Htmldb_item.select_list_from_query-report error: ORA-01722: invalid number

Hi, i am trying to create a tabular form
with one of the item's value depending on another item's value, but i have an ORA-01722: invalid number error
my application is:
DESC AC6LIS
ACLIS_SEQ_ID NOT NULL NUMBER(10)
ACLIS_TSG_ID NOT NULL VARCHAR2(5)
ACLIS_EDZ_ID NOT NULL VARCHAR2(3)
DESC VE1EDZ
EDZ_TSG_ID NOT NULL VARCHAR2(5)
EDZ_ID NOT NULL VARCHAR2(3)
EDZ_DESCRIZ VARCHAR2(50)
select ACLIS_TSG_ID, htmldb_item.select_list_from_query(2,ACLIS_EDZ_ID,'select EDZ_DESCRIZ, EDZ_ID from ve1edz where ve1edz.EDZ_TSG_ID ='||ac6lis.ACLIS_TSG_ID) edz_select_list from ac6lis
Any Help?
Thans in advance
Costantino

When your inner SELECT statement is firing it is doing a type conversion. It is seeing a number value in 'ac6lis.ACLIS_TSG_ID' and trying to do a number comparison with 've1edz.EDZ_TSG_ID'. 've1edz.EDZ_TSG_ID' has a non-numeric value in one of the rows which results in your error. To correct this place quotes around the value of 'ac6lis.ACLIS_TSG_ID' like:
select ACLIS_TSG_ID,
htmldb_item.select_list_from_query(2,ACLIS_EDZ_ID,'select EDZ_DESCRIZ, EDZ_ID from ve1edz where ve1edz.EDZ_TSG_ID ='''||ac6lis.ACLIS_TSG_ID||'''') edz_select_list
from ac6lisMike

Getting ORA-01722 - Invalid number error in SQL

I am trying to run a query like
SELECT NVL (ic.industryclassdesc, 'NULL') industryclass,
NVL (hci.updated_by, 'NULL') updatedby,
NVL (hci.operation, 'NULL') operation,
hci.audittimestamp audittimestamp
FROM xxx_company_inxxxx hci, xxx_industry ic
WHERE hci.company_id = 9079496
AND ic.industryclassid = hci.industryclass_id
ORDER BY DECODE (hci.operation, 'D', 'X', hci.operation), hci.audittimestamp
And getting the error - ORA-01722 - Invalid number.
But the columns - ic.industryclassid, hci.industryclass_id and also hci.company_id are 'Number' datatype and also not nullable.
Can anyone suggest a approch

SELECT NVL (ic.industryclassdesc, 'NULL')
> industryclass,
NVL (hci.updated_by, 'NULL') updatedby,
NVL (hci.operation, 'NULL') operation,
hci.audittimestamp audittimestamp

hci.audittimestamp
And getting the error - ORA-01722 - Invalid number.
Do not enter 'String' in the nvl function,if the column is number datatype,

Varchar to number returns a ORA-01722-Invalid Number error

I have a script where i am converting a varchar to number to be compared against a number.
(To_Number(p.result_value,'999999.99') < 0 OR p.result_value < 0)
this particular line is causing the error ORA-01722-Invalid Number.
Is there any ideas as to why this happens and how I can resolve?
Thanks in advance!

The result_value column in Pay_Run_Result_Values is a varchar2 field.
So you need to put in some additional logic to make sure that the row is having numbers alone before doing to_number.

ORA-01722: invalid number error coming in Oracle 10g.

Hi,
We are getting the error "ORA-01722: invalid number" while opening a cursor using CURSOR FOR LOOP.
This error has started coming only after we have migrated to Oracle 10g from Oracle 9i. Earlier the same code used to work properly. And also on Oracle 10g, its not happening every time. Sometimes it gives error while sometimes it works.
Does anybody know about any such bug in Oracle 10g. Our cursor is a parametrized cursor accepting a VARCHAR2 parameter and the value we are passing to it is also character.
Our database is Oracle 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production and is running on UNIX server.

And also on Oracle 10g, its not happening every time. Sometimes it gives error while sometimes it works. This is typically due to
a) environment settings that differ from session to session
b) or more often, data
The actual error means that Oracle expects a number and is unable to obtain a number from the input (data or SQL or bind variables) supplied. I agree with William that it looks a lot like an implicit TO_NUMBER() conversion failing.
Why not add a debug exception handler to the code? When that exception occurs, dump the PL/SQL call stack and values of all variables and parameters to a debug/logging table (using an autonomous transaction).

Getting error as ORA-01722: invalid number

Hi below is my query
select count(1) from table1 where table1.rqstid = '83041' AND table1..score_name = 'Small Business Credit Risk Score' AND
to_number(table1.total_score) >= '70' and rownum<2
I tried to convert '70' to 70, but still I got ame error.
In table1 total_score is varchar2(30) data type, but for this rqstid the data is 420, so it should convert 420 to number and compare with 70.
But why I am getting this error? Please help.
If I remove to_number conversion fot total score then this error is not coming, but this will not give correct result for me.
Thanks.

