Scenario: In Entity Framework, you need to update a record only if it meets certain conditions. How can you achieve this while updating data in EF?

  • Fetch all records and filter them programmatically in C# code before updating the necessary record.
  • Manually check conditions in C# code after retrieving the record and before updating it.
  • Update all records and then revert changes for records that do not meet the specified conditions.
  • Use the Where method in LINQ query to filter records based on conditions before updating.
In Entity Framework, to update a record only if it meets certain conditions, you can use the Where method in LINQ query to filter records based on conditions before performing the update operation. This ensures that only the records meeting the specified criteria are updated, minimizing unnecessary database operations. Fetching all records and filtering them programmatically or updating all records and then reverting changes are inefficient and prone to errors. Manually checking conditions in C# code introduces unnecessary complexity and reduces maintainability.
