I believe this page should be helpful:

The 2nd answer says:

You can specify them in the file '/data/local.prop' as follows:

log.tag.MyAppTag=WARN

So I guess that the following should work to only show ORMLite warn messages:

Hi, is there a way to disable the logging using the AndroidLog
implementation?
I'm seeing a lot of create table log lines of the TableUtils class and I
want to remove them from my release version.
Thanks,

Hi Salil

The problem might be with how you setup/populate your foreign collection in the first place.
Does your Reading class have a database field called device with foreign=true?
Then when you instantiate your Reading initially do you associate it with the device properly like this?
Reading theReading = new Reading();

Hi Salil
I understand the problem as being your inability to access the device's readings.
Perhaps the relations in your db aren't properly configured?
How did the Readings get into the db?
And when the readings were inserted into the db was the relationship between the reading and the device properly established?

Hi Moritz,

I meant to say that devices and readings are already there in the database.
I am merely querying the device (which is successful) and the corresponding
readings through the ForeignCollection field of that device (which is not
successful).

Salil

Hi Salil
Readings aren't instantiated for you automatically.
Somewhere in your code you'll have to create them and associate them with the appropriate device so that the device's foreign collection gets populated properly.

Hi Moritz,

Yes, my Reading class has a device field, defined like this:

@DatabaseField(canBeNull = false, foreign = true, columnName =
"device_mac_addr", foreignColumnName = "mac_addr")
private Device device;

I am not instantiating any readings directly. I need to get the readings
from the 'correct' device specified by the Mac address. So, I am relying on

Hi Moritz,

The refresh does not help. Here is my modified code:

List<Device> devices =
(List<Device>)deviceDao.queryF orEq("mac_addr", deviceMacAddr);
if (!devices.isEmpty()) {
Device device = devices.get(0);
deviceDao.refresh(device); // <- REFRESH here

Hi Salil

As far as I know it is necessary to refresh foreign collections after a query.
You could also mark your foreign collection as foreignAutoRefresh=true, but I've never done that so I don't know exactly how that behaves.

Hi Moritz,

My understanding is that refresh is necessary only if I modify the
collection - via some other means than deviceDao.
If I am querying device from database, is the refresh necessary on all
foreign-collections?
Anyway, I will try out your suggestion.

Thanks
Salil

So the docs are pretty good about constructing such queries using the query builder. Have you RTFM?

In your example, you are starting with an in-line and() but there is nothing to the left of it which is throwing the exception. You could move the OR to the front:

Hi Salil

You need to call deviceDao.refresh(yourDevice) in order to populate your foreign collections.

Hi,
I have a table readings which has references devices table.
I define the relation in my device class like this:
@ForeignCollectionField(eager = true, foreignFieldName = "device") # I
tried it with default - lazy first, And it did not work.
ForeignCollection<Reading> readings;
And, in reading class like this:

Hallo!
I want to express a query that looks like this in pseudo SQL:
WHERE COLUMNNAME_TYPE == type AND COLUMNNAME_CODE == code AND
(COLUMNNAME_LANGUAGE == language OR COLUMNNAME_LANGUAGE == null)
To Achive this I am building the following expression using ORM Lite:
queryBuilder.where().and().eq( DisplayableItem.COLUMNNAME_TYP E,
