There are. Or rather, there is one: 0x80000000 - 0xFFFFFFFF map to negative INTEGER values, whereas 0x080000000 - 0x0FFFFFFFF map to positive BIGINTs. But I see Helen has taken care of that in her latest commit. > As for BETWEEN and the others: maybe precedence is totally irrelevant > for "comparison predicates". I just mentioned it since "comparison > operators" have defined precedence. According to IBPhoenix's Using Firebird and Helen's Firebird Book, BETWEEN...AND, LIKE, CONTAINING and STARTING [WITH] all have precedence 9 (lowest) among the comparison operators. I assume that the same is true for SIMILAR TO. > I've spent most of Easter in hospital, and haven't really been keen on > doing testing. Sorry about that. Hope you're doing alright now!
