Contents
The<segmentation>
container is used by the
addtab
transaction to segment tables along the specified columns.Example
<segmentation cols="col1"> <advise [sort="1"] cols="col1"/> </segmentation>
The cols
attribute of <segmentation>
specifies the
columns to segment along. The <segmentation>
block can contain any
number of <advise>
tags. Each advise tag indicates that a particular
sequence of columns is also sortseg or segby, given the segmentation enforced in the
<segmentation>
tag’s cols
attribute. For example, if
you have your table segby "day"
, then it is probably also segby
"month"
.
