文档解释
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。
官方解释
常见案例
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));
