SQL必知必会学习笔记

2.5  select

SELECT       要返回的列或表达式     是
FROM          从中检索数据的表        仅在从表选择数据时使用
where        行级过滤                      否
group by  分组说明                      仅在按组计算聚集时使用
having        组级过滤                      否
order by  输出排序顺序               否

SELECT DISTINCT vend_id, prod_price --会列出二列数据不相同每行不同的数据
FROM Products;

3.1排序

SELECT prod_id, prod_price, prod_name
FROM Products
ORDER BY prod_price, prod_name;   --排序 先排prod_price顺序,然后在其基础上排prod_name

SELECT prod_id, prod_price, prod_name
FROM Products
ORDER BY 3, 2;  --先排第3列,在其基础上排第2列

SELECT prod_id, prod_price, prod_name
FROM Products
ORDER BY  prod_name DESC,prod_price DESC; --DESC是反转,先排前面的,再排后面的

4.1where

排序ORDER BY应该在where之后

where的字段不是一定要在select里出现的

''单引号用来限定字符串,与数值

区分大小写查询时应在字段后面加入'collate Chinese_PRC_CS_AS'     如where str collate Chinese_PRC_CS_AS ='i'

<>	!=	不等于 注:Access支持<>不支持!=
!		不(非) 不可单用,用于组合
>=		大于等于
BETWEEN		在指定的两个值之间
IS NULL		为NULL值 (NULL表示无值的意思)

SELECT prod_name, prod_price
FROM Products
WHERE prod_price BETWEEN 5 AND 10; --在二者之间

SELECT cust_name FROM CUSTOMERS
WHERE cust_email IS NULL; --显示其列cust_email为空的 cust_name

5.1逻辑操作符

and 满足二个子句

or   满足其中一个

SELECT prod_name, prod_price FROM Products
WHERE vend_id = 'DLL01' OR vend_id = 'BRS01' AND prod_price >= 10;--SQL（像多数语言一样）在处理OR操作符前，优先处理AND操作符
--等价于vend_id = 'DLL01' OR (vend_id = 'BRS01' AND prod_price >= 10)

所以如果想先OR 应该在or二个条件加括号

IN操作符 指定条件范围 (注in比or操作更快)

SELECT prod_name, prod_price FROM Products
WHERE vend_id IN ( 'DLL01', 'BRS01' ) ORDER BY prod_name;--显示包含了'DLL01', 'BRS01'的

NOT操作符 排除

SELECT prod_name FROM Products
WHERE NOT vend_id = 'DLL01' ORDER BY prod_name;--除去'DLL01' 的所有都显示出来

6.1 LIKE操作符

多个通配符%  任何字符出现任意次数 (注 Access需要使用*)  不匹配null

SELECT prod_id, prod_name FROM Products 
WHERE prod_name LIKE 'Fish%';  --开头为Fish的

单个通配符_  匹配单个字符            (注 Access需要使用?)  不匹配null  语法和%一样

[]通配符  匹配一个字符,内容为方括号内的

SELECT cust_contact FROM Customers
WHERE cust_contact LIKE '[JM]%'  --匹配J或M开头的cust_contact

7.2计算字段

拼接字段

SELECT vend_name + ' (' + vend_country + ')' FROM Vendors ORDER BY vend_name;--拼接vend_name与end_country字段

RTRIM()删除右边的空格  LTRIM()删除左边的空格 trim()删除左右二边的空格

SELECT RTRIM(vend_name) + ' (' + RTRIM(vend_country) + ')' FROM Vendors ORDER BY vend_name;--删除右边的空格再合并

AS 显示别名

SELECT vend_name  AS vend_title FROM Vendors --用vend_title别名显示结果

执行算术运算

SELECT prod_id, quantity, item_price, 
quantity*item_price AS expanded_price --把查询到的quantity与item_price字段的结果相乘用expanded_price显示
FROM OrderItems  WHERE order_num = 20008;

8.1函数

函数	说明		函数	说明
LEFT(字段名,2)	返回字符串左边的2个字符	相反	RIGHT(字段名,2)	返回字符串右边的2个字符
LOWER() Access使用LCASE()	将字符串转换为小写		UPPER() Access使用UCASE()	将字符串转换为大写
LTRIM()	去掉字符串左边的空格		RTRIM()	去掉字符串右边的空格
Soundex()	返回字符串的SOUNDEX值 主要用于英语读法相似的(略过)		length()	返回字符串的长度

