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 using the following code for my APP search
Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(Uri.parse("market://search?q=pname:QueryString")); startActivity(intent);
Is it possible to change the QueryString once App is downloaded?

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?

View 2 Replies View RelatedIm 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:

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,

first_name=marcus AND last_name=aurelius

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?
I have a problem programming with android SDK 1.6. I'm doing the same things of the "notepad exaple" but the programm crash when i try some query. If i try to do a query directly in to the DatabaseHelper create() metod it goes, but out of this function it doesn't.
This is the source:

Am I going wrong anywhere here ? because this is giving runtime error. application stopped unexpectedly.

I'm trying to integrate google search widget, but met a problem when retrieving keywords from google search widget. It only has problem in the following scenario:
1. Launch my application, and click back. 2. Enter keyword in google search widget, i..e 'a', and launch it. Everything works fine. 3. Press Home. 4. Enter keyword in google search widget, i..e 'b', and launch it. But my application still got 'a' from getIntent() method.
The problem seems to be caused by activity life cycle. For step.4, only onRestart -> onStart -> onResume -> ... is called so that I can't get the launching intent from google search widget. The bug goes away if I finish my application in onStop method. (But it will cause problem for landscape<-> portraint switch since onStop is also invoked when switching screen). Is there any way to get the query string from google search widget for this scenario? Or did I miss any setting in AndroidManifest.xml?
i want to run a delete query with limitation . I've tried to many queries but they didn't work . For know , I just want to remove all the rows and I write this code "

The emulator runs perfectly without any error . right now , I have 32 rows with cat = 21 . solve this problem ?
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?
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'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);
I want to insert a String value call temp but I don't seems to get it working for the INSERT INTO statement. Anything wrong with the code? This is the initialization to create table and insert some default values into the table if the database doesn't exist. Code...
View 4 Replies View RelatedI'm working on a android application that will display Strings to the user, and the user then has the option to add one to a favorite list. I have searched and searched and cannot find the proper way of doing this. I did get one open source project, everything worked until the user removed a favorite. The database would clear the row of data, but when a new row is added, it would behave as if the deleted row still had data, leaving blanks in the favorite list.
This is my insert method
public long insertString(String newString)
ContentValues newStringValue = new ContentValues();
newStringValue.put(KEY_STRING, newString);
return db.insert(DATABASE_TABLE, null, newStringValue);
The long returned will always increment even if i use the remove method:
public boolean removeString(long _rowIndex)
return db.delete(DATABASE_TABLE, KEY_ID + "=" + _rowIndex, null) > 0;
If I try to remove the third index, and the user removed a question at the third index, the method returns false, is there a way to completely remove all rows with no data?
I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:
INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);
but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?
can we use truncate query in android database? otherwise can we performing truncate operation using our java code?

View 4 Replies View RelatedIn Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.
