/**
 * TaggerGetResourcesWhere
 *
 * DESCRIPTION
 *
 * This snippet generate SQL Query that can be used in WHERE condition in getResources snippet
 *
 * PROPERTIES:
 *
 * &tags            string  optional    Comma separated list of Tags for which will be generated a Resource query. By default Tags from GET param will be loaded
 * &groups          string  optional    Comma separated list of Tagger Groups. Only from those groups will Tags be allowed
 * &where           string  optional    Original getResources where property. If you used where property in your current getResources call, move it here
 * &likeComparison  int     optional    If set to 1, tags will compare using LIKE
 * &tagField        string  optional    Field that will be used to compare with given tags. Default: alias
 * &matchAll        int     optional    If set to 1, resource must have all specified tags. Default: 0
 * &field           string  optional    modResource field that will be used to compare with assigned resource ID
 *
 * USAGE:
 *
 * [[!getResources? &where=`[[!TaggerGetResourcesWhere? &tags=`Books,Vehicles` &where=`{"isfolder": 0}`]]`]]
