Enums
Traits
Common set of methods for date component.
A description of an SQL unary function that operates on eagerly evaluated expressions
A description of an SQL unary function that has the ability to lazy evaluate its arguments
Common set of methods for time component.
A timestamp with both a date and a time component, but not necessarily a timezone component.
Functions
Constructs a new multidimensional array out of an arbitrary number of lower-dimensional arrays.
Constructs a new zero or one dimensional array out of an arbitrary number of scalars.
Casts between two list types by casting each element of a (“list1”) using
cast_expr and collecting the results into a new list (“list2”).
Parses a named timezone like EST or America/New_York, or a fixed-offset timezone like -05:00.
Converts the time datum b, which is assumed to be in UTC, to the timezone that the interval datum a is assumed
to represent. The interval is not allowed to hold months, but there are no limits on the amount of seconds.
The interval acts like a chrono::FixedOffset, without the -86,400 < x < 86,400 limitation.
Converts the timestamp datum b, which is assumed to be in the time of the timezone datum a to a timestamptz
in UTC. The interval is not allowed to hold months, but there are no limits on the amount of seconds.
The interval acts like a chrono::FixedOffset, without the -86,400 < x < 86,400 limitation.
Converts the UTC timestamptz datum b, to the local timestamp of the timezone datum a.
The interval is not allowed to hold months, but there are no limits on the amount of seconds.
The interval acts like a chrono::FixedOffset, without the -86,400 < x < 86,400 limitation.
Converts the time t, which is assumed to be in UTC, to the timezone tz.
For example, EST and 17:39:14 would return 12:39:14.
Converts the timestamp dt, which is assumed to be in the time of the timezone tz to a timestamptz in UTC.
This operation is fallible because certain timestamps at timezones that observe DST are simply impossible or
ambiguous. In case of ambiguity (when a hour repeats) we will prefer the latest variant, and when an hour is
impossible, we will attempt to fix it by advancing it. For example, EST and 2020-11-11T12:39:14 would return
2020-11-11T17:39:14Z. A DST observing timezone like America/New_York would cause the following DST anomalies:
2020-11-01T00:59:59 -> 2020-11-01T04:59:59Z and 2020-11-01T01:00:00 -> 2020-11-01T06:00:00Z
2020-03-08T02:59:59 -> 2020-03-08T07:59:59Z and 2020-03-08T03:00:00 -> 2020-03-08T07:00:00Z
Converts the UTC timestamptz utc to the local timestamp of the timezone tz.
For example, EST and 2020-11-11T17:39:14Z would return 2020-11-11T12:39:14.
