[android-developers] Re: Newbie question about Content Provider
Hi, I see the example and I did not find where using insert - Select to put data into database. I assume then that this can not be done, as I searched many examples and have not found anything like. Thanks, for your help. On 20 ene, 06:02, Ricardo Santos ricardo.c.r.san...@gmail.com wrote: Do the notepad tutorial, on the developers page, it will help you a lot.

[android-developers] Re: Newbie question about Content Provider
Are you talking about a content provider or an SQLite database? They aren't equivalent. A content provider *may* use an SQLite database as its database repository, but it doesn't have to, and you can't assume that it does. *If it's a content provider:* You can do an insert followed by a query. Generally, it has to be done in two separate method calls: ContentResolver.insert(); ContentResolver.query(); One row can be inserted per insert(). You can also do a transaction using ContentProviderOperation objects and then ContentResolver.applyBatch(); *If it's an SQLite database:* You can do anything you can do in SQLite itself, using the classes in android.database.SQLite. Remember, though, that in general you *can't* use SQLite classes against a content provider (in general). *In addition:* * * If this doesn't answer your question, you might try to explain your use case rather than simply asking if SQLite operations translate to Android. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi, It's a Content Provider that use SQLite Database. I want pass data of one table to another with Insert-Select sintax and/or check that data not exist in second table. I Found that SQLite permit sintax: Insert into Table(t1, t2) Select tx, ty From Table --To insert select from one table to another OR Insert into Table(t1, t2) Select tx, ty WHERE NOT EXISTS ... --To Check if data exist or not I thought that through the Content Provider could emulate this syntax thanks.
