我不明白为什么我得到“无效的列名称”在这里。java.sql.SQLException：无效的列名称
我们在Oracle中直接尝试过一种sql的变体，它工作正常，但是当我使用jdbcTemplate进行尝试时，出现了一些问题。
List<Dataholder> alleXmler = jdbcTemplate.query("select p.applicationid, x.datadocumentid, x.datadocumentxml " +
"from CFUSERENGINE51.PROCESSENGINE p " +
"left join CFUSERENGINE51.DATADOCUMENTXML x " +
"on p.processengineguid = x.processengineguid " +
"where x.datadocumentid = 'Disbursment' " +
"and p.phasecacheid = 'Disbursed' ",
(rs, rowNum) -> {
return Dataholder.builder()
.applicationid(rs.getInt("p.applicationid"))
.datadocumentId(rs.getInt("x.datadocumentid"))
.xml(lobHandler.getClobAsString(rs, "x.datadocumentxml"))
.build();
});
是在Oracle工作的整个SQL是这样的：
select
process.applicationid,
xml.datadocumentid,
xml.datadocumentxml
from CFUSERENGINE51.PROCESSENGINE process
left join CFUSERENGINE51.DATADOCUMENTXML xml
on process.processengineguid = xml. processengineguid
where xml.datadocumentid = 'Disbursment'
and process.phasecacheid = 'Disbursed'
and process.lastupdatetime > sysdate-14
整个堆栈跟踪：

您的表格是如何定义的？该变种如何直接在Oracle上尝试？请将它们添加到您的问题。 – Alfabravo
@Alfabravo我真的不知道。我收到了某人发来的这个数据库，他告诉我它直接在Oracle中运行。所以我知道它应该工作。但是“无效的列名”意味着它不是Oracle的错误，而是spring-jdbc自身。所以这应该是我认为很明显的事情。只是不在我:) –
所以你甚至没有无效列的名称？我们应该如何帮助你？ –
