来自http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html：

public Cursor rawQuery (String sql, String[] selectionArgs)

public Cursor rawQuery（String sql，String [] selectionArgs）

Runs the provided SQL and returns a Cursor over the result set. Returns a Cursor object, which is positioned before the first entry

运行提供的SQL并在结果集上返回Cursor。返回一个Cursor对象，该对象位于第一个条目之前

compared to:

相比：

public void execSQL (String sql, Object[] bindArgs)

public void execSQL（String sql，Object [] bindArgs）

Execute a single SQL statement that is not a query. For example, CREATE TABLE, DELETE, INSERT, etc.

执行不是查询的单个SQL语句。例如，CREATE TABLE，DELETE，INSERT等。

In other words, SQL queries which return a table are to be run with rawQuery, and those that do not return tables are to be run with execSQL.

换句话说，返回表的SQL查询将使用rawQuery运行，而不返回表的SQL查询将使用execSQL运行。
