sql server - SQL - how to order fields with values like 1.4.2 -


how write sql order text field called "sequentialorder" values 7.5.5 records come out in order of 

    1.2.4     2.3.8     11.3.4

and not this

    11.3.4              1.2.4     2.3.8

you have parse given version strings access components implement order by semantics. there many ways it. try avoid clr code, here comes suggestion: parse version using dot separator, convert each value number, aggregate columns , use proper order byclause:

-- script uses function [dbo].[delimitedsplit8k] split delimited -- string value multiple rows; published , avalable @ -- http://www.sqlservercentral.com/articles/tally+table/72993/  -- setup create table version (id varchar(20)) insert version (id) values('1.2.4'); insert version (id) values('2.3.8'); insert version (id) values('11.3.4');  -- cte query ; inrows (   -- split version id many rows   select ver.id, dlm.itemnumber, convert(int, dlm.item) item   version ver   cross apply [dbo].[delimitedsplit8k](ver.id, '.') dlm ) , incols (   -- aggregate rows groupped id   select inr.id   , max(case when inr.itemnumber = 1 inr.item else null end) [major]   , max(case when inr.itemnumber = 2 inr.item else null end) [minor]   , max(case when inr.itemnumber = 3 inr.item else null end) [revision]   inrows inr   group inr.id ) select * incols inc order inc.major, inc.minor, inc.revision;  -- results ================================================ -- id                   major       minor       revision -- -------------------- ----------- ----------- ----------- -- 1.2.4                1           2           4 -- 2.3.8                2           3           8 -- 11.3.4               11          3           4

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
