Hi, I have a MySQL table with a column that contains some of a web site
directory's category names in the format:
Sports:Football:Players
I am trying to build a query that that locates all records that match the
above category name OR if none exist its parent "Sports:Football" OR if none
exist its parent "Sports". The top level category, in this case "Sports",
will always have at least one matching record.
I know I can do this with multiple queries by checking the previous query's
result, but I am trying to build a query that does it all in one lookup to
avoid lots of lookups in deep categories. Something along the logical lines
of ...
SELECT * FROM table WHERE category = 'Sports:Football:Players' OR IF NONE
category = 'Sports:Football' OR IF NONE category = 'Sports'
... of course the above query does not work but if anyone knows of how to
accomplish something similar in one query I would much appreciate it.
Thanks!
