Hello All,

I have an issue with setting case sensitive of alphanumeric sequence from database. I would appreciate your kind help as i have included the script, so as to show if its my misstake or just not possible with alphanumeric sequence.

Hej, mcvroh,

sorry, don't understand this:

I have an issue with setting case sensitive of alphanumeric sequence from database.

?

Hi Klause,

An example... on database (xaYj1E2)
when i type (xayj1e2) am expecting it to answer wrong code. but it just accepts it

mcbroh

Hm, still not sure I quite understand, but I guess this is more a SQL than a Livecode problem.

Sorry, I do not know how to solve this problem.

Thanks Klaus,

would keep cracking my head out

Hi,

regarding the script in the OP - assuming that only the "end getPoint" is lacking:

The script starts with an already open DB (gConnectionID).
Then you grab a Code from a field & put it into tCodes. Be it "123" for now.
Then you fill the variables tTableCodes & tTableName - where tTableName istn't used anymore later ...
And construct an SQL-String: "SELECT Points from codes WHERE Codes= '123'"

Remark: Seems you have a table that contains a field with the same name? This is crying for problems, IMHO. A way to escape it is to construct something like this:
"SELECT codes.Points from codes WHERE codes.Codes= '123';"
And it never hurts to close with a semicolon, too ;-)

Now we should receive (in tData) the Points-value of the row where codes is 123. If Points is zero, it's a used code.
Then:
... if item 1 of tData is field id 1098 then
Item 1 of tData is the points (you only asked for them!)! And you compare it to the Code?

Remark 2: OK, maybe you didn't post all of the code, maybe this is beyond my scope - as I see it, only if Points = 123 in the row where Codes = 123 it will execute at all...

Regarding "caseSensitive":

Dictionary: "Specifies whether comparisons treat uppercase and lowercase letters as different."
This is for LiveCode only, as I understand it!
There's only one comparison in the code, and this tests tData, the Points (a number?).

Regarding the database name in the second post:

Try this in the message box (multi-lines): Returns false, as it should. (LC-C 6.7.1)

Further:

When you call a database or a table by name, it's dependent on what system it runs:
- Win is case-insensitive
- Linux is case-sensitive
- Mac is whatever
(- and I may be wrong, but at least this way it always worked for me ...)

When you call a field by name (in SQL), even in MySQL on Linux it isn't case-sensitive. Was there, tried it, reporting here.

Hope I was able to add to the general confusion ;-)

Have a good time!

hello Axwald,

thanks for your input.
i figured it out now. i can not check case sensitiv directly from within the Database. i have to put the info first into a variable on app and then case sensitive can work.

Thanks
