I'm trying to populate my tables. Yesterday I was able to populate one table. I went to "edit top 200 row" and then I went to my excel file, copied the information, and pasted it onto the database. I realized I wanted to add more data, so I deleted the data I had and now I just keep getting an error message whenever I try to populate the table again:
How do I get rid of this message?
I'm using sql server 2014.
