ORA-01426: numeric overflow, while migrating "float" values

When I try to insert a value of *2.58612749363472E302* (originally a "float" in SQL DB) into an Oracle column of type float(126), I get this error "ORA-01426: numeric overflow"
I tried changing the column type to BINARY_FLOAT, BINARY_DOUBLE, but I still get same error.
I'm using Oracle SQL Developer (2.1.1.64.45) to migrate a SQL Server 2005 Database to Oracle 11g.
Do you have any thoughts on this? Or workarounds?
Thanks in advance.
Arul

Arul,
I have checked the Migration Workbench documentation where it says for float data -
Oracle® SQL Developer
Supplementary Information for Microsoft SQL Server and
Sybase Adaptive Server Migrations
Release 2.1
Table 2–2 Data Types in Oracle and Microsoft SQL Server or Sybase Adaptive Server
NOTE: If you try to migrate
floating point data greater
than or equal to 1.0E+126
then SQL Developer will fail
to insert this data in the
Oracle database and1 will
return an error.This also
applies to negative values
less than or equal to
-1.0E+126.
So, if I understand it correctly your value of 2.58612749363472E302 is outside this range.
Regards,
Mike

ORA-01426: numeric overflow when creating job

Hello,
When executing the following script to create a job I get the error "ORA-01426: numeric overflow" . When I execute the same script on another database with same version and same configuration I do not get the error and the job is created.
Can anyone help me out solving this issue?
Script:
DECLARE
X NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT
( job => X
,what => 'insert into dba.dba_logs values (''SGC'',''TRL03'',sysdate,null);
commit;

,no_parse => FALSE
SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || to_char(x));
COMMIT;
END;
Database version: 11.2.0.1
OS: HPUX

We are planning to migrate to dbms_scheduler, but that's in the future. for now we have this error first to solve.
We also tried the following with dbms_scheduler and it gives the same error. The strange is that in another database with same version and same OS it works fine.

Our cube builds starting failing and we received this error after the cube log table sequence reached 32787.

Could somebody please explain with me examples as when you get this error.

Thank You for your help.

You get 1426 when a number, usually from a caclulation, is too big, or too small for Oracle to represent. For example:

Error ORA-01426: numeric overflow when Creating table with double data type

Hi,
I am using ODP.NET to create a table with data from SQL to Oracle. The problem is with double data type fields that is equivalent to FLOAT(49) in Oracle. My syntax is:
CREATE TABLE SCOTT.ALLTYPES

F2 NUMBER(10),
F3 NUMBER(5),
F4 NUMBER(3),
F5 FLOAT(23),
F6 FLOAT(49),

F9 NVARCHAR2(500)
Th error is with field F6 but I am not sure what is the correct type equivalent to double in SQL.
I woul appreciate if anyone can help me with this problem.

Function - numeric Overflow error

Dear All,
I have a function that is causing a ORA-01426: numeric overflow error
My values from the variables are as follows
v_highest_Uprn is 10033233499
v_start_uprn is 10033223500
Any ideas how to fix this. Thanks in advance.
FUNCTION get_next_uprn RETURN NUMBRT IS
/* Loop through numbers betweeen the next_uprn and the highest in the active range. */
/* Check to see if the new uprn exists in the database , if no rows returns then return the new uprn. */
v_start_uprn NUMBER;
v_highest_uprn NUMBER;
v_uprn_exists NUMBER;
v_new_uprn NUMBER;
BEGIN
SELECT next_uprn ,
highest_uprn
INTO v_start_uprn,v_highest_uprn
FROM PD_PROPERTY_NUMBERS
WHERE active_sequence = '*';
v_new_uprn :=v_start_uprn ;
FOR rec IN v_start_uprn..v_highest_uprn LOOP
IF v_new_uprn > v_highest_uprn THEN
Bs7666_Standard.bs7666_error(35635);
END IF;
SELECT uprn INTO v_uprn_exists

END LOOP;
RETURN v_new_uprn;
EXCEPTION
WHEN NO_DATA_FOUND THEN
RETURN v_new_uprn;
END get_next_uprn;

Hi
The loop control variable in a FOR loop is an integer (or similar) it seems; those numbers are simply too big for it.
Change your code to something like:
FOR rec IN 1 .. v_highest_uprn - v_start_uprn + 1 LOOP

Unexpected Numeric Overflow on empty tables when scanning with DMU

I have an instance of oracle running on an isolated network (oracle 11.2.0.3), on a Windows Server 2008 r2, x64 dell R705 server
When using the DMU to scan tables, I get the following error:
ORA-01426: numeric overflow
DBMS_DUMA_INTERNAL: line 8
DBMS_DUMA_INTERNAL: line 43
at line 1
I get his on multiple tables, but in each case, the table is empty (0 rows)
Can I safely ignore this? How do I get DMU to ignore the errors and continue?
Thanks in advance.

