Assertion Failure

Alexsandro Afonso MOura · Post by **Alexsandro Afonso MOura** » Fri 03 Dec 2004 15:52

I'm using ODAC 3.30 with Delphi 5.0 and Oracle 9.

Sometimes, when opening a query, my application gives the exception:

Project pSaltm.exe raised exception class EAssertionFailed with message 'Assertion failure (D:\Projects\Delphi\Odac\Source\OraClasses.pas, linha 1330)'. Process stoped. Use Step or Run to continue.

It is not in an especific point neither a moment, but it usually happens when selecting from a table that is frequently accessed by others applications for inserting, updating and deleting and has about 250000 records.

In time, there's no D: drive in the machine and 'linha' means line in Portuguese.

Thanks,

Alex

I've been receive exact this message, when used a TDBMemo with varchar2 data type, and no data in this field when trying to Post.
Just fill it with space and problem will disappear.

Assertion failure can happen if you receive any kind of unexpected error. It can be the different problem. Are you sure that line number was 1330.

I still have a project where i've used a lot of odac functions and options. I've found some conditions when different errors are occuring. And i've found a ways to avoid this errors. I can test this and oter situations again, but i have no latest version of ODAC.
