SQL - Select Random

SELECT column1, column2, ...
FROM table_name
WHERE condition
ORDER BY RAND()
LIMIT 1;

Example:

Let's assume we have a "Tutorials" table with the following columns:

TutorialID (unique identifier for each tutorial)

Title (title of the tutorial)

IsFull (1 if the tutorial is complete, 0 if it's not complete)

Details (detailed content of the tutorial)

To select a random full detailed tutorial, we can use the following query:

SELECT TutorialID, Title, Details
FROM Tutorials
WHERE IsFull = 1
ORDER BY RAND()
LIMIT 1;

Explanation:

The SELECT statement specifies the columns you want to retrieve from the table. In this case, we're selecting TutorialID, Title, and Details.

The FROM clause indicates the table from which we want to retrieve data. In this case, it's the "Tutorials" table.

The WHERE clause is used to specify a condition to filter the rows. Here, we're checking if the IsFull column is equal to 1, which indicates a full tutorial.

The ORDER BY RAND() clause is used to randomly order the rows in the result set. RAND() is a random number generator function that assigns a random value to each row, effectively randomizing the order.

Finally, the LIMIT 1 clause ensures that only one row is returned, effectively selecting a random full detailed tutorial from the result set.

By executing this query, you will retrieve the TutorialID, Title, and Details of a random full detailed tutorial from the "Tutorials" table.
