HI,
try this.
DECLARE  @sql nvarchar(max),@clmns nvarchar(max),@table nvarchar(100),@ln varchar(max)
SET @table = 'REGIONS'
SELECT @clmns =
STUFF((
            SELECT ', ['+name+']' as 'data()' FROM
                    SELECT name FROM sys.columns where object_id = object_id(@table)
                ) a
            FOR XML PATH(''),TYPE
        ).value('.','NVarchar(max)'),1,2,''),
    @ln =
STUFF((
            SELECT '+ ' +ln as 'data()' FROM
                    SELECT CASE WHEN collation_name is null THEN CAST(max_length as Varchar(10)) ELSE 'LEN('+name+')'END as ln FROM sys.columns where object_id = object_id(@table)
                ) a
            FOR XML PATH(''),TYPE
        ).value('.','NVarchar(max)'),1,2,'')
PRINT @ln
SET @sql = 'SELECT '+@clmns+','+@ln+' as ln FROM '+@table+' r'
EXEC (@sql)
