On behalf of Ronen,

The DB is not share, it is a separated DB

This often happens if you're trying to use the JIRA database with two separate JIRA installs, or you have other objects in the database (and sometimes, even if you're just reading the database externally).  Can you check and confirm that you have a single JIRA connection into the database, no other systems using it at all, and you've not added tables or other things into the database?
