How to suppress "Warning: ATTR will be removed in a future release" when update( ) MySQL?

7 views (last 30 days)
Everytime I use the update( ) function to update a row in a MySQL table, the warning message is displayed
Warning: ATTR will be removed in a future release
My program was updating thousands of rows in a MySQL table, and the warning is displayed thousands of times. As a result, I couldn't see other warning messages or my own prompt message.
What should I do to suppress that warning specifically? Or should I replace update( ) with another function?

to suppress a specific warning you need to find it's identifier using:
w=warning('query','last'); %store last warning as a 2 field struct (identifier,status)
wid=w.identifier; %store identifier
and then turn it off with:
warning('off',wid); %set warning to off
in a similar fashion you can turn it on again if needed.
For the warning itself i wouldn't worry too much, still you could try to run an update query from matlab instead of using the update function.:
SQLdbconn=database('SQLDatabaseName','username','password'); %make connection to database
query= ['UPDATE table_name SET column1=value WHERE condition']; %create query as string
data=fetch(SQLdbconn,query) %execute update query and fetch results

I actually was wanting to do the 'accept', but I couldn't find the button to click.
Could you repost your answer as 'Answer this question?' Thanks.
