忽略空格的查询 [英] Query that ignore the spaces

问题描述

运行查询以便字段中的空格是
被忽略的最佳方法是什么？例如，以下查询：

  SELECT * FROM mytable WHERE username =JohnBobJones
 SELECT * FROM mytable WHERE username =John Bob Jones
  

会找到以下条目：

  John Bob Jones 
 JohnBob Jones 
 JohnBobJones 
  

我使用php或python，但我认为这没关系。

解决方案

p> SELECT * FROM mytable
WHERE REPLACE（username，''，''）= REPLACE（John Bob Jones，''，''）


What's the best way to run a query so that spaces in the fields are ignored? For example, the following queries:

SELECT * FROM mytable WHERE username = "JohnBobJones"    
SELECT * FROM mytable WHERE username = "John Bob Jones"

would find the following entries:

John Bob Jones
JohnBob Jones
JohnBobJones

I am using php or python but I think this doesn't matter.

解决方案

SELECT * FROM mytable 
    WHERE REPLACE(username, ' ', '') = REPLACE("John Bob Jones", ' ', '')
