Default values on insert

This has probably been asked and answered, but I couldn't find the answer
when searching the newsgroups. On most of my database tables, there is a
date column to store the date when a row was added (it is never changed
after insert). Without Kodo JDO, we would just set the default value for
the column in the database. What is the easiest solution for this with
Kodo?

Is the only way to do what I want is to use InstanceCallbacks?Yeah, I would recommend using jdoPreStore() to set it to the current
date.
The other option is to have a trigger in the database itself override
the value of the "date_created" field to the current time upon insert.

I Cant insert all values to the table But only Default Values r inserted?

Hai,
i can insert only default values to the database. Other values are not shown in DB.
Steps I have done so far:
I have created EO based on VO and VO has the query : select * from emp. Attached to AM.
That AM is attached to the Page. The page consists of employeed details and SAVE button.
Set controller for that page and CO-PR calls create method in AM .
Default values for who columns and SLNo also set through sequence.
In CO-PFR I call apply method which commits the data.
when i run the page and giving values it is not inserted into table but only default values are inserted.
I checked with System.out.println(getattribute("my attr").toString()). It send output correctly.
But y other values are not inserted.?
Anybody plz plz help me in this regard. I am struggling with this for last 1 week. I have to apply this to another realtime scenorio? Deadline is near.
Regards,
Lakshmi Chandiran

Hai Prince,
Thanks for your immediate response. pls find my codes written in EO,AM,CO.
In VO i havent added anythig xcept the query.
The following fields are only getting inserted in the table.
My EOImpl code:
public void create(AttributeList attributeList) {
super.create(attributeList);
System.out.println("NOW I AM IN CREATE METHOD");
OADBTransaction transaction = getOADBTransaction();
Number EMP_ID = transaction.getSequenceValue("Employeeid");
setEmpId(EMP_ID);
setCreationDate(transaction.getCurrentDBDate());
setStartDate(transaction.getCurrentDBDate());
setLastUpdateDate(transaction.getCurrentDBDate());
setCreationDate(transaction.getCurrentDBDate());
VO:
select * from emp1
AM:
public void saveForm()
OAViewObjectImpl empvo = getEMP_VO();
System.out.println("NOW I AM IN AM SAVEFORM OF EMTS");
if ( !empvo.isPreparedForExecution())
empvo .executeQuery();
Row prow = empvo .createRow();
empvo .insertRow(prow);
prow.setNewRowState(Row.STATUS_INITIALIZED) ;
System.out.println("NOW I AM IN ROW CREATED");
public void commitdata()
System.out.println("commitMethod()") ;
getDBTransaction().commit();
CO:PR & PFR:
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
if(!pageContext.isFormSubmission())
pageContext.getApplicationModule(webBean).invokeMethod("saveForm",null);
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule EMP_AM = pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)EMP_AM.findViewObject("EMP_VO");
if ( pageContext.getParameter("BtnSave") != null )
pageContext.getApplicationModule(webBean).invokeMethod("commitdata");
s1 = (String)vo.first().getAttribute("Empname");
s12 = (String)vo.first().getAttribute("Emptype");
s3 = (String)vo.first().getAttribute("Emporg");
s4 = (String)vo.first().getAttribute("Empcity");
System.out.println(" values are " + s1+s2+s3+s4);
here i can get the values correctly printed in output as entered in the form.
I dont know where the problem is.

Using default values in INSERT INTO..SELECT..

Hi,
I like to do following insert in Oracle 10g
INSERT
INTO tab1
x1,
x2
SELECT
NVL(y1,DEFAULT),
y2
FROM tab2
but oracle throws missing expression error. I don't want to substitute default values as it involves code change for any default value change. I suppose Oracle changes context to tab2 while SELECT, but is there any way to accomplishing the above INSERT?
Edited by: ponn_raj on Jan 14, 2009 4:52 AM

Hi,
Welcome to the forum!
DECLARE
var number;
BEGIN
    INSERT INTO test
        (col1,
         col2)
    VALUES
        (1,
         NVL(var, 0));
    COMMIT;
END;
/Also you can create the table and assign default values to the columns that you want. See [CREATE TABLE|http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7002.htm#i2095331].
From the link above:
DEFAULT
The DEFAULT clause lets you specify a value to be assigned to the column if a subsequent INSERT statement omits a value for the column. The datatype of the expression must match the datatype of the column. The column must also be long enough to hold this expression.
The DEFAULT expression can include any SQL function as long as the function does not return a literal argument, a column reference, or a nested function invocation.

