How to create intervall time per hour or per 2 hour

[Didi_b]

Hello,

I would like to create a new variable T_heure (Hour slice)

These are examples of my trying. I've tried with and without quotations marks. But I keep getting errors.

if 07:30<=NHeure<=08:15 then T_Heure='07:30-08:15';
if 08:30<=NHeure<=09:15 then T_Heure='08:30-09:15';
if 09:30<=NHeure<=10:15 then T_Heure='09:30-10:15';
.
.
.
if NHeure=>16:30 then T_Heure='16:30+';

if Nheure in (07:30,08:15) then T_Heure=1;
else if Nheure in(08:30, 09:15) then T_Heure=2;
else if Nheure in(09:30, 10:15) then T_Heure=3;
else if Nheure in(10:30, 11:15) then T_Heure=4;
.
.
.
else if Nheure in (16:30) then T_Heure=10;

select (Nheure);
 when ("07:30", "07:45", "08:00", "08:15")  T_Heure=0;
  when ("08:30", "08:45", "09:00", "09:15")  T_Heure=1;
  when ("09:30", "09:45", "10:00", "10:15")  T_Heure=2;
 .
 . 
 .
when ("16:30")  T_Heure=9;
  otherwise T_Heure="";
end;

h1=1 if Nheure is (07:30 to 08:15);
h1=2 if Nheure is (08:30 to 09:15);
h1=3 if Nheure is (09:30 to 10:15);
h1=4 if Nheure is (10:30 to 11:15);
h1=5 if Nheure is (11:30 to 12:15);

per hour or per 2hour.

I've tried different ways with if and select fonction but I couldn't make it work. Could someone help me please. I'm really new to SAS and my data tables are too complicated to manipulate.

My variable NHeure is (in SAS time format):

07:30
07:45
08:00
08:15
08:45
09:00

Post the full log and actual code really helps as it highlights where the errors are in the code.

For starters - the time references in SAS are wrong. 

Time values need to be in quotes and end in t, then SAS knows to interpret that value as a time.

if '07:30't<=NHeure<='08:15't then T_Heure='07:30-08:15';
else if '08:30't <=NHeure<= '09:15't then T_Heure='08:30-09:15';
....

That should get you started.

Here's a great, but longer and in depth, reference for dates and times in SAS that is highly worth reading through:

Is NHeure an actual SAS Time variable?

[Didi_b]

Hi yes, First converted to a SAS time Value with this 

NHeure=input(translate(Heure,':','H'),time15.);
format NHeure tod5.;

[CarmineVerrell]

Here is an example i created to help you out .

Data testingT;
/*To reference Dates in code use this format "date"d (followed by a d ) */
/*To reference Times in code use this format "Time"t (followed by a t)*/
/*To reference DateTime in code use this format "DateTime"dt (followed b a dt)*/
endt='08:15't;
starttime="07:15"t;
/*use the intck to compare date values year , month and even hour;*/
hdiff=intck("hour",starttime,endt,"C");
run;

Hi, thank you so much for the tips.

How could accept multiples propositions that work as a solution?

When I accept one, I can't no longer accept other solution  as a solution too.
