Hi,
i dont know wether this is write or wrong .but in my way in look up we r having 2 modes cache &noncachemode noncache mode is low performance than the cachemode .bcz look up will maintains the connection with lookup table until comparision is completed.in cache mode lookup table data loaded into memory &dis connected from the lookup table this gives high performance
by using joins we can get the results as of my knowledge
