Understanding NVL: INVALID NUMBER in NVL Function

Hi,
The below query is a part of a cursor which takes in p_po_number as input with datatype same as segment1 of po_headers_all (varchar2(20)). The columns event_system_id1 to event_system_id4 are varchar2(240). In most cases p_po_number will be null as the program is scheduled and the input parameter of p_po_number is not passed. In effect, for most cases, the below query will end like event_system_id1 = NVL(NULL,event_system_id1)
I am getting an error of INVALID NUMBER
SELECT TO_NUMBER (event_system_id1)
FROM c_fnd_intf_transact_q
WHERE event_system_id2 = :p_organization_code
AND event_system_id4 =
DECODE (:p_po_type,
:vgc_internal, 'XXX',
:vgc_standard
AND event_system_id1 =
NVL (p_po_number, event_system_id1)
I modified the query to
SELECT event_system_id1
FROM c_fnd_intf_transact_q
WHERE event_system_id2 = :p_organization_code
AND event_system_id4 =
DECODE (:p_po_type,
:vgc_internal, 'XXX',
:vgc_standard
AND event_system_id1 =
NVL (p_po_number, event_system_id1)
which still threw the same error thus ruling out the cause of the issue being that to_number leaving only the implicit conversions of NVL.
I further modified the query to
SELECT TO_NUMBER (event_system_id1)
FROM c_fnd_intf_transact_q
WHERE event_system_id2 = :p_organization_code
AND event_system_id4 =
DECODE (:p_po_type,
:vgc_internal, 'XXX',
:vgc_standard
AND p_po_number is not null
which gave me the desired result in a round about way.
What confuses me here is both p_po_number and event_system_id1 are of varchar2 type. Why am I getting the error of INVALID NUMBER here and why is NVL converting the second parameter NUMBER datatype when the first one is VARCHAR2 even though null.
I am working in Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production.
P.S: The column event_system_id1 is not restricted to store numbers alone. It also contains character values though I use it only for storing number as it is shared table.

Well, the expression
NVL (p_po_number, event_system_id1)
has NUMBER and VARCHAR2 elements, and you say "+P.S: The column event_system_id1 is not restricted to store numbers alone+" , and the documentation:
http://download.oracle.com/docs/cd/E14072_01/server.112/e10592/functions117.htm
says:
+The arguments expr1 and expr2 can have any data type. If their data types are different, then Oracle Database implicitly converts one to the other. If they are cannot be converted implicitly, the database returns an error. The implicit conversion is implemented as follows:+
+•If expr1 is character data, then Oracle Database converts expr2 to the data type of expr1 before comparing them and returns VARCHAR2 in the character set of expr1.+
+•If expr1 is numeric, then Oracle determines which argument has the highest numeric precedence, implicitly converts the other argument to that data type, and returns that data type.+
Exactly what is it you don't understand?

Pipelined function with Union clause(Invalid Number(ORA-01722) error )

Hi,
I have a pipelined function.
I am fetching the data with the use of a REF cursor.
The query has two part: query1 and query2
when I am opeing the cursor with query1 UNION query2,it is giving me Invalid Number(ORA-01722) error.
but when I open the cursor separately for query1 and query2,I am getting the resultset for each of the query.
query1 and query2 are running fine with UNION in the sql editor.
But,when I put them into two variables (var1 :='query1' and var2:='query2' and try to open the cursor with var1 UNION var2 , it's giving me the error.
But when I put query2 as 'Select ..... from dual' and then try to open the cursor for query1 UNION query2,
then getting the result of query1 and one extra row for query2(dual).
The FROM table set is same for query1 and query2..
can anyone please help me , why this Invalid Number(ORA-01722) error is coming.

