AX Queries – Passing query range as parameter

Following is code for paramterized query. ie. query range passed as set of container values:

static FreeText
FindEngineerByTradeArea(NoYes    _skillRestriction = NoYes::No,
MxmServTradeId   _tradeCriteria = “”,
NoYes
_areaRestriction = NoYes::No,

MxmServAreaId     _areaCriteria = “”,
MxmServProficiency     _tradeProficiency =
MxmServProficiency::Primary,
MxmServPreference      _areaPreference   =
MxmServPreference::Primary
)

{
MxmServEngineerTrade
localtrade;
MxmServEngineerArea
localArea;
MxmServEngineer
engineer;
