使用 SQL Server object catalog views :

select 
     IndexName  = i.name
   , SchemaName = schema_Name(t.schema_id)
   , TableName  = t.Name
   , ColumnName = c.Name 
   , TypeName   = type_name(c.user_type_id)
from sys.tables t
  inner join sys.indexes as i on
            t.object_id = i.object_id
        and i.is_primary_key = 1
  inner join sys.index_columns as ic on 
        i.object_id = ic.object_id
    and i.index_id = ic.index_id 
  inner join sys.columns as c on 
        c.column_id = ic.column_id
    and c.object_id = ic.object_id 
    and type_name(c.user_type_id) = 'uniqueidentifier'
