Hello, in this video, I will talk about bind variables and overriding methods. What is bind variable Ben variable is used to accept a value. At runtime. If you want to filter some query, you need to send this parameter at runtime like for example, you need to send the user a login user ID. So depending on the user who will log into the system, you need to take this user ID and send it to the query to filter some data or as a user will enter a date from to end you need to filter the data. So binding variable will use it to accept any parameter at runtime to filter the data.

So bind variable will be defined in two places. So one will be in the view object query itself. So in the view object query, you can define some binding variable All in the view criteria view criteria as well can define very bind variable and you can send the barometer to their view criteria to filter the mean view object data. How you can sit this bind variable there are multiple ways you can do it. You can use groovy expression in the view object level and I will show you how you can do this all from back pain in the back being self you can get the view criteria or you can get the view object and you can set the bind variable or using overriding methods. What is overriding methods I will cover some of the overriding methods in the model layer in the view object or the entity object or application module.

You can override some predefined methods and I will show you how you can define something exam which I usually use. In this example, I will show you how you can override methods to set a bind variable and set view object. overriding method can be done in application module class embed or entity object embed or view on bill, or viewed or embedded in Java clause in the module layer, you can override some of these methods. This is generally what is bind variables and override methods. So when it comes to video, let's go to the developer and start to make some examples for it is bind variables and overriding methods. So see you when you consider it.
