Hi. I have Matlab 2021b and Matlab 2024a installed and with Matlab 2021b I can easily connect to a database via an ODBC bridge just like in the documentation example :

conn=database('odbcdatasource','scott','tiger')

The same line of code doesnt work with Matlab 2024a. I get the error

Dot indexing into the result of a function call requires parentheses after the function name. The supported syntax is 'database().internal'.
Error in database (line 59)
connection = database.internal.utilities.hdatabase(varargin{:});

I dont get it. What am I doing wrong ?

Hello,

The issue may be occurring because the `pathdef.m` file was copied from MATLAB R2021b to R2024a without any changes. To resolve the issue make appropraite changes to the document.

Refer to the following links for more information:

Indeed, I changed the pathdef and now it works. Thank you for your answer. I still dont understand how the pathdef might cause the error above however