日期处理函数

SELECT order_num,order_date FROM Orders
WHERE DATEPART(yy, order_date) = 2012; --表示字段order_date的年份为2012年的
--DATEPART(M, order_date)如果是M则表示月份是5月,d为日,H为时,mm为分,ss为秒

数值处理函数

ABS()	绝对值	PI()	圆周率	SQRT()	平方根	EXP()	指数值
COS()	角度余弦	SIN()	角度正弦	TAN()	角度正切

9.1聚集函数

AVG()	平均值	COUNT()	计数(共几行)	MAX()	最大值	MIN()	最小值
SUM()	总计(和运算)

9.3组合聚集函数

SELECT COUNT(*) AS num_items,
       MIN(prod_price) AS price_min,
       MAX(prod_price) AS price_max,
       AVG(prod_price) AS price_avg
FROM Products;

10.2分组与过滤

SELECT order_num, COUNT(*) AS items
FROM OrderItems
GROUP BY order_num     --这里按order_num分组
HAVING COUNT(*) >= 3   --这里给分组过滤,显示分组大于3的
ORDER BY items, order_num;   --排序方式,可以理解为对结果的排序处理

11 使用子查询

先得到子句的结果再去查询 (注意嵌套子查询只能单列(多列将返回错误))

SELECT cust_name, cust_contact
FROM Customers
WHERE cust_id IN (SELECT cust_id
                  FROM Order
                  WHERE order_num IN (SELECT order_num
                                      FROM OrderItems
                                      WHERE prod_id = 'RGAN01'));

先得到父句的结果再去查询子句

SELECT cust_name, 
       cust_state,
       (SELECT COUNT(*) 
        FROM Orders 
        WHERE Orders.cust_id = Customers.cust_id) AS orders --这里的子句用结果中的Customers.cust_id为条件去查询(只能返回一个)
FROM Customers 
ORDER BY cust_name;

12 联结

SELECT vend_name, prod_name, prod_price
FROM Vendors, Products
WHERE Vendors.vend_id = Products.vend_id;  --内部相同的联结,不相同的不显示

多表联结,则使用and

SELECT cust_name, cust_contact FROM Customers, Orders, OrderItems
WHERE Customers.cust_id = Orders.cust_id AND OrderItems.order_num = Orders.order_num AND prod_id = 'RGAN01';

自联结

找Jim Jones的公司的所有记录

SELECT c1.cust_id, c1.cust_name, c1.cust_contact
FROM Customers AS c1, Customers AS c2
WHERE c1.cust_name = c2.cust_name   --找c1表内与c2结果列名cust_name一样的的记录
 AND c2.cust_contact = 'Jim Jones'; --先找到jim Jones那一行,得到c2表的一行

外连接

左联接 LEFT OUTER JOIN

SELECT Customers.cust_id, Orders.order_num
FROM Customers LEFT OUTER JOIN Orders ---以左边的表为基础显示结果
 ON Customers.cust_id = Orders.cust_id;

右联接 RIGHT OUTER JOIN

SELECT Customers.cust_id, Orders.order_num
FROM Customers RIGHT OUTER JOIN Orders --右边表为基础显示结果
 ON Orders.cust_id = Customers.cust_id;

全联接 FULL OUTER JOIN

SELECT Customers.cust_id, Orders.order_num
FROM Orders FULL OUTER JOIN Customers --显示比二个表为基础的结果
ON Orders.cust_id = Customers.cust_id;

左连接并分组计算

SELECT Customers.cust_id,
       COUNT(Orders.order_num) AS num_ord
FROM Customers LEFT OUTER JOIN Orders
 ON Customers.cust_id = Orders.cust_id
GROUP BY Customers.cust_id;

组合查询UNION (二个结果同一行会被自动取消) (合并结果,二个查询结果的字段要一致,类型能隐式转换)

SELECT cust_name, cust_contact, cust_email
FROM Customers
WHERE cust_state IN ('IL','IN','MI')
UNION -- 这里改成UNION ALL则显示二个查询的集合,不会自动取消同一行
SELECT cust_name, cust_contact, cust_email
FROM Customers
WHERE cust_name = 'Fun4All';

15 数据插入

插入检索出来的数据

INSERT INTO Customers
(cust_id,cust_contact,cust_email,cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country)
SELECT --从CustNew检索出的结果插入到Customers表中,插入时主要为列的顺序,非字段名
 cust_id,cust_contact,cust_email,cust_name,cust_address,cust_city,cust_state,cust_zip,cust_country
FROM CustNew;

