TIMESTAMP (Timestamp)

Supported by ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The TIMESTAMP data type represents a local date time type, or java.sql.Timestamp in Java, or Types.TIMESTAMP in JDBC.

Some dialects support an explicit precision flag on this data type. If absent, the default is dialect specific.

For historic reasons, this data type was also capable of representing a TIMESTAMP WITH TIME ZONE data type in JDBC, by making complicated use of java.util.Calendar when binding the type to a java.sql.PreparedStatement, or reading it from a java.sql.ResultSet. jOOQ, however, treats it as a java.time.LocalDateTime as suggested by various methods on the type, such as Timestamp.valueOf(LocalDateTime) or, more importantly, Timestamp.valueOf(String), which is not capable of parsing time zone information.

)

Aurora Postgres, CockroachDB, DB2, Derby, DuckDB, Exasol, Firebird, H2, HSQLDB, Hana, Oracle, Postgres, Redshift, Teradata, Trino, Vertica, YugabyteDB

CREATE TABLE t (
  c timestamp
)

)
TBLPROPERTIES(
  'delta.columnMapping.mode' = 'name',
  'delta.feature.allowColumnDefaults' = 'supported'
)

Informix

CREATE TABLE t (
  c datetime year to fraction(5)
)
