A query is simply a statement you execute on a database. A sub-query is a nested query.

Query is a command for the Database to do something. Subquery is a query within another query embedded within the WHERE clause.

A query is a statement which u give and the subqueries are queries inside the query.

A good example of query might be Select * From [Table_Name] And a query with a subquery might be Select * From [Table_Name] => query Where [Column_Name or condition u wanna apply] IN (Select [column_Name] From [Table_Name] and a Where statement if you wanna apply any condition) => Subquery The subquery is between the comma i know sometimes as programmer is better to see the code than the meaning to have a better understanding. Hope its help u out
