[OJB-developers] OJB OQL

[Jakob B. <jbr...@ho...>]

hi,

this patch fixes problems with OQL nil and between.

query.create("select persons from brj.ojb.Person where geburtsDatum = nil");

here the grammer was going into the equalityExpr method and did not
recognize "nil".

query.create("select persons from brj.ojb.Person where test between $1 and
$2 and name like $3");
query.bind(new Integer(80));
query.bind(new Integer(100));
query.bind("%er");

in this case the bind assumed that each criterion should have only one
parameter
and looked for three criteria in the above example.

i have to admit i'm neither an antlr nor an oql expert !
