如果我创建一个这样的表：
create table standard (
id NUMBER GENERATED by default on null as IDENTITY PRIMARY KEY,
text varchar2(200)
)
我可以使用如下方法插入一些数据并取回生成的 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这是一个NamedParameterJdbcTemplate，但由于没有参数，它应该等效于对 . 的类似调用JdbcTemplate。
但是，如果我使用一个稍微不同的表，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();
}
使用（下面的完整调用堆栈）
PreparedStatementCallback; bad SQL grammar [insert into lowercase (text) values('test text')]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00904: "ID": invalid identifier
传递引用的列名"id"也会失败：
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();
}
使用（下面的完整调用堆栈）
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
那么：当 id 列是小写时，如何从 Oracle 数据库中获取生成的值？首选基于NamedParameterJdbcTemplate或 的解决方案JdbcTemplate，但我也采用基于普通 JDBC 的答案。
