Show data in a-b format in sql server 2008 -


i using sql server 2008.

i have table has distinct numbers i.e int data type. need query shows data in increasing order in format cast(a varchar)+'-'cast(b varchar) i.e a-b a smallest number has yet not been shown , b subsequently next smallest number.

i know sql server 2012 has lead function make question moot how do on sql server 2008?

create table #nr(nr int); insert #nr(nr)values(9),(7),(1),(2),(25),(33),(10),(3);  select     cast(n_o.nr varchar)+'-'+cast((select min(n_i.nr) #nr n_i n_i.nr>n_o.nr) varchar)     #nr n_o     (select min(n_i.nr) #nr n_i n_i.nr>n_o.nr) not null order     nr;  drop table #nr;

results in:

╔══════════════════╗ ║ (no column name) ║ ╠══════════════════╣ ║ 1-2              ║ ║ 2-3              ║ ║ 3-7              ║ ║ 7-9              ║ ║ 9-10             ║ ║ 10-25            ║ ║ 25-33            ║ ╚══════════════════╝
