Mysql: Order by like?

Question

assume that we are performing search using keywords: keyword1, keyword2, keyword3

there are records in database with column \"name\":

1: John Doe
2: Samue         


        

Answer 1

 SELECT * 
 from
 (
  SELECT u.*, 1 OrderNum 
  FROM users 
  WHERE (name LIKE "%John%")
  UNION 
  SELECT u.*, 2 OrderNum 
  FROM users 
  WHERE (name LIKE "%Doe%")
  )
  Order by OrderNum

Answer 2

My example will Order all of the John's Alphabetically followed by the Doe's.

ORDER BY CASE
    WHEN name LIKE "John%Doe" THEN CONCAT('a',name)
    WHEN name LIKE "John%"    THEN CONCAT('b',name)
    WHEN name LIKE "%Doe"     THEN CONCAT('c',name)
    ELSE name  
END  

Answer 3

To build on RedFilter's answer, you could make the rows that have both keywords to be at the top:

order by case 
when (name LIKE "%John%" and name LIKE "%Doe%") then 1 
when name LIKE "%John%" then 2
when name LIKE "%Doe%"  then 3
end

Answer 4

order by case 
    when name LIKE "%John%" then 1 
    when name LIKE "%Doe%"  then 2 
    else 3 
end

Answer 5

Read up on Boolean Fulltext Searches, with which you can do ordering.
