node-red-contrib-postgrestor

Node-red-contrib-postgrestor :space_invader: is a Node-RED node allowing basic access to Postgres :elephant: database.

Node-red-contrib-postgrestor sets up a console to execute queries against the configured database.

msg.payload will contain the result object of the query. It has the following properties:

  • command: The sql command that was executed (e.g. "SELECT", "UPDATE", etc.)
  • rowCount: The number of rows affected by the SQL statement
  • oid: The oid returned
  • rows: An array of rows

Postgres implements a template engine allowing parameterized queries:

/* INTEGER id COLUMN */
SELECT * FROM table WHERE id = {{ msg.id }}

/* VARCHAR id COLUMN */
SELECT * FROM table WHERE id = '{{ msg.id }}'
