Can you mention what you are trying to do?
Probably your “run query” procedure is having problem

im sorry sir, im newbie. sorry for bad english.
im practice with this app
when i open this screen i want to make a list

then i get data from web my sql database…
can you help me fix this sir?

Received a 200 code, that is not a mistake, it means that the data was obtained successfully

There is an error in your blocks

For a simpler solution I recommend using the MySQL Database extension from DeepHost, it also has an example AIA for use with ColinTree ListView

The Deephost extension did not work well in SQL queries.


Work well for me

Funciona bien para mí

All right, I’ve got the wrong version

as I can see, you are following the MySQL tutorial from here App Inventor Tutorials and Examples: MySQL | Pura Vida Apps

as it already has been said, this is not an error, just remove the Notifier and try again

@alexitoo_uy which extension are you talking about? any link? as far as I know, a MySQL extension is not possible, because MySQL runs on a web server…




This extension

Is based on your MySQL script from what I saw

@alexitoo_uy thank you for letting me know…
it seems to be, I have to add a few more extensions from @Deep_Host into the extensions directory:wink:

@Deep_Host congratulations! this looks like a great extension, which is based on my script from here App Inventor Tutorials and Examples: MySQL | Pura Vida Apps

Also you might want to follow the naming conventions… which are UpperCamelCase for property, method and event names (i.e. the first letter should be a capital letter) and lowerCamelCase for parameter names, i.e. no underscores



Keep up the good work!


Take it just as a suggestion…
As I can see you are using AIA of jobworld app made by Sanjay Dey I would like to tell you that there are a lot of bugs in that AIA.
Just a suggestion…:sunglasses:

Ok, let me help you. Read this: How to ask a question?


I have problems running a simple query:
I put into a Run Query instruction block but it doesn’t return any result.

Where ‘QR20194’ is defined by a TEXT Box

I had the same problem a long time ago. I used the Deephost extension, all its blocks work except the block to make an SQL query, I’ve written to him (Deephost), commented your videos, followed your tutorials that just don’t have the example of SQL queries. I received no response and now I’m using the Taifun tutorial which is great for making SQL queries.
