Usage of the language to access data from a Domino database

  • Fulltext Indexing of a Domino database is not necessary for better performance !
  • No sort functions available with DQL – therefore you have to use other tools ( Node.JS for example )
  • Design Catalog GQFdsgn.cat has to exist on the Domino Server which is currently not automatically created !!!
  • Currently there’s no security available in DQL – this is a feature for the future and is coming with IAM

Here’s an example how to use DQL:

So DQL is a great feature when you have to access Domino databases for displaying a small result set in any frontend via Node.JS. Get additional information about this new feature in the “Getting started-lab” using the following link: http://ibm.biz/dql-lab
