RE: How to use sqoop import
There are two ways to import data from sqoop.

Table dump (without select statements)
sqoop import --connect jdbc:mysql://<host>/<database> --username <name>  --password <"*****"> --table <table name> -m 1  --fields-terminated-by <choose any delimiter of your choice>

the -m 1 will give you one input split. If you were to increase that number than you will have to add -split-by <table field>

In case you decide to use select statement in your import:
sqoop import --connect jdbc:mysql://<host>/<database> --username <name> --password <"*****">  --fields-terminated-by ','
--query "select field1,field2...  from <table name> WHERE \$CONDITIONS <conditions> --target-dir <name of directory if you want> --split-by <field1> -m 3

Good luck.

Try this
./sqoop import --connect jdbc:mysql://localhost/my --username user --password 1234 --query 'select * from table where id=5 AND $CONDITIONS' --split-by table.id<http://table.id> --target-dir /dir
you must specify --split-by and --target-dir

Hi All,
  Can any one share some example how to run sqoop "Import results of SQL 'statement'"   ?
 for example:
         sqoop import -connect jdbc:.........  --driver xxxxxxxxxxx
after this if i am specifying  --query "select statement " it is even not recognizing as sqoop  valid statement..