CREATE TABLE SBE_SCORE (
RQSTID VARCHAR2 (30) NOT NULL,
SCORE_NAME VARCHAR2 (300),
TOTAL_SCORE VARCHAR2 (30),
RISKLEVEL VARCHAR2 (30),
SUBSCRIBER_ID NUMBER (10))
INSERT INTO SBE_SCORE ( RQSTID, SCORE_NAME, TOTAL_SCORE, RISKLEVEL,
SUBSCRIBER_ID ) VALUES (
'83041', 'Small Business Credit Risk Score for Financial Services', '420', NULL, NULL);
My Query was
SELECT
count(1)
FROM
sbe_score
WHERE
sbe_score.rqstid = '83041' AND
sbe_score.score_name = 'Small Business Credit Risk Score for Financial Services' AND
to_number(sbe_score.total_score) >= '70' and
rownum<2
Error:ORA:01722 Invalid Number
Now I have modified as below and I am able to get correct results
SELECT
count(1)
FROM
sbe_score
WHERE
sbe_score.rqstid = '83041' AND
sbe_score.score_name = 'Small Business Credit Risk Score for Financial Services' AND
to_number(translate(lower(sbe_score.total_score),'abcdefghijklmnopqrstuvwxyz@._','0'))>= 70 and
rownum<2
I I omit r in the translate function then I am getting same error Invalid number, So just I want to know whether the data 420 for total_score is taking "r" internally? withou our knowledge?

ORA-01722: invalid number performing List of Values query

I have a situation here where I want to pass string value(available in search field) to POP up key LOV on another page as default value.
I passed item value in default field in POPup key LOV item.I am able to see string value but It also gave me following error.
Error: ORA-01722: invalid number performing List of Values query: "select CUSTOMER_NAME, CUSTOMER_ID from (select customer_name, customer_id from hed_customers) wwvlovinlineviewname where CUSTOMER_ID = :WWV_LOV_RETURN_KEY_UTIL_1111".
Without Default value, it work like champ.
Please suggest how to get rid of this error
Thanks in advance

I hit the same problem.
The thing is that, in APEX, a 'null' value in a form is not really null but gets passed on as '%'.
When that gets compared to a number, 01722 will occur.
A workaround is to define a 'value if null' that is an implicit number, like '-1'.
And lets hope no one ever uses that as a real ID...
Cheers

I am doing it with the help of the importer tool in the SQLDeveloper, by doing a right-click onto the table and selecting import data. In the assistant everything seem to be fine, even the data preview.
But when I try to import, I get an error: "ORA-01722: Invalid number" and a couple of failure windows appear. These windows display a NullPointerException:

As one can see, the numbers are quoted ('). If I delete the quotes by hand, the insert statement works correctly.
What can I do, so that the import tool does not quote the numbers?
Deleting the quotes with the help of a regular expression is not workaround, since a lot of error windows appear, which needs to be closed by hand...
Thanks in advance,

Microsoft Access shows "ORA-01722: Invalid number"

Hi,
I have seen a previous post on this problem, but none of the tips applied to my situation, so I'm asking again.
I'm accesing Oracle 8i Personal (German Version) with Access 2002 (latest SP, on a computer with Windows 2000). Please note that I installed the latest ODBC driver from Oracle (8.1.7.6.0). When I create a table which has, say, a NUMBER(10,3) field in it, and I link it into Access using the ODBC driver, I cannot enter numbers like "1,23" into the table. The error "ORA-01722: Invalid number" is shown and the INSERT fails. If I enter the numbers like "1.23", the resulting field value is "123". The
problem occurs, whether I use the table view, a form or VBA via ADO. Pass-Through queries (over ADO's QueryDef facility) work, however. The decimal separator is "," in both Windows and Oracle. With normal NUMBER fields everything works fine.
When looking at the SQL log it turns out, that Access hands out a string to the ODBC driver and relies on the driver to convert it to a number. Regardless of the locale set in Windows, Access uses the dot ('1.23') as decimal separator for this string. The German version of oracle wants a comma as decimal separator as in "INSERT INTO TEST VALUES ('1,23')". From a previous post I know that ODBC specifies that all numbers must use the dot, regardless of the locale setting. So it turns out, the Oracle ODBC driver is causing the problem, not Access. But, anyway, this problem could easily be fixed by adding a "Workaround option" to the ODBC driver, that always converts dots in numbers to commas before handing it out to the backend. Another option would be, that the ODBC driver does this decision automatically by asking the backend, which separator it wants.
Any comments greatly appreciated.

This is actually a duplicate of bug# 1938991 which says:
"A 'Numeric settings' option has been added to the Application Options page of the ODBC Configuration screen so that the user can choose what numeric settings will be used in receiving and returning numeric data that is bound as strings. This option allows the user to choose Oracle NLS settings (the default setting and the behavior in former releases), Microsoft default regional settings (to provide a way to mirror the Oracle OLE DB driver's behavior for greater interoperability) and US numeric settings, which are necessary when using MS Access or DAO in non-US environments. In this case, setting the Numeric settings to US settings should resolve the issue, since DAO is expecting the data in US format."
Apparently the fixed release is 9.2.0.2, 9.0.1.4 or 8.1.7.7 depending on your client version.

