Android中的sqlite事务操作

                SQLiteDatabase db = this.getWritableDatabase();
		db.beginTransaction();
		db.delete(this.DAILY_EXAMINE, "1=1", null);
		db.delete(this.ENTERPRISE_EXAMINE, "1=1", null);
		db.delete(this.LAW_ENFOREMENT, "1=1", null);
		db.delete(this.EVENT_EXAMINE, "1=1", null);
		db.delete(this.LOCUS_OF_POINT, "1=1", null);
		
		db.setTransactionSuccessful();
		db.endTransaction();

使用事务进行数据操作可以大大提高数据的操作效率
