Make <- c('Toyota','Mitsubishi','Kia','Jaguar') For instance, let us create a new toy table with some cars and the manufacturers by appending two different data frames: # Create toy data framesĬar <- c('Camaro', 'California', 'Mustang', 'Explorer') # List all the tables available in the databaseĪn extremely useful feature when creating tables using RSQLite, is that you can append more data to an existing table using a loop in case that you have several data frames by setting the optional argument append = TRUE inside dbWriteTable(). # Write the mtcars dataset into a table names mtcars_data It should be an R data frame or an object coercible to an R data frame.Īfter that, you can use the function dbListTables() with the SQLite database connection as an argument to check that you have successfully created the table.
value: The data that you want to insert.name: The name you want to use for your table.conn: The connection to your SQLite database.This function can take multiple arguments, but, for now, let's focus on the following: Once you have the database created and your data in proper shape, you can go ahead and create a table inside the database using the dbWriteTable() function. db file has been created on your working directoryĬonn <- dbConnect(RSQLite::SQLite(), "CarsDB.db") # Create a connection to our new database, CarsDB.db # Load the mtcars as an R data frame put the row names as a column, and print the header. If you want to operate with a transient in-memory database however, you can omit the path argument or type ":memory:"). If you are creating a new one, simply give it a name of your choice as I do below. However, this is not usually what you want, so let's create a proper database for the mtcars dataset using the function dbConnect(), which takes the following arguments: RSQLite can create ephemeral in-memory transient SQLite databases just as it happens when you open the SQLite command line. The first step as you may have guessed is to create a database.

Furthermore, I will cover how to use parameterized queries and operations like INSERT or DELETE that do not return tabular results. We will go over the basics of how to perform essential tasks such as sending queries to a SQLite database or creating tables using RSQLite. However, in this tutorial, we will focus on how to use SQLite databases in R using the RSQLite package. So far in DataCamp, you have been exposed to how to operate with SQLite databases from Python (see the SQLite in Python tutorial by Sayak Paul to learn how to manipulate SQLite databases through the sqlite3 package in Python). As mentioned at the end of my previous tutorial, Beginners Guide to SQLite, SQLite databases are most powerful when used along R and Python.
