标签:select class referer 开始 blog where http rom 读取
SELECT keyword FROM keyword_rank WHERE advertiserid=‘59‘ order by keyword LIMIT 2 OFFSET 1;
比如这个SQL ,limit后面跟的是2条数据,offset后面是从第1条开始读取
SELECT keyword FROM keyword_rank WHERE advertiserid=‘59‘ ORDER BY keyword LIMIT 2 ,1;
而这个SQL,limit后面是从第2条开始读,读取1条信息。
