sqlfind is not a sole function but a method for database. Below is a part of database.m.

%   database methods:
%   -----------------
%       sqlwrite           - Insert MATLAB data into database table.
%       sqlread            - Import data into MATLAB from database table.
%       sqlfind            - Find information about all table types in
%                            database.

You can run the command below to open an example. Please check if sqlfind works in the example with the context of using "database".
