Use Cases
Dynamic Apex is a powerful feature of the Salesforce platform that allows developers to write Apex code that can be executed at runtime. This means that the code can adapt to the current context and data, making it more flexible and efficient. In this blog post, we will take a closer look at Dynamic Apex and explore how it can be used to improve your Salesforce development.
Benefits
One of the main benefits of Dynamic Apex is that it allows developers to write code that can be executed at runtime. This means that the code can adapt to the current context and data, making it more flexible and efficient. For example, you can use Dynamic Apex to dynamically query the database based on user input, or to dynamically generate a list of fields to display on a page.
Another benefit of Dynamic Apex is that it can be used to write code that is more reusable. For example, you can write a single piece of code that can be used in multiple contexts, such as querying different objects or displaying different fields. This can save time and effort for developers and make it easier to maintain the code.
To get the best out of Dynamic Apex, it is important to understand the different types of Dynamic Apex and when to use them. There are two types of Dynamic Apex: Dynamic SOQL and Dynamic SOSL. Dynamic SOQL allows you to write dynamic queries that can be executed at runtime, while Dynamic SOSL allows you to write dynamic search queries.
Sample code
Here’s an example of how to use Dynamic Apex to query the database at runtime.
// Example of dynamic SOQL
String objectName = 'Account';
String fieldList = 'Name, Industry';
String whereClause = 'Industry = \'Technology\'';
List<sObject> results = Database.query('SELECT ' + fieldList + ' FROM ' + objectName + ' WHERE ' + whereClause);In this example, the object name, field list, and where clause are all passed in as variables. This allows the code to be reused for different objects and queries.
In a nutshell
In conclusion, Dynamic Apex is a powerful feature of the Salesforce platform that allows developers to write code that can be executed at runtime. It can be used to improve the flexibility and efficiency of your code, as well as making it more reusable. By understanding the different types of Dynamic Apex and when to use them, you can make the best of this powerful tool.
