HexStringLiteral(String)
X’hex value’
Boolean(bool)
Boolean value true or false

Timestamp(String)

literals
Interval
INTERVAL literals, roughly in the following format:
INTERVAL '<value>' <leading_field> [ (<leading_precision>) ] [ TO <last_field> [ (<fractional_seconds_precision>) ] ]
,
e.g. INTERVAL '123:45.67' MINUTE(3) TO SECOND(2)
.
The parser does not validate the <value>
, nor does it ensure
that the <leading_field>
units >= the units in <last_field>
,
so the user will have to reject intervals like HOUR TO YEAR
.
Null
NULL
value
Default
use the default value
