Vì sao Join table nhỏ vẫn chậm & cách xử lý | SQL Server Tuning | Trần Quốc Huy – Wecommit

Do you think that JOINing a table with few records will definitely be fast? In this video, I will prove the opposite: JOINing a small table (only 1 record) many times can make the query SLOWLY on SQL Server! I will analyze the cause from the perspective of the execution strategy of the statement (SQL Execution Plan) and share how to handle it to make the statement lightning fast. Enter and get the result immediately. I did this demo on SQL Server, but this Database optimization mindset can be applied to other types (Oracle, PostgreSQL, MySQL, MariaDB...).
