Learn Step By Step Explanation of Indexes and Execution Plans using T-SQL Commands in Microsoft SQL Server
What you'll learn
Participants will get deeper knowledge on Clustered ,Non Clustered Indexes & Fragmentation Concepts
Participants will learn commonly used Execution Plans
Participants will learn to find the patterns which may be slowing down the query performance
This course will Help Participant to tune already written query or write T-SQL in a better way
Requirements
RDBMS concepts should be known & should have good hands-on on T-SQL Commands
SQL Server 2022 (lower version can work also) and SQL Server Management Studio should be installed already
Description
