How to get the generated key for a column with lowercase characters from Oracle using JdbcTemplate (or plain JDBC)

Question

If I create a table like this:

create table standard (
    id NUMBER GENERATED by default on null as IDENTITY PRIMARY KEY, 
    text varchar2(200)
)

I can insert some data and get the generated id back with a method like this:

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 here is a NamedParameterJdbcTemplate, but since there are no parameters it should be equivalent to a similar call to JdbcTemplate.

But if I use a slightly different table with a lower case column name for the id:

create table lowercase (
    "id" NUMBER GENERATED by default on null as IDENTITY PRIMARY KEY, 
    text varchar2(200)
)

Passing the column name id fails:

Object insertAndReturnLowerCaseId() {
    GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
    template.update("insert into lowercase (text) values('test text')",new MapSqlParameterSource(), keyHolder, new String[]{"id"});

    return  keyHolder.getKey();
}

With (full call stack below)

PreparedStatementCallback; bad SQL grammar [insert into lowercase (text) values('test text')]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00904: "ID": invalid identifier

Passing the column name quoted "id" fails as well:

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();
}

With (full call stack below)

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

So: How do I get the generated value from an Oracle database when the id column is lower case? A solution based on the NamedParameterJdbcTemplate or the JdbcTemplate are preferred, but I take an answer based on plain JDBC just as well.

Answer 1

Starting in 21c, the Oracle JDBC thin driver supports double-quoted generated keys. The code snippet below works with the 21c and 23c drivers. With 19c it gives an error (Invalid argument(s) in call). Note that the lowercase table is the same as the one mentioned in the question.

String QUERY = "INSERT INTO lowercase (text) VALUES (?)";
try (PreparedStatement statement = conn.prepareStatement(QUERY, new String[] { "\"id\"" })) {
    statement.setString(1, "Foo");
    int affectedRows = statement.executeUpdate();
    assert (affectedRows==1);
    try (ResultSet keys = statement.getGeneratedKeys()) {
       assert(keys.next());
       System.out.println("keys.getLong(1)="+keys.getLong(1));
    }
      // omitted
}
