Accessing the dbase

On the database server, the entire Harvard Dataverse for Patent Data is downloaded in directory

 /bulk/patent

The files have been processed to be used for the create table scripts I have created to load the Harvard Dataverse database into our own psql database.

These preprocessed files are available under

/bulk/patent/preprocessed

The database I have created for the Patent Data from 1975-2010 is called patent data. After logging in to researcher@128.42.44.181, you can get access to the database by

psql patentdata

You can see a list of the tables inside the patent database by

patentdata=# \dt
           List of relations
Schema |   Name    | Type  |   Owner    
--------+-----------+-------+------------
public | assignees | table | researcher
public | citations | table | researcher
public | classes   | table | researcher
public | inventors | table | researcher
public | invpat    | table | researcher
public | lawyers   | table | researcher
public | patdesc   | table | researcher
public | patents   | table | researcher
public | scirefs   | table | researcher
public | usreldocs | table | researcher
(10 rows)

You can select from the database, for example, by

patentdata=# SELECT * FROM CLASSES WHERE patent='03930270';
 patent  | prim | class | subclass 
----------+------+-------+----------
03930270 |    1 | 360   | 130.24
03930270 |    0 | 360   | 84
03930270 |    0 | 360   | 271.8
03930270 |    0 | G9B   | 15.08
(4 rows)

Or, do a join:

patentdata=# SELECT * FROM inventors AS i, classes AS c WHERE i.Patent=c.Patent AND i.Patent='03930270';

 patent  | firstname | lastname | street |   city    | state | country | zipcode | nationality | invseq |  patent  | prim | class | subclass

The schema I used for this database is documented at the bottom of this page.

And this is also saved as a .sql script under

/bulk/Software/Database\ Scripts/createtables.sql

A corresponding Drop table scripts is also available at

/bulk/Software/Database\ Scripts/droptables.sql

Converting DataTypes

Method 1: Explicit recast

CAST function

Method 2: implicit recast

SELECT varname::type

Method 3: through a language

CREATE OR REPLACE FUNCTION chartoint (text) RETURNS int AS $$
    if ($_[0]) {
    	return $_[0];
    }
    return undef;
$$ LANGUAGE plperl;

The scripts for cleaning up the tables are available under /Database\ Scripts/cleaning\ db.sql
