([] of Int32).first # raises Enumerable::EmptyError

def self.first? : T | Nil #

def self.truncate(*, cascade : Bool = false) #

Removes all data from a table using the TRUNCATE postgres SQL command.

You should run this command with cascade: true if your table columns are referenced by other foreign key constraints. Use delete instead if you don't want to accidentally delete rows referenced elsewhere.

To delete all data referenced by foreign keys as well, set cascade to true.
