Retrieve LV stored 2D-Array via MySQL C-API

 Hello everybody!

 

I am not quite sure, if this is the right place for my question, but I'll just give it try.

 

I have a LabVIEW Vi which performs Data Acquistion-Tasks. The Data is stored in a MySQL-Database using the Labview Database Connectivity Toolset. One part of the stored data is a 2D-Double-Array. For storage in MySQL It is automatically converted to Binary Data and the stored in a MySQL Blob-Field.

 

Unfortunately, the software to process the data is written in C++. It was fairly easy to establish the communication between my c++ application and MySQL via the MySQL C-API. But now i'm struggling to retrieve the Binary-Data from the Database and reconvert it into a C++ Double Array, as am not very experienced with C++.

 

Has anyone done something similar before?

Hello
 
I am happy to hear that your LabVIEW application and data storage with the LabVIEW Database Connectivity Toolkit works.
 
Unfortunately is this the wrong platform to ask about C++. There are many other open platforms discussing C questions. I’d propose you to ask your question there.

Best Regards
