Restricting data by Date proc sql;

Caroline_22 — Wed, 23 Nov 2016 19:30:36 GMT

Hello,

I am trying to reduce the data returned from a very large table by the date (Proc sql in SAS 9.4)

The format of the column is DDYYMM8. (Number)

In my where clause I have tried:

where date >= 01-01-16

where date >= 01/01/16

and the reverse eg 16/01/01 etc

All attempts so far have resulted in dates still being returned which are older than 01/01/16

Can anyone help please?

try this:

where date LE '01jan2016'd

All of the SAS date stored as numbers, counting days from 1/1/1960. So you either use the number of days directly, in this case, 20454 days from 1/1/1960, or tell SAS how to read it correctly, such as in the above example.
