Sqoop Where

You can place restrictions on data imported by using "where" clause. Let's import cityByCountry table where state ( 6th column is restricted to "Alaska").

The Sqoop statement is written below

sqoop import \ --connect "jdbc:mysql://localhost/training" \ --username training -P \ --table cityByCountry \ --target-dir /user/where_clause \ --where "state = 'Alaska'" \ -m 1

Output is shown below

Let's list all databases present on a mysql server using a "list-databases" tool.

Note : for more information on list-databases, type "$ sqoop help list-databases".

$ sqoop list-databases --connect "jdbc:mysql://localhost" --username cloudera --password cloudera

Similarly for listing tables

$ sqoop list-tables --connect "jdbc:mysql://localhost/training" --username cloudera -P
