如果我创建这样的表：
create table standard (
id NUMBER GENERATED by default on null as IDENTITY PRIMARY KEY,
text varchar2(200)
)
我可以插入一些数据，并使用类似的方法获取生成的ID：
Object insertAndReturnStandardId() {
GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
template.update("insert into standard (text) values('test text')",new MapSqlParameterSource(), keyHolder, new String[]{"id"});
return keyHolder.getKey();
}
[template这里是NamedParameterJdbcTemplate，但是由于没有参数，因此它应该等效于对JdbcTemplate的调用。
但是，如果我使用一个稍有不同的表，其ID的列名称为小写：
create table lowercase (
"id" NUMBER GENERATED by default on null as IDENTITY PRIMARY KEY,
text varchar2(200)
)
传递列名id失败：
Object insertAndReturnLowerCaseId() {
GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
template.update("insert into lowercase (text) values('test text')",new MapSqlParameterSource(), keyHolder, new String[]{"id"});
return keyHolder.getKey();
}
具有（下面是完整的调用堆栈）
PreparedStatementCallback; bad SQL grammar [insert into lowercase (text) values('test text')]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00904: "ID": invalid identifier
传递引用名"id"的列名也失败：
private Object insertAndReturnLowerCaseId() {
GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
template.update("insert into lowercase (text) values('test text')",new MapSqlParameterSource(), keyHolder, new String[]{"\"id\""});
return keyHolder.getKey();
}
具有（下面是完整的调用堆栈）
PreparedStatementCallback; uncategorized SQLException for SQL [insert into lowercase (text) values('test text')]; SQL state [99999]; error code [17068]; Invalid argument(s) in call; nested exception is java.sql.SQLException: Invalid argument(s) in call
因此：当id列为小写字母时，如何从Oracle数据库获取生成的值？首选基于NamedParameterJdbcTemplate或JdbcTemplate的解决方案，但我也基于普通JDBC给出了答案。
