declare @table table (    pid integer,    medicine varchar(10)  )  insert @table values (1, 'abc') insert @table values (2, 'abc') insert @table values (1, 'def') insert @table values (2, 'def') insert @table values (1, 'ghi')    select distinct a.pid,                 medicine = stuff((select ',' + b.medicine                                     @table b                                     a.pid = b.pid                                       xml path('')),1,1,'') @table

result:

**pid   medicine** 1   abc,def,ghi 2   abc,def
