Hi All,

In my below query creating duplicate records.

SelectMem.*, 2011.[STATUS]as[2011_STATUS], 2012.[STATUS]as[2012_STATUS], 2013.[STATTUS]as[2013_STATUS]

          from  FINALmemleft outerjoin

        YEAR_2011 2011 onleft(mem.ROW_ID,'30') =left(2011.ROW_ID,'30')

        leftouterjoin

        YEAR_2012 2012 onleft(mem.ROW_ID,'30') =left(2012.ROW_ID,'30')

        leftouterjoin

 YEAR_2013 2013 onleft(mem.ROW_ID,'30') =left(2013.ROW_ID,'30')

YEAR_2011,2012,2013 tables have only 2 columns ROW_ID,STATUS
