SQL Server 2005 LEFT JOIN？

Question

我已經在TABLE_1從A到Z 場我也一直在與TABLE_2域B，G和P

我怎麼能找到的所有記錄從TABLE_1 不是：

TABLE_1.B = TABLE_2.B 
TABLE_1.G = TABLE_2.G 
TABLE_1.P = TABLE_2.P 

在SQL Server 2005中？

SELECT t1.* 
    FROM TABLE_1 t1 
    WHERE NOT EXISTS(SELECT 1 
         FROM TABLE_2 t2 
         WHERE t1.B = t2.B 
          AND t1.G = t2.G 
          AND t1.P = t2.P)
