如何把代码中的SQL语句改成可以直接在数据库中运行的SQL语句

主要是时间，时间，时间！
首先，你要有项目中的一段SQL代码（这里是mybatis中的）：

select * from news where news_status=true and department_id = #{departmentId,jdbcType=VARCHAR} and news_type = #{newsType,jdbcType=VARCHAR} and classes_id = #{classesId,jdbcType=VARCHAR} and ( news_date between #{startDate,jdbcType=DATE} and #{endDate,jdbcType=DATE} ) <if test="createDate != null"> and create_date = #{newsDate,jdbcType=DATE} </if> order by news_date,news_time,news_time_quantum asc,update_date desc

改写后的SQL

select * from news where news_status=true and department_id = '132433' and news_type = '摄影' and classes_id = '201506' and ( news_date between to_date('2015-10-20', 'yyyy-MM-dd') and to_date('2015-11-16', 'yyyy-MM-dd') ) and create_date = to_date('2015-10-16', 'yyyy-MM-dd') order by news_date,news_time,news_time_quantum asc,update_date desc
