Examples of ERXPrimaryKeyListQualifier

er.extensions.eof.qualifiers.ERXPrimaryKeyListQualifier
The primary key list qualifier is used to generate a qualifier that can be used to filter a result set for a given set of primary keys. Note that this uses the IN expression and as such may not work with some databases.

Given a list of EOs, this generates a query looking like ... t0.ID in (< the list of primary Keys for EOs in the list>) .. this is useful for pre-fetching type uses.

    protected EOQualifier qualifierForArray(String key, NSArray objects) {
        if(objects == null)
            return null;
        if(objects.count() == 0)
            return new EOKeyValueQualifier(key, EOQualifier.QualifierOperatorEqual, null);
        return new ERXPrimaryKeyListQualifier(key, objects);
    }