EXECUTE IMMEDIATE ORA-01722 invalid number

hi all
i have a plsql procedure in which the following statement which gives this error ORA-01722: invalid number
sql_stmt :='UPDATE Student set '||stu_gradefor||'=TO_NUMBER('||stu_marks||') where UserID='||stu_UID;
EXECUTE IMMEDIATE sql_stmt;
here all variables (stu_marks,stu_gradefor and stu_UID) are varchar2 coming from different procedure(form) but in the table named Student column HW1 (stu_gradefor) is of datatype number.
I have tried a lot but could not make it to work. Is it that we cannot enter an number through EXECUTE IMMEDIATE? If Possible can somebody help me with this?
Thanks a lot.
Regards
Jyoti

create table Student(UserID varchar2(8) not null, HW1 number(3) , HW2 number(3) , PA1 number(3) , ................);
create table Domain(R_Domain varchar2(11) not null, R_Status char(1) not null, R_Date Date null,R_Value varchar2(11) null, R_Mean varchar2(300) not null);
insert into Domain( R_Domain, R_Status, R_Value, R_Mean )values(
'Term','t','PA1','First Programming Assignment');
Full names for HW1, HW2, PA1....are in the Domain table. so in variable stu_gradefor we get the R_Value.
this is true :variable stu_marks is not actually a number, so the TO_NUMBER is causing the error. stu_marks is of datatype varchar2 but the field HW1,.. are all expecting a numeric value.
i tried SELECT TO_NUMBER(stu_marks) INTO gmark FROM DUAL;
sql_stmt :='UPDATE Student set '||stu_gradefor||'=(:1) where UserID='||stu_UID;
EXECUTE IMMEDIATE sql_stmt using gmark;
where gmark is a number but noting works.same error
This can be true:the column userid is a varchar2 column with a mix of numeric and alpha numeric values. userid value that i inserted was'12345678'
i there any other way to handle this situation?
Thanks for replying

ORA-01722 Invalid Number Error - report parameter

I have a report which runs successfully using the following simple select statement: -
select u.user_id, u.user_forename||' '||u.user_surname user_name,
fo.flight_number_in, fo.sta, fo.ata, fo.flight_number_out, fo.std, fo.atd
from users u, flight_operations_employees foe, flight_operations fo
where NVL(fo.sta, fo.std) between :P_Start and :P_End and
fo.record_number = foe.record_number and
u.user_id = foe.user_id
order by u.user_surname
Where P_Start and P_End are parameters passed from a form. I want to add further user option selections for the report and have added another parameter (P_inClause) where the user can select one or more items to select from. The column selected is a number on the table. I then want to pass this as another parameter into the report listing a number of valid values using the IN statement. The updated select statement is: -
select u.user_id, u.user_forename||' '||u.user_surname user_name,
fo.flight_number_in, fo.sta, fo.ata, fo.flight_number_out, fo.std, fo.atd
from users u, flight_operations_employees foe, flight_operations fo
where NVL(fo.sta, fo.std) between :P_Start and :P_End and
fo.record_number = foe.record_number and
u.user_id = foe.user_id and
u.user_id IN :P_inClauseorder by u.user_surname
u.user_id is a number column in the table. The value of P_inClause is set as a character parameter in the report and has the value (45,5,13,26) - as an example.
When I try running the report interactively it comes up with the ORA-01722 : Invalid Number error and points to the P_inClause parameter. If I type in the value directly into the select statement it works fine.
Do you have any ideas as to how I can make this work?
Regards

'ORA-01722: Invalid number' error message in BeX

Hi Gurus,
We have a new report built on top of a DSO. When I run this report, I get the message 'ORA-01722: invalid number'. On furthur testing, I found that when I move two objects 'Date Changed' & 'Time Changed' [both are 'Z' objects we created] from the 'Rows' to 'Free Characteristics', the report runs as expected. So the issue seems that it is with these two objects. One of them is of type 'DATS' & the other of type 'TIMS'. These two are mapped to respective 'Date' & 'Time' fields in SAP R3.
SID's exists in the Master Data tables for both these objects. The data for both the fields contains the normal 'Date' & 'Time' values.Running the query using RSRT shows the same error message. The RSRV check on this report says that 'Query execution not possible as the variables contain invalid values'.
I have seen a couple of other posts in SDN with similar issues but none of them have a solution identified so far. Just wanted to check if anyone who has experienced this issue have been successfully able to resolve it?
Thanks
Arvind

Hi Ravi,
Thanks for your prompt reply. Yes, the 'Date' & 'Time' objects have 0DATE & 0TIME as reference objects.
I couldn't find any invalid vallues for these date and time fields. If invalid values were present, wouldn't the DSO activation have failed?
Thanks
Arvind.
