Querying two tables help?
Hello, hope you are all well
I have a question. On my website I have a search facility, and when a user enters their search term it can either be interpreted as a category (held in my categories table) or a name of a title of a story (held in my stories table).
Now in the stories table each story belongs to a category from the categories table, which is storied as a foreign key in the stories table.
Now say the term entered is "racing" on my website for example, what I do is this currently is
(1) run a like query on the categories table to find all the catid's where term like '%racing%' to hold those id values in an array to use them in my later query like so
Select catid from categories where name like '%racing%'
Select * from stories where name like '%racing%' OR catid IN ('".implode("','",$array)."')
So currently I run two queries, which works OK, but I'd love to get it into one query. Is this possible?

See the manual for JOINs.

SELECT stories.give, stories.list, stories.of, stories.fields, categories.wanted FROM stories INNER JOIN categories ON stories.catid = categories.catid WHERE categories.name LIKE '%racing%' AND stories.name LIKE '%racint%'
SELECT stories.give, stories.list, stories.of, stories.fields, categories.wanted FROM stories, categories WHERE stories.catid = categories.catid AND categories.name LIKE '%racing%' AND stories.name LIKE '%racint%'
SELECT S.give, S.list, S.of, S.fields, C.wanted FROM stories AS S, categories AS C WHERE S.catid = C.catid AND C.name LIKE '%racing%' AND S.name LIKE '%racint%'Be yourself. No one else is as qualified.
