You could refer to the Working with Recurrence Appointments
help article, which shows how recurring appointments are added, from code-behind.
Also, if you want to insert an appointment into the data base, with recurrence rule defined for it, using SQL query, you could use the following example:
Appointments(Subject, Start, [
], UserID, RoomID, RecurrenceRule,
Description, Reminder, LastModified)
When you insert a RecurrenceRule value make sure that there are no new lines or double spaces left. The value should be just as in the example above.
As for the RecurrenceRule presentation as a three-line string on pasting, it probably depends on the environment where you are pasting the string.
I hope this helps.
