![]() It is used to group the rows that have the same values. The following comparison chart explains their main differences in a quick manner: SN On the other hand, ORDER BY is always used after the GROUP BY statement. GROUP BY is always placed after the WHERE clause but before the ORDER BY statement.In contrast, the ORDER BY clause controls the presentation of columns that means the ordering or sorting is done based on the column's attribute values either in ascending or descending order. Group By clause controls the presentation of tuples that means grouping is done based on the similarity among the row's attribute values.The attribute cannot be under GROUP BY statement under aggregate function, whereas the attribute can be under ORDER BY statement under aggregate function.On the other hand, it's not mandatory to use the aggregate function to use the Order By. It is mandatory to use the aggregate function to use the Group By.The ORDER BY clause, on the other hand, sorts the result and shows it in ascending or descending order. The Group By clause is used to group data based on the same value in a specific column.The following are the key distinctions between the Group By and Order By clause: Next, the AVG function is performed on each group of states, then sort the result in descending order, and finally, we will get the desired results as shown below: Key Differences between GROUP BY and ORDER BY This query initially formed an intermediate result that has grouped the state. Mysql> SELECT D_state, avg(D_salary) AS salary The following is the syntax to use GROUP BY clause in a SQL statement: The query for the GROUP BY clause is grouped query, and it returns a single row for each grouped object. As a result, the GROUP BY clause is always used in conjunction with the SELECT clause. ![]() If we do so, the query would be incorrect. It's important to remember that the attribute in this clause must appear in the SELECT clause, not under an aggregate function. We can often use this clause in collaboration with aggregate functions like SUM, AVG, MIN, MAX, and COUNT to produce summary reports from the database. Additionally, it is paced before the ORDER BY clause. It is always to remember that we have to place the GROUP BY clause after the WHERE clause. Usually, we use it with the SELECT statement. The GROUP BY clause is used in SQL queries to organize data that have the same attribute values. Here is the output where we will get the desired results: GROUP BY Clause The following is the syntax to use the ORDER BY clause in a SQL statement: ASC denotes ascending order, while DESC denotes descending order. The ORDER BY clause, like the GROUP BY clause, could be used in conjunction with the SELECT statement. If we omit the sorting order, it sorts the summarized result in the ascending order by default. The ORDER BY clause is used in SQL queries to sort the data returned by a query in ascending or descending order. Before making the comparison, we will first know these SQL clauses. The ORDER BY clause is applicable when we want to get the data obtained by a query in the sorting order. The main difference between them is that the GROUP BY clause is applicable when we want to use aggregate functions to more than one set of rows. ![]() The difference between these clauses is one of the most common places to get stuck when learning SQL. They are mainly used for organizing data obtained by SQL queries. This article explains the complete overview of the GROUP BY and ORDER BY clause.
