Re: [PL/pgSQL] How should I use FOUND special variable.

Hi!

Just use this:

FETCH crs_cnt into row_cnt;
EXIT WHEN NOT FOUND;

Greetings,

Subject: [GENERAL] [PL/pgSQL] How should I use FOUND special variable.
Documentation is little unclear for me

Hello.

I'm porting some procedures from PL/SQL and I encountered following
problem:
In PL/SQL I'm using this statement related to cursor:

OPEN crs_cnt(start_millis, end_millis);
LOOP
FETCH crs_cnt into row_cnt;
EXIT WHEN crs_cnt%NOTFOUND;
insert into spm_audit_stats values(SEQ_SPM_ID_AUTO_INC.nextval,
start_millis, base_stat_period, row_cnt.adt_count, row_cnt.adt_avg,
row_cnt.adt_max, row_cnt.adt_min, row_cnt.adt_stdev,
row_cnt.adt_service_name, row_cnt.adt_root_user);
global_counter := global_counter + 1;
END LOOP;
CLOSE crs_cnt;

Now, I need to do the same action in PL/pgSQL. It's rather simple, but I
don't know how to use FOUND variable described in documentation:

FETCH retrieves the next row from the cursor into a target, which may be a
row variable, a record variable, or a comma-separated list of simple
variables, just like SELECT INTO. As with SELECT INTO, the special variable
FOUND may be checked to see whether a row was obtained or not.

When I'm trying to use it in Oracle way, my DB reports error. Also I tried
to use it like that:

IF NOT crs_cnt%FOUND THEN ...

But it also doesn't worked for me.

Thanks for any help.

Kind Regards.
