newbie: "complex" query Hi all,
I've a problem writing a VB 2005 application that interacts with a mysql
database that stores the correspondence with our customers.
I hope you can understand me since I'm italian.
I've got two tables:
the first one is called CORRESPONDENCE and is similar to this:
id subject cathegory
--------------------------------
1 bla bla bla 1
2 bla123 1
3 bla1 bla2 bla3 2
4 123blabla 1
.... ... ...
the second one is called CATHEGORIES:
id description
--------------------
1 italy customers
2 france customers
3 uk customers
.... ...
So as you can se the "cathegory" column of the first tables simply
indicates the cathegory which a letter belongs to (italian customers,
french customers and so on)
Now I want to build a query that simply list all the stored letters,
showing the description of their cathegory, not only its id.
the outpuk should look like this:
1 bla bla bla italy customers
2 bla123 italy customers
3 bla1 bla2 bla3 france customers
4 123blabla italy customers
....
This work should be done with a single query, without using subroutines
or subqueries. I would use something like:
"SELECT id, subject, cathegory FROM correspondence ORDER BY id
AND id, description FORM cathegories WHERE
cathegories.id=correspondence.cathegory"
But of course I dont't know the correct syntax, supposing of course this
could be possibile! :-)
thanks in advance
