Using Java 8 Date and Time classes

The PostgreSQL™ JDBC driver implements native support for the Java 8 Date and Time API (JSR-310) using JDBC 4.2.

Table 5.1. Supported escaped numeric functions

PostgreSQL™ Java SE 8
DATE LocalDate
TIME [ WITHOUT TIMEZONE ] LocalTime
TIMESTAMP [ WITHOUT TIMEZONE ] LocalDateTime
TIMESTAMP WITH TIMEZONE OffsetDateTime

This is closely aligned with tables B-4 and B-5 of the JDBC 4.2 specification. Note that ZonedDateTime, Instant and OffsetTime / TIME [ WITHOUT TIMEZONE ] are not supported. Also note that all OffsetDateTime will instances will have be in UTC (have offset 0). This is because the backend stores them as UTC.

Example 5.5. Reading Java 8 Date and Time values using JDBC

Statement st = conn.createStatement();
ResultSet rs = st.executeQuery("SELECT * FROM mytable WHERE columnfoo = 500");
while (rs.next())
{
    System.out.print("Column 1 returned ");
    LocalDate localDate = rs.getObject(1, LocalDate.class));
    System.out.println(localDate);
}
rs.close();
st.close();

For other data types simply pass other classes to #getObject. Note that the Java data types needs to match the SQL data types in table 7.1.

Example 5.5. Writing Java 8 Date and Time values using JDBC

LocalDate localDate = LocalDate.now();
PreparedStatement st = conn.prepareStatement("INSERT INTO mytable (columnfoo) VALUES (?)");
st.setObject(1, localDate);
st.executeUpdate();
st.close();
