[android-developers] Re: Help! How to query a database?

I like the raw query:

String sql = "SELECT * FROM tableName";

Cursor c = mDb.rawQuery(sql, null);

I can see my sql statements better than the helper function "query"

Also if you use eclipse and run the debugger, you can see the sql
built from the query function
inside your cursor variable
