next.jdbc.date-time
Optional namespace that extends next.jdbc.prepare/SettableParameter
to various date/time types so that they will all be treated as SQL
timestamps (which also supports date and time column types) and has
functions to extend next.jdbc.result-set/ReadableColumn.
Simply requiring this namespace will extend the SettableParameter protocol
to the four types listed below.
In addition, there are several read-as-* functions here that will
extend next.jdbc.result-set/ReadableColumn to allow java.sql.Date
and java.sql.Timestamp columns to be read as (converted to) various
Java Time types automatically. The expectation is that you will call at
most one of these, at application startup, to enable the behavior you want.
Database support for Java Time:
- H2 and SQLite support conversion of Java Time (
Instant,LocalDate,LocalDateTime) out of the box, - Nearly all databases support conversion of
java.util.Dateout of the box -- except PostgreSQL apparently!
Types supported by this namespace:
java.time.Instantjava.time.LocalDatejava.time.LocalDateTimejava.util.Date-- mainly for PostgreSQL
PostgreSQL does not seem able to convert java.util.Date to a SQL
timestamp by default (every other database can!) so you'll probably
need to require this namespace, even if you don't use Java Time, when
working with PostgreSQL.

Simply requiring this namespace will extend the `SettableParameter` protocol to the four types listed below. In addition, there are several `read-as-*` functions here that will extend `next.jdbc.result-set/ReadableColumn` to allow `java.sql.Date` and `java.sql.Timestamp` columns to be read as (converted to) various Java Time types automatically.

read-as-defaultclj
(read-as-default)After calling this function, next.jdbc.result-set/ReadableColumn
will be extended to java.sql.Date and java.sql.Timestamp so that any
date or timestamp columns will be read as-is. This is provided for
completeness, to undo the effects of read-as-instant or read-as-local.
After calling this function, `next.jdbc.result-set/ReadableColumn` will be extended to `java.sql.Date` and `java.sql.Timestamp` so that any date or timestamp columns will be read as-is. This is provided for completeness, to undo the effects of `read-as-instant` or `read-as-local`.
read-as-instantclj
(read-as-instant)After calling this function, next.jdbc.result-set/ReadableColumn
will be extended to (java.sql.Date and) java.sql.Timestamp so that any
timestamp columns will automatically be read as java.time.Instant.
Note that java.sql.Date columns will still be returned as-is because they
cannot be converted to an instant (they lack a time component).
After calling this function, `next.jdbc.result-set/ReadableColumn` will be extended to (`java.sql.Date` and) `java.sql.Timestamp` so that any timestamp columns will automatically be read as `java.time.Instant`. Note that `java.sql.Date` columns will still be returned as-is because they cannot be converted to an instant (they lack a time component).
read-as-localclj
(read-as-local)After calling this function, next.jdbc.result-set/ReadableColumn
will be extended to java.sql.Date and java.sql.Timestamp so that any
date or timestamp columns will automatically be read as java.time.LocalDate
or java.time.LocalDateTime respectively.
After calling this function, `next.jdbc.result-set/ReadableColumn` will be extended to `java.sql.Date` and `java.sql.Timestamp` so that any date or timestamp columns will automatically be read as `java.time.LocalDate` or `java.time.LocalDateTime` respectively.
