In SQL, a NULL value represents a missing or unknown value in a column. It is important to know how to properly handle NULL values in SQL queries. <\/p>\n

**To put a NULL value in SQL, you can simply use the keyword NULL in the query where you want to insert a NULL value. For example, if you want to insert a NULL value into a column called ‘age’ in a table named ‘students’, you can use the SQL statement:**<\/p>\n

“`
\nINSERT INTO students (age) VALUES (NULL);
\n“`<\/p>\n

It is also possible to update an existing column value to be NULL using the UPDATE statement. For example:<\/p>\n

“`
\nUPDATE students SET age = NULL WHERE student_id = 123;
\n“`<\/p>\n

By utilizing this keyword, you can effectively insert or update NULL values in SQL databases.<\/p>\n
