Question

I am trying to use the following query with my table:

SELECT ARTICLE_NO, USERNAME, ACCESSSTARTS, ARTICLE_NAME, date_format(str_to_date(ACCESSSTARTS, '%d.%m.%Y %k:%i:%s'), '%d %m %Y' ) AS shortDate FROM AUCTIONS WHERE upper(ARTICLE_NAME) LIKE '%hardy%' and subcat = 'null' ORDER BY str_to_date(ACCESSSTARTS, '%d.%m.%Y %k:%i:%s'), article_no limit 0, 10

This should return over 100 records. subcat is null by default. Have I marked null incorrectly, or is there a different way to return records where a column is null?

Answer 1

The query should look like this:

SELECT ARTICLE_NO, USERNAME, ACCESSSTARTS, ARTICLE_NAME, date_format(str_to_date(ACCESSSTARTS, '%d.%m.%Y %k:%i:%s'), '%d %m %Y' ) AS shortDate 
FROM AUCTIONS
WHERE upper(ARTICLE_NAME) LIKE '%hardy%' and subcat IS NULL
ORDER BY str_to_date(ACCESSSTARTS, '%d.%m.%Y %k:%i:%s'), article_no limit 0, 10

Notice the subcat IS NULL in the WHERE clause.