复制新表

SELECT * --所有列,如果只是部分,应指定列名
INTO CustCopy  --新的表名
FROM Customers;

16 更新数据

UPDATE Customers
SET cust_contact = 'Sam Roberts',
    cust_email = 'sam@toyland.com'  --也可以直接设置为null, cust_email = NULL
WHERE cust_id = '1000000006'; --更新时一定要注意过滤,不然所有行都会更新掉

删除数据  注!删除前最好使用select检索结果,看where是否有错

DELETE FROM Customers
WHERE cust_id = '1000000006';

17创建表

CREATE TABLE OrderItems
(
    order_num      INTEGER          NOT NULL,  --不能为空值,不允许NULL值
    order_item     INTEGER           NULL,   --表示可以为空值
    prod_id        CHAR(10)         NOT NULL,
    quantity       INTEGER          NOT NULL      DEFAULT 1,  --默认值为1
    item_price     DECIMAL(8,2)     --省略NOT NULL时,默认可以为空l
);

GO
--判断非空的写法WHERE 字段 IS NULL
SET ANSI_NULLS ON
GO
--标识符可以由双引号分隔,文字必须由单引号分隔
SET QUOTED_IDENTIFIER ON
GO
--允许空值的Char(n)和binary(n)列填充到列长
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[Pc_ADAccount]
(
[F_Id] [varchar](50) NOT NULL,
[F_Account] [varchar](50) NULL,
[F_AccountName] [varchar](50) NULL,
[F_EmpId] [varchar](50) NULL,
[F_PublicAccount] [bit] NULL,
[F_RestrictLogOnPC] [varchar](50) NULL,
--为多个键定义约束(PK_SYS_ADAccount为) asc升序NONCLUSTERED非聚集索引
CONSTRAINT [PK_Pc_ADAccount] PRIMARY KEY NONCLUSTERED 
(
    [F_Id] ASC
)WITH (PAD_INDEX  = OFF, 
STATISTICS_NORECOMPUTE  = OFF, 
IGNORE_DUP_KEY = OFF, 
ALLOW_ROW_LOCKS  = ON, 
ALLOW_PAGE_LOCKS  = ON
) ON [PRIMARY]
) ON [PRIMARY]

GETDATE()系统时间

慎用下面命令

添加一列

ALTER TABLE Vendors
ADD vend_phone CHAR(20)

移除一列

ALTER TABLE Vendors
DROP COLUMN vend_phone;

修改列类型

ALTER TABLE EmployeeInfo 
ALTER COLUMN Employee_number NVARCHAR(Max)

修改列的字段名

exec sp_rename '表名.原列名','新列名','column';

删除表

DROP TABLE CustCopy;--可以使用关系规则防止意外删除

SQL Server用户使用sp_rename存储过程重命名表

18视图

CREATE VIEW CustomerEMailList AS  --创建视图,创建一个cust_email不为空的表,查询时和表格一样操作
SELECT cust_id, cust_name, cust_email
FROM Customers
WHERE cust_email IS NOT NULL;

19执行存储过程

EXECUTE AddNewProduct( 'JTS01', 'Stuffed Eiffel Tower',6.49,'Plush stuffed toy with the text La Tour Eiffel in red white and blue' );
--执行存储过程,其参数有多个

创建存储过程

CREATE PROCEDURE NewOrder 
@cust_id CHAR(10) 
AS
SET NOCOUNT OFF -- 显示受影响的行数
DECLARE @order_num INTEGER  -- 为订单编号声明变量 在上面没有变量时,可自己定义变量
SELECT @order_num=MAX(order_num)-- 获取当前最高订单号
FROM Orders
SELECT @order_num=@order_num+1 -- 确定下一个订单号
INSERT INTO Orders(order_num, order_date, cust_id) -- 插入新的秩序
VALUES(@order_num, GETDATE(), @cust_id)
RETURN @order_num;-- 返回的订单号

存储过程的输写格式

create proc testpray
@prayname char(8)
as 
declare @_id int
select @_id =COUNT(id)+1 from test
insert into test(id,name)values(@_id,@prayname)
return 1
--下面是测试显示
declare @str int
 exec @str = testpray artre
select @str

