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).
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.
- 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:
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.

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.

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 returns 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`.

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.
