I’m experiencing (what looks to me like) the same problem Felipe had back in 2009 with the DDL extract prefix. Our team uses the schema prefix option but when we perform the extract we get <schema_name>_<object_name> where there is an underscore rather than a period as a separator.
Is it the end of the world? no… but our standards require us to use the period and, well, it’s a state agency so you know what sticklers we are for process and procedure
I can’t locate where this was handled previously, but is it possible that the old fix got lost when 6.5 was compiled? And is it not an issue in 6.6?
