Yes, indexing fields in a table can enhance the speed of select queries. When a field is indexed, the database engine creates a data structure that allows faster searching and sorting. When a query is executed that includes the indexed field, the database engine can use the index to quickly find the relevant data instead of doing a full table scan. This can significantly improve the performance of queries, especially when dealing with large datasets. However, indexing every field may not always be the best solution, as it can also slow down the speed of insert, update and delete operations. It is important to evaluate the specific requirements and usage patterns of a database to determine which fields should be indexed.
