I try to insert some records in a table and this well-known message appears: "ORA-00001: unique constraint (xxx_xxx.proj_01_UK) violated". Therefore, I know that each row that I try to insert is unique and not already in the table. Is there another reason for wich Oracle could call this error?

Check whether you are inserting two NULL values.
