![]() ![]() Then, we update the top_supplier column for the records whose corresponding IDs are found in the list created by the subquery. Use this keyword in a subquery to get the IDs of the top 10 suppliers: ![]() Unlike MySQL, SQL Server does not have the LIMIT keyword. Use the same syntax to update only the first row, or the first 5, 20, 100, or any number of rows by simply changing the number after the LIMIT keyword. As you see, only the top 10 suppliers have “Yes” in the last column. ![]() Here’s the updated table ordered by volume_2021. If you need to refresh your knowledge of ORDER BY, check out this detailed article. So, we order the table based on the volume_2021 column (in descending order), and then limit the number of rows to be updated to 10. However, we want these updates for the top 10 suppliers only. With this query, we update the suppliers table by setting the value of the top_supplier column to “Yes”. In MySQL, we can leverage the LIMIT keyword that limits the number of records to output or to update: For now, I’ll show you working queries for a few of the most popular database management systems. The syntax of the query to accomplish this third step depends on the database management system (e.g., MySQL, SQL Server, Oracle, or PostgreSQL). Now comes the most interesting part: updating the top_supplier column for the first 10 rows after we order the table by the volume_2021 column. Here’s how we can accomplish the first two steps:Īnd here is the resulting table: suppliers
