Installing database drivers¶
Before being able to create SQL-based datasets, you need to install the proper JDBC drivers for the database that you intend to connect to.
Additionally, PostgreSQL script recipe support requires the command-line psql client to be installed. See PostgreSQL support.
Download the driver¶
Data Science Studio comes with bundled drivers for :
- PostgreSQL 9
- EMC Greenplum
- Amazon Redshift
- SQlite
Drivers for other databases must be downloaded from your database vendor.
| Database | Website | Download link |
|---|---|---|
| MySQL | http://dev.mysql.com/downloads/connector/j/ | http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.27.zip |
| HP Vertica | https://my.vertica.com/download-community-edition/ | Requires a My Vertica account |
| Oracle | http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html | |
| SQL Server | https://msdn.microsoft.com/en-us/data/aa937724.aspx | https://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774 |
Stop Data Science Studio¶
In this page, DATA_DIR refers to the data directory where you installed Data Science Studio.
Note
On Mac OS X, the DATA_DIR is always: $HOME/Library/DataScienceStudio/dss_home
Installation of JDBC drivers must be done while Data Science Studio is stopped.
DATA_DIR/bin/dss stop
Copy the driver¶
Copy the driver’s JAR file (and its dependencies, if any) to the DATA_DIR/lib/jdbc folder
Restart Data Science Studio¶
DATA_DIR/bin/dss start
PostgreSQL support¶
Data Science Studio supports datasets stored in PostgreSQL 9.
Warning
PostgreSQL version 8 is not supported.
PostgreSQL script recipe support additionally requires the command-line psql client to be available in the search PATH of the Studio Linux account.
You should install a command-line client compatible with your version of the server. Depending on your Linux distribution, the appropriate client may be available in a standard OS package named “postgresql-client” (Debian / Ubuntu) or “postgresql” (RedHat / CentOS 7). If that is not the case, you can install the correct client for your server and OS by configuring an extra package repository as described at http://www.postgresql.org/download/ .
