25.7 SDO_GCDR.GEOCODE_ADDR

Format

SDO_GCDR.GEOCODE_ADDR(
     gc_username IN VARCHAR2, 
     address     IN SDO_GEO_ADDR 
     ) RETURN SDO_GEO_ADDR;

Description

Geocodes an input address using attributes in an SDO_GEO_ADDR object, and returns the first matched address as an SDO_GEO_ADDR object.

Parameters

gc_username: Name of the user that owns the tables containing the geocoding data.
address: An SDO_GEO_ADDR object with one or more attributes set. The SDO_GEO_ADDR type is described in SDO_GEO_ADDR Type.

Usage Notes

This function enables you to specify as many attributes in the input SDO_GEO_ADDR object as you can or want to set. It finds the first matching address, and returns an SDO_GEO_ADDR object with all possible attributes set.

Unlike the SDO_GCDR.GEOCODE function, which geocodes input addresses specified by unformatted address lines, the SDO_GCDR.GEOCODE_ADDR function input addresses specified by individual addressing fields defined in SDO_GEO_ADDR objects. When you use unformatted address lines, you rely on the geocoding software to parse the input address and decompose it into individual address fields. This process usually works well, but it can produce undesirable results if the input addresses are not well formatted. By contrast, when you specify parts of the input address as SDO_GEO_ADDR object attributes, you can reduce the chance of geocoding errors and produce more desirable results.

For examples of the SDO_GCDR.GEOCODE_ADDR function, see Example 12-2 and Example 12-3 in Geocoding from a Place Name.

See also the SDO_GCDR.GEOCODE_ADDR_ALL function, which performs the same operation as this function, but which can return more than one address.

Examples

The following example returns the geocoded result for a point of interest named CALIFORNIA PACIFIC MEDICAL CTR. The example uses a user-defined function named create_addr_from_placename (as defined in Example 12-2 in Geocoding from a Place Name) to construct the input SDO_GEO_ADDR object.

SELECT sdo_gcdr.geocode_addr('SCOTT', 
  create_addr_from_placename('CALIFORNIA PACIFIC MEDICAL CTR', 'US')) 
FROM DUAL;

SDO_GCDR.GEOCODE_ADDR('SCOTT',CREATE_ADDR_FROM_PLACENAME('CALIFORNIAPACIFICME

25.8 SDO_GCDR.GEOCODE_ADDR_ALL

Format

SDO_GCDR.GEOCODE_ADDR_ALL(
     gc_username  IN VARCHAR2, 
     address      IN SDO_GEO_ADDR, 
     max_res_num  IN NUMBER DEFAULT 4000 
     ) RETURN SDO_ADDR_ARRAY;

Description

Geocodes an input address using attributes in an SDO_GEO_ADDR object, and returns matching addresses as an SDO_ADDR_ARRAY object (described in SDO_ADDR_ARRAY Type).

Parameters

gc_username: Name of the user that owns the tables containing the geocoding data.
address: An SDO_GEO_ADDR object with one or more attributes set. The SDO_GEO_ADDR type is described in SDO_GEO_ADDR Type.
max_res_num: Maximum number of results to return in the SDO_ADDR_ARRAY object. The default value is 4000.

Usage Notes

This function enables you to specify as many attributes in the input SDO_GEO_ADDR object as you can or want to set. It finds matching addresses (up to 4000 or the limit specified in the max_res_num parameter), and returns an SDO_ADDR_ARRAY object in which each geocoded result has all possible attributes set.

This function performs the same operation as the SDO_GCDR.GEOCODE_ADDR function, except that it can return more than one address. See the Usage Notes for the SDO_GCDR.GEOCODE_ADDR function for more information.

Examples

The following example returns up to three geocoded results for a point of interest named CALIFORNIA PACIFIC MEDICAL CTR. (In this case only one result is returned, because the geocoding data contains only one address matching that point of interest.) The example uses a user-defined function named create_addr_from_placename (as defined in Example 12-2 in Geocoding from a Place Name) to construct the input SDO_GEO_ADDR object.

SELECT sdo_gcdr.geocode_addr_all('SCOTT',

25.9 SDO_GCDR.GEOCODE_ALL

Format

SDO_GCDR.GEOCODE_ALL(
     gc_username  IN VARCHAR2, 
     addr_lines   IN SDO_KEYWORDARRAY, 
     country      IN VARCHAR2, 
     match_mode   IN VARCHAR2 
     ) RETURN SDO_ADDR_ARRAY;

Description

Geocodes all addresses associated with an unformatted address and returns the result as an SDO_ADDR_ARRAY object.

Parameters

gc_username: Name of the user that owns the tables containing the geocoding data.
addr_lines: An array of quoted strings representing the unformatted address to be geocoded. The SDO_KEYWORDARRAY type is described in SDO_KEYWORDARRAY Type.
country: Country name or ISO country code.
match_mode: Match mode for the geocoding operation. Match modes are explained in Match Modes.

Usage Notes

This function returns an object of type SDO_ADDR_ARRAY, which is described in SDO_ADDR_ARRAY Type. It performs the same operation as the SDO_GCDR.GEOCODE function; however, it can return results for multiple addresses, in which case the returned SDO_ADDR_ARRAY object contains multiple SDO_GEO_ADDR objects. If your application needs to select one of the addresses for some further operations, you can use the information about each returned address to help you make that selection.

Each SDO_GEO_ADDR object in the returned SDO_ADDR_ARRAY array represents the center point of each street segment that matches the criteria in the addr_lines parameter. For example, if Main Street extends into two postal codes, or if there are two separate streets named Main Street in two separate postal codes, and if you specify Main Street and a city and state for this function, the returned SDO_ADDR_ARRAY array contains two SDO_GEO_ADDR objects, each reflecting the center point of Main Street in a particular postal code. The house or building number in each SDO_GEO_ADDR object is the house or building number located at the center point of the street segment, even if the input address contains no house or building number or a nonexistent number.

Examples

The following example returns an array of geocoded results, each result reflecting the center point of Clay Street in all postal codes in San Francisco, California, in which the street extends. The resulting array includes four SDO_GEOR_ADDR objects, each reflecting the house at the center point of the Clay Street segment in each of the four postal codes (94108, 94115, 94118, and 94109) into which Clay Street extends.
