    Creating SQL Database connection using connection panel in RStudio?

  • @FJ-ow5lm
    @FJ-ow5lm Жыл бұрын

    Do you have the video that connects to MySQL Workbench? I saw the database from MySQL Workbench on the "Connections' pane but when I use 'dbListTables (dbname), it says this: Error in h(simpleError(msg, call)) : error in evaluating the argument 'conn' in selecting a method for function 'dbListTables': object 'spear' not found

    What do you mean "path to database file"?

    The location of the database file on your computer. We’ve got a video on paths that might be useful in figuring out how to write this kzread.info/dash/bejne/ZKeGx6-mhLC_ds4.html

    To connect to SQL Server you’ll need to use the ODBC package. There’s a brief introduction here solutions.posit.co/connections/db/getting-started/connect-to-database/ Hope it helps!

    Getting character(0) when I show tables. Do you know how to fix this? :/

    If this is happening when using dbListTables this probably means you didn’t connect to our database file and so R created an empty one. Check that you’ve downloaded the file linked in the description, that it is in your working directory, and that the name when you run dbConnect() matches the file name exactly (including the file extension)

    Hello thank you for your help. The tables are now showing, but now I have a new error. When I reference a table it says object not found. Do you know why this is happening? The tables were working fine at first but I had to close and reopen R and that is when the problem arose.@@weecology

    @stephensaucedo2746 since you restarted R you’ll need to rerun all of the code to recreate the connection to the database
