Dear Friends,
I have Created Master Detail form and and running fine but some times it throws error wrong argument supplied while saving the form and when i clear the form and reenter the same data it again shows the same error but when we exit the form and repoen the form and reenter the same data it is saved.
When i am viewing the error by pressing ctrl+shift+e it shows the incorrect insert statement like
insert into table )values ) ...............
above is the form generated statemnt.
I have Tried a lot but could not resolve this problem.
Please suggest some remedy.

yes this is the same as display_error
which throws error as
wrong argument supplied
and statement is
Insert into t_visitor( value ( ...........
red color bracket is very much confusing.......
I have tried a lot to resolve this but could not
and this error comes in a very inconsistent way, any time, and when it comes, i have to exit the form and reload the form, after reloading the form, the same data is accepted, in which error was thrown.
one more thing i want to add that there is one blob column in my table but it is always empty in my case.
exact ora error code no i will communicate when i face this error next

Actually I created form using data block wizard after that i have created when validate record trigger in master block and in which i have inserted insert statement which inserts data to some other table which is none related to my master or detail block table.
and the master block table is having foriegn key referring to the table where i am inserting the records manually in the when validate record of the master block.

In my opinion, WHEN-VALIDATE-RECORD (WVR) is not the best choice to do that.
Suppose that user enters that record, moves to another record; WVR trigger fires and performs INSERT INTO statement you wrote. Then user navigates back to the previous record, modifies some items, navigates out of that record. WVR trigger fires again and performs another INSERT INTO. Is that OK?
Maybe you should consider moving INSERT INTO into a PRE-INSERT trigger, or even into the database trigger.
However, none of above explains why you occasionally get wrong argument supplied error ... Do you, by any chance, use some kind of dynamic SQL? Could you post contents of the WHEN-VALIDATE-RECORD trigger?

ok i will provide you the wvr trigger on 30-07-14 when i will join my office .
whereas your concern about dupicating of insert statement is not possible in my trigger because i have taken care for this using IF - ENDIF statement, still i will apply my insert statement in pre-insert trigger as suggested by you and let us see.
moreover problem comes(whenever it comes ) in detail block only, when we save data of master block only (leaving detail block blank)form never generates error, and wvr is wriiten on Master block, so i think chances of malfunctioning at master block level is very less.
I haven't used any dymanic sql type of things.
regards.

 Snap shot for the error is attached.
Following is the code form WVR
p_chk_company;
if :system.record_status in ('CHANGED') and
:m_visitor.m_vtr_time_out_lab is not null and
:m_visitor.m_vtr_time_out_gate is not null then
:m_visitor.m_vtr_exit_by := lower(get_application_property(SSO_USERID));
end if;
p_chk_company is the procedure code for this as follows:
PROCEDURE p_chk_company IS
alert_id alert := find_alert('MESSAGE_ALERT');
alert_btn number;
v_code number ;
v_count number ;
begin
select count(*) into v_count from m_company
where
m_cmp_name = :m_visitor.company_name and
m_cmp_addr1 = :m_visitor.add_1 and
m_cmp_addr2 = :m_visitor.add_2 and
m_cmp_city = :m_visitor.city and
m_cmp_pincode = nvl(:m_visitor.pin,0);
if v_count = 0 then
select seq_comp_code.nextval into v_code from dual;
insert into m_company values(v_code,:m_visitor.company_name,:m_visitor.add_1,:m_visitor.add_2,:m_visitor.city,nvl(:m_visitor.pin,0));
end if;
select max(m_cmp_code) into :m_visitor.m_vtr_cmp_code
from m_company
where
m_cmp_name = :m_visitor.company_name and
m_cmp_addr1 = :m_visitor.add_1 and
m_cmp_addr2 = :m_visitor.add_2 and
m_cmp_city = :m_visitor.city and
m_cmp_pincode = nvl(:m_visitor.pin,0);
exception
when OTHERS then
set_alert_property(alert_id, ALERT_MESSAGE_TEXT, 'P_CHK_COMPANY: '||error_code||' ~~ '||error_text||' DBMS: '||dbms_error_code||' ~~ '||dbms_error_text);
alert_btn := show_alert(alert_id);
END;

As you said, you didn't create INSERT INTO so it must be Forms itself. If it created such an invalid INSERT statement, maybe you hit a bug. Did you search My Oracle Support? I don't have any other ideas, sorry.
