EXCEL 连接字符串 MYSQL

要把EXCEL 中的内容 转换成MYSQL 语句 导入到数据库中，于是找来找去 找到了 CONCATENATE函数

主要的就是:

1.将你想要另外添加的字符用双引号引起来 不同的列之间用逗号分隔。

以下目的就是将 A1  转换成 '周三'

A2转换成501660

A3转换成'DX02'

("insert into usercode values("  其实转换成了 insert into usercode values(

而那些 引号  逗号 全部都需要用""   分开来。

1）每一项需要用逗号分开，包括"A1" 需要折分为 ",a1,"

,"'",A1,"'"  第一个逗号为将前一项分开的符号，而"'"为添加单引号

=CONCATENATE("insert into usercode values(","'",A1,"'",",",B1,",","'",C1,"'",",","'",D1,"'",")",";")

=CONCATENATE("insert into usercode values(","'",A1,"'",",",B1,",","'",C1,"'",",",D1,",","'",E1,"'",",","'",F1,"'",",","'",G1,"'",")",";")

一个字符串类型需转换为：注：分隔项不需要添加引号。

,",","'",Ax，"'",

第一个逗号为，分隔每一个项，第二个加双引号的逗号为需要转换出来的逗号，

第三个逗号依旧为分隔项逗号，第四个加双引号号的逗号为需要转换出来的逗号，

第五，第六都为分隔逗号，第七个加双引号的逗号为转换出来的逗号，最后为分隔项

   

如果需要转交数字类型只需要在前后加2逗号就可以  如下：501660

,",",b1,",",

insert into usercode values('周三',501660,'DX02','DX0202');

A        B       C          D

艾娜	501633	DX02	DX0202	insert into usercode  values('艾娜',501633,'DX02','DX0202');
东坡	501634	DX02	DX020801	insert into usercode values('东坡',501634,'DX02','DX020801');

=CONCATENATE("delete from donson_usercode where user_code=",A1,";")   注: A1为主键
