I'm writing a query where I'm looking to pull related fields from a database with a limit of 10 rows.

The query is easy to write, however I was wondering if there is a way to write the query so it searches for related items开发者_运维问答 and pulls those first and if those are < 10 it will just pull random fields for the remaining ones.

Here is the query I use to pull the related rows

SELECT * FROM table WHERE term LIKE '%term1%' or term LIKE '%term2%' LIMIT 0,10


Your just need to order the table by the terms that you are looking for first, one way of doing this is as follows:

SELECT * FROM table 

ORDER BY (
  (
    CASE WHEN term LIKE '%term1%'
    THEN 1
    ELSE 0
    END
  ) + (
    CASE WHEN term LIKE '%term2%'
    THEN 1
    ELSE 0
    END
  )
) DESC
LIMIT 0,10
0