The fix for bug 8743409 is not included in the 11.2.0.1 release. Please check the DMU supported configurations. In order to use DMU on any versions of the database before 11.2.0.3, you need to apply a prerequisite server-side patch on one of the supported configurations. If you can upgrade to 11.2.0.3, there is no need to apply additional patches and the aforementioned fix is included.

Numeric overflow with DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE

Hello all-
I'm running Oracle 9i on WinXP sp. 2.
I'm trying to create a CDC table with the standard SYS package and am getting a numeric overflow error. The code I'm attempting to execute is this:
BEGIN
sys.dbms_cdc_publish.create_change_table(
OWNER => 'CDC_USER',
CHANGE_TABLE_NAME => 'PA_BUDGET_ENTRY_METHODS',
CHANGE_SET_NAME => 'SYNC_SET',
SOURCE_SCHEMA => 'PA',
SOURCE_TABLE => 'PA_BUDGET_ENTRY_METHODS',
COLUMN_TYPE_LIST => 'BUDGET_ENTRY_METHOD_CODE VARCHAR2(30)',
CAPTURE_VALUES => 'NEW',
RS_ID => 'N',
ROW_ID => 'Y',
USER_ID => 'Y',
TIMESTAMP => 'Y',
OBJECT_ID => 'N',
SOURCE_COLMAP => 'N',
TARGET_COLMAP => 'N',
OPTIONS_STRING => NULL);
END;
The error I'm getting is this:
ORA-01426: numeric overflow
ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 299
ORA-06512: at line 2
This happens every time, regardless of the source table i'm trying to capture changes for.
Clearly this is a normal exception (i.e., not only thrown in the CDC packages) so I'm having a hard time figuring out what it could be. Anyone out there familiar with CDC have any thoughts?
Thanks in advance,
James

I tried that but no luck yet, also tried put all in a single line, but the same error. It doesn't something tricky here, but actual problem with package. "ddl_markers" is new to 11g and not much documentation is available on that.
Also setting ddl_markers=N removed 3 columns from Publisher table, and the effect of it on Subscriber's view is still a gray area,

Exp function and numberic overflow ORA-01426

I've got a problem that has been driving me slightly mad over the past few days. I have been trying to code some actuarial functions that I don't really understand for a data warehouse load on Oracle 9.2.0.6
I am trying to use exp() and power() functions in an insert statement. There is some slightly dodgy data in the source table that is causing a numeric overflow to occur for some rows so I have written a function which calculates the values and returns the result. If an exception occurs, this will be caught and the result set to 0.
The problem I am finding is that within the function, the power() function will successully raise a value_error exception when a problem occurs. However, the exp() function will not. When calling exp() with a large number as the parameter, it will simply return 1e126, which will subsequently cause a numeric overflow when calculating the value for another column.
However, the number overflow will be raised if I use select exp(...) into ... from dual
Is this just a weird inconsistency between the SQL and PL/SQL engine. I thought these problems had been resolved with Oracle 9 but I guess not.
I think I can probably work-around the problem for here, just looking for confirmation that my thoughts are correct.

I hadn't realised that 9.2.0.8 was the most recent patch set for Oracle 9i or that we were a couple of patch sets behind. Maybe I'll have to chase that up but I'm sure we've got a reason for not patching. Whether that would be a good reason or not is probably debateable.
An upgrade to 10g or 11i is in the pipeline but it is currently moving at glacial speed.

Ora-01426 error

Hi,
If i execute the below pl/sql, i am getting Numeric over flow error.
declare
t number;
begin
t :=788888888*305;
end;
ora-01426 Numeric over flow
Ora-06512-Error at line No:4
I am not getting this error, if i use decima point in 788888888.0*305
Is this Oracle bug?
Regards,
Latha

While I am very hesitant to label something a bug I think you've got one here.
Please open an SR at metalink and report it.
I'd do so myself except you didn't post version, platform, and other critical information.
I just duplicated the behavior on Win XP with 11.1.0.6.
I can do this:
select 788888888*305 from dual;
and this:
SQL> create table t (col number);
Table created.
SQL> insert into t values (788888888*305);
1 row created.
without problem but what you demonstrated fails. Please post the bug number when you get it. Thanks.
