Load data from PostgreSQL

This section describes how to connect PostgreSQL with Exasol and then load data.

To view details about data type mappings or to migrate data, see the PostgreSQL to Exasol migration script in our GitHub repository.

Add JDBC Driver

To add the JDBC driver, create a configuration file called settings.cfg with the following settings:

DRIVERNAME=PostgreSQL
PREFIX=jdbc:postgresql:
FETCHSIZE=100000
INSERTSIZE=-1

Follow the procedure described in Add JDBC Driver to upload the settings.cfg configuration and JDBC driver files to Exasol.

Run statement

Run the following statement to create a connection.

CREATE OR REPLACE CONNECTION JDBC_POSTGRESQL
 TO 'jdbc:postgresql://192.168.99.100:5432/my_db'
 USER 'username'
 IDENTIFIED BY 'Exasoltest';

Run the following statement to test the connection.

 SELECT * FROM 
 (IMPORT FROM JDBC AT JDBC_POSTGRESQL
   STATEMENT 'select ''Connection works'' '
  );

Load data

You can use the IMPORT statement to load data using the connection you created above. IMPORT supports loading data from a table or a SQL statement.
