MySQL IS NOT NULL: Usage & Examples

In MySQL, you can utilize IS NOT NULL to check if a field or expression is not empty. This condition can be used in the WHERE clause of a SELECT statement to filter out non-empty records.

Here is an example query that demonstrates how to use the IS NOT NULL function in MySQL to check if a field is not empty:

SELECT * FROM table_name
WHERE column_name IS NOT NULL;

In the example above, table_name represents the name of the table, while column_name represents the field name to check for non-null values. This query will return all the records in the table_name table where the column_name field is not empty.

By using the IS NOT NULL function, you can easily filter out non-empty data records in MySQL to meet specific query requirements.
