mysql——表的導出——用select……into outfile導出 xls文件和文本文件

可以使用select……into  outfile導出txt、excel等格式的文件

 

語法格式： select  [ 列名 ]  from  table  [ where  語句 ]  into  outfile  ‘目標文件’  [  option ];

 

語句可以分為兩個部分，前面是一個普通的select查詢語句，通過這個語句查詢處所需要的數據；

                                       后部分是導出數據導到哪里，以及導出數據的格式；

------------------------------------------------------------------------------------------------------------------------------------

‘目標文件’：指將查出的記錄導出到哪個文件；

 

option：有常用的5個選項，分別如下：

 

fields  terminated  by  '字符串'：設置字符串為字段的分隔符，默認值是‘ \t ’；

 

fields  enclosed  by  '字符'：設置字符來括上字段的值。默認情況下不使用任何符號；

 

fields  optionally  enclosed  by  '字符'：設置字符來括上char，varchar，text等字符型字段，默認情況下不使用任何符號；

 

fields  escaped  by '字符'：設置轉義字符，默認值為“\”；

 

lines  starting  by  '字符串'：設置每行開頭的字符，默認情況下無任何字符；

 

lines  terminated  by  '字符串'：設置每行的結束符，默認值是‘\n’;

select sx,mz,bz from cr01 into OUTFILE 'C:/Users/del/Desktop/a.txt'
fields terminated by '、'optionally enclosed by '\"' lines starting by '\>' terminated by '\r\n';
    字段的分隔符              字符上加括號                   開頭                    結尾換行



PS：Windows下：  \r\n   是換行

   

 

 

------------------------------------------------------------------------------------------------------------------------------

前期數據准備：

create table cr01 ( sx int(50),
                    mz varchar(50),
                    bz varchar(50)
                   );


insert into cr01 ( sx,mz,bz ) values (1,'sww','sww01');

insert into cr01 values (2,'aww','aww02');

insert into cr01 values (3,'qww','qww03'),
                        (4,'eww','eww04'),
                        (5,'rww','rww05');

insert into cr01 ( sx,mz,bz ) values (6,'yww','yww06'),
                                     (7,'uww','uww07');

select * from cr01;

 

 

 

 

 

 

 

 

單表導出為xls文件，導出到桌面：

     select sx,mz,bz from cr01 into OUTFILE 'C:/Users/del/Desktop/a.xls'

示例：select * from cr01 where sx in (1,3,5,7) into OUTFILE 'C:/Users/del/Desktop/a.xls'

create table employee ( num int(50),

                        name varchar(50),
                        age int(50),

                          d_name varchar(50),
                          functione varchar(50),
                          address varchar(50)
                        );

insert into department values(1001,'keyanbu','yanfachanpin','3lou5hao');
insert into department values(1002,'shengchanbu','shengchanchanp','5louyiceng');
insert into department values(1003,'xiaoshoubu','cehuaxiaoshou','1louxiaoshoudating');



select * from employee;

select * from department;

多表導出為xls文件：（左連接）

select num,name,employee.d_id,age,sex,d_name,functione from employee left join department on employee.d_id = department.d_id
into OUTFILE 'C:/Users/del/Desktop/a.xls';

 

 

 

 

 

 

 

 

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

右連接：

select num,name,employee.d_id,age,sex,d_name,functione from employee right join department on employee.d_id = department.d_id;

select num,name,employee.d_id,age,sex,d_name,functione from employee right join department on employee.d_id = department.d_id
into OUTFILE 'C:/Users/del/Desktop/a.xls';

 

 

 

 

 

 

 

 

 

 

 

 

 

========================================================================

導出文本文件：

select sx,mz,bz from cr01 into OUTFILE 'C:/Users/del/Desktop/a.txt'
fields terminated by '\、' optionally enclosed by '\“' lines starting by '\>' terminated by '\r\n';

 

 

>1、“sww“、“sww01“
>2、“aww“、“aww02“
>3、“qww“、“qww03“
>4、“eww“、“eww04“
>5、“rww“、“rww05“
>6、“yww“、“yww06“
>7、“uww“、“uww07“

 

 

 

 

 

 

 

=========================================================================================

修改參數：

select sx,mz,bz from cr01 into OUTFILE 'C:/Users/del/Desktop/a.txt'
fields terminated by '\t'optionally enclosed by ' ' lines starting by ' ' terminated by '\r\n';

 1     sww      sww01
