I am a first time user of Matlab.

I need to connect to a custom database (I have the jdbc driver) to import some data for analysis.

Our IT says the Database Toolkit is installed with the product. But when I try to create a connection (following the docs) I get the following error:

>> conn = database('TeiidOW', 'user', 'user', 'teiid-8.4.0.Final-jdbc','jdbc:teiid:OpenWorks@mm://localhost:31000;version=1'); 
Undefined function 'database' for input arguments of type 'char'.

BTW, I added the jdbc driver to classpath.txt and restarted MatLab.

Any pointers are much appreciated.

Thanks in advance Srini

Use the

ver

command to list all installed toolboxes. Additionally, you can list all licensed toolboxes with

license('inuse')

It is actually both - you need to check with VER if it is installed and LICENSE to see if it is licensed. There are good reasons why in your environment only one is true.

Note that the 'inuse' option would only return what you successfully haved used. In your case it is better to run

license('test','Database_Toolbox')

which should return 1.
