ORA-32031: illegal reference of a query name in WITH clause
Cause: forward or recursive reference of a query name in WITH clause is not allowed.
Action: Correct query statement, then retry.
ORA-32031错误意味着在WITH子句中引用了一个非法的查询名称。
WITH myquery AS
(SELECT * FROM mytable WHERE some_column IN (SELECT some_other_column FROM anothertable))
SELECT * FROM myquery WHERE some_column
正常处理步骤及方法：首先，分析与此错误相关的SQL语句，并确认何处引用了查询名称。然后，将查询名称替换为对应的查询，这样就可以解决ORA-32031错误。例如：
WITH myquery AS
(SELECT * FROM mytable WHERE some_column IN (SELECT some_other_column FROM anothertable))
SELECT * FROM myquery WHERE some_column
(SELECT MIN(some_other_column) FROM mytable WHERE some_column IN (SELECT some_other_column FROM anothertable));
