I cann't commit form when new instance form with form status is "NEW".

And then i call:
Text_Item := WebUtil_File.File_Selection_Dialog('', '', 'Excel 2003|*.xls|Excel 2010|*.xlsx|All File|*.*', 'Select a file to Import', Open_File, True);
Form status change to "QUERY"

And then i click button "Import Data" from excel file to Data Block. Now form status change to "CHANGED". But i cann't call "Commit_Form" built-in to insert data to database oracle 10g

I'm unsure what you are trying to do, and unfortunately your fmb won't open correctly for me.
What do you mean you can't call commit_form?

Thank you for reply.

I want to import data from excel file to oracle database through oracle form. I use WebUtil to browse the path excel file.

In database: i have a table EMPLOYEES with four field: EmpID (varchar2), Emp_Name (nvarchar2), DOB (Date), Sex (char).

CREATE TABLE EMPLOYEES
(
EMPID VARCHAR2(15 CHAR) DEFAULT '' NOT NULL,
EMP_NAME NVARCHAR2(50) DEFAULT '',
DOB DATE DEFAULT '01-Jan-1900',
SEX CHAR(1 CHAR) DEFAULT ''
)

In excel file: there are four column: EmpID | Emp_Name | DOB | SEX
(Sorry, because i cann't attach excel file - Allowed File Extensions: txt sql log lst csv pls plb gif jpg png pdf fmb fmt fmx ora ctl dat bad dsc pks pkb pck rdf)

On form: when i click button "..." to file excel file. After bind the excel path to item text, form status change to "Query". So, i use "Clear_Form" to change form statu to "New" and bind data from excel to the items text on form. Then status form change to "Changed" and data into data block. And then i commit form to save data on data block to oracle database. But i cann't commit. Perhaps i missed a condition....?

Please help me!! Thanks.

Does using standard.commit work?

Why don't you use sqlloader instead? It's whole purpose is load data from files into the DB.

and if u want to copy the value from excel to form block item then add this code before this "copy(cell_value,name_in('system.cursor_item'));"

    if k =1 then
        :A.NO:=cell_value;
    end if;

    if k =2 then
        :B.name:=cell_value;
    end if;

   if k =3 then
        :C.QTY:=cell_value;
   end if;

if still confusing tell me i can send u fmb file

baba
