Anyone know how to read / query data from PostgreSQL DB ? Thanks before.

The only supported data sources in the product are forum.appian.com/.../Configuring_Relational_Databases.html. I don't think you can guarantee an integration with an unsupported RDBMS will work unless you write your own custom plug-in to support it.

Hi Eduardo,
In here: forum.appian.com/.../Query_Database_Smart_Service.html , we got an information that others database that are not listed there are also supported for use with the Query Database Smart Service, as long as the database provides a JDBC compliant database driver.

Is it possible to adding another database in list of custom data source?

Oh I thought you were planning to use them with query rules. You might give it a go if the documentation states that, but keep in mind that only applies to on-premise.

Search online for JDBC connections with JBoss and Postgres to learn more about how you can add it to appian-ds.xml

Ok Eduardo, thank you. Will try to explore this first.

A start point would be the comments on developer.jboss.org/.../JBossAS7-DatasourceConfigurationForPostgresql
