Hi, I encountered the demand to store the euro sign. With the current character set impossible. So I have to migrate to a new one. Docs state alter database character set is possible when new character set is a superset. Alternative is to export and import which is not a realistic at this time for this organization. I have 2 questions: 1) My current character set is WE8ISO8859P1, I understood WE8ISO8859P15 does contain the euro sign but is this a superset? 2) Any experiences with alter database character set? Is this a solution without risks? I have about 3 tables with either long or clob type fields so I might have to export and import those only, but these are not about currencies so should I export those? Hope you can shed some light on this, Tnx, Jeroen
