Обсуждение: Group By Error Text

Hi

with the following query:

select jobno, count(jobno) from drawing_register;

I get the following error:

ERROR:  Attribute drawing_register.jobno must be GROUPed or used in an
aggregate function

Is this correct? Getting rid of the error is easy:

select jobno, count(jobno) from drawing_register group by jobno;

I believe that jobno is being used in an aggregate function. Should a
change be made to the error text?

Regards

Nope.  The error message is exactly correct.   If you didn't want to GROUP BY
jobno, then what you actually wanted to query was:

SELECT count(jobno) FROM drawing_register;
