我一直在使用SQLite for Windows Phone（http://wp7sqlite.codeplex.com/）试图对我做的两个表执行SELECT操作。当我试图这样做时，一旦我打电话给cmd.ExecuteReader()，我得到了“内存不足”异常。用于Windows Phone的C＃SQLite“内存不足”错误
下面的代码WP7/C＃代码：
SqliteConnection conexion = new SqliteConnection("Version=3,uri=file:Database.db");
SqliteCommand sql = conexion.CreateCommand();
sql.CommandText = "SELECT a, b FROM tableA, tableB where tableA.id=tableB.id";
SqliteDataReader res = sql.ExecuteReader();
一旦它执行的ExecuteReader，它显示了一个 “内存溢出异常”。这里的堆栈跟踪：
Message=out of memory
