否需要使用流水线功能。根据我的经验，流水线功能有缺陷和过度使用。有时它们可以被常规SQL语句替换。有时它们可以被更简单的函数替换，该函数返回完整的集合，而不是一次返回一行。除非集合是如此巨大以至于它无法合理地存储在内存中，或者您需要函数返回前N个结果以便可以立即处理它们，所以流水线功能无助于此。