Default values for Insert and Update

What is the best way to default the current sysdate for a date column on a table when doing an insert or update through a form? And related to this, what is the best way to default the current user (APP_USER) for a varchar2 column when doing an insert or update through a form?
For these columns, I want to display them on a report, but they should be hidden on the form because I would like to have the app default the values to sysdate and APP_USER. However, when I have tried to use the table default values in "user interface defaults" and using either :APP_USER or &APP_USER or SYSDATE, it only shows this literal value on the form (item is not hidden while I debug this). It does not show the actual value I'd want, such as "user1". Does this make sense?
Thanks for your help.

I think triggers are the best device.

How to insert a default value into MS server in java - help please

hi
suppose if i have a table and one of the column has a default value when the table was created. how can i insert the default value into this column? assuming that the column is the second column and i can't specify the column name when inserting. thanks.

thanks for ur response, so if i have insert statement as follow
insert into someTable values (1,'val1', 'val2', 'val3', 'val4')
and column 3 has default value = DEFAULT
then, to insert default value, my insert statement will look like this
insert into someTable values (1,'val1', 'val3', 'val4')
but the number of values will not match the number of columns.

Best way to put the default values for the Form Items

Hi,
I am having a form with lot of default values as mentioned below..
Field                      value

item1                     value1
item2                     value2Currently I am using Computation -> After Submit.....so whenever we create/update a record...these computaion takes place and the default values get inserted....THIS IS WORKING PERFECTLY FINE.
I want to know..if this approach is fine OR we may have some better approach to acheive this...????

Msql and o8i - using a default value in an insert

1. In an Oracle 8i Enterprise DB I have a primary key in table FOO called FOO_ID, it's SQL description is:
FOO_ID NUMBER DEFAULT TO_CHAR(sysdate, 'HH24MMSSMMDDYY') NOT NULL
1.5 I test via TOAD inserting a record into the DB without specifying FOO_ID, but specifying other values in the table row. I commit the data. When I commit the table correctly fills in FOO_ID with a time/date stamp per the above definition.
2. I run wtgpack and create an application which uses this table. I check the SQL code to make sure the column definition is copied to the snapshot which will be the basis for Oracle 9i Lite mobile DB on my laptop.
3. I run msync.exe and get the DB.
4. I run msql to make sure the data replicated ok. It did.
5. I run an INSERT statement not specifying a primary key hoping that the default will be used. For example,
"INSERT INTO FOO (FOO_TYPE) VALUES ('Test Type')";
I get the following error from msql:
[POL-3221] null key in primary index
The questions is, why isn't the O9iLite DB using the default value when creating the new record/row?
Thanks,
Z

Danny is spot on, but a little elaboration for the beginner:
childValue == "yes" asks whether these two are the exact same String object. There are times when that's true, but it's unlikely. Instead, use String equals() ( childValue.equals("yes") ) to ask whether the two have the same value.
With the simple class Danny suggests:
class Vessel {
   private boolean assessed;
   private int stenosis;
   public boolean isAssessed() { return assessed; }
}All you need in the loop is
Iterator vessels = vesselAssessed.values().iterator();
while (vessels.hasNext()) {
   Vessel vessel = (Vessel) vessels.next();
   if (vessel.isAssessed()) {
}

How to insert into default values in onli 1 column of a table

if u create a table with onli 1 column
which can accept a default value of say
only 100.
then how do u actualli enter values into the table.
is there any data dictionary which stores details about default
values of a table

The default value for a column is the value that will be stored
for that column if you do not provide one in your insert
statement. If you do provide a value, then it will be stored in
the column.
You can query user_tab_columns ( or all_ or dba_)to see the
default value assigned to a column.

Putting default values in an insert statement

I am using Oracle 11g.
I have a table called bonus -
create table bonus (
rid int ,
cid int,
bonus int,
vdate date,
amount int
Earler, the bonus table did not have the vdate and amount columns, so I was able to use insertion syntax as follows -
insert into bonus (cid,rid,bonus) <--- note this
select cid, rid, count(*)
from checkin
group by cid,rid having
count(*) > 2;
However, since I now have two additional fields, I do not know how to do it. I tried something like
insert into bonus (cid,rid,bonus, sysdate, 20) <--- note the change
select cid, rid, count(*)
from checkin
group by cid,rid having
count(*) > 2;
but it failed. So you see that I would like to enter sysdate and 20 as default values into the vdate and amount fields. I am just not able to figure out a way to do it. Please help.
Thank you.

