Hello, Since you have only carthesian joins we can transform them into joins and index them in order to have them work as fast as you want. We can also work with views regarding this in order to have them read from your application faster and smoother. Thank you.

I can help you with the queries you need! I work with different kind of joins in access and Oracle databases everyday.

Hi i've around 5 years experience working with database and worked on many complex problems that needed joining multiple tables and performing aggregation, filtering, sorting etc. I've hand on experience of working on call center data for different KPIs i.e. Customers, Sales, Calls, Agents, products, partners etc so you can imagine how complex the structure and hence query sometimes can be. And i've done all of them. LibreOffice will be something new, but i will love to work on it and am pretty sure to deliver the desired work in time. thanks

Hi I have extensive experience of SQL writing complex queries, and where needed stored procedures. Not being aware of precisely what you require, the best solution may be one or the other (query or stored procedure) or a mixture of both. Since you are using LibreOffice base, I would like to know if you are using the default HSQLDB or another DB such as SQLite. Much of my day job requires me writing a lot of complex SQL and to speed up old SQL queries, so I think I will be able to give you the benefit of my experience. And once done I should be able to explain the reasoning behind the solutions if that is what you want. Looking forward to hearing from you. Chana T
