Provide examples of common SQL aggregate functions and their use cases.
I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

COUNT():
SUM():
AVG():
MAX():
MIN():
GROUP_CONCAT() (or equivalent functions like STRING_AGG() in SQL Server, LISTAGG() in Oracle):
SUM() with GROUP BY:
AVG() with HAVING:
COUNT() with DISTINCT:
COUNT() with CASE:
These aggregate functions are fundamental in SQL and are used extensively for summarizing and analyzing data in databases. Depending on your specific data analysis needs, you can choose the appropriate aggregate function to retrieve the desired information from your database tables.
