CREATE TABLE SYS_SCHEDULED_EVENT(
    SE_NAME             varchar,
    SE_START            datetime,
    SE_SQL              varchar,
    SE_LAST_COMPLETED   datetime,
    SE_INTERVAL         integer,
    PRIMARY KEY(SE_NAME));

This table describes each scheduled SQL command. SE_NAME is the name of the scheduled event. SE_START is the first schedule execution time. SE_SQL is the text of the SQL command to be executed. SE_LAST_COMPLETED is the last time when the SQL command was executed successfully. SE_INTERVAL is the interval between the runs of the SQL command in minutes.

Defining a new scheduled event means adding a row to the SYS_SCHEDULED_EVENT with an insert statement like this:

INSERT INTO SYS_SCHEDULED_EVENT (SE_NAME, SE_SQL, SE_START, SE_INTERVAL)
                VALUES (.....)
