Re: question on ValueIdSet::isNotNullable

Hi Eric, I think the reason this method does not consider AND is that a ValueIdSet should not contain any AND predicates, since the set itself assumes an ANDing of all of its members. So, instead of a single member AND(an>=20, an<=30), the ValueIdSet should contain two members: an>=20, an<=30, in

Re: enhance TRANSLATE to support Chinese charset?

Hi, Kevin's question make me think of another question: The TRANSLATE function takes a value a with character set ca and translates it into a new value b with character set cb. Since we don't support GBK as character sets in data types, I wonder how we could call this function. People may in some
