Table with reserved keywords that need to be quoted. Also provide an example to make it more obvious.
|
|
|
|
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, for example:
|
|
|
|
[source, sql]
|
|
----
|
|
SELECT "AS" FROM index
