List the database tables
After you've successfully connected to a remote MySQL database, the next step is to see what tables the database contains. You can do this with the dbListTables()
function. As you might remember from the video, this function requires the connection object as an input, and outputs a character vector with the table names.
This is a part of the course
“Intermediate Importing Data in R”
Exercise instructions

tables
, that contains the tables in the tweater database. You can connect to this database through thecon
