Well, the SQLX group seems to moving partiulcarly slowly. In the past year all I've seen come from them are a press release or two and a fairly cumbersome document that describes mappings from SQL types to XML types which seems to contain some information based pre-recommendation version XML schema[0]. I assume that since IBM and Oracle are members of SQLX, we're going to see the creation of an XMLType in SQLX and extensions to SQL that allow one to perform XPath queries over XMLType columns. Since MSFT and Sybase are also on the SQLX board, I wonder if they will adopt similar a XMLType construct (I know that SQL Server has none but know not off Sybase) and if so whether they'll stick to alowing queries in a subset of Xpath 1.0 / Xpath 2.0 or even XQuery? Interesting times... Reminds me of OODBMSs and RDBMSs all over again with all the object-relational hoopla.that sprung up around that. [0] Document refers to xsd:timeDuration and xsd::timeInstant types. -- THINGS TO DO IF I BECOME AN EVIL OVERLORD #35 I will not grow a goatee. In the old days they made you look diabolic. Now they just make you look like a disaffected member of Generation X. _________________________________________________________ Do You Yahoo!?
