Question
Which of the following is the correct order of keywords for SQL SELECT statements?
Solution
The correct order of keywords for SQL SELECT statements is as follows:
-
SELECT: This keyword is used to specify the columns or expressions that you want to retrieve from the database.
-
FROM: This keyword is used to specify the table or tables from which you want to retrieve the data.
-
WHERE: This keyword is used to specify the conditions that the retrieved data must meet. It is optional, but it allows you to filter the data based on specific criteria.
-
GROUP BY: This keyword is used to group the retrieved data based on one or more columns. It is often used in combination with aggregate functions like SUM or COUNT.
-
HAVING: This keyword is used to specify conditions that the grouped data must meet. It is similar to the WHERE keyword, but it operates on the grouped data rather than individual rows.
-
ORDER BY: This keyword is used to sort the retrieved data based on one or more columns. It can be used in ascending (ASC) or descending (DESC) order.
-
LIMIT: This keyword is used to limit the number of rows returned by the SELECT statement. It is often used in combination with the ORDER BY keyword to retrieve a specific number of top or bottom rows.
So, the correct order of keywords for SQL SELECT statements is: SELECT, FROM, WHERE, GROUP BY, HAVING, ORDER BY, LIMIT.
