Good morning, I have a small doubt regarding a partitioned table, which has its "mother" table and many "daughter" tables, well the main question is... I need to reduce the size of my partitioned table, I can simply delete ( drop table) the oldest daughter tables??? or it is not recommended....or maybe there is another method to do this??
Detaching and dropping will (as mentioned by Holger) certainly reduce the size of your partitioned table.
Remember, though, that you might have partitioned the table by some other key besides a date field.
