I am trying to find out the best way to do a simple table join on my two tables using a sqlite database in an android application. Is the simplest way to use CursorJoiner or is there any easier way?

View 1 Replies View RelatedI have a ArrayList
ArrayList<String> values=new ArrayList<String>();
values.add("s");
values.add("n");

In this i want to remove repeated value.
I have array list of geopoints
List<GeoPoint> geoPointsArray = new ArrayList<GeoPoint>();
I want to put geoPointsArray array in to SQLite database and then fetch the data back as an array.
Now I use ContentValues for insert into array as:
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_TIME, time);
db.insert(tableName, null, initialValues);
My web service is returning quite a bit of data, so i'm storing it in an arraylist and returning that to my application. I don't know whether or not this is the preferred method or not. When the arraylist is returned and displayed in my application, it also displays the arraylists "anyType" section. I'm new to this whole process so i'm sure i'm missing something somewhere or going about this incorrectly. Can anyone point me in the right direction please?
View 2 Replies View RelatedI was so excited when LPP updated a while back and added the option for additional rows and columns....but it didn't resize things the way I wanted. I had hoped it would be tweeked and it seems better now but I'm still having an issue with Beautiful Widgets on the full size Home Weather. It doesn't fit the entire information completely with temp, etc. without pulling it down to fit across about 3 rows...which makes it look huge
Anyone else have this problem? Or should I just accept it and use the smaller Beautiful Home widget? And is there a way to resize the text size under the description of the app? I can remove it and kind of like it without it...but was curious if I'm missing something

I'm trying to use Android SDK's SQLiteQueryBuilder to join two tables, let's call them t1 and t2, and query that table based on an attribute from each table, say t1.att1 and t2.att2, equaling a certain value. I'm a little confused on the syntax when it comes to the selection.
View 1 Replies View RelatedI need to display a single list, ordered by date which contains different types of data, images, video and whatnot.
I guess you could have one separate table for each type and the use something like FULL OUTER JOIN (simulated as sqlite doesn't support it) and sort on date. But this would be complicated because I still need to have unique IDs across all tables.
Maybe having a master list which has ID and date, and then JOIN in the types tables? But how bad is the performance of this using sqlite? I really like to avoid having a super table which contains columns all the combined types could ever need.
I want to operate on multiple tables. I searched a lot but everywhere I could find is single table with one content provider.
How can I use multiple tables under one content provider? How can I get result from two/three tables ?
Can I provide my own SQL select query from multiple tables in ContentProvider?
Can anybody give me any example or link where I can get idea?

Does anyone of you know how to create dynamic Tablelayouts? On my Emulator Android just shows nothing.
View 2 Replies View RelatedOn an Android layout, I'd like to have a set of rows, each with two TextViews. The leftmost column of TextViews should be right-aligned, just left of an imaginary centerline down the screen. The rightmost column should be left-aligned.
Examples of this can be seen at http://stuff.greenberg.org/ScopeCalc.htm
What's the best layout to use?

View 1 Replies View RelatedI have this database file under the usual databases folder and a bunch of tables inside it. Please note that I don't want to retrieve under the command line. I know I can use the ".tables" command. I want to retrieve a list of all tables in it, using code, so that I can execute some specific algorithms on each of them. Also, I didn't find any questions with this problem on Android, so please forgive me if there is any. I was wondering if there is any function I can use under Databases, but I didn't find any either.
View 1 Replies View RelatedHow to retrieve data from two tables via the ContentProvider way? I.E. the database of Calendar application, include many tables including Events and Deleted, and some others. I want to retrive records in Events table, whose _sync_id field is also in Deleted table. Usually, we write a SQL sentence like: select (all fields in Events) from Events as e, Deleted as d where e._sync_id = d._sync_id or select * rom Events as e where e._sync_id in select _sync_id from Deleted etc. But, how can I accomplish it in the ContentProvider way? I saw ContentProvider.query take a Uri as the first parameter, but pity that I don't know how to build one that could fulfill my purpose.
View 2 Replies View RelatedAnyone working with big sqlite tables and trying to match rows using patterns (for example for autocomplete purposes) ? recently i played with LIKE statement and it seems it will never use table index (if any), you have to use GLOB instead. but....... the weird thing is that you cannot use selectionParams in your query: you have to specify your pattern in selection like:
CODE:........
My words table has two TEXT columns: 'key' and 'value' and index on 'key'
For example: i have table with ~28000 rows and when using selectionParams my query took 1500 ms and without selectionParams 20 ms does it have anything to do with android or its sqlite weird feature?
I have about twenty pages of information that is stored in tables that needs to be stored in my Android application. Each column is a designated stop on a bus route and the column is filled with times that the bus will be at the stop. There is also certain information that needs to be associated with some times, such as if the bus is handicap accessible at a certain time.
Here is an example of one of the tables: Bus Times
I have thought about using a SQL lite as that seems as though it would be able to store these tables quite easily; but when I think of using SQL I think of dynamic data storage and this shouldn't be changing more than once a year.
Is SQL appropriate for this application? Is there a better way to do this?
I have set a content provider, for some reason I am able to to delete a row this way:
getContentResolver().delete(myUri, "_id=" + "3", null);
but i am not able to delete a row that way:
getContentResolver().delete(myUri, "NAME=" + "chris", null);
getting this error:
02-15 15:48:08.197: ERROR/AndroidRuntime(3043): android.database.sqlite.SQLiteException: no such column: chris: , while compiling: DELETE FROM User WHERE NAME=chris
I have checked my database file, and it is there.. but for some reason i can delete columns from my database only by the _id column, how can i fix this?
error:

I've got a question about updating an app after release. If I have a database that contains 10 columns and I add a feature that requires an 11th column after the app has been released, where would I put the sql code to add the new column so that when they install the app it keeps their current data, but adds that 11th column? Is that even possible or would I need to create another table that references the first with a foreign key?

I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste.
