ORA-30337: multiple JOIN KEY clauses specified for the same parent level ORACLE 报错 故障修复 远程处理
文档解释
ORA-30337: multiple JOIN KEY clauses specified for the same parent level
Cause: Multiple JOIN KEY clauses were specified for a given parent level in a dimension hierarchy.
Action: Match up each JOIN KEY clause with the level it references in the hierarchy. Eliminate the redundant JOIN KEY clause.
ORA-30337错误是指在修改hierarchy关系时,用户使用了多个JOIN KEY子句来引用同一个父级。
官方解释
ORA-30337: multiple JOIN KEY clauses specified for the same parent level
Cause: The user specified more than one JOIN KEY clause for the same parent within a hierarchy.
Action: Remove all clauses but one from the SQL statement.
一般处理方法及步骤
1、检查SQL语句,查看是否有多个JOIN KEY子句用于引用同一个父级逻辑回引。
2、将语句中针对同一个父级的多个JOIN KEY子句删除,只保留一个父级对应的JOIN KEY子句。
3、执行更新或插入操作,检查是否还存在ORA-30337错误。
