Maybe its a easy question but i cant figure out how to do tables with multiple columns and rows.. Order data in this table will be get via wcf service and next present in table. In this table i need of course scrolling and filtering. Every row will link in to details about order.

Thanks for help.

dataAdapter.setFilterQueryProvider() can be used for older versions. From android3.0 this use has been deprecated. U have to cursorloader or u can copy the database content to a arraylist.
Best practices to query SQLite database in ListFragment with CursorLoader?
I am working on quiz application and need to store 3000 questions with 5 options and correct answer. So how to store bulk records into my sqlite database in android. How can I do that. I had searched in google but I didnt find the exact solution for that. Any help regarding this will be thankful...
Not sure I completely understand your question, but insertion of rows in SQLite is efficient if you make use of transactions and prepared statements.
This question already has answers here:
adding a column to SQLite table in Android?
(3 answers)
Closed 8 years ago.
Ive asked this question several times and yet to get a COMPLETE answer... How to you implement the ALTER TABLE statement to add a column to a database. Can someone PLEASE give me an example?
Please read the SQLite ALTER TABLE reference, and this Android SQLite article:
database.execSQL("ALTER TABLE " + your_table_name + " ADD COLUMN " + new_col_name + " int");
ALTER TABLE db_name.mytable ADD COLUMN column_name VARCHAR(30)
That's for SQLite. Other databases may allow you to specify where the column gets put, but with SQLite it's appended to the end.
EDIT:I thought about this some more. In your question you asked for a complete answer. And someone identified that you asked essentially the same question just 5 hours before asking this one. Considering that none of the responses in that previous thread were what you were looking for (despite some of them offering complete SQL examples), it strikes me that a complete answer must include something more than the SQL and a few links to web tutorials.
In an effort to be thorough and complete, let me suggest that you consider the following books: Using SQLite (O'Reilly), and Learning Android (O'Reilly). In fact, the latter has a chapter (chapter 9) devoted to the Android database environment, meaning Android's implementation of SQLite.
People who have a lot of experience with databases, with programming, and with diverse operating systems often can get by with web manuals and a few tips on sites such as StackOverflow. But for the rest of us (myself included), when I really want to learn a topic that I consider important to me, I immerse myself in a couple of good books along the way.
I hope that you, or someone else who may be just getting started with such topics, find this advice helpful.
I've just encountered this and tried over and over and got the exception described here about column not exists, despite the alter table statement didn't throw any exception.
After two hours of trying, setting up a file backup storage, and whatever seemed viable here, I realized that I didn't include the new column in the "select query", but still tried to extract the data from the cursor, hence the column does not exist exception.
Can someone help in writing a Custom Content Provider for Multiple tables. I can write for a single table but for multiple table I did not find any good example.
A near duplicate of an existing answer. Compare this question and answer, discussing use of LEFT JOIN inside your ContentProvider.
Note that, all in all, the expected use of ContentProviders is to use single tables for each path in your Content URI. It's still seen as something out of the norm to use join or index multiple tables in one call. Not to say it's bad, just that there aren't many people thinking in those terms.
