SEARCHSTATE.ADDRANGECONSTRAINT
Adds a range constraint for a specific attribute name.
Syntax
<SEARCHSTATE.ADDRANGECONSTRAINT
NAME="ssname
" [BUCKET="bucketname
"] [TYPENAME="assettype
"] ATTRIBUTE="attribname
" LOWER="lowrange
" UPPER="uprange
" [CASEINSENSITIVE="true|false
"] />Parameters
NAME
(required)- Input parameter. Name of an object representing a searchstate.
BUCKET
(optional)- Input parameter. Bucket name. If not specified, the attribute name is used. Use this parameter to indicate which constraint you need when the same attribute is used in multiple contstraints. A bucket is an alias and functions similar to an inner join in SQL; when you have multiple tables that have columns of the same name, you must specify the table name to indicate which column you are requesting.
TYPENAME
(optional)- Input parameter. The internal asset name for the attribute (either
CAttributes
for content attribute, orPAttributes
for product attribute). If you do not specifyTYPENAME
, a value is supplied from a property in thegator.ini
property file:mwb.defaultattributes=PAttributes.
The default value is set to bePAttributes
and may be changed to be the name of any custom attribute asset types you create.
ATTRIBUTE
(required)- Input parameter. Name of the attribute to constrain.
LOWER
|LOWEREQUAL
(required)- Input parameter. The bottom end of the range.
UPPER
|UPPEREQUAL
(required)- Input parameter. The top end of the range.
CASEINSENSITIVE (optional)
- Input parameter. A Boolean value:
true
indicates that the comparison is case-insensitive;false
(the default) considers case in the comparison.
Error Numbers
The possible values of
errno
include:
Value Description -10004 A required parameter is missing. -13050 General error.Example
This code creates an empty
SEARCHSTATE
and adds a range constraint. The constraint setsupper
andlower
limits on theattribute
being searched on. Thetypename
parameter is not specified and the default set in gator.ini is picked up. Any assets with values for this attribute in that range will be returned as matches for this constraint. This code then sets thisSEARCHSTATE
into anASSETSET.SETSEARCHEDASSETS
tag to constrain theASSETSET
to be used when searching with other assetset tags. The last tag uses this constrained assetset to search for matching assets and fetch a list of actual values for theattribute
of the returned assets:<SEARCHSTATE.CREATE NAME="ss" /> <SEARCHSTATE.ADDRANGECONSTRAINT NAME="ss" ATTRIBUTE="price" UPPER="3" LOWEREQUAL="2"/> <ASSETSET.SETSEARCHEDASSETS NAME="as" CONSTRAINT="ss" ASSETTYPES="Products"/> <ASSETSET.GETATTRIBUTEVALUES NAME="as" ATTRIBUTE="price" LISTVARNAME="resultlist"/> <LOOP LIST="resultlist"> <CSVAR NAME="resultlist.value"/><br/> </LOOP>See Also
