EXCEL 鏈接字符串 MYSQL

要把EXCEL 中的內容 轉換成MYSQL 語句 導入到數據庫中，因而找來找去 找到了 CONCATENATE函數

主要的就是:

1.將你想要另外添加的字符用雙引號引發來 不一樣的列之間用逗號分隔。

如下目的就是將 A1  轉換成 '週三'

A2轉換成501660

A3轉換成'DX02'

("insert into usercode values("  其實轉換成了 insert into usercode values(

而那些 引號  逗號 所有都須要用""   分開來。

1）每一項須要用逗號分開，包括"A1" 須要折分爲 ",a1,"

,"'",A1,"'"  第一個逗號爲將前一項分開的符號，而"'"爲添加單引號

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

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

一個字符串類型需轉換爲：注：分隔項不須要添加引號。

,",","'",Ax，"'",

第一個逗號爲，分隔每個項，第二個加雙引號的逗號爲須要轉換出來的逗號，

第三個逗號依舊爲分隔項逗號，第四個加雙引號號的逗號爲須要轉換出來的逗號，

第五，第六都爲分隔逗號，第七個加雙引號的逗號爲轉換出來的逗號，最後爲分隔項

   

若是須要轉交數字類型只須要在先後加2逗號就能夠  以下：501660

,",",b1,",",

=CONCATENATE("insert into usercode values(","'",A2,"'",",","'",D2,"'",")",";")       結果：insert into usercode values('1','4');

insert into usercode values('週三',501660,'DX02','DX0202');

A        B       C          D

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

=CONCATENATE("delete from donson_usercode where user_code=",A1,";")   注: A1爲主鍵
