EMF. Javadoc. Screencast. Comparison of different SQL implementations. The goal of this page — which is a work in progress — is to gather information relevant for people who are porting SQL from one product to another and/or are interested in possibilities and limits of 'cross-product' SQL.
The following tables compare how different DBMS products handle various SQL (and related) features. If possible, the tables also state how the implementations should do things, according to the SQL standard. I will only write about subjects that I've worked with personally, or subjects which I anticipate to find use for in the near future.
