Hey all- for a new search tool I'm writing, I'm thinking it might be prudent to use XML transformations to convert between some various query formats. Is anyone out there aware of an XML schema that could represent a SQL select statement? You know, something like this <select> <what-list> <what-element>a.*</what-element> <from-list> <from-element> <table>asset</table> <alias>a</alias> </from-element> </from-list> <where-list> <where-element>a.asset_id = 500</where-element> </where-list> </select> But with support for hierarchical queries, joins, and other nasty business.
