Using IS NOT NULL

The syntax for selecting non-null values using IS NOT NULL is as follows:

SELECT column_name(s)
FROM table_name
WHERE column_name IS NOT NULL;

Replace column_name(s) with the name of the column or columns you want to select from, and table_name with the name of the table you want to select from.

For example, if you have a table named customers with columns named name, email, and phone, and you want to select all rows where the phone column is not null, the query would look like this:

SELECT name, email, phone
FROM customers
WHERE phone IS NOT NULL;

This will return all rows where the phone column has a non-null value.

Conclusion

Using the IS NOT NULL operator is a simple and effective way to select non-null values in MySQL. By including this operator in your SELECT statements, you can quickly and easily filter out any rows with null values and focus on the data that you need.
