How to query SQL by the same number of records issue from JQL

[Le Anh Son (K14 HL)]

I want to using query statement from SQL to getting all of record about issue in database with condition that the number of result must be the same with JQL. Anyone can help me?

Requirement: Getting all of issue that belong to one project and sprint

Seriously, don't bother.  The Jira database is not remotely designed for any form of reporting, it is a data store.

You are wasting your time trying to use SQL to report on your Jira data.  The best case is that you'll get an inaccurate report.  The worst case is that you'll take your server down with a hideously non-performant slab of complex SQL.

It's not that difficult and would take 3 tables and 2 where conditions, question is, why do you think you want to get this from the database, when you can already get it from Jira? Not to be the annoying guy, but from what I came across almost every time there is no need to stick fingers in DB, it's not the meant way to do reports or data collection, and if you're not already familiar with the structure, it will be rather tedious for you to expand on it any further.
