Database

I was wondering how you would go about creating a search database.

First, off how could you make a table look for a key that matches an io.read input from the user?

Secondly, how could you add a new key/value created in an array based on user input?

Bascially how can you create new tables or keys/ values in a table and how can you then search for them? Will it work with nested tables?



–Thanks in advance for any help! I really appreaciate anything you can suggest!

To use a variable as a key & search, you can do this:

local var = read()
if tbl[ var ] == "something" then
 --#do stuff
elseif not tbl[ var ] then
  tbl[ var ] = read()
end

Just for clarification, if var = read() in line 1 then why is it declared again in line 5? Couldnt you just delcare a new table equal to the local var?

What I was doing there, is if the users input exists within the table then do this, else ask for another input and set the first input within the table equal to the second input.

eg:
if tbl is

{ King = "Hello" }

then doing this:

Yami

would prompt again, at which point I could type in

Goodbye

And the table would then look like:

{King = "Hello", Yami = "Goodbye" }
