Undefined multiple IDs. Taking a decission

Hi all!

I'm beginner in MySQL. Actually, I've developed a couple of very
simple Php-WEB-Mysql interfaces but the one I'm working on now is a
bit more difficult.

Take a building company (BUILDINGCO) that has different PROJECTS in
different places where each project includes PRODUCTS as flat
apartments, shops, parking spots, etc.

I was planning to create a table called BUILDINGCO which lists all the
different PROJECTS they have. Every row would have an INT which will
be the primary key of the projects stored in a table called PROJECTS.
Is that correct?

Then, in the PROJECT table I was planing to store primary IDs of the
products of a table called PRODUCTS (like pointers in C).
The question is: In this PROJECTS table there will be many different
types of products they sell (parking spots, apartments, etc.) This
could be 3 products or 20. Who knows. How do I create this? Do I need
to create multiple columns and only use the ones I need? This doesn't
seem too elegant.
I've got C/C++ backgounds and sometimes get confussed. I'd like an
array which could be resized.

Any ideas?

Thanks!

I was recently reading an article about sequence points that used the canonical i = i++; as an illustration of modifying a variable multiple times between sequence points. Curiously the article did not indicate the type of i. Is it fair to say that if i was an instance of a class type that overloaded

Can you do a search for more that one string in another string? Something like: someString.IndexOf("something1","something2","something3",0) or would you have to do something like: if ((someString.IndexOf("something1",0) >= 0) || ((someString.IndexOf("something2",0) >= 0) ||

You can test for an undefined value in two ways: function blah(x) { if (x == undefined) { x = 'default value'; } } That could also have been written: function blah(x)

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
