the switching costs, in my opinion, have more to do with the non-SQL aspects of the RDBMS implementation than with SQL itself.

I think it's both. You pointed out that my example query would run the same on all database platforms. True, but that was a very simple query. Give me something with a few outer joins in it, and I'll have to code it differently for every database on the planet! ANSI-SQL will help once the RDBMS's become adequately compliant with it, but you can still write a syntactically correct ANSI-SQL query whose functionality is not supported by the underlying database engine. (Nested outer joins are a killer!)

Maybe the adoption of SQL was really an end-run around the "open" part of "open proprietary architecture"! &ltg&gt
