Question
Which SQL clause is used to specify the order of rows in a result set?
Solution
The SQL clause used to specify the order of rows in a result set is the "ORDER BY" clause. This clause allows you to sort the results of your query in ascending (ASC) or descending (DESC) order based on the columns you specify.
Here is a step by step guide on how to use it:
-
First, you need to write your SELECT statement to choose the data you want to display. For example:
SELECT * FROM Employees. -
Then, you add the ORDER BY clause at the end of your SQL statement. For example:
SELECT * FROM Employees ORDER BY. -
Finally, you specify the column you want to sort by, and optionally whether you want the sort to be ascending or descending. For example:
SELECT * FROM Employees ORDER BY LastName ASC.
This final statement will return all data from the Employees table, sorted by the LastName column in ascending order. If you wanted to sort by multiple columns, you can separate them with a comma. For example: SELECT * FROM Employees ORDER BY LastName ASC, FirstName ASC.
