I have an sql server  2016  table TB_Docs with fields
    DocUID,  DocID , DocName, …..

I have TB_DocAttr  with following  fields
   UID,   OBJID , PropertyVal ,  StrValue  
 
( OBJID in TB-DocAttr  is a foreign key to primary key DocUID  in TB_Docs)

sample   TB_Docs
   DocUID    DocID             DocName
    123          UID_Doc1         Doc1
    345          UID_Doc2         Doc2
    678          UID_Doc3         Doc3

 TB_DocAttr
    UID       OBJID   PropertyVal      StrVal
     111        123       Prop1                Val11
     222        123      Prop2                Val12
    333        123       Prop3                Val13
    444        345       Prop2                 Val22  
    555        345       Prop3                 Val23  
   
 I need a query that can give the properties and  values  in the same row  like this
    DocName     DocUID        Prop1         Prop2       Prop3
   Doc1                  123            Val11           Val12        Val13
   Doc2                   345                                Val22        Val23

    In Oracle I could get  the "flattening" of the properties  with  
       MAX(DECODE(p.propertyval,'Prop1',p.strvalue))             AS  Prop1,
       MAX(DECODE(p.propertyval,'Prop2',p.strvalue))             AS  Prop2
   
  How can I get it in Sql Server?
