Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Hi,

I have had a strange behavior when i tried to run a statement against an Oracle database 10g R2.

the statement is pretty simple and Col1 is Number(8);

select * from toto A where A.col1=1;

No row returned

The other statement is :

select * from toto A where to_number(A.col1)=1;

And it returns rows.

For additional information, the tabe is partionned by range on col1.

Regds,

AB
