Oracle 查询出来的数据取第一条
select * from (select * from <table> order by <key>) where rownum=1;
select * from (select * from <table> order by <key> desc) where rownum=1;
sql如何查询表的第一条记录和最后一条记录
方法一:使用top
select TOP 1 * from apple;
select TOP 1 * from apple order by id desc;
(备注:top是Access的语法,MySQL不支持)
方法二:使用LIMIT
第一条记录
mysql> select * from apple LIMIT 1;
默认升序,等价于
mysql> select * from apple order by asc id LIMIT 1;
最后一条记录
mysql> select * from apple order by id desc LIMIT 1;
