It says that your sequence doesn't exist in your database
ORA-02289: sequence does not exist
Are you sure 1) the Oracle database is running (Most likely) 2) you app is connected to it (Most likely) 3) You are connected to the correct database (Maybe/Maybe not) 4) There is actually a sequence table called "CUSTOMER_ID_sequence"
Or maybe, which I doubt that it might be case sensitive?
I had The same Issue,
then later on I found that the sequence Iam trying to use was not there in the database,
after creating the sequence it worked fine for me.
Thanks to Mark Spritzler for raising those questions.
Madhu.
Don't get me started about those stupid light bulbs.
