Hi,
I am having a function like this
create or replace function audio_format_func (
in p_bitrate audio_format.audio_bitrate%TYPE,
in p_sampling_rate audio_format.sampling_rate%type,
in p_bit_per_sample audio_format.bit_per_sample%type,
in p_audio_codec audio_format.audio_codec%type,
in p_mimetype audio_format.mimetype%type,
in p_mono_stero audio_format.number_of_channel%type) returns int as
$$
DECLARE
p_audio_id audio_format.audio_id%type;
begin
select audio_id into a
from audio_format
where audio_bitrate = p_bitrate
and sampling_rate = p_sampling_rate
and mimetype = p_mimetype
and number_of_channel = p_mono_stero
and audio_code = p_audio_codec;
return 1;
exception
when NO_DATA_FOUND
then
return 100;
end;
$$
language 'plpgsql';
When I compile, I am getting an error message
ERROR: unrecognized exception condition "no_data_found"
CONTEXT: compile of PL/pgSQL function "audio_format_func" near line 15
How will I handle exceptions in postgres?
Please advise.
