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".
