How to delete null values in SQL?

Question

Can anyone explain how to delete null values in SQL?

Answer 1

We can use the Null operator to check for null values in that particular column and delete those records using the DELETE command. Here is the SQL query to delete null values in SQL:

DELETE FROM Table_name

WHERE column_name  = ‘   ’

or

DELETE FROM Table_name

WHERE column_name  IS NULL

Answer 2

To delete all the null values in Sql, DELETE statement combined with WHERE clause will work.

Here’s the query that you can use:

DELETE FROM table_name

WHERE column_name IS NULL;

For multiple columns:

DELETE FROM table_name

WHERE column1 IS NULL OR column2 IS NULL;
