java.sql.SQLException: 列名无效
java.sql.SQLException: Invalid column name
我不明白为什么我在这里得到 "Invalid column name"。
我们已经在 Oracle 中直接尝试了 sql 的一个变体，它工作正常，但是当我使用 jdbcTemplate 尝试它时出现了问题。
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();
});
在 Oracle 上运行的整个 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

你需要table定义来找出问题所在。安装 / 运行 Oracle SQL Developer（免费），设置 JDBC 连接并调查架构。
您需要检查是否存在以下列：
CFUSERENGINE51.PROCESSENGINE.applicationid,
CFUSERENGINE51.PROCESSENGINE.lastupdatetime
CFUSERENGINE51.PROCESSENGINE.phasecacheid
CFUSERENGINE51.PROCESSENGINE.processengineguid
CFUSERENGINE51.DATADOCUMENTXML.datadocumentid
CFUSERENGINE51.DATADOCUMENTXML.datadocumentxml
CFUSERENGINE51.DATADOCUMENTXML.processengineguid
问题不在于查询。查询 运行 没问题。
问题出在将行从 ResultSet 转换为域对象的 row-mapping 中。似乎作为应用程序中 row-mapping 的一部分，您正试图从 ResultSet 列中读取一个它不包含的值。
堆栈跟踪的关键行是靠近底部的以下三行：
at org.apache.commons.dbcp2.DelegatingResultSet.getString(DelegatingResultSet.java:267)
at no.gjensidige.bank.datavarehus.kontonrinfridd.Application.lambda$run[=10=](Application.java:69)
at org.springframework.jdbc.core.RowMapperResultSetExtractor.extractData(RowMapperResultSetExtractor.java:93)
这三行的中间部分似乎在您的代码中。 Application class 的第 69 行包含一个调用 ResultSet.getString() 的 lambda，但由于这会导致 'Invalid column name' 错误，因此 (a) 您正在传递一个字符串列名而不是数字列索引，并且 (b) 结果集中不存在您传递的列名。
既然您已经编辑了问题以包含对 jdbcTemplate.query() 的调用，尤其是负责将 result-set 行映射到对象的 lambda，问题就更清楚了。使用列名而不是索引调用 rs.getInt(...) 或 rs.getString(...) 时，不要包含 p. 或 x. 等前缀。不要写 rs.getInt("p.applicationid") 或 rs.getInt("x.datadocumentid")，写 rs.getInt("applicationid") 或 rs.getInt("datadocumentid").

在 oracle.jdbc.driver.GeneratedResultSet.getInt(GeneratedResultSet.java:1350)
在 com.zaxxer.hikari.pool.HikariProxyResultSet.getInt(HikariProxyResultSet.java)
当您尝试从结果集中获取的 index_name 不存在时也会出现此问题，请检查一次您的查询并与您尝试从结果集中获取的列索引名称相匹配。这可能是这个原因的可能性。
