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 (.....)