20管理事务处理

相关知识点

注意:书本的实例测试时,部分有问题,这里请查询网上相关资料为准

事务管理

BEGIN TRAN  --开始事务
INSERT INTO Customers(cust_id, cust_name)VALUES('1000000017', 'Toys Emporium'); 
INSERT INTO Customers(cust_id, cust_name)VALUES('1000000010', 'Toys Emporium');
if @@ERROR <> 0 Rollback tran;  --ERROR为SQL函数,出错时ERROR不为零,意在上面的操作中有错误时回滚事务
COMMIT TRAN --这是提交事务,可以理解为,之前BEGIN TRAN之后的一系列操作还没保存!在时才会保存到源数据里
select * from Customers

事务保存点

begin Tran;  --这是TRANSACTION的缩写 在begin Tran这后总有一个ROLLBACK Tran回滚事务或commit tran执行事务,
save tran test_1; --保存点test_1
DELETE FROM CustNew where cust_id = '1000000002';
save tran test_2;  --保存点test_2
DELETE FROM CustNew where cust_id = '1000000003';
ROLLBACK Tran test_1; --回滚至保存点test_2 ,
--commit tran;  --提交事务,事务的结束,如果没设置自动结束,事务会占用资源,无法查询
select * from CustNew;

21游标

游标很少用于ASP等 参考资料

DECLARE CustCursor CURSOR ----声明时未指定"local"或"global"关键字,系统默认游标是"global(全局)"的.
FOR SELECT * FROM Customers WHERE cust_email IS NULL
OPEN CustCursor  --在open时,执行查询,存储检索出的数据以供浏览和滚动.
FETCH NEXT FROM CustCursor --读取游标数据,其中的NEXT为下一行记录,详见附2,这里可以执行 单语句运行
CLOSE CustCursor; --关闭游标
Deallocate CustCursor; --释放游标
/*
附1:标准游标:Declare MyCursor Cursor For Select * From Master_Goods
    只读游标:Declare MyCusror Cursor For Select * From Master_Goods For Read Only
    可更新游标:Declare MyCusror Cursor For Select * From Master_Goods For UpDate

附2:Next表示返回结果集中当前行的下一行记录，如果第一次读取则返回第一行。默认的读取选项为Next
    Prior表示返回结果集中当前行的前一行记录，如果第一次读取则没有行返回，并且把游标置于第一行之前。
    First表示返回结果集中的第一行，并且将其作为当前行。
    Last表示返回结果集中的最后一行，并且将其作为当前行。
    Absolute　n　如果n为正数，则返回从游标头开始的第n行，并且返回行变成新的当前行。如果n为负，则返回从游标末尾开始的第n行，并且返回行为新的当前行，如果n为0，则返回当前行。
    Relative　n　如果n为正数，则返回从当前行开始的第n行，如果n为负,则返回从当前行之前的第n行，如果为0，则返回当前行。
*/

22约束

CREATE TABLE Vendors (
  vend_id         CHAR(10)       NOT NULL    PRIMARY KEY, --Primary key设置为主键
  vend_name       CHAR(50)       NOT NULL,
  )

ALTER TABLE Vendors  --修改列
ADD CONSTRAINT PRIMARY KEY (vend_id);--改为主键 使用的是Constraintd 强迫

外键

CREATE TABLE Orders
(
    order_num     INTEGER     NOT NULL PRIMARY KEY,
    order_date    DATETIME    NOT NULL,
    cust_id       CHAR(10)    NOT NULL REFERENCES Customers(cust_id) --定义外键为Customers的cust_id字段
);

检查约束

CREATE TABLE OrderItems
(
    order_num     INTEGER     NOT NULL,
    order_item    INTEGER     NOT NULL,
    prod_id       CHAR(10)    NOT NULL,
    quantity      INTEGER     NOT NULL CHECK (quantity > 0), --约束其列值必须大于0
    item_price    MONEY       NOT NULL
);

ADD CONSTRAINT CHECK (gender LIKE '[MF]') --检查列中只包含M或F

索引

CREATE INDEX prod_name_ind --建立索引
ON PRODUCTS (prod_name); --建立索引的表下的列

触发器

CREATE TRIGGER customer_state --建立索引
ON Customers --表名Customers
FOR INSERT, UPDATE  --插入与修改操作
AS
UPDATE Customers
SET cust_state = Upper(cust_state) --cust_state列
WHERE Customers.cust_id = inserted.cust_id; --插入的数据表等于源数据的cust_id列

以下为示例用数据表
