Validators not working when doing transition using drag and drop on board

[Adam Siemionczyk]

I created some validators for required fields. They are working fine when doing the transition using a drop down in the Edit Issue screen and when a filed value is missing, an error message is returned. However when doing the same transition from Board view by draging and droping the issue on next status in the workflow, all validators are ignored.

I don't have any transiton screen configured, because I don't need it.

I am using a business worklflow template.

Please help.

Furthermore the differences mentioned by Udo, I would add one more: 

SQL is standard while JQL is proprietary. It means that there are a lot of tools supporting SQL whereas JQL is restricted to JIRA. 

Fortunately, there is an add-on (SQL for JIRA) which brings all the power of JQL to SQL. Therefore users can take all the benefits of SQL and JQL working together.

JQL will give you always a list of issues - and only that. With SQL you can do more, aggregations, search for other things (Users, Projects, ...), etc.
