I want Tips for Improving SQL Server's Slow Queries

Hey All,

I am working on a few queries in SQL Server that seem to be taking a bit longer than expected to execute.

Also I have tried some basic optimization techniques like adding proper indexing & reviewing execution plans but the performance gains have not been as significant.
Are there any advanced optimization strategies or tools you suggest for identifying and fixing slow queries? Maybe there are some specific settings within SQL Server itself
I am also using Python to automate some database tasks. Are there any Python libraries or tools that can help with SQL Server optimization and performance monitoring?

As well, I found these resources when doing research on this; Migrating from SQL Server 2014 to 2022 & if anyone have any resources, tutorials or personal experiences please share with me, It would be greatly appreciated!!

Thank you……. :slight_smile:

What did you see in the execution plans? What is your benchmark to decide that the query is slow?
There are many things to check like the table design using correct datatypes, any conversions used in the query, up to date statistics etc..

Query tuning typically involves indexing. But would need to see the table DDL and the index stats to provide any specific details on how to tune your particular tables.

I recommend you start by watching this video to get started with understanding what changes you can make to your queries and what indexes you can create to increase query efficiency.

There is nothing an external tool or library can do to help. Learn how the engine processes queries and makes use of indexes, and you'll be on your way to success.

Besides that, all I can do is repeat the request for a lot more information... the query, the table schema, the execution plan, etc.
