Android :: Can Query Inside SQLite Transaction

May 15, 2010

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?

Android :: SQLite Query Throwing Exception

Jul 29, 2010

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

Android :: Choosing Between Requery Or Firing The Query Again In SQLite

Jun 19, 2010

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);

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.

Sqlite Query - Record Is Being Returned If Table Is Empty?

Mar 21, 2012

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);

Android :: Prematurely Stop A Long-running SQLite Query

Sep 26, 2009

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

Android :: SQLite Query And Using Cursor To Deal With Multiple Rows

Jun 24, 2010

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?

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.

Android :: Delete Top Row In SQlITE Database

Aug 2, 2010


public void delete(String id, String name, String phonenumber, String time, String message)
{
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);
}

It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.
