How to Filter Rows Without Null in a Column in SQL

When you need to filter out rows with null values in a particular column of your database using SQL, solution is to use the WHERE clause with the IS NOT NULL operator. This operator checks if a value is not null and returns true if it is not null. For example, if you wanted to filter out rows with null values in the name column of your database, you would use the following query:

SELECT * FROM table_name WHERE name IS NOT NULL;
