creating a table with columns longer than 30 characters

I am trying to run a part of my web application, I have a Model that is using the same DB context as the Identity Model "ApplicationDBContext" using a dbset, A team member went in the database and added two additional columns with data.

So in the Model I went and added the the two columns. I then went and ran the application and got the error, The Model Backing the Db Context has changed, I then went and tried to add a migration for the two added columns, but it is telling me that the Column names must be unique. I know the problem is because the database has the two columns already and using add-migrations is trying to recreate the columns, after using update-database.

Is there a way that I can get this to work. Please follow below link. Column name 'BackupFilenam Column names in each table must be unique. Column name 'BackupFilename' in table 'dbo.

Please look at it. I've only checked the header, didn't load into R. Open in google spreadsheet and you'll come to know how many fields are actually comma separated. Edit whole file with some bash commands then load it into R. Would you mind letting me know what is different between your output and my solution? Yours is obviously more elegant, but being new to R i'd really like to know if my solution does not work, and why that would be.

They look similar in R Studio, yours has some "'s in empty fields, but i'm having trouble seeing anything else. Hi Carlos, your solution is not wrong, its fine. Just don't use a package external if you don't need to. Secondly, the problem was an extra semicolon which might or might not be a part of the headerscrutinizing the file gave me the hint, so we don't have to do all the extra work of renaming columns etc etc. This will produce an error and remove the first line of the file your headersbut the data should load fine.Search everywhere only in this topic.
