Analyze Dynamics NAV Data in R via JDBC

Access Dynamics NAV data with pure R script and standard SQL on any machine where R and Java can be installed. You can use the CData JDBC Driver for Dynamics NAV and the RJDBC package to work with remote Dynamics NAV data in R. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular, open-source R language. This article shows how to use the driver to execute SQL queries to Dynamics NAV and visualize Dynamics NAV data by calling standard R functions.

Install R

You can match the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running open R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open 3.2.3, which is preconfigured to install packages from the Jan. 1, 2016 snapshot of the CRAN repository. This snapshot ensures reproducibility.

Load the RJDBC Package

To use the driver, download the RJDBC package. After installing the RJDBC package, the following line loads the package:

library(RJDBC)

Connect to Dynamics NAV as a JDBC Data Source

You will need the following information to connect to Dynamics NAV as a JDBC data source:

• Driver Class: Set this to cdata.jdbc.dynamicsnav.DynamicsNAVDriver
• Classpath: Set this to the location of the driver JAR. By default this is the lib subfolder of the installation folder.

The DBI functions, such as dbConnect and dbSendQuery, provide a unified interface for writing data access code in R. Use the following line to initialize a DBI driver that can make JDBC requests to the CData JDBC Driver for Dynamics NAV:

driver <- JDBC(driverClass = "cdata.jdbc.dynamicsnav.DynamicsNAVDriver", classPath = "MyInstallationDir\lib\cdata.jdbc.dynamicsnav.jar", identifier.quote = "'") 

You can now use DBI functions to connect to Dynamics NAV and execute SQL queries. Initialize the JDBC connection with the dbConnect function.

Before you can connect, OData Services will need to be enabled on the server. Once OData Services are enabled, you will be able to query any Services that are published on the server.

The User and Password properties, under the Authentication section, must be set to valid Dynamics NAV user credentials. In addition, specify a URL to a valid Dynamics NAV server organization root and a ServerInstance. If there is not a Service Default Company for the server, set the Company as well.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Dynamics NAV JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.dynamicsnav.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a sample dbConnect call, including a typical JDBC connection string:

conn <- dbConnect(driver,"jdbc:dynamicsnav:http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;")

Schema Discovery

The driver models Dynamics NAV APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:

dbListTables(conn)

Execute SQL Queries

You can use the dbGetQuery function to execute any SQL query supported by the Dynamics NAV API:

customer <- dbGetQuery(conn,"SELECT Name, Prices_Including_VAT FROM Customer")

You can view the results in a data viewer window with the following command:

View(customer)

Plot Dynamics NAV Data

You can now analyze Dynamics NAV data with any of the data visualization packages available in the CRAN repository. You can create simple bar plots with the built-in bar plot function:

par(las=2,ps=10,mar=c(5,15,4,2))
barplot(customer$Prices_Including_VAT, main="Dynamics NAV Customer", names.arg = customer$Name, horiz=TRUE)
