Unable to delete records.

kumarsandip975 — Mon, 22 May 2023 19:56:42 GMT

I have amount columns as below, few amount column is 0(Zero) values, and some are more than Zero. I do not want Zero values from amount column. proc contents as below.

#	Variable	Type	Len	Format	Informat	Label
5	amount	Num	8	18.

When I am using as below, still I see amount 0 is there in output and not deleting. May I know what I am missing here in condition.

data want;

set have;

if amount=o then delete;

run;

Your example code does not have a zero in it. Instead it has a lowercase letter O.

Try using zero instead.

data want;
  set have;
  if amount=0 then delete;
run;

If that still show some values as zero then perhaps they are between -0.5 and 0.5 since you asked SAS to display the values as integers by attaching the display format of 18. to the variable.

Try using the ROUND() function to round the value to an integer before comparing it to zero.

data want;
  set have;
  if round(amount,1)=0 then delete;
run;

Or perhaps you should display the values with a different format so you can see if they have something other then zero there that you might want to keep?

proc freq data=have;
  tables amount ;
  format amount best18.;
run;

If this:

data want;
set have;
if amount=o then delete;
run;

is really your code, then the log will most probably tell you that variable o is uninitialized, unless o is also contained in dataset have.

o was typo, I mean if amount=0 then delete;
