How to Do Queries in RStudio Pro

The Adminer tool was retired on October 12, 2020.

No worries! You can do all your SQL queries on the BioSense Platform by using RStudio Pro. Here are some easy steps to follow and code examples for querying data on the BioSense Platform’s Datamart.

First, log into your RStudio Pro account using your Access & Management Center (AMC) username and password.

Sign in to RStudio


Next, install and load the packages, also called libraries, that you need. These tell RStudio Pro how to connect to the Analytic Datamart. To do this, copy and paste the next two lines into your code.



To run pieces of code, you can highlight the code in your R script and use Ctrl + Enter or use the Run button:

Now you can connect to the Analytic Datamart. This step uses the username and password that you’re already using to connect to RStudio Pro, so there’s no need to re-enter them. You can even store this connection as a variable to reuse.

Copy and paste the line below to store a database connection directly to the BioSense Platform database on the Analytic Datamart.

datamart <- dbConnect(odbc::odbc(), dsn = “BioSense_Platform”)

You can confirm that you’re connected to the datamart by looking at the Environment pane on the right side of your screen.

The last step is to write your query and send it to the database. To do this, copy and paste the code below to R:

              table <- dbGetQuery(datamart, “SELECT * FROM Except_Reasons”))

This example pulls information from the Except Reasons table, but you can insert any query you’d like inside the quotation marks. Once the query is complete, the table of query results will appear in your Environment pane.

And that’s it! The code shown below is enough to get you started reviewing your data in RStudio Pro. After you copy and paste this code into RStudio, delete and retype all double-quotes (“).



datamart <- dbConnect(odbc::odbc(), dsn = “BioSense_Platform”)

table <- dbGetQuery(datamart, “SELECT * FROM Except_Reasons”)

write.csv(table, file =”TableName.csv”, row.names = FALSE)

The write.csv command will write the results to a .csv file that can be exported and opened as an Excel file.

TIP: After you copy and paste this code into RStudio, delete and retype all double-quotes (“).