NVL function's strange behaviour

Hi,
I have a sql statement (listed below) that uses NVL function which returns either the business name of branch name depending on whether the business name is null or not. It also uses the branch_name pl/sql function that returns the name of the branch.
What I found strange was that it executes the branch_name function even when the business_name is not null. It was my understanding that nvl returns expr1 if it's not null, and expr2 if expr1 is null. I don't want it to execute the branch_name function if business_name exists. Is it possible using NVL, or do I need to use DECODE to achieve that? p_record_id is a parameter that I pass to the function containing the sql statement e.g., p_record_id=10.
SELECT nvl( business_name, branch_name( p_record_id) ) "Name"
FROM entity
WHERE record_id = p_record_id;
Thanks
Vic

Marc,
Thanks for looking into it.
I just ran the code using DECODE and it seems that it executes the function only when the condition is true, which is exactly what I want. It won't execute the function if the condition is false, e.g., in the code below if the business_name is null then it executes the branch_name function, other wise it returns the business_name.
SELECT DECODE ( business_name,
null, branch_name( p_record_id ),
business_name ) "Name"
FROM entity
WHERE record_id = p_record_id;

NVL Function on CLOB data type

Using insert command in NVL function

How can we use insert command in a NVL function
exapmle : INSERT INTO employee
VALUES ( (NVL ( (SELECT emp_id
FROM employee
WHERE emp_name LIKE 'Test'),
(insert into employee values((select max(emp_id)+1 from employee),'Test')))));
I mean i will check for the record to exist in the table and if not exist i will add it to the table.

I mean i will check for the record to exist in the table and if not exist i will add it to the table.The first thing caught my eye is this
max(emp_id) +1A real bad piece of code. Never do that. Ever thought about multi user environment? Use a SEQUENCE.
If you want EMP_NAME to be unique (Which looks strange to me), then just add a UNIQUE constraint. You dont try to do what oracle already does really well.

Compilation problems using NVL function in Pro*C subselect

NVL Function and Truncate Function in Template Builder

Hi Guys,
How would I use NVL function and Truncate function in the Word Template Builder.
These functions do not work in the Query Builder when i use SQL Query as the Dataset while creating a report.
I could not find examples in the Publisher Guide either.
Thanks
rkingmdu

Hi
How can you not use the functions in your query? Does the builder return an error? ow about just pasting your query into the report definition does the nvl/trunc work then ?

Problem Using NVL Function

I ran across a problem with the format of an ASCI output file of an SQL script. The problem I have is with handling a particular column that contains account numbers. The column is defined with 8 characters. However not every entry has data. I have several fields that don't have any information.
Originally in my script I had the following line that made the script fail:
LPAD(TO_CHAR(TO_NUMBER(konten_nr)),8,'0'),
I then changed the line to the following: (The script ran but now I notice that the formatting is wrong)
LPAD(TO_NUMBER(LTRIM(konten_nr)),8,'0'),
I attempted to use the NVL function that will return a value when there is nothing in the column field but it doesn't work. Does anyone know what I'm doing wrong?
LPAD(NVL(TO_CHAR(TO_NUMBER(konten_nr),'FM999999999'),'0'),8,'0'),

what is exactly your problem ?
you want to translater " 1234" in "00001234" ? then simply use to_char(konten_nr,'FM00000000') .
You want to translate " 1 1 1 1" in "01010101", then use replace(konten_nr,' ','0')
Give us some samples

There is an invalid number of arguments found in the function '@PARENTVAL

Hi
In a prior version of Hyperion, we had a business rule which pushed values down to to a child member
+Fix ( EE105, , @Children("FX entry"), &District, @UDA("Cost centre - primary", "DuplicateMbr"),C3090,[Opex_WriteScenario], [Opex_WriteVersion],&CurYear: &YearPlus6)+
Month = @PARENTVAL("Cost Centre");
Endfix;
We are moving across to Calc Manager in version 11.1.2.1 and the problem is that I now get the following error message:
An error occurred in: Calc Opex CC
There is an invalid number of arguments found in the function '@PARENTVAL(Cost Centre)'. .
Your assistance is appreciated.
Cheers

Check if you can validate this script again Essbase, I am sure you will be able to.
If I remember correctly there were few functions missing in calc manager which were fixed in the patches released.
Try it on the latest patch:
Patch 14265667: Patch Set Update: 11.1.2.1.104 for Oracle Hyperion Calculation Manager

Binding problem when using NVL function

Hello.
I have a problem with my ADF application (11.1.2.1).
I use VO with a query (database view) - pivot table.
If i use where clause like table.attr = :p_attr, everything works ok.
If i use where clause like table.attr = NVL (:p_attr, table.attr) and put a value in :p_attr (executeWithParam) , query executes as if there is a null value.
Debug console shows:
Binding null of type 12 for "p_attr".
Query with NVL works ok in sqldeveloper.
But in jdev, as if the table attribute isn't bind to bind variable.
If a just remove NVL function, it works.
Any idea?
Thanks.
Regards

