Hello guys,
I have a problem with my web application and postgres. I have several servlets
on a page which results in severeal simultaneous data base calls kind of:
SELECT d.id, d.aa, d.ab, ts.ac, d.ad, d.af, d.ag, d.ah, d.ai, d.aj, d.ak, d.al,
d.am, d.an, d.ao, d.ap, d.ar, d.as, d.at, d.au, d.av, d.ax, d.ay, d.az, d.ba,
d.bb, d.bc FROM c_depots d INNER JOIN c_aa ts ON d.bd_id=ts.id INNER JOIN
cx_users_depots cx ON cx.id_depots=d.id INNER JOIN c_users u ON
cx.id_users=u.id WHERE d.id=13
Even though I have "d.id 13" the SELECT result is empty. When I'm working with
delays in the servlets, everything works fine. The calling instance itself is
realized as single instance:
public static DbManager getInstance() {
if(instance == null) {
instance = new DbManager();
}
return instance;
}
So I'm wondering why there are such problems and how can I resolve them?
My posgres version is (still) 8.2.
Thanks.
