How to update a table

[Ruolin]

Hi all, I am having a problem getting a table in a way I want it to look like.

For example,

my table is the following,

ID_number  SUB_number

ID1                 SUB1

ID1                 SUB2

ID2                 SUB3

I am wondering if there is a query that can transform my table into the following

ID_number     SUB_number       SUB_number2

ID1                   SUB1                    SUB2

ID2                   SUB3

( SUB1 and SUB2 are associated with the same ID1)

Please advise.

data have;

input a $ b $;

cards;

ID1 SUB1

ID1 SUB2

ID2 SUB3

ID3 SUB5

;

run;

proc transpose data=have out=new (drop=_name_);

by a;

var b;

run;

Just a little variation to above creating variable names closer to your output data set

data have;

  input ID_number $ sub_number $;

  cards;

ID1 SUB1

ID1 SUB2

ID2 SUB3

ID3 SUB5

;

run;

proc transpose data=have out=new (drop=_:) prefix=SUB_Number;

  by id_number;

  var sub_number;

run;
