Converting data from MySQL database to usable values

Solved!
Go to solution

1) Why is it a 2x2 array ?

- A table is a collection of related data held in a structured format within a database. It consists of columns, and rows.


2) How do i take a selected value for example. i only want to the value 3333 to be taken out from database. 

- You can use Index Array and give proper row and column index to get the element in array.


3) How do i add the 3rd (3333) number and 4th (4444) number from database after getting the value out from array?

 


-After indexing elements you can use Add Function


4) I am a beginner in labview and all other programming. Is there any way to learn ?

Hi Udka,

 

I want the data to up date every 1 min interval is there any better way going about this beside adding a while loop to it ? If I were to use while loop, the program will have to open and close the database every loop while i think it is not very practical. But i can't think of another way to do it.

You can create a VI With different cases as OPEN, READ,CLOSE of database, Keep the Reference in the shitregister, call the OPEN and CLOSE cases before and after Loop, call READ case Inside Loop.
