SOQL (Salesforce Object Query Language) is a powerful tool for querying Salesforce data. Adhering to best practices ensures optimal performance, security, and maintainability. Here are the top five SOQL best practices:
Make SOQL selective by using at least one query filter on the index field. Below fields are the index fields that we should use in the filter
1. Primary Keys
2. Foreign Keys
3. External Ids
4. Record Type
5. Audit Field and
6. Unique Field
Avoid null values in the Salesforce Query condition. Null values make a full table scan that will impact performance.
Use SOQL for loop to query large data sets. SOQL for loop will fetch a batch of 200 records batch once and keep iterating.
Executing the SOQL query in the for loop will make a new call to the server for each loop iteration, making the application slow.
Limit query results based on your requirements. Some time query returns 1000 records and we need only 1 record to process.
