return value. If display and return values differ, then you cannot use this
facet type for this column - use the Checkbox Group facet
instead.
-
Unchecked Value - Enter the value stored in the page
item if the user unchecks the checkbox. This attribute can also be left
blank if you want to store NULL when checked. The value can be up to 255
characters long.
Note: This value is used if the page item is populated with a value
which does not match either the Checked Value or Unchecked Value.

Checkbox Group |
Displays multiple values as checkboxes, enabling the end user to select multiple
values. A list of values is required for items displayed as checkboxes. The values
corresponding to the checked boxes are stored in a single colon-delimited
string.
Note: For Yes/No checkboxes (that is, a checkbox with only one value), Oracle
recommends using a checkbox or a Switch item type.
The following example displays employee names (ename ), but returns employee numbers (empno ):
SELECT ename, empno FROM emp;

Geocoded Address |
Provides Geocoding functionality that turns a postal address to a coordinate.
Geocoding is performed by the browser using a REST request to the
Oracle Elocation Geocoding Service (https://elocation.oracle.com/elocation/home.html). In order for geocoding
to work, the user's browser must be connected to the internet.
Geocoding input data comes from other page items which are mapped to
parts of an address such as Street, House Number, Postal Code, or City. The Geocoder
displays a popup window with a list of possible matches. After choosing a match, the
item's session state value will be the address coordinate in GeoJSON format.
The Structured Address attribute determines
whether the address parts are provided to the geocoding service in a
structured or unstructured manner. Structured means that
explicit page items are mapped to address parts such as Street, Postal Code, City or
Region. A structured address has more accurate geocoding results, and also allows
for address correction to be sent back to the page item. Unstructured means
that only one item is used for the whole address and the address parts are separated
by comma. Unstructured mode does not support address corrections.
A Geocoded Address item needs at least one other input item to work and for an exact
address requires a maximum of eight input items.
If Structured Address is Off, the item maps to
only one text field or text area where end users enter address parts, separated by
comma. Following item attributes display under Settings the
Property Editor in in Page Designer:
-
Country Type - Select whether to use a static country for
geocoding, or whether to derive the country from an item. Options include:
Static or Item.
-
Country - Select the country to use for
geocoding.
-
Structured Address - Select
Off. Determines whether address parts are provided to
the geocoding service in a structured or unstructured manner.
-
Address Item - Select the item containing
unstructured address parts, separated by a comma.
-
Match Vector Item - Select a page item for
the Geocoder to return the Match Vector. The match vector is a 17-digit string
with detailed information about how each address attribute has been matched
against the data used for geocoding. See item Help for more details.
-
Trigger Geocoding - Determines when to
trigger geocoding. This includes the browser performing the REST request to the
geocoding service and showing the popup window with possible matches. Options
include: Automatic, Dynamic
Action, and jQuery Selector. See item Help
for more details.
If Structured Address is On, the following item
attributes display under Settings the Property Editor in in
Page Designer:
-
Country Type - Select whether to use a
static country for geocoding, or whether to derive the country from an item.
Options include: Static or
Item.
-
Country - Select the country to use for
geocoding.
-
Structured Address - Select
On. Determines whether address parts are provided to
the geocoding service in a structured or unstructured manner.
-

-
Match Vector Item - Select a page item
for the Geocoder to return the Match Vector into. The match vector is a
17-digit string with detailed information about how each address attribute has
been matched against the data used for geocoding. See item Help for more
information.
-
Trigger Geocoding - Determines when to
trigger geocoding. This includes the browser performing the REST request to
the geocoding service and showing the popup window with possible matches.
Options include: Automatic, Dynamic
Action, and jQuery Selector. See item
Help for more information.
Note: The Geocoded Address and Display Map items both work with
the Oracle Elocation Map Cloud service (https://maps.oracle.com/elocation/ajax/index.jsp). This service is
accessed by the browser, not by the APEX database on the server. Be aware this may result in data protection consequences
for users. The geocoding items as and display map items store a coordinate in
GeoJSON format (https://de.wikipedia.org/wiki/GeoJSON) Note
that only the "geometry" portion is used. Currently only "Point" geometries are
supported, for example:
{
"type": "Point",
"coordinates": [
13.74081,
51.05363
]
}
|
