Error from proc sql

[CathyVI]

Hi,

I am getting an error and warning from a proc sql that seems to be rightly coded. Here is the code and my log. Any help is highly appreciated.

1. WARNING

proc sql;
create table prostate AS 
select distinct PATIENT_ID
from ao.T01_P01_PROSTATE;
quit;

Here SAS is saying that the use of AS is misspelled. This is the warning in the log

167 proc sql;
168 create table prostate AS 
___
1
WARNING 1-322: Assuming the symbol AS was misspelled as AS .

169 select distinct PATIENT_ID
170 from ao.T01_P01_PROSTATE;
NOTE: SAS threaded sort was used.

2. ERROR

proc sql;
create table prostate2 AS 
select distinct prostate.PATIENT_ID, bio.lookup_dt, mri, bio.DT_DIAG_PRC, max(mri.lookup_dt) as mri_lookup_dt /*format=mmddyy10.*/

left join bio on prostate.PATIENT_ID = bio.PATIENT_ID
where mri.lookup_dt <= bio.lookup_dt
group by prostate.PATIENT_ID, mri.PATIENT_ID, bio.PATIENT_ID;

quit;

@CathyVI please from now on, paste the log files into the window that appears when you click on the </> icon, as I have done. This improves the formatting and readability of the log. Do this every single time from now on. Every single time.

The problem that SAS is indicating is most likely cause by an unprintable character appearing immediately before or after AS. How can that happen? Usually if the code has been copied from some other software or file format which is not a true text editor, such as MS Word, MS PowerPoint, MS Excel or even PDF files. The solution is to erase prostate AS and then re-type it manually.

@PaigeMiller Thank you. I will always remember to put the code in the insert code.
