Remove a NOT NULL Constraint in Snowflake
For removing the “NOT NULL” constraint in Snowflake, we utilize the following command:
ALTER TABLE <table_name> ALTER <column_name> DROP Restate the column definition, adding “NOT NULL” Attribute
alter table products1
alter category drop not null;
Conclusion
The “ALTER TABLE” command is used for removing the “NOT NULL” constraint. I hope this information is adequate for removing the NOT NULL Constraints.
