Forms :: 6i - REPORT_OBJECT_STATUS Cannot Be Null

Jan 21, 2010

I have an existing form and report. We recreated our testing environment and now when running any report I first get the following error: REP-3002: Error initializing printer. make sure a printer in installed.

This error pops up when calling RUN_REPORT_OBJECT.

The next line of code checks the report status by using REPORT_OBJECT_STATUS. This check throws out error: FRM-40738: Argument1 to builtin REPORT_OBJECT_STATUS cannot be null.

This indicates that my FIND_REPORT_OBJECT is not returning a value.

All these reports and forms used to work fine on our old testing environment and also works on our live database.

SQL & PL/SQL :: Counting NULL Vs NON-NULL In A GROUP BY Clause

Jun 21, 2010

I am running a GROUP BY query on a few columns of enumerated data like:

select count(*), Condition, Size
group by Condition, Size;

COUNT(*) CONDITION SIZE
-------- ---------- --------
3 MINT L
2 FAIR L
4 FAIR M
1 MINT S

Well, let's say I also have a timestamp field in the database. I cannot run a group by with that involved because the time is recorded to the milisec and is unique for every record. Instead, I want to include this in my group by function based on whether or not it is NULL.

For example:

COUNT(*) CONDITION SIZE SOLDDATE
-------- ---------- -------- ----------
3 MINT L ISNULL
2 FAIR L NOTNULL
2 FAIR M NOTNULL
2 FAIR M ISNULL
1 MINT S ISNULL

Forms :: Search For NULL Fields

Feb 1, 2012

Is there any way to see items in the block having null in them? I want to figure out null field before inserting the data in the database table. At the moment I am having an error ORA 01400 which means that a NULL cannot be inserted into NOT NULL column. So, I want to create a procedure which will fire before insert trigger of the block and it will show me the names of items having null it them.

Procedure check_data(block_name in varchar2)
First_item varchar(20);
Current_item varchar(20);
Last_item varchar(20);
Begin

[Code]..

The problem is that I don't know the function to get the value inserted by user in the field so that I can compare it in IF condition.

Forms :: ROWNUM Returns NULL Rows When Value Greater Than 1

Dec 9, 2011

I am trying to do a simple query where I need to return the rows from a table and treat each rown according to some rules.The query works fine, and returns all the rows, usually I have 2 rows returned. WHen I add to the query where ROWNUM = 1, I get the first row returned, but when I use when ROWNUM =2 OR ROWNUM >1, I always get null rows retured, even if I have rows in the database. Here is my query:

SELECT on_time
INTO on_time2
FROM work.work_unit
WHERE work_code = 1
AND emp_no = :entry_blk.p_emp_no
AND work_date = :entry_blk.p_work_date
WHERE ROWNUM = 2;
--RETURN NULL

I changed it to the following format, but still I get the same results, only I get data when I say when rownum = 1, i get back the first record in the query

SELECT on_time
INTO on_time2
FROM (SELECT on_time
FROM work.work_unit
WHERE work_code = 1
AND emp_no = :entry_blk.p_emp_no
AND work_date = :entry_blk.p_work_date)
WHERE ROWNUM = 2;

I can't move forward in my form until I figure out why this is not returning records

SQL & PL/SQL :: Unique Null And Multiple Non-null

Oct 24, 2013

create table test
(
id int ,
dat date
)
/

I want to implement a business rule such as we have for each id at most 1 dat null. So, I've created this unique index on test.

create unique index x_only_one_dat_cess_null on test(id, case when dat_cess is null then 'NULL' else to_char(dat_cess, 'dd/mm/yyyy') end);

insert into test values (1, sysdate);
insert into test values (1, sysdate - 1);
insert into test values (1, null);
insert into test values (1, null);
-- -----
insert into test values (2, sysdate);
insert into test values (2, sysdate - 1);
insert into test values (2, null);

The 4th insert will cause an error and this is what I wanted to implement. OK. Now the problem is that for non-null values of dat, we can't have data like this

iddat
------------
124/10/2013
123/10/2013
123/10/2013
1

because of the unique index (the 2nd and the 3rd row are equal). So just for learning purposes, how could we allow at most one null value of dat and allow duplicates for non-null values of dat.

SQL & PL/SQL :: Print NULL Entry Along With NOT NULL Entry

May 30, 2010

Suppose that, I have two tables: emp, dept
emp records the empid, emp_name, deptid
dept records the deptid, dept_name

Here is a record, it's a president or some special position in company, so it's deptid is set to NULL. Here comes the question, how can I print all the emp_name with their deptartment name?

I know how to print all the emp_name with their department name if they have dept_id, but is that possible that I merge the record with dept_id NULL?

Forms :: Barcode Label Printing - Prevent Label From Printing N/V For Null Values?

Jul 8, 2013

I have set up a label which interacts with our LIMS system. I have set up variables on this label which pull in attribute values from the available tokens. When the attribute value is null, the label is automatically inserting 'N/V' onto the label.

I would prefer for the variable to appear as a blank field on the label when the attribute value is null in the LIMS. can't find anything in the user's manual. Perhaps there is some setting where you can define what to display for null values. I can't seem to find any information on this.

SQL & PL/SQL :: Trigger With Null Old Value

Feb 15, 2011

I have the following problem.

I have a trigger "before update" that change some values, including a timestamp column. My sql code does an update using the "returning clause" to get the values changed by the trigger. The problem is:

When I do an "update [...] returning timestamp_field", this timestamp_field has the old value equals to null (in the trigger). And, this field in the table is not null. This problem not occurs with the others fields of type number, varchar... only with the timestamp field.

Here are the code to simulate this problem:

--Table
create table TB_TEST
(
ID NUMBER(10) not null,
FLAG NUMBER(10) not null,
TAG VARCHAR2(16) not null,
TS_ATU_DTR TIMESTAMP(9) not null
);

[Code]..

Testing

exec test1;

select * from textolog order by data, texto;

Output:

DATA TEXTO
--------- ----------------------------------------------------------------------------------------------------
15-FEB-11 1:old.FLAG=123, :new.FLAG=321
15-FEB-11 1:old.TAG=teste trigger, :new.TAG=teste trigger
15-FEB-11 1:old.TS_ATU_DTR=, :new.TS_ATU_DTR=
15-FEB-11 2:old.FLAG=123, :new.FLAG=321
15-FEB-11 2:old.TAG=teste trigger, :new.TAG=10
15-FEB-11 2:old.TS_ATU_DTR=, :new.TS_ATU_DTR=15/02/2011 11:07:38.094284000

-----

"old.TS_ATU_DTR=, " Isn't it right?????
Why the other fields aren't null?
I need the "old.TS_ATU_DTR" to use in my other trigger to compare timestamps, how can I get it?

Or, is there a patch for this problem?
