Jul 29, 2010Im trying to get an object form my SQLite database in my Android application.

Android :: Choosing Between Requery Or Firing The Query Again In SQLite
Jun 19, 2010Have been using a SQLite database, Theres a situation where i have a list which displays all the "name" field data of a table "table1". Now i have a button to insert data in "table1". The list is populated using a simple cursor adapter which is passed a cursor "cursor1" populated with the data. "cursor1" is prepared using the SQLite query - "SELECT * FROM table1". Now the moment i insert data, i need to update the list too.
My question is- will the Adapter sense the database change automatically (i guess not)?
using cursor1.requery() is correct or should i use cursor1 = db.query("table1", null, null, null, null, null, null);

Android :: Prematurely Stop A Long-running SQLite Query
Sep 26, 2009How to programmatically stop a long-running query?
The long-running step is, for example, the first call to Cursor.moveToFirst(). This can sometimes take up to 30 seconds so I would like the user to be able to cancel.
However, how should this be done? I've tried closing the Cursor (in another thread) but all that happens is that the close() call takes as long as moveToFirst() and then terminates with the exception:
java.lang.IllegalStateException: attempt to acquire a reference on a close SQLiteClosable
Android :: SQLite Query And Using Cursor To Deal With Multiple Rows
Jun 24, 2010I've got a query, (I'm using rawQuery())
SELECT * FROM <table>
I'm then storing what it returns using a cursor. From their what I want to do is, start at the first row so.. cursor.moveToFirst() then take each column , column by column and store its particular value in a variable. I then want to move onto the next row and do the same. So I guess my question is How would I get cursor to deal with multiple columns?
Android :: How Cancel/interrupt/break Pending SQLite Query
Aug 11, 2010In my Android application user can fill database with imported data, then perform predefined, complex SQL query. With some data pattern, query will take very long (minutes and more on HTC Hero), while common usage will not exceed 10-15 seconds.
Is there any way to cancel pending SQLite query on Android? Timeout would be as good as well, partial results are not required. I'm performing query within AsyncTask.doInBackground()
I know best way is optimize query or change app logic, but in this case results depends on user knowledge anyway, so I'd like to help those who enter troublesome pattern.
Sqlite Query - Record Is Being Returned If Table Is Empty?
Mar 21, 2012I've a problem with a query in sqlite3.
The query is very simple:
SELECT MAX (INIT_DATE) INIT_DATE FROM TABLE;
When my application execute this query, and the table is empty, a record is returned. I can't understand why a record is being returned if the table is empty. It should return cero results.
I've tried to execute the query in two different ways:
cursor = db.query(true, "TABLE", new String[] {"MAX(INIT_DATE) AS INIT_DATE"}, null, null, null, null, null, null);
cursor = db.rawQuery("SELECT MAX(INIT_DATE) AS INIT_DATE FROM TABLE", null);

View 1 Replies View RelatedAndroid :: 2.2 (Froyo) SQLite Missing IN Clause Functionality?
Sep 29, 2010Recently I updated my Nexus One to Froyo (2.2) and I've noticed some significantly different behavior with SQLite. For example, I had been using a subquery (returning string data) as part of an IN clause, and the subquery portion no longer appears to function correctly. I've attached an example SQL query working with the contacts database below (Direct query shown for illustrative purposes only):
SELECT _id FROM data WHERE display_name IN (SELECT display_name FROM contacts); Up until Android 2.1 this was not a problem. After the update however, this returns an empty record set unless I run the subquery separately, surround each of the resulting values in single quotes and append those values directly into the IN clause. I have noticed this loss of functionality in multiple applications I'm working on, but I should note that it does appear to work when the results would be numeric rather than string based.
Android :: How To Query The MMS Log
Jan 1, 2010In my app I need to query both the SMS and the MMS log to get the history of all incoming and outgoing messages.
This code has worked wonderfully for SMS:
CODE:......
But when I try the following I get completely different results:
COD:....................
The SMS query returns data that includes the message address (phone number), contact name, message subject, message body, etc... The same query for MMS returns a bunch of nulls or numeric value fields that I can't make any sense of. I really need a list of all MMS messages currently on the phone with the phone number or contact ID associated with it, and if the message was an incoming or outgoing message. In the SMS query results I can get the phone number from the address field, and the incoming/outgoing type from the type field but neither of these exist when I query for MMS.
Is there a different content Uri that I need to query for this sort of MMS data?
