OQL DATA QUERYING
Are your replacing your legacy SQL database with custom logic built in the queries or do you want to go beyond Xpath for some advanced reporting or speed? In that case, the OQL workshop is for you!
Do you sometimes have the feeling that your application can perform better in retrieving data? Then it is time to get more knowledge of OQL. Mendix Object Query Language is like SQL and you can build your own database queries to retrieve the data, these can be simple but also very complex. We will learn you how to use OQL and you will get a lot of time to practice during this hands-on training.
The Mendix Object Query Language (OQL) is a relational query language just like SQL. The major advantage of OQL is that it uses entity and association names instead of actual database table names.
In addition, OQL can use predefined relations (associations) to easily join objects without having to calculate which columns should be coupled.
