Android :: How Cancel/interrupt/break Pending SQLite Query
Aug 11, 2010
In 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.

I have a query that pulls everything from a database into a list view.
code:..........
I want only the records where the field KEY_HOMEID matches a variable called journalId which should be a numeric string.
I would also like to know how to bring the variable into my DatabaseAdapter... would ((resource)this.getApplication()).getjournalId()) work? resource is a class that extends application.

I am trying to write a select query from one single table in SQLite DB in my app where data exists.
This is the SQL.table has these columns - id(INTEGER), start_time(INTEGER), category(TEXT)
select category from tuuserid_pref where id = (select max(id) from tuuserid_pref
where start_time < '1242'); by the way I want to bind the value shown in 1242 which I have in an Integer variable.
I have written selects and inserts and updates without binding parameters and they work using db.execSQL and db.rawQuery functions but just cannot figure the binding parameters out.

I'm using the SQLite3 database system in the Android library. I need to execute a query during a transaction to see if there is a similar entry already there. If there is, I have to perform some other logic and adjustments before I add a new row. Can I execute a query within a transaction and get the result back immediately?

Is there any way out to achieve "SELECT * FROM tblname WHERE name LIKE '%[0-9]%' ". i know we can't do this with sqlite~ but how to deal with such query task with sqlite? i tried to use REGEXP ~but unluckily it is not pre-defined~ so i tried to define it by myself...but even i couldn't find a way in android to create a UserDefinedFunction...

Im trying to get an object form my SQLite database in my Android application. I know that the contact is in the database because when I add it and try finding by ID, it returns the object. When I try finding by first and last name, though, it throws an exception and Im left with a null reference.
Here is the query:
CODE:..........
Ive also tried to find just by first name and just by last name. Same result as above.
The exception is an SQLite exception
no such column: aurelius: , while compiling: SELECT _id, last_name, first_name,
email_address, organization_name, label, label_position FROM contacts WHERE
first_name=marcus AND last_name=aurelius
And also happens when trying to select just first or last name
no such column: marcus: , while compiling: SELECT _id, last_name, first_name,
email_address, organization_name, label, label_position FROM contacts WHERE
first_name=marcus

Have 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);

I have this query which does work fine in MySQL
CODE:............
Distance is in Kilometers, the input is lat=12.345 and lon=67.89
The SQLite is 3, and I can't run custom functions with it as it's on Android. I also don't have acos() etc... as that is not part of the standard SQLite.
How would be the above query in SQLite?

How 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

I'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?

I'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);

Since I installed 2.1 (betas and now official) the notifications mute any music or podcast I am listening to through the headphone jack. If I'm using the internal speaker, the notification plays, but the music or podcast is still audible. Is everyone else having this happen, and if so, is there a workaround?

I've found differences in the behaviour of notifications on different ROMs, notably in the stock Jellybean ROM for my i9100 a notification will:
1. Mute all other sounds
2. Play the notification sound
3. Unmute other sounds
Whereas when I have AOKP installed the sounds both play at once, as in no muting occurs and the sound is overlayed.

I just got a new 2014 Chevy Sonic and I have paired my Huawei H881C to the car stereo. Once for "Phone" and once for "Music". Right now I can play the car radio music OR press a button on the car stereo that says "Media" and select "Bluetooth" which turns the car radio music off and lets the GPS voice directions come through the car stereo speakers but no music. I can't have both, the car radio music and GPS voice directions at the same time. Seems like the music volume should mute while the GPS directions are given then return to the previous volume and continue playing the music I had going. Instead it's "either or". ?

Does anyone know how to break a market link.
I have a couple of apps that have changed from free to trial versions and would like to have them not show up as needing an update. I am rooted, and have SQLite and Root Explorer but I cannot find where that bit of info is stored. If someone could point me in the right direction, or if you know of an app to do this, that would be great. I know TB can backup/restore the market link so it should be possible to break it somehow.
