Hi,
The hibernate is generating the following error:
Caused by: java.sql.SQLException: ORA-00904: invalid column name.
The names of the column of my tables have the character "_"(ex. OBJECT_CODE), when there is not the character don't happen this error. My database is oracle, implementing "sequences generator"
Can anybody help myself?

Thanks.

Usually this happens when the column name is really wrong.

Enable the SQL output on stdout and execute the result query on SQL*PLUS or TOAD in order to see exactly which column has the wrong name.

Many of columns on my database contains the underscore ("_") character and all work correctly both on Oracle and other databases (e.g. SQL Server, MySQL, ...).

Bye.
