How to Optimize SQL Query? Hope now you feel that optimizing a query is better also there are a few things that you have to consider before writing a query or before deploying the same. Avoid using “*” in select query We have the habit of always writing a query using “*” in sele...
doing SQL query optimization is tricky, but necessary practice for database professionals. It requires looking at various collections of data using execute the plan, CPU utilization, and CPU memory consumption. Sometimes some queries are expensive to execute. To prevent this some solutions are ...
Use the specific SQL syntax for creating a non-clustered index according to your DBMS. After implementing the index, monitor query performance and adjust the index as necessary to optimize speed and resource usage.-- SQL Server CREATE NONCLUSTERED INDEX IX_Country ON Customers (Country);Creating...
Hi all, I have a stored procedure query that is going to timeout on the production server for some time. However, I am not sure how to fix this query issue. I have 12 years old data in sql database those data fetching from this query, day by day my data is increasing o...

By avoiding SELECT DISTINCT and using GROUP BY instead, you can optimize SQL queries and reduce the total query time from 198 to 62 msec which is more than 3 times faster. Avoid Using Loops Loops might cause your query to be slower since they force the database to go through the records...
Parameterization is a technique used to optimize query performance by reusing query execution plans. When a parameterized query is executed, SQL Server can reuse the query execution plan instead of creating a new one each time the query is executed. This can significantly improve query performance,...
Once you detect what parts need performance improvements, you can move to the query optimization process. In the next section, we explore how to optimize a query using an execution plan in SQL Server.Read also Python Libraries for Database Management: Detailed Overview and Performance Comparison ...
