字符串索引的MySQL

Question

我需要一些幫助，在mysql.I串索引功能需要從開始圖形返回下列字符串的一部分字符串的結尾：

Michael Jackson Jannet -> SubString 1: Michael /SubString 2: Jackson Jannet 
Lincoln Obama Kennedy Washington -> SubString 1: Lincoln/SubString 2: Obama Kennedy Washington 

Answer 1

是否InStr函數（）功能適合您的需求？ 搜索字符串中的第一個空格，現在就知道該位置。然後用左（）和MID（）繩剪斷兩子：

pos = InStr("Michael Jackson Janet"," ") 
substring1 = Left("Michael Jackson Janet", pos - 1) 
substring2 = Mid("Michael Jackson Janet", pos) 

如果你堅持使用子串（）函數，你可以這樣說：

pos = InStr("Michael Jackson Janet"," ") 
substring1 = SubString("Michael Jackson Janet", 1, pos - 1) 
substring2 = SubString("Michael Jackson Janet", pos + 1) 

這是否幫你？

Answer 2

 
select substring('Michael Jackson Jannet',1,(locate (' ','Michael Jackson Jannet'))) as firstNBame, 
     substring('Michael Jackson Jannet',(locate (' ','Michael Jackson Jannet'))) as secondName;
