Thanks for quick answers guys!
It works very well with getCount(). Do you have any suggestions about
the query thou? Because it still returns 0 on get count when I try to
look for the already existing entry.

Re: [android-developers] Re: SQL query
Your query looks ok to me.
Check how you insert data, and make sure that the value that's stored in
the database is what you expect.
Oh, and before you call recentC.getLong(recentC.getColumnIndexOrThrow,
make sure you've moved the cursor to the first row.

Can anyone tell me how to specify distict clause in query provided by android content provider? You can't. You cannot assume that a ContentProvider uses a SQL-compliant database for its storage. It might use flat files. It might use a db4o. It might use a cache for data retrieved off of a Web service. Hence, the syntax for the selection and selectionArgs is up to the provider. However, even for SQLite-backed providers, selection is simply the WHERE clause without the keyword WHERE, so you do not have access to the spot to put the DISTINCT keyword. If I opt for writting rawQuery how to specify projection and URI ? There is no rawQuery() option for ContentProvider, AFAIK. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
