Question:

The database field ORDER_ID is of type number(7) but I mapped it to string for certain reasons. Is it OK to do that? It does seems to work but when we ran the load test we do get following error every once in a while

Full stack trace of exception that occurs:

Name and version of the database you are using:
Oracle 10g

More info

The Order id is generated by some other process and I just want to use the generated id to pull the right record and later make the update. I know there is one generator "assigned" that might be usefull in this situation but I read in the documentation that it is the default one. So I assume it is already being used.

Any help will be greatly appreciated. Thanks

Faikeeyes,

Maybe your ID property is null and the object cannot be saved? If could add this extra test and re-run your load testing ... most reproducible code problems are solvable problems :)

mseritan,

You did not tell me if maping "String" to number field is OK? Please let me know thanks.


Faikeeyes.

Hi,

I am sorry I never used this mapping. You said you have to use it, so why not just give it a try. If you can read records, update and write back then you are all set.

If you are not comfortable with the approach ever after testing it you can also provide a second set of accessors. You can leave setId(), getId() to the native Integer/Long and add a setMyId(String) that converts explicitly.
