/*--处理要求
现在要统计全省工业企业指标情况，工业企业要分民营企业和国有企业两类，并且在统计出来时要求国有企业在民营企业的前边，要按照指标分类统计当月情况、和上月比较情况、指标提升情况、本年本月止累计、去年本月同期，指标提升情况要求当月指标减去上月指标，然后根据不同的指标情况得出是变好了还是变坏了，因为要求指标和单位都要按照事先规定的顺序显示，所以我设计了三个表，一个是企业名称表qiye，里边有企业名称、企业性质（用来区分是国企还是民营）、显示顺序（因为要求按照顺序显示和打印），一个是指标名称表zbmc，暂时里边有指标名、显示顺序，我想加个字段来表示指标提升情况的标记，比如说总产值增大后说明指标上升了，能耗升高后说明指标下降了，但我现在还没想出怎样定义这个字段，所以暂时用了个标记，它的值是1时表示 指标增到后说明指标是提升了，-1时表示该指标值增大后说明该指标下降了，最后一个表是具体指标资料表zhibiao，里边有企业名称、指标名称、年份、月份、当月指标数值
请问怎样用怎样的SQL语句才能得出如下格式的结果：假设是统计今年2月份数据
指标名称 单位名称 指标值 和上月比 指标提升情况 本年1－2月累计 去年同期值
