Answer 1

您无法在单个语句中更新多个表

       BEGIN TRANSACTION

       update A
       set A.published =  @published
       from table1 A 
       inner join table2 B on B.idtb1 = A.idtb1

      update B
      set B.published = @published 
      from table2 B 
      inner join table1 A on B.idtb1 = A.idtb1

      COMMIT
