Hibernate Query Restriction: NULL or Trim Whitespace Empty-String -


added child-table issue

one of hibernate query restrictions either null or trimmed-empty string.

the following or-restriction trim(..) doesn't work because it's not sqlrestriction.

final criteria query = sessionfactory.getcurrentsession().createcriteria(peoplet.class);  query.add(restrictions.or(       restrictions.eq("trim(childtable.commenttext)",""),       restrictions.isnull("childtable.commenttext")) );

the error is

org.hibernate.queryexception: not resolve property: trim(

but can have 1 or part sqlrestriction , other plain restriction? way handle test? note: have child table here.

try this:

add(restrictions.sqlrestriction("{alias}.trimcommenttext) = ?", ""), stringtype.instance))

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
