How can the low efficiency of sorting after creating a view in SQL Server be resolved?

If a view created in SQL Server has low efficiency during sorting, you can try the following methods to resolve it:

1. Index optimization: Make sure there are appropriate indexes on relevant columns to be able to retrieve and sort data faster during sorting. You can use SQL Server’s Index Tuning Wizard to analyze and add suitable indexes for columns in the view.
2. Partitioning: if the tables in the view are very large, it may be helpful to partition the tables so that only the necessary partition data is processed during sorting, thereby improving sorting efficiency.
3. Data compression: If the data in the tables in the view is large, consider using SQL Server’s data compression feature to reduce storage space and improve read performance.
4. Optimize queries by reviewing the definition of views and query statements to ensure they only retrieve necessary columns and rows. Consider restructuring queries to improve sorting operations.
5. Update database statistics: Regularly updating the statistics in the database will allow SQL Server to make better optimization decisions when executing queries.
6. Consider using temporary tables if the query in the view involves complex sorting operations, storing the query results in a temporary table and performing the sorting operation on the temporary table may be a good option.
7. Consider upgrading the version of SQL Server: If you are currently using an older version of SQL Server, it may be worth upgrading to a newer version in order to improve sorting performance and optimization features.

The appropriate method should be chosen based on specific circumstances, followed by proper testing and performance optimization.
