There is no real way to write "database[-]agnostic" SQL, although of course
middleware code can and should be.
SQL dialects cannot even agree on simple things like the syntax for VARCHAR
(VARCHAR2 in Oracle) or the semantics of TIMESTAMP, or what is legal in a
SELECT. As Sim Zacks said, "you lose most of the advantages of the chosen
database engine" if you write to the lowest common denominator, particularly
as such an LCD is nonexistent.
