LOGUSER VARCHAR2(20)
I created one form "user_activity" with two buttons named "IN" and "OUT"..
when i press "IN" button i want to store follwing in LOG table..
LOGUSER----> This should store the global variable value derived from another form called "login_main"...Actually i called "user_activity" form from "login_main" with global variable..this global variable have the username who is currently logged in...But my problem is i cant insert this value..
NOTE: pls tell me how can i check this global variable is hold value or not...
IN_HR---> This is successfully updated in log table..
in_min--> This is successfully updated in log table..
Pls help me how to store this global variable value into log table... my actual code is follows..I write this code in "when-button-pressed"trigger of "IN" Button..
<code>
declare
     name varchar2(30);
begin
     name:=:global.username;
     insert into log(loguser)values(name);
commit;
:CUSTOMER.IN_TIME:=to_char(sysdate,'hh24:mi:ss');
update log set in_hr=round(to_number(to_char(sysdate,'HH24'))),
in_min=round(to_number(to_char(sysdate,'mi')))
where loguser=name;
commit;

Hello,
please don't open multiple threads for the same question. It only adds confusion to those willing to help you, and you won't get quicker answers when posting questions more then once.
Also, mostly solutions to problems are version dependend, so the very first thing you should do is to provide the involved versions (database, forms, java, OS; remember that oracle products have 5 digit version numbers; 10g is not a version number, 10.2.0.5 is; also "Windows" has a lot of flavors; "Windows 3.11" is also "Windows", so don't say just "Windows"). Even if you think a solution isn't version dependend provide the involved versions. It isn't much effort on your side and saves us a question roundtrip when it is needed anyway.
after that you didn't give us much to work with except a - sorry but I don't have any other word for this - ill data model where you seem to want to reinvent the date datatype and some code which seem to compile (no I didn't try it). Oh, and the fact that "it didn't work". Did you debug your code? How do you populate your global variable? Did you inspect your global variable before the insert? Also what should be stored in your global? is it the current logged on oracle user? You could simply use user to get this and forget about the global
Oh, and before I forget it:
please, don't reinvent the date datatype, and fix your data model.
loguser varchar2(20)
in_date date
out_date date
insert into log(loguser, in_date) values (user, sysdate);
commit;no muss, no fuss and about 20% of the amount of code you wrote.
cheers
