Mysql query search a string in all columns of a table

Question

I wonder how I can mount a SQL as portable as possible to query for all columns of a table for a specific phrase, like:

Table

ID | Name          


        

Answer 1

It's doable, although I strongly suggest you look into full-text search for efficiency;

To avoid looking for all patterns in all fields one by one, you can just concat and search in that;

SELECT *
FROM (SELECT id,CONCAT(name,'|',text,'|',date,'|',author,'|',status) txt
      FROM Table1) a
WHERE txt LIKE '%augusto%'
  AND txt LIKE '%2010%'
  AND txt LIKE '%text%';

Note that no indexing will help you here, since you're searching in a calculated column. On the other hand, since you're searching with a leading wildcard %searchterm, you won't get much help from indexes even if searching field by field :)
