Java informix临时表的唯一id是什么？
我创建了一个临时表，它由几个带有Java informix临时表的唯一id是什么？,java,spring,informix,Java,Spring,Informix,我创建了一个临时表，它由几个带有UNION-ALL语句的表组成，如下所示。我希望稍后将此表映射到spring中的entity for repository。换句话说，我想在SpringJPA或hibernate中将临时表映射到实体 select * from name UNION ALL select * from soft where id >3 into temp namesoft_tmp 我尝试了以下方法 select * from namesoft_tmp 但我看不出
UNION-ALLselect * from name UNION ALL
select * from soft where id >3
into temp namesoft_tmp
select * from namesoft_tmp
如何基于唯一id执行select语句？***通常，UNION ALL查询的结果没有主键；不能保证结果集中没有重复的行 设想一个描述元素表的表，称为
元素SELECT * FROM elements WHERE atomic_number < 10
UNION ALL
SELECT * FROM elements WHERE symbol MATCHES '[A-F]*'
INTO TEMP union_all;

你能重新措辞你的问题吗？我不太明白您想要什么。您可以使用CREATEINDEX语句在临时表上创建索引。谢谢您的回复。在上面提到的查询中，我应该把createindex放在哪里？你能重新表述一下你的问题吗？我不太明白您想要什么。您可以使用CREATEINDEX语句在临时表上创建索引。谢谢您的回复。在上面提到的查询中，我应该在哪里创建索引？
