(1)查询中含有计算列
SELECTc1,c2,c1*c2ASc3FROMtablename;(2)选出并列数据（不仅选出前10条，并列的c1数据也会显示）SELECTTOP10WITHTIES*FROMtablenameORDERBYc1;(3)选出不重复的数据
SELECTDISTINCTc1FROMtablename;(4)内联查询（将多个表联合查询的方式，显示符合条件的所有数据，左右叠加）SELECTc1,c2,c3FROMtablename1INNERJOIN

SELECTc1,c2,c3FROMtablename1RIGHTOUTERJOINtablename2ONtablename1.c4=tablename2.c5;(7)全联查（显示所有数据）
SELECTc1,c2,c3FROMtablename1FULLOUTERJOINtablename2ONtablename1.c4=tablename2.c5;(8)穿插联接（一表中的记录依次与二表中记录配对显示）SELECT*FROMtablename1CROSSJOINtablename2;(9)判断空值
SELECT*FROMtablenameWHEREc1ISNULL;(10)IN关键字（选出符合c1等于v1,v2,v3…的所有数据）SELECT*FROMtablenameWHEREc1IN(v1,v2,v3….);(11)模糊查询
SELECT*FROMtablenameWHEREc1like‘%v1%’;（%表示N个字符，_表示1个字符）
(12)EXISTS关键字
SELECT*FROMtablename1WHEREEXISTS(
SELECT*FROMtablename2WHEREc1=v1ANDtablename1.c2=tablename2.c3;);
(13)ALL,ANY和SOME关键字（与子查询连用，ANY和SOME相同都是指在进行比较运算符时只要子查询有一行能使结果为真则结果为真；而ALL表示子查询结果必须都为真，结果才为真）
SELECT*FROMtablename1WHEREtablename1.c1=ANY(
SELECTc1FROMtablename2WHEREc2=v2ORc3=v3;);
(14)WITHCUBE关键字（对GROUPBY的分组对象进行数量汇总统计）WITHROLLUP关键字（对查询结果中第一项进行进行数量汇总统计）SELECTc1,c2,c3FROMtablenameWHEREc4>v1GROUPBYc1,c2WITHCUBE(WITHROLLUP);
(15)HAVING关键字（与GROUPBY连用（不连用的话同WHERE,与WHERE的唯一区别是HAVING后可以使用汇总函数）.HAVING后写汇总函数）SELECTc1,count(c2)FROMtablenameGROUPBYc1HAVINGcount(c2)>v1;(16)COMPUTE关键字（对汇总函数进行归类,没有by的话进行整体汇总，有by的话进行分类汇总）
SELECTc1,c2,c3FROMtablenameWHEREc1=v1COMPUTESUM(c2)byc3(17)UNION关键字（合并多个查询结果，上下叠加）SELECTc1,c2,c3FROMtablename1UOION

3.6SQLAlias（别名）3.7SQLJOIN
用于根据两个或多个表中的列之间的关系，从这些表中查询数据。
语法
INNERJOIN：如果表中有至少一个匹配，则返回行
JOIN:如果表中有至少一个匹配，则返回行（与INNERJOIN相同）LEFTJOIN:即使右表中没有匹配，也从左表返回所有的行RIGHTJOIN:即使左表中没有匹配，也从右表返回所有的行FULLJOIN:只要其中一个表中存在匹配，就返回行
实例
"Persons"表：Id_P123"Orders"表：Id_O12345OrderNo7789544678224562456234764Id_P331165LastNameAdamsBushCarterFirstNameJohnGeorgeThomasAddressOxfordStreetFifthAvenueChanganStreetCityLondonNewYorkBeijing
（JOIN）实例
SELECTPersons.LastName,Persons.FirstName,Orders.OrderNo3.15SQLFOREIGNKEY约束
一个表中的FOREIGNKEY指向另一个表中的PRIMARYKEY。FOREIGNKEY约束用于预防破坏表之间连接的动作。
FOREIGNKEY约束也能防止非法数据插入外键列，因为它必须是它指向的那个表中的值之一。
语法
在"Orders"表创建时为"Id_P"列创建FOREIGNKEY：

Scalar函数的操作面向某个单一的值，并返回基于输入值的一个单一的值。MSAccess中的Scalar函数函数UCASE(c)LCASE(c)MID(c,start[,end])LEN(c)INSTR(c,char)LEFT(c,number_of_char)RIGHT(c,number_of_char)ROUND(c,decimals)MOD(x,y)NOW()FORMAT(c,format)DATEDIFF(d,date1,date2)描述将某个域转换为大写将某个域转换为小写从某个文本域提取字符返回某个文本域的长度返回在某个文本域中指定字符的数值位置返回某个被请求的文本域的左侧部分返回某个被请求的文本域的右侧部分对某个数值域进行指定小数位数的四舍五入返回除法操作的余数返回当前的系统日期改变某个域的显示方式用于执行日期计算CURDATE()CURTIME()DATE()返回当前的日期返回当前的时间提取日期或日期/时间表达式的日期部分返回日期/时间按的单独部分给日期添加指定的时间间隔从日期减去指定的时间间隔返回两个日期之间的天数用不同的格式显示日期/时间EXTRACT()DATE_ADD()DATE_SUB()DATEDIFF()DATE_FORMAT()SQLServerDate函数
下面的表格列出了SQLServer中最重要的内建日期函数：
函数GETDATE()描述返回当前日期和时间返回日期/时间的单独部分在日期中添加或减去指定的时间间隔返回两个日期之间的时间用不同的格式显示日期/时间DATEPART()DATEADD()DATEDIFF()CONVERT()SQLDate数据类型
MySQL使用下列数据类型在数据库中存储日期或日期/时间值：
DATE-格式YYYY-MM-DD
DATETIME-格式:YYYY-MM-DDHH:MM:SSTIMESTAMP-格式:YYYY-MM-DDHH:MM:SSYEAR-格式YYYY或YY
SQLServer使用下列数据类型在数据库中存储日期或日期/时间值：
DATE-格式YYYY-MM-DDDATETIME-格式:YYYY-MM-DDHH:MM:SSSMALLDATETIME-格式:YYYY-MM-DDHH:MM:SSTIMESTAMP-格式:唯一的数字
