如何在 jOOQ 中使用别名

SelectSelectStep<Record3<String, String, String>> select = create.select(
    AUTHOR.as("a").FIRST_NAME.as("fn"),
    AUTHOR.as("a").LAST_NAME.as("ln"),
    AUTHOR.as("a").DATE_OF_BIRTH
).from(AUTHOR.as("a"));

Table<Record> t = create.select(
    AUTHOR.FIRST_NAME,
    AUTHOR.LAST_NAME,
    AUTHOR.DATE_OF_BIRTH
).from(AUTHOR).asTable("t");

Field<String> fn = field(AUTHOR.FIRST_NAME, "fn");
