declare @lastval char(11) 
set @lastval = '17-18/00001' 

declare @i int 
	set @i = right(@lastval,5) + 1 
	--return 'C' + right('000' + convert(varchar(10),@i),4) 
	return '17-18/'+ right('0000' + convert(varchar(11), @i),5) 
select @lastval 'purinvid'
end

--You can try this

--CREATE A TEMPORARY TABLE
CREATE TABLE #myTemp123
(
                Id INT NOT NULL IDENTITY(1,1),
                AutoId AS 'ABC' + RIGHT('0000'+ CONVERT(VARCHAR(5),Id),5)
)
--INSERT DEFAULT 10000 RECORDS AT ONCE IN LOOP Simply TYPE GO 10000
INSERT INTO #myTemp123 DEFAULT VALUES;
--CHECK INSERTED RECORD
SELECT * FROM #myTemp123
