Akash R Nilugal updated CARBONDATA-3403:
----------------------------------------
    Description:
MV is not working for like and filter AND and OR queries

 

Steps:

create table brinjal (imei string,AMSize string,channelsId string,ActiveCountry string, Activecity string,gamePointId double,deviceInformationId double,productionDate Timestamp,deliveryDate timestamp,deliverycharge double) STORED BY 'org.apache.carbondata.format' ;

 

create datamap brinjal_mv_tab_nlz_aa016 on table brinjal using 'mv' as select imei,AMSize,channelsId from brinjal where ActiveCountry NOT LIKE 'US' group by imei,AMSize,channelsId;


create datamap brinjal_mv_tab_nlz_aa018 on table brinjal using 'mv' as select imei,AMSize,channelsId,ActiveCountry from brinjal where ActiveCountry ='Chinese' or channelsId =4 group by imei,AMSize,channelsId,ActiveCountry;

 

then 

select imei,AMSize,channelsId from brinjal where ActiveCountry NOT LIKE 'US' group by imei,AMSize,channelsId; and 

  select imei,AMSize,channelsId,ActiveCountry from brinjal where ActiveCountry ='Chinese' or channelsId =4 group by imei,AMSize,channelsId,ActiveCountry;

are not hitting the datamap cretaed


 private def updatePredicateList(plan: modular.Select): modular.Select = {
    // update the AttributeRefrence name, if already the name is its table name,
    // here qualifier name is gen_subsumer_,
    val updatedPlan = plan.transformExpressions {
      case ref: Attribute if ref.name.contains(CarbonCommonConstants.POINT) =>
        val newName = ref.name.substring(ref.name.lastIndexOf(CarbonCommonConstants.POINT) + 1, ref.name.length)
        AttributeReference(newName, ref.dataType)(exprId = ref.exprId, qualifier = ref.qualifier)
    }
    updatedPlan
  }
