Oracle 10g Insert query performs inconsistent as a query vs procedure and p

Question

Database Version: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
No error messages....
I am facing a very weird issue that I have a insert statement in a procedure... pretty much
inert
into oracle_Table
SELECT cr.a AS a,
cr.b AS b,
cr.c AS c,
max(d.column_name) as d
FROM "table 1"@Pmo.World Cr,
[email protected] d
WHERE d."a" = cr."column name"
GROUP BY cr.a,
cr.b,
cr.c
@Pmo.World is a database link to a MSSQL...
The problem I am having right now is, every time I run this insert as a query. Everything works as what it should be... However, when I put this insert into a procedure, it inserts nothing...
Simple test Proceudre:
declare
-- Local variables here
i integer;
begin
inert
into oracle_Table
SELECT cr.a AS a,
cr.b AS b,
cr.c AS c,
max(d.column_name) as d
FROM "table 1"@Pmo.World Cr,
[email protected] d
WHERE d."a" = cr."column name"
GROUP BY cr.a,
cr.b,
cr.c
end;
Thinking about character conversion issue I changed the procedure to
inert
into oracle_Table
SELECT to_char(cr.a) AS a,
to_char(cr.b) AS b,
to_char(cr.c) AS c,
max(d.column_name) as d
FROM "table 1"@Pmo.World Cr,
[email protected] d
WHERE d."a" = cr."column name"
GROUP BY cr.a,
cr.b,
cr.c
Then this Inser works in the procedure... however when I revert it back with the original version that doesnt have to_char... it is working still... then I kept it running for few days... since it runs once per day, it was working for the first 2 days and then stopped working the third day... I verified the source table and every time this procedure runs, source tables were not empty...
It is so confusing because if I manually run the insert as a query, it worked every time I ran it... however if I put that into a procedure, it works from time to time..
Any help is highly apprecaited

Thanks for the hints up... I have updated my post... As I post the test procedure...it is about the exact the same as the insert query... Every time, the insert would actually insert data into the table but every time I run the test procedure, nothing gets inserted in... It sounds unbelievable but it happens... ThanksYou obviously haven't read the FAQ, or at least you haven't bothered doing what it asks. Help us to help you.
Can you recreate the problem with simpler data on your local machine? If so provide create table and insert statements for test data.
Format your code and place between tags.
At the very least post the *exact* SQL or PL/SQL you are trying to run: what you've posted isn't even valid SQL.
