Hi, ISO seems to allow spaces among the digits of a binary literal, so as to group them for readability, as in X'00ba b10c'. We seem not to. (The B'...' form appears to be a PostgreSQL extension, but I imagine if ISO had it, it would allow spaces too.)
Is it worthwhile to allow that? Or to add a compatibility note somewhere around sql-syntax-bit-strings saying we don't allow it? For comparison, byteain does allow grouping whitespace. It seems that byteain allows arbitrary whitespace (tabs, newlines, etc.), whereas ISO's X'...' allows exactly and only U+0020 space characters. Whitespace for byteain must occur between digit pairs; spaces in X'...' per ISO can be anywhere. Regards, -Chap
