Using calendar syntax to specify a repeating interval v16
The CREATE_JOB and CREATE_SCHEDULE procedures use Oracle-style calendar syntax to define the interval with which a job or schedule is repeated. Provide the scheduling information in the repeat_interval parameter of each procedure.
repeat_interval is a value or series of values that define the interval between the executions of the scheduled job. Each value is composed of a token, an equals sign, and the units on which the schedule executes. Separate multiple token values with a semi-colon (;).
For example, the following value defines a schedule that's executed each weeknight at 5:45:
FREQ=DAILY;BYDAY=MON,TUE,WED,THU,FRI;BYHOUR=17;BYMINUTE=45
EDB Postgres Advanced Server supports the token types and syntax described in the table.
