I have a query that selects rows in a ListView without having a limit. But now that i have implemented a SharedPreferences that the user can select how much rows will be displayed in the ListView, my SQLite query doesnt work. Im passing the argument this way:
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:
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 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.
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.
In android, How can I query the name of the MMS sender and text of the MMS from MMS database? For SMS, there are these 2 columns for that: Sms.PERSON_ID and Sms.Body. But what is the equivalent columns in MMS Table?
Can anybody suggest what functionality to provide in a query utility class/classes? The idea is to provide a database utility package for android developers. I just wanna do it for android community and of course for my learning.:-)
I'm trying to deploy an application with an existing SQLite database.I've been reading though the examples that are posted but they are always missing some part of the class. I feel like I'm trying to bake muffins but no one told me to use baking powder.Can someone post a full database helper class for depoying an SQLite database on Android? Edit : Delete old code because it doesn't work.
I'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?
In my android app i need to get 50,000 database entry(text) and compare them with a value when the activity started(in onCreate()).I am doing this with the simplest way : i get the whole table from db to a cursor.However this way is too laggy.Are there any other way to do it more effective?The app is "scrabble solver" that is why i am not using WHERE close in my query (Take the whole data annd compare it with combination of the input letters).At first i was using a big table which contains whole possible words.Now i am using 26 tables.This reduced the lag and i am making database call on a thread that solved a lot problems too.It is still little bit laggy but much better.
I'm new to Android, I just finished the Notepad Tutorials, where we can create SQLite Databases to save notes. So I wanted to know if it was possible to "import" my own SQLite database (not created with my App but with a 3rd-party software) to my project, and if the answer is yes, where should I save my SQLite databse and how can I have access to it.
I'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things. On a PC I would just make an XML but with android I'm not sure. Can I make an XML and "unpack" it when the user launch the application for the first time or should I do something else?
