53 from teacher
54 where job in('讲师','研发')
55 order by sal desc;
56 
57 --12、查询部门所有数据的insert语句
58 select 'insert into dept 
59 values('||deptno||','''||dname||''','''||loc||''');'
60 from dept;

基本查询

--子查询 查询的结果集当作另一个查询语句的表

--01、查询招生部所有男老师的姓名
select tname,deptno from teacher
where deptno = (select deptno from dept where dname = '招生部') 
and gendar='男';

--02、查询老师姓名和对应的部门名称
select tname ,(select dname from dept where dept.deptno = teacher.deptno) as dname
from teacher;

--03、查询在招生部以及人力部门的老师信息
select * from teacher 
where deptno in (select deptno from dept where dname in ('招生部','人力部'));

--SQL优化：使用exists代替in，使用not exists代替not in
--exists并不是返回一个结果集，而是返回true or false
select * from teacher 
where exists (select deptno from dept where deptno = teacher.deptno
 and dname in('招生部','人力部'));

子查询

--01、使用内连接查询招生部门所有男老师姓名
select tname,dname 
from teacher t inner join dept d
on t.deptno = d.deptno
where gendar = '男' and dname = '招生部';

--02、使用自连接查询老师的姓名和导师的姓名
select t1.tname 老师姓名,t2.tname 导师姓名
from teacher t1 , teacher t2
where t1.mgrno=t2.tno;

--03、使用左外连接查询老师的姓名，对应的导师姓名以及部门
select t1.tname 老师姓名,t2.tname 导师姓名,d.dname 部门名称
from teacher t1 left join teacher t2
on t1.mgrno = t2.tno
left join dept d
on t1.deptno = d.deptno;

--04、右外连接
select * from teacher t 
right join dept d 
on t.deptno = d.deptno;

连接查询

--01、substr()  字符串的截取  从第1个位置查询到第3个位置结束
SELECT SUBSTR('hello',1,3) FROM dual;
--从第一个位置查询之后的所有
SELECT SUBSTR('hello',1) FROM dual;

--02、instr() 查询字符在某个字符串中的下标！初始从1开始，没找到返回0
SELECT INSTR('world','r') FROM dual;

--03、to_char() 把日期转换成指定格式的字符串  hh24表示24小时制
SELECT to_char(SYSDATE,'yyyy-MM-dd hh24:mi:ss') FROM dual;

--04、to_date()把字符串转换成指定格式的日期
SELECT to_date('2017-06-14 20:28:45','yyyy-MM-dd hh24:mi:ss') FROM dual;

--05、nvl(e1,e2) e1代表列名，e2替换空的值
--如果e1为空则返回e2,如果不为空则返回当前值
SELECT NVL(mgrno,500) FROM teacher;

--06、nvl2(e1,e2,e3) 如果e1为空返回e3，e1不为空返回e2
SELECT NVL2(mgrno,10000,500) FROM teacher;

--07、decode(value,if1,then1,if2,then2...,else)
--如果value的值等于if1，返回then1,
--如果value的值等于if2，返回then2,
--如果value的值不等于任何if，返回else,
SELECT DECODE(mgrno,NULL,0,1008,5000,1) FROM teacher;

字符串、日期、条件函数

--查询总记录数 count(1)代替count(*)能提高查询效率
SELECT COUNT(1) FROM teacher;

--查询薪水总和
SELECT SUM(sal) FROM teacher;

--查询最高薪水
SELECT MAX(sal) FROM teacher;

--查询最低薪水
SELECT MIN(sal) FROM teacher;

--查询平均薪水
SELECT AVG(sal) FROM teacher;

--查询各个部门的编号，薪水（平均，最高，总和）
--按照部门的总薪水进行 降序排列
--部门人数在10人以上
SELECT deptno,AVG(sal),MAX(sal),SUM(sal)
FROM teacher
GROUP BY deptno
HAVING COUNT(deptno)>10
ORDER BY SUM(sal) DESC;

