Sqoop Import with a query - Where to set $CONDITIONS

[Raj Hadoop]

Hi,
 
I am trying to load data from an Oracle query to HDFS using Sqoop.
 
sqoop import --connect jdbc:oracle:thin:@//gobyuioids:1521/dbgyru --username 
user1 --password pwd--query 'select a.col1,a.col2,b.col1 from sch1.t1 a , 
sch1.t2 b  where $CONDITIONS' --split-by col1 --target-dir tgrdir1
 
 
How to set $CONDITIONS' . Is this a OS variable ? How do I set this ? Please 
advise.
 
Thanks,
Raj
