Home -> Community -> Usenet -> c.d.o.server -> Re: Chained Rows VS new extent allocation
On insert Oracle will put the row in a block where it fits. So if there is
not enough room in a block then it will put it in a new block. If the row
is larger than a block then it will chain it because there isn't any choice.
Chaining occurs when rows are updated and become too large to fit into a
block.
