write up in couple of lines on error fixed

Core Answer

The error “Too many SOQL queries” occurs when code exceeds the Salesforce governor limit of 100 SOQL queries in a single transaction. This was fixed by implementing query optimization techniques including query consolidation, bulkification, and strategic use of collections.

Reasons and Explanations

• Reason 1: Moved SOQL queries outside of loops by using collections (Maps and Lists) to store and reference data, preventing repetitive database calls for the same information.
• Reason 2: Implemented bulkification patterns by retrieving all needed records in a single query rather than querying one record at a time, significantly reducing the number of queries executed.
• Reason 3: Used selective queries with appropriate filters to retrieve only necessary data, reducing both query count and processing overhead.
• Reason 4: Applied the Aggregate-Query-Update pattern to consolidate related operations, minimizing the need for separate queries for related records.

Summary

The “Too many SOQL queries” error was resolved by restructuring code to use fewer, more efficient queries through techniques like bulkification, query consolidation, and proper use of collections. This optimization not only fixed the immediate error but also improved overall application performance and scalability by reducing database interactions.
