Thank you so much for the clear and concise explanation. I really found it hard to understand these isolation levels without actually seeing it in action and you provided clear examples while explaining it. Very useful!
The right order of playlist 1- MSSQL - Overview of the Isolation Level Videos 2- MSSQL - Understanding Isolation Level by Example (Read Uncommitted) 3- MSSQL - Difference Between Dirty Read and Phantom Read 4- MSSQL - Understanding Isolation Level By Example (Repeatable Read) 5- MSSQL - Understanding Isolation Level By Example (Serializable) 6- MSSQL - Understanding Isolation Level By Example (Snapshot) Great Explanation ❤
Thank you. In case you are still here, and can answer my question: If you have an open transaction that's updating a table and you run a SELECT * query, and we are using a read committed isolation level, the query will block. I get it. But what if the SELECT query was run before the UPDATE transaction began? Let's say you have a really large table with a million rows and the SELECT query takes a minute to run. Will the UPDATE transaction block in this case? Thank you :)
