- Define the Action**: Define the action to be taken when the condition is met. For example, you can create an action like “Filter out rows that don’t meet the condition”.
- Save and Test the Rule**: Save the rule and test it using sample data to ensure it’s working as expected.
Advanced Filtering Techniques
Now that you’ve learned the basics of filtering data using Evrete Rule Engine, let’s take it to the next level with some advanced techniques:
Using Logical Operators
Evrrete Rule Engine supports a range of logical operators that enable you to create complex conditions for filtering data. Here are some examples:
// Using AND operator
Condition: Age > 18 AND Country = 'USA'
// Using OR operator
Condition: Age > 18 OR Age < 30
// Using NOT operator
Condition: NOT (Country = 'USA')
Using Functions and Macros
Evrrete Rule Engine provides a range of built-in functions and macros that can be used to create more complex conditions for filtering data. Here are some examples:
// Using the LENGTH function
Condition: LENGTH(Name) > 5
// Using the CONTAINS macro
Condition: CONTAINS(Description, 'keyword')
// Using the DATE_PART function
Condition: DATE_PART(Birthdate, 'year') > 1990
Using External Data Sources
Evrrete Rule Engine allows you to use external data sources to filter your data. Here's an example:
// Using an external database
Condition: EXISTS (SELECT 1 FROM external_database WHERE CustomerID = CustomerID)
// Using a web service
Condition: WEB_SERVICE('https://example.com/api/customer eligibility', CustomerID) = 'true'
