“ORDER BY” Clause: User can sort the data in specific order using “ORDER BY” clause. The column on which to sort data is called a sort key or a simple key. To sort the output, use an “ORDER BY” clause followed by the sort key. If the user does not specify a sort order, the output displayed in default order that is ascending order. Example: The example for “ORDER BY” clause is given below: SELECT STUDENT_ID, STUDENT_NAME, STUDENT_CREDIT FROM STUDENT ORDER BY STUDENT_CREDIT; Explanation: The above query is used to list student ID, name and credit for each student with ascending order of student credit using an “ORDER BY” clause. From the given query, the sort key is “STUDENT_CREDIT”. So, the rows are sorted in ascending order by “STUDENT_CREDIT”.

Program Plan Intro

“ORDER BY” Clause:

User can sort the data in specific order using “ORDER BY” clause.

The column on which to sort data is called a sort key or a simple key.

To sort the output, use an “ORDER BY” clause followed by the sort key.

If the user does not specify a sort order, the output displayed in default order that is ascending order.

Example:

The example for “ORDER BY” clause is given below:

SELECT STUDENT_ID, STUDENT_NAME, STUDENT_CREDIT FROM STUDENT ORDER BY STUDENT_CREDIT;

Explanation:

The above query is used to list student ID, name and credit for each student with ascending order of student credit using an “ORDER BY” clause.

From the given query, the sort key is “STUDENT_CREDIT”. So, the rows are sorted in ascending order by “STUDENT_CREDIT”.

Explanation of Solution

Most important key:

The more important column is called the most important key.

It is also called as the major sort key or the primary sort key.

Example:

The example for most important key is given below:

SELECT STUDENT_ID, STUDENT_NAME, STUDENT_CREDIT FROM STUDENT ORDER B...

Explanation of Solution

Less important key:

The less important column is called the most important key.

It is also called as the minor sort key or the secondary sort key.

Example:

The example for less important key is given below:

SELECT STUDENT_ID, STUDENT_NAME, STUDENT_CREDIT FROM STUDENT ORDER...
