What are DQL commands?

DQL or Data Query Language commands are used for querying data from database objects. This is only a single command which can result in records from dbo such as tables, views etc and can be subject to projection.

SELECT [ DISTINCT column_1, column_2 .. | * ]
FROM <table_name>
WHERE <query_condition>
GROUP BY <columns_list>
HAVING <condition>
ORDER BY <columns_list> [ ASC | DESC ]
