Trouble writing a query
Hi,
I'm using MySQL 5.0. I have three tables ...
MODULES (lists available content for the page, e.g. Gmail, ESPN, CNN)
----------------
ID
NAME
TABS (lists names of groups of modules)
---------
ID
NAME
TAB_MODULES (lists modules that go in each group)
-----------------------
ID
MODULE_ID (foreign key to MODULES.ID column)
TAB_ID (foreign key to TABS.ID column)
I want to write a query that tells me whether a module is displayed on
a tab, given a tab's ID. The result set should always contain the
same number of rows as SELECT COUNT(*) FROM MODULES. I would like it
to contain
MODULE_NAME (name of module)
SELECTED (either 1 or 0)
How do I do this?
Thanks, - Dave
