To create a transaction-time table, use a normal CREATE TABLE statement, and define one column of the table as a transaction-time column. The data type of the column can be derived from two TIMESTAMP(6) WITH TIME ZONE columns, or can be a single PERIOD(TIMESTAMP(6) WITH TIME ZONE) column, and must use the TRANSACTIONTIME or AS TRANSACTIONTIME column attribute. Transaction-time columns must also specify the NOT NULL column attribute.
Example: Creating a Derived Period Transaction-Time Table
CREATE MULTISET TABLE Policy_Types ( Policy_Name VARCHAR(20), Policy_Type CHAR(2) NOT NULL PRIMARY KEY, Policy_Start TIMESTAMP(6) WITH TIME ZONE NOT NULL, Policy_End TIMESTAMP(6) WITH TIME ZONE NOT NULL, PERIOD FOR Policy_Duration(Policy_Start,Policy_End) AS TRANSACTIONTIME ) PRIMARY INDEX (Policy_Name);
Example: Creating a Period Data Type Transaction-Time Table
CREATE MULTISET TABLE Policy_Types ( Policy_Name VARCHAR(20), Policy_Type CHAR(2) NOT NULL PRIMARY KEY, Policy_Duration PERIOD(TIMESTAMP(6) WITH TIME ZONE) NOT NULL AS TRANSACTIONTIME ) PRIMARY INDEX (Policy_Name);
