從3.4.2版本開(kāi)始，你可以像下面這樣使用：
publicString selectPersonSql() {returnnew SQL().SELECT("P.ID", "A.USERNAME", "A.PASSWORD", "P.FULL_NAME", "D.DEPARTMENT_NAME", "C.COMPANY_NAME").FROM("PERSON P", "ACCOUNT A").INNER_JOIN("DEPARTMENT D on D.ID = P.DEPARTMENT_ID", "COMPANY C on D.COMPANY_ID = C.ID").WHERE("P.ID = A.ID", "P.FULL_NAME like #{name}").ORDER_BY("P.ID", "P.FULL_NAME").toString();
}publicString insertPersonSql() {returnnew SQL().INSERT_INTO("PERSON").INTO_COLUMNS("ID", "FULL_NAME").INTO_VALUES("#{id}", "#{fullName}").toString();
}publicString updatePersonSql() {returnnew SQL().UPDATE("PERSON").SET("FULL_NAME = #{fullName}", "DATE_OF_BIRTH = #{dateOfBirth}").WHERE("ID = #{id}").toString();
}
