In Salesforce, relationships between objects are very important because they help us connect data across different objects, such as Account, Contact, Opportunity, and more.
Normally, we use relationships like lookup or master-detail where one field connects to only one object type. However, in some real-world scenarios, we need more flexibility.
For example, a Task can be related to either a Contact or a Lead. In such cases, Salesforce provides something called polymorphic relationships.
In Salesforce, we have various types of relationships, including child-to-parent, parent-to-child, master-detail, and lookup. There are some scenarios where we require a deeper level of flexibility in the object relationships.
In this situation, we require polymorphic relationships that allow a child object to reference multiple parent objects of different types.
In this article, you will learn everything about polymorphic relationships in Salesforce SOQL. We will cover definitions, examples, queries, real-world use cases, and best practices so you can understand this concept clearly and apply it to real projects.
