Question: (By David Gray) I'm trying to
catch an ORA-01284 error in a stored procedure. Looking around it
seems as if I have to define my own exception using the PRAGMA
EXCEPTION_INIT key words and then tray the error in a when block.
The problem is I'm getting the following error when compiling:
Error(24,31): PLS-00109: unknown
exception name 'FILE_NOT_AVAILABLE' in PRAGMA EXCEPTION_INIT
The procedure is show below with the new code show in bold.
create or replace
PROCEDURE "MATERIALISE_DATA" (
p_filename varchar2,
p_recordcount OUT number,
p_errorcode OUT number
)
as
begin
declare
cursor c_v_logmnr_contents is
select
logmnr.logmnr_sequence.nextval as IDX,
V.*
from
v$logmnr_contents V
where
seg_owner = 'SONICA' and
operation in ('INSERT','UPDATE','DELETE');
output_rec
c_v_logmnr_contents%ROWTYPE;
v_idx number;
PRAGMA EXCEPTION_INIT(file_not_available,
-1284);
begin
p_recordcount := 0;
p_errorcode := 0;
begin
execute immediate 'truncate table
logmnr.logmnr_contents';
execute immediate 'commit';
end;
dbms_logmnr.add_logfile(LogFileName => p_filename, Options =>
dbms_logmnr.NEW);
dbms_logmnr.start_logmnr(DictFileName
=> 'G:\dtb1\TURLIVE\utl_dir_file\TURLIVE_DICTIONARY.ORA',
Options => dbms_logmnr.committed_data_only);
open c_v_logmnr_contents;
v_idx
:= 0;
loop
fetch c_v_logmnr_contents
into output_rec;
exit when c_v_logmnr_contents%NOTFOUND;
insert into logmnr.logmnr_contents values
output_rec;
v_idx
:= v_idx + 1;
end
loop;
commit;
close
c_v_logmnr_contents;
dbms_logmnr.end_logmnr;
dbms_output.put_line('.
');
dbms_output.put_line('Records fetched in cursor loop = ' || TO_CHAR(v_idx));
dbms_output.put_line('. ');
p_recordcount := v_idx;
rollback;
exception
when
file_not_available
then null;
when others then
p_errorcode := sqlcode;
end;
end;
Answer:
By Steve Callan: You need to declare declare
file_not_available as a
PL/SQL exception:
output_rec c_v_logmnr_contents%ROWTYPE;
v_idx number;
file_not_available
exception; --***********************
PRAGMA EXCEPTION_INIT(file_not_available,
-1284);
