In this example, we retrieve the top 10 records from a SQL table without specifying any condition and ORDER BY Clause.ДЄs an MCSA certified and Microsoft Certified Trainer in Gurgaon, India, with 13 years of experience, Rajendra works for a variety of large companies focusing on performance optimization, monitoring, high availability, and disaster recovery strategies and implementation. LetвЂ™s look at a few examples of the SQL Server TOP clause for table in the AdventureWorks sample database.Д®xample 1: SQL Server TOP Clause with a constant value We must use WITH TIES along with the ORDER BY Clause In this case, we can use WITH TIES to return more rows. If we do not use WITH TIES, SQL Server returns exactly 10 records while we might have more customers with a similar purchase cost. For example, we want the top 10 customers based on the purchase amount. WITH TIES: We can specify the WITH TIES clause to return more rows with values that match the last row in the result set.PERCENT: Here, we can use PERCENT value to return the percentage number of rows from total rows in the output.Expression: We can specify a numeric expression that defines the number of rows to be returned.LetвЂ™s go ahead and explore the TOP clause and its performance aspects. For this requirement, we can use TOP or ROW_Number() clauses. We require top вЂNвЂ™ customer records to satisfy the conditions. There might be many records satisfying the condition. Altaro realizes that even though all companies recognize the importance of backing up their virtual machines, some of them simply do not have the capability to acquire a proper backup solution. Suppose you have a customer table and you want to retrieve records for customers belonging to a particular country. As promised, Altaro Software, maker of Hyper-V virtual machine backup software, is releasing a Free PowerShell script to automate Hyper-V VM export. We can use the WHERE clause in a SELECT statement to limit the number of rows.

Sometimes we want to retrieve a specific number of records from the SQL table rather than retrieving all table records. This article explores the SQL Server TOP clause using various examples, along the way, we will also run through performance optimization while using the TOP clause in SQL Server.
