There is no fast way to split an existing table into partitions. Create a new parent table, create partitions, create the insert trigger, and then INSERT INTO newparent SELECT * FROM unpartitioned. You may want to split that into groups if you have many millions of rows.

Hi,
I have a question concerning the topic patitioning.
I have a table with millions of records and I would like to partition it. I have already read the documentation but it could not answer my question.
My question is, the following:
Do I have to create the master and child tables and so on before inserting the data or is it also possible to partition a table which already contains millions of records??? And how can I do this??? Has anybody done this before???
Thanks.
Andi
