sql - ORDER BY separately positive & negative numbers in MySQL statement -

-

i have mysql table , return rows based on column value in order:

  • first ascending order if column >=0
  • then descending order if column <0

e.g. 0,2,4,7,-2,-3,-5

can use sign sort positive numbers top, take absolute value abs desired asc/desc.

select * thetable order sign(col) desc, abs(col)

edit

as nahuel pointed out, above sort 0's middle between positive , negative. instead group them positives, can use case instead (or, if column integers, magical sign(col + 1))

select * thetable order      case when col >= 0 1 else 2 end,     abs(col)

delphi - When I encode/decode SMS PDU (GSM 7 Bit) user data, do I need prepend the UDH first? -

while can encode , decode user data part of sms message when udh not present, i'm having trouble doing when udh is present (in case, concatenated sms). when decode or encode user data, need prepend udh text before doing so? this article provides encoding routine sample compensates udh padding bits (which still don't understand) doesn't give example of data being passed routine don't have clear use case (and not find decoding sample on site): http://mobiletidings.com/2009/07/06/how-to-pack-gsm7-into-septets/ . so far, have been able results if prepend udh user data before decoding it, suspect coincidence. as example (using values https://en.wikipedia.org/wiki/concatenated_sms ): udh := '050003000302'; encoded_user_data_part := 'd06536fb0dbabfe56c32'; // padding, evidently decodeduserdata := decode7bit(udh + encoded_user_data_part); writeln(decodeduserdata); output: "ß@ø¿Æ @hello world" encodeduserdata := encode7bit(decodeduse...