You can insert default values like this,
INSERT INTO bonus (cid
                  ,rid
                  ,bonus
                  ,vdate
                  ,amount)
     SELECT cid, rid, COUNT (*), SYSDATE, 20
       FROM checkin
   GROUP BY cid, rid
     HAVING COUNT (*) > 2;g.

SQL Loader- Default value is not inserted in table by direct method

Hi All,
I am trying to load data from a file to a table by SQL Loader. There is a particular date column which I am not loading from the File but have used a Default constraint to put SYSDATE in it. When I am using direct method load then it is not inserting nothin in this column but in conventional method it is inserting SYSDATE. But I want to do the load by direct method. Can anybody provide me a solution as how to load default value in direct method?
Thanks & regards.
Sudipta

For this special case, you can specify:
column_name SYSDATE
in your SQL*Loader control file.

How to insert row where DB date field has default value.

APEX 4.1, Oracle 11.2
I'm trying to insert a row using "javascript:addRow();" where the report query is an SQL Query (Updateable Report).
1) Several of the fields are display-only with defaulted values.
2) No problem with the VARCHAR2 fields.
3) And if RUN_DT is a text field, the insert works.
4) But I get errors when trying to make RUN_DT (DD-MON-YYYY) display-only and default it to P63_RUN_DT. I display P63_RUN_DT so I see it is correct.
Now, this is not a new question. See:

Various folks recommended using Default PL/SQL and SYSDATE when SYSDATE was the desired default value. That worked for some and not for others. I could not get it to work for me. The errors I receive are "•Column must have a value. (Row 1) " and "ORA-01410: invalid ROWID". I believe the ROWID error is an example of spurious error cascade caused by the RUN_DT problem. I believe it will disappear once the RUN_DT problem is solved.
I will try to replicate on apex.oracle.com
Thoughts?
Howard

Update: At least in my case, it seems the RUN_DT date column cannot be Standard Report Column. I made it "Display as Text (saves state)". Standard Report Column works for the defaulted VARCHAR2 columns. Go figure!
(more) And I could not get it to work with "Item" (P63_RUN_DT) as the Default. However, it seems to work -- so far -- using Default PL/SQL of TO_DATE(:P63_RUN_DT,'DD-MON-YYYY').

Gouri,
You can just simply edit to each column's report attribute. For example,
To set default date,
Default Type: PL/SQL Expression of Function
Default: sysdate
To set default text,
Default Type: PL/SQL Expression of Function
Default: *'CLERK'*
If you still have an error, what is the error message?

Inserting the default value for non existing date

hello,
i am designing a matrix report for payslip for month wise in oracle 6i report builder.
in that i want to display per day working hours of the month.
i m using following query for achieving my goal :
select a.paycode,b.empname,c.departmentname,to_char(a.dateoffice,'DD') dateoffice,a.shiftattended,round(decode(a.hw,0,a.mannual_hours,a.hw),0) hw,
a.ISMANNUAL,A.STATUS
from tbltimeregister1 a,
     tblemployee b,
      tbldepartment c
where a.paycode=b.paycode and
(a.hw >0 or a.mannual_hours is not null ) and
a.departmentcode='D05' AND
a.departmentcode=c.departmentcode and
a.dateoffice between to_date('01/12/2012','dd/mm/yyyy') and to_date('31/12/2012','dd/mm/yyyy')
ORDER BY A.PAYCODE,A.DATEOFFICEit is displaying the hours for the date in b/w date ranges exist in master table.
my problem is that if any date of a month is not in master data ,it should display the given date in DD format with 0 hours , A(absent) status, and null shift by default.
pl tell me how to modify my query for getting my desirable result.
Thanking You

pl tell me how to modify my query for getting my desirable result.Your problem isn't exactly clear to me. How do you pass the dates to be compared to the DateOffice column? It will be better to ensure the Master table contain data for each date (with some default values) and you will not have to tweak your sql.
Below is a possible solution:
select *
from
select a.paycode,b.empname,c.departmentname,to_char(a.dateoffice,'DD') dateoffice,a.shiftattended,round(decode(a.hw,0,a.mannual_hours,a.hw),0) hw,

select a.paycode,b.empname,c.departmentname,to_char(&date_variable,'DD') dateoffice,null,round(decode(a.hw,0,a.mannual_hours,a.hw),0) hw,

ORDER BY A.PAYCODE,A.DATEOFFICEIf this is not what you are looking for, then
1. Post a script that helps us to create the Tables required in your query
2. Some sample data. That includes the data for master table that has missing dates (4-5 rows should suffice)
3. The expected results from the sample data you posted.