--查询部门编号为空的teacher人数
SELECT COUNT(1) FROM teacher 
WHERE deptno IS NULL;

聚合函数

--rank() 具有相等值的，排位相同，但是之后的排名跳跃
SELECT sal,tname,RANK() 
OVER(ORDER BY sal) 薪水排名
FROM teacher;

--dense_rank() 具有等值的，排位相同，之后的排名连续
SELECT sal,tname,dense_rank() 
OVER(ORDER BY sal) 薪水排名
FROM teacher;

--row_number() 不管值是否相等，排名都是连续的
SELECT sal,tname,
row_number() OVER(ORDER BY sal) 薪水排名
FROM teacher;

--查询各个部门（按照部门查询）的教师薪水，降序排列
--partition by deptno 按照部门进行分组
-- rank()/dense_rank()/row_number() 
-- over(partition by 分组字段 order by 排序字段 desc/asc)
SELECT deptno,tname,sal,
RANK() OVER(PARTITION BY deptno ORDER BY sal DESC) 薪水排名
FROM teacher;

分析函数

--union 并集(两个结果集中所有的数据) 重复数据显示一次
SELECT tno FROM teacher WHERE tno<1020
UNION
SELECT tno FROM teacher WHERE tno<1025;

--union all并集（两个结果集中所有的数据） 重复数据显示多次
SELECT tno FROM teacher WHERE tno<1020
UNION ALL
SELECT tno FROM teacher WHERE tno<1025;

--intersect 交集 (取两个结果集中公共的部分)
SELECT tno FROM teacher WHERE tno<1020
INTERSECT
SELECT tno FROM teacher WHERE tno<1025;

--补集 minus  eg:a>b,取a-b
SELECT tno FROM teacher WHERE tno<1025
MINUS
SELECT tno FROM teacher WHERE tno<1020;

--伪列：没有存储在真正的表中，但是可以在表中查询，不能进行增删改操作
--rowid:表中行的存储地址！A-Za-z0-9+/ 第二位变成B 以此类推
SELECT ROWID FROM teacher;
SELECT ROWID,tname FROM teacher
WHERE ROWID='AAASJgAAHAAAACVABJ';

--rownum:查询返回结果集中行的编号！可以作为分页使用
--rownum只能对=1或者<n进行操作！
--对于>n这种结果的查询：
--01、建立临时表
--02、让伪列rownum成为临时表中真正的列
--03、使用伪列的别名进行操作

--查询教师表中 ，薪水最高的前5名
SELECT tname,ROWNUM ,sal
FROM (SELECT * FROM teacher ORDER BY sal DESC) 
WHERE ROWNUM<6;

--查询教师表中薪水第5名的
SELECT * FROM 
(SELECT t.*,dense_rank()
OVER(ORDER BY t.sal DESC) ranks
FROM teacher t)
WHERE ranks=5;

--查询薪水在6-10名信息
--01、使用分析函数
SELECT * FROM 
(SELECT t.*,rank() 
OVER(ORDER BY sal DESC) ranks FROM teacher t)
WHERE ranks>5 AND ranks<11;
--02、三层嵌套
SELECT * FROM
(SELECT t.*,ROWNUM rw FROM
(SELECT * FROM teacher ORDER BY sal DESC) t)
WHERE rw>5 AND rw<11;

联合查询

--如果没有权限创建，使用sysdba授权
--grant create any view to 用户;

--创建或替换视图
CREATE OR REPLACE VIEW teacher_view
AS 
SELECT tname,sal FROM teacher;

--查询视图
SELECT * FROM teacher_view;

视图

--事务控制
INSERT INTO stuinfo VALUES(100,'小白1',100);
INSERT INTO stuinfo VALUES(200,'小白2',200);
SAVEPOINT a;--设置回滚点
INSERT INTO stuinfo VALUES(300,'小白3',300);
ROLLBACK TO SAVEPOINT a;--rollback到指定的回滚点
SELECT * FROM stuinfo;
ROLLBACK;--回滚到当前事务执行之前
SELECT * FROM stuinfo;
