Question

I have this query that is taking information from two different databases:

I’m using $query as the query string.

SELECT 
    blurbs.text,
    blurbs.timestamp,
    users.name,
    users.username,
    users.profilepic,
    users.id 
FROM 
    blurbs, users 
WHERE 
    (LOWER(blurbs.text) LIKE '%$query%' 
OR  LOWER(users.name) LIKE '%$query%') 
AND blurbs.is_private=0 
LIMIT 0,30

I am receiving duplicates of some of the entries in the blurbs database.

How can I fix this?

You have not joined both tables. You need to join it something like users.id = blurbs.userid:

So your query should be:

SELECT 
    blurbs.text,
    blurbs.timestamp,
    users.name,
    users.username,
    users.profilepic,
    users.id 
FROM 
    blurbs, users 
WHERE
    users.id = blurbs.userid
AND (LOWER(blurbs.text) LIKE '%$query%' 
     OR  LOWER(users.name) LIKE '%$query%') 
AND blurbs.is_private=0 
LIMIT 0,30

Or you can also use join statement like this:

SELECT 
    blurbs.text,
    blurbs.timestamp,
    users.name,
    users.username,
    users.profilepic,
    users.id 
FROM 
    blurbs JOIN users ON users.id = blurbs.userid
WHERE
     (LOWER(blurbs.text) LIKE '%$query%' 
     OR  LOWER(users.name) LIKE '%$query%') 
AND blurbs.is_private=0 
LIMIT 0,30
