It looks like the Visual Query Builder was removed in MATLAB R2017a. You can use the Database Explorer app instead. Also, some of these functions including the Database Explorer app are a part of the Database Toolbox. You can check that you have a license for the Database Toolbox by typing
ver
in the MATLAB Command Window and it should be listed. You can get this toolbox through the Add-Ons Explorer.
