Display BarGraph With Sqlite Database Column Data

May 8, 2013

I am developing an application in android allowing the user to maintain his weight by providing him diet suggestions. I have done with that part and now, I need to display user weight tracking details using bar graph. I am able to fetch the Weight and Login date column data from the sqlite database to List<String>. I don't understand the way to put these values into a Bar Graph with Date Column data as X-axis and Weight column data as Y-axis.

Android :: Determining Data Type Of Column In SQLite

Jun 23, 2010

I'm working on an Android App where the user has different options for sorting the displayed data that comes from the database. Currently my orderBy string that I pass to Androids query() method looks like this:

"LOWER("+columnName+") ASC"

The problem with this is that if the data type in the column specified by columnName is integer, calling LOWER() on it will cause it to be sorted alphabetically, i.e. based only on the leftmost digit, which of course doesn't make any sense for numeric data. Hence I only want to apply LOWER() if the data type of the column is not integer. What I have in mind is a statement like this:

"CASE WHEN [data type of columnName is integer] THEN "+columnName+" ASC ELSE LOWER("+columName+") ASC END"

The part in the brackets is what I don't know how to do. Does SQLite provide a function to determine a column's data type?

Android :: Put Static Data Into SQLite Database?

Jun 8, 2010

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?

Android :: Data Not Inserting In Sqlite Database

Aug 14, 2010

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.

this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

I am currently working on a java program that inserts excel data into android database(sqlite). when i place the TestDB(sqlilte db) into c:drive it works.

Android : Adding A "column" - Data To A Database Cursor

I am trying to add a "column" to this cursor with the ringer "Title" (since this can change outside my program). I can successfully user RingtoneManager to get the title, but I cannot figure out how to add this "column" to the cursor data for later use. Here is what I have so far: Code...

Android : Create A Sqlite Database That I Can Manually Input Data From My Computer

Nov 30, 2009

I have certain needs that I am having trouble making an app for. I was hoping to be able to create a sqlite database that I can manually input data from my computer and search the data on my droid. I wanted to set up tags or full data search within each sqlite database object so and pull up a listing of best matches for the given search term.

The use for it is that I work on an Air Force Base and my job is very broad. I wanted to custom build an app that I could list all of the information pertaining to my job and be able to search it as I work to find solutions to problems way quicker than we are doing it now.

Is there any such app. I've been trying to create my own and it looks like it would be a mix between notepad and searchable dictionary but not quite.

Android :: Insert Data On Sqlite Database Table From Word Or Excel Document?

May 22, 2010

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

Android : ContentProvider Storage/memory - Data Can Be Stored In File System - In An SQLite Database

Oct 20, 2010

Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?

Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

Android :: SQLite Matching Prefix On Indexed Column

Oct 7, 2009

I have a TEXT column and I want to match all rows where the value has a certain prefix. For example, WHERE mycol LIKE 'myprefix%' However, I noticed in some optimization guidelines that this will not use the index and instead you should do this:WHERE mycol >= 'myprefix' AND mycol < 'myprefiy'Instead of simple A-Z chars, I have a whole variety of UTF-8 chars (think chinese characters).My question is, how to work out the next char in UTF-8? Is it enough to add one to the codepoint,

Android :: Detect If A Table Contains A Column In Droid / Sqlite

Apr 20, 2010

So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function.

Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution.

Android :: Reference Sqlite Db Column To Use In Update Statement

May 8, 2010

I am trying to update a datetime column in an android sqlite db to use international date format (yyyy-mm-dd) instead of the current format (mm/dd/yyyy). I want to use the sqlite date() function to reformat the current value of the column. I thought it would be as simple as the following: update tblename set thedate = date(thedate)

But the above does not work.

How would i write the sql statement to accomplish this?

Android :: ID Column In Contacts Database

Nov 12, 2010

I read that the different entries in different tables are linked via the _ID column in that table. For example a contact might have an _ID = 1 I get via

ContactsContract.Contacts._ID

And now I want to read the phone number of that contact using

CODE:.............

This works fine, but what I would expect is that if the _ID of the contact is 1 that the _ID of the phone number is as well one since they belong together, but they are not equal. So the question is how does Android match these entries?

Android :: Retrieve Single Column Of Last Row In Sqlite / Droid Using ORDER ID Desc Limit 1

Nov 10, 2010

I'm attempting to create a method that will allow me to retrieve a value from the last row of a database, and then insert it into an EditText field. (This is a value that the user will not change all that often, so it would be helpful if when they do set it, it stays set when they come back to it).

My method, based on a similar method I have for getting the total of a specific column, is as such. code...

If I run the program without this statement, it works fine and the value saves to the db. As soon as I try to run it with this, I get a force close. Any suggestions?

Android : Delete Row In Database Table Given One Column Value - Which Is A String

Jul 22, 2010

I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |

I want to delete the row in the table that has Name myName.

// In onCreate
dbHelper = new DBAdapter(this);
dbHelper.open()

// Function in DBAdapter class
public boolean deleteTitleGivenName(String myName)
{return dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=" + myName, null) > 0;}

// Function call in java code
dbHelper.deleteTitleGivenName(myName); // this is where my code fails

dbHelper.close();

Just as a note: myName is for sure in the database. Also, I can not use the ROWID since I am getting myName from a ListView.

I just started programming with Android and I have tried for days to solve this problem.
Is my WHERE clause correct (KEY_NAME + "=" + myName)?
