DatabaseConnector is part of HADES.

Introduction

This R package provides function for connecting to various DBMSs. Together with the SqlRender package, the main goal of DatabaseConnector is to provide a uniform interface across database platforms: the same code should run and produce equivalent results, regardless of the database back end.

Features

Examples

connectionDetails <- createConnectionDetails(dbms="postgresql", 
                                             server="localhost",
                                             user="root",
                                             password="blah",
                                             schema="cdm_v4")
conn <- connect(connectionDetails)
querySql(conn,"SELECT COUNT(*) FROM person")
disconnect(conn)
