> Table 1, SQL Boolean Operators, at <URL:http://db.apache.org/derby/docs/dev/ref/rrefsqlj23075.html>
lists the comparison operators <, =, >, <=, >=, <>. Derby also accepts !=,
which I believe has the same meaning as <>. The != operator should be documented along
with the other operators. (I haven't checked whether != is standard SQL.)
