================= Reserved Keywords

The following table lists all of the keywords that are reserved in Presto, along with their status in the SQL standard. These reserved keywords must be quoted (using double quotes) in order to be used as an identifier.

The use of $ as a prefix for column names is reserved. This is a convention only and it is not enforced.
