When constructing a filter, you can use a condition element
to make a comparison between database columns and values. On UNIX, you can also specify more
advanced conditions.
There are three condition types:
- Simple: This is used for simple comparisons and generally uses
a single condition element.
- Complex: This is used for more complex comparisons and generally
uses two or more condition elements that are linked with logical elements,
and subqueries.
- FreeForm: This is used for an arbitrary set of conditions that
are not restricted to column name and operator expressions. The FreeForm
condition allows the advanced features of the ObjectServer SQL to
be used. This condition type is available on UNIX only.
