Hi @Rohith thammali When working with thousands of records in Apex, writing efficient SOQL queries is very important to avoid governor limits.
A few best practices I follow:
- Avoid SOQL inside loops. Query records once and process them using collections.
- Fetch only required fields. Avoid unnecessary fields and records.
- Use WHERE conditions to filter records efficiently, preferably using indexed fields.
- Use Maps and Sets to handle bulk records and avoid repeated queries.
- Use Batch Apex when processing large data volumes.
- Use LIMIT carefully. It's useful when you need only a specific number of records, not when you must process everything.
Also, remember that synchronous Apex generally allows 100 SOQL queries and 50,000 queried rows per transaction.
Focus on bulkification, selective queries, and proper collection usage. These make a big difference in real-time projects.
Hope this helps!
