Question

I want to write a query to search in multiple tables (news, articles, projects, files)

While searching I found this

SELECT title, post FROM news WHERE MATCH (title,post) AGAINST ('press');

I tested it and it’s working, but i failed to extend this to multiple tables.

How to write one query that return me search results for multiple tables ?

Answer 1

One method is to use a union:

SELECT title, post FROM news WHERE MATCH (title,post) AGAINST ('press')
UNION
SELECT title, post FROM articles WHERE MATCH (title,post) AGAINST ('press')
UNION
SELECT title, post FROM projects WHERE MATCH (title,post) AGAINST ('press')
UNION
SELECT title, post FROM files WHERE MATCH (title,post) AGAINST ('press')

This now essentially becomes one pseudo table with all of the records merging into one dataset.
