We have to change all of our usernames to 6 digit numbers..
I can create users in Oracle Database with all numbers.. I can log into Oracle Forms and BI with a username that is all digits..
But I know there will be problems... for example
connecting through a database link with all numbers as the userid will error with ORA-00987: missing or invalid username..
However, I can get around this by putting the username in quotes "000000" and then it works..
So my question is, are there any other problems I will run into?
