Hello

I run this code and get this error

What it says. SAS technical support needs to handle this.

Unless there‘s a many-to-many relationship with regards to the keys, consider doing this in a DATA step.

Re: Error

Ksharp — Mon, 01 Sep 2025 08:27:00 GMT

There must be an error hidden in your code.

According to your LOG:

NOTE: Invalid (or missing) arguments to the ROUND function have caused the function to return a missing value.

I guess you should change this

round(a.Mirvach_From_prime,0.01)-round(b.PrimeSpread,0.01)=0

into

round(a.Mirvach_From_prime,0.01) = round(b.PrimeSpread,0.01)

Because yours is unbalance expression that would lead to an error in general.

LinusH — Mon, 01 Sep 2025 15:22:43 GMT

My experience of sending this type of errors to SAS support isn't great, they can rarely point out what causes the error. So I have usually solved it by restructuring the query.
How large are the tables? (in saswork by looking into you program)

Re: Error

Ronein — Mon, 01 Sep 2025 19:20:39 GMT

You are right!! I just don't understand what do you mean unbalanced? Why is it bad code? The part you mentioned

Re: Error

Ronein — Mon, 01 Sep 2025 19:21:23 GMT

It is many to many

Re: Error

Ksharp — Tue, 02 Sep 2025 07:06:20 GMT

I will give you an example:

1    proc sql;
2    select *
3     from sashelp.class as a,sashelp.class as b
4      where round(a.weight,0.01)-round(b.weight,0.01)=0;
NOTE: Writing HTML Body file: sashtml.htm

NOTE: PROCEDURE SQL used (Total process time):
      real time           0.83 seconds
      cpu time            0.35 seconds

If using your code, you would get nothing.

6    proc sql;
7    select *
8     from sashelp.class as a,sashelp.class as b
9      where round(a.weight,0.01)=round(b.weight,0.01);
10   quit;
NOTE: PROCEDURE SQL used (Total process time):
      real time           0.03 seconds
      cpu time            0.01 seconds

If using my code , you would get 17 obs.

Thank you, @Ksharp, for pointing this out.

Now I am puzzled. Is this a known bug in PROC SQL? Is it limited to the ROUND function? I haven't found a related problem note (such as https://support.sas.com/kb/69/271.html).

Here's a boiled down example using two very simple, identical datasets A and B:

data a b;
input x;
cards;
1
2
;

proc sql;
create table c1 as
select . 
from a, b
where round(a.x)-round(b.x)=0;
create table c2 as
select . 
from a, b
where round(a.x,1)-round(b.x,1)=0;
create table c3 as
select a.* 
from a, b
where round(a.x,1)=round(b.x,1);
create table c4 as
select a.* 
from a, b
where round(a.x,1)-round(b.x,1)=0;
quit;

Log of the PROC SQL step from Windows SAS 9.4M5:

8     proc sql;
9     create table c1 as
10    select .
11    from a, b
12    where round(a.x)-round(b.x)=0;
NOTE: Table WORK.C1 created, with 2 rows and 1 columns.

13    create table c2 as
14    select .
15    from a, b
16    where round(a.x,1)-round(b.x,1)=0;
NOTE: Table WORK.C2 created, with 0 rows and 1 columns.

17    create table c3 as
18    select a.*
19    from a, b
20    where round(a.x,1)=round(b.x,1);
NOTE: Table WORK.C3 created, with 2 rows and 1 columns.

21    create table c4 as
22    select a.*
23    from a, b
24    where round(a.x,1)-round(b.x,1)=0;

Specifying 1 as the rounding unit in the second argument of the ROUND function should be redundant. However, in the WHERE condition of the form "difference = 0" it produces an incorrect result in table C2 (0 rows instead of 2) and a Read Access Violation error while creating table C4.

Freelance,
Sorry , I have no idea about this either.
The only ERROR looks like in OP code is that unbalanced expression, so I suggested OP to fixed it by my code.
