DECLARE @date vARCHAR(10) = '20130913' --YYYYMMDD
SELECT DATENAME(year,@date) + '-' + DATENAME(quarter,@date) AS [YYYY-quater],
DATENAME(year,@date) + '-' + RIGHT('00' + CAST(DATEPART(month,@date) AS varchar(2)),2) + '-' + DATENAME(ISO_week,@date) AS [YYYY-MM-Week]

its obvious that you're using MySQL. This is MS SQL Server forum. You may be better off trying this in some MySQL forums to get specific syntax help

return 'R' + right('0000' + convert(varchar(10),@id), 4)

should be

return concat('R' , right(concat('0000' , @id), 4))
