Hi, Is it possible to change the collation of a varchar column in place (without making a temporary column, copying data, dropping the original column, making it anew and copying the data back)? Would setting RDB$RELATION_FIELDS.RDB$COLLATION do the trick (and is it safe to do)? I've got several old production databases which have different collations on different columns (probably by mistake) and would like to sort it out. Also, does the RDB$RELATION_FIELDS.RDB$COLLATION somehow depend on the default character set of the database, or is it universal (i.e. does the collation code from RDB$RELATION_FIELDS.RDB$COLLATION always mean the same, or does a single code mean different collations in databases with different default character sets)? Apart from that, I've got a production database with the default character set NONE (sigh). I assume there's no way changing it, other than a fresh DB + pump, but just in case... has anyone come up with another idea? (the DB is almost 100 gigs)
Thanks in advance for any hints. Best regards Tomasz
