ORA-19036: Invalid query result set in newContextFromHierarchy()
Cause: The result set of the query used in the newContextFromHierarchy() does not have the same property as the result set generated by a CONNECT BY query.
Action: Make sure the query used in newContextFromHierarchy() is a CONNECT BY query or the query returns the result set have the same property as the result set generated by a CONNECT BY query.
ORA-19036 错误通常是由于传入 newContextFromHierarchy() 函数的查询结果集对象不是正确的类型所导致的。
ORA-19036: Invalid query result set in newContextFromHierarchy()
newContextFromHierarchy() 的调用传入了无效的查询结果集。每个实现DBMS_OLAP包的子程序都只支持正确的查询结果集对象。
ORA-19036将发生在DBMS_OLAP包子程序中,例如,当使用不正确的查询结果集对象调用newContextFromHierarchy()函数时,将发生此错误。
要解决ORA-19036错误,可以根据上文中官方解释的提示,检查传入newContextFromHierarchy()函数的查询结果集对象,确保是正确的类型,然后重新运行调用这个数据库函数的查询和处理过程。