Hello.
I enter 50 in p_depart parameter and click "ExecuteWithParams". Query is executed and shows records (pivot table).
But if i look at the log window i see that an empty query was executed first.
<OracleSQLBuilderImpl> <bindParamValue> [427] Binding null of type 12 for "p_depart"
<OracleSQLBuilderImpl> <bindParamValue> [428] Binding null of type 12 for "p_job"
<OracleSQLBuilderImpl> <bindParamValue> [429] Binding null of type 12 for "p_hire_od"
<OracleSQLBuilderImpl> <bindParamValue> [430] Binding null of type 12 for "p_hire_do"
Then, it is autoexecuted for the second time with parameter set to the value i inserted.
<OracleSQLBuilderImpl> <bindParamValue> [470] Binding param "p_depart": 50
<OracleSQLBuilderImpl> <bindParamValue> [471] Binding null of type 12 for "p_job"
<OracleSQLBuilderImpl> <bindParamValue> [472] Binding null of type 12 for "p_hire_od"
<OracleSQLBuilderImpl> <bindParamValue> [473] Binding null of type 12 for "p_hire_do"
The same happens in our query. But ours is much more complex and it takes a lot of time to first execute "empty" query and then with inserted parameter.
We cannot use it.
It looks like bug.

To_number function return Invalid number

Dear All,
We have problem recently regarding one of our query that using to_number function. It worked smoothly for 4-5 years until recently our client complaints that the query is returning error ORA-01722: invalid number.
This is the SQL Script -> SELECT * FROM <table_name> WHERE to_number(b) between :param1 and :param2;
* Column b is defined as VARCHAR2(20)
First thing that come to my mind is this error is due to invalid value entered by user. Using the solutions provided by users in this forum and internet, I created SQL a function that checks whether the value is numeric or not.
So, when I run the query (+SELECT b from <table_name> WHERE is_numeric(b) = 0 AND ROWNUM < 20+) this is the result that I get.
b
251567
251568
251569
251570
251571
(Up to 11 record; value from 251567 - 251577)
Is there any limitation on the maximum value that can be converted using to_number* function?*
I have search the solutions over the internet and I accept the solution/recommendation that we should not store numeric value on varchar/char column; but I hope somebody can explain why I can't use to_number to convert the above figures to numeric, because when I execute SELECT to_number('251567') FROM DUAL it doesn't returned any error)
Thank you in advance for any help or clarification on this issue.

Funny answer, Billy!
Sounds like: The world is evil, so you have 3 choices:
1. Implement a good world
2. Be a bad guy, too
3. Live with that bad world and its consequences
I guess, 930427 only asked for some protection...
If one has to deal with two external system to move data from one to another - you can't change either of these systems (1 or 2) and you can't afford to fail (3).
Sometimes blanks inside the numeric values are the reason for INVALID NUMBER, i.e. "123 456".
as simple
to_number(replace(VALUE_CHAR, ' ', NULL))
may help...

ORA-01722: invalid number while using TO_CHAR function.

Hi All,
I was using this query from around past 1 year and everything was working fine.
select to_char ( '2012/12/23','YYYY/MM/DD') from dual;
how ever from monday onwards , this is returning me with the following error.
ORA-01722: invalid number
The NLS_DATE_FORMAT is DD-MON-RR in my oracle 11g version.
Please help me regarding this.

Your date is in literal & your intended format so no need to format it again.
select to_char ( '2012/12/23','YYYY/MM/DD') from dual;
same as
select '2012/12/23' from dual;I don't know your need so same code to work!!!
select to_char(to_date('2012/12/23','YYYY/MM/DD'),'DD/MM/YYYY') from dualsunnymoon wrote:
where vale for ? is coming as '2011/12/23' from java.
the whole application has to be changed and retested.
>
It it comes as a text convert it to date TO_DATE('2011/12/23','YYYY/MM/DD') to use in comparison operators like =, != , > , < etc. Comparison operators used taking date as literal will give you wrong result.
Better to do it right even it takes huge effort.
