Question

I inserted ‘vanity_name’ and ‘name’ into the first and second SELECT statements respectively.

I get a mismatched number of columns error, which I’m confused about because I added a column to both select statements to maintain a balance.

SQL Statement:

SELECT id, 
       vanity_name, 
       Date_format(DATE, '%M %e, %Y') AS DATE, 
       TYPE 
FROM   (SELECT resume_id AS id, 
               date_mod  AS DATE, 
               'resume'  AS TYPE 
        FROM   resumes 
        WHERE  user_id = '1' 
        UNION ALL 
        SELECT profile_id, 
               name, 
               date_mod AS DATE, 
               'profile' 
        FROM   profiles 
        WHERE  user_id = '1' 
        ORDER  BY DATE DESC 
        LIMIT 
        5) AS d1 
ORDER  BY DATE DESC 

Answer 1

Erm, you have four columns in your outer select, three in the inner select.

id, vanity_name, date, type

vs.

id, date, TYPE
