filter by query result

Hi,

I am new to pig. First I queried a hive table (x = LOAD 'x' USING 
org.apache.hive.hcatalog.pig.HCatLoader();) and got a single 
record/value. How can I used this single value to filter in another 
query? I hope to get a better performance by filter as soon as possible.
