These are the tips for you if you have lost your way.

• getting something error
  ask me “what’s happening”, “open error”, and so on. I may be able to help you if I have some information about it, or if I don’t. :p
  
• Tidy up your screen
  Just order me ‘refresh’, ‘clean up,’ and so on. I will show you my cleaning magic.
  
• There are similar column names.
  Please specify if you want to select only one.
  
• Errors happen when uploading a file.e
  Your header name causes most cases, as it does not conform to the selected database’s rule for column names. Recheck it.
  
• How many data numbers can be uploaded at once?
  That’s a good question, but I don’t have the answer. May 100,000, may 1,000,000, who knows? Ask your machine.
  
• How can I see ‘your’ env?
  Oh, my, do you want to see my privacy? Well, ok, I trust you. Enter Julia prompt, “julia>”, with kicking ‘repl’, then type ‘]’ to enter ‘pkg>’, then type ‘st’, “julia>st”. You will see some library versions that are constructed for me.
  
• ‘who am i?’
  shows your current profile.
  
• primary key in a table
  ‘jt_id’ column is the primary key in each table. I add this column to each table by creating it when the CSV file is uploaded, no matter whether you set your own primary key in the file. Then this primary key is to be the reserved parameter in ‘ju*’ and ‘jd*’ APIs.
  
• If I uploaded the same CSV file again?
  Append the data to the already existing table. I mean it will be duplicated if the same data is uploaded. It will be as you expect if the data were new.
  
• Wanna test your WebApi?
  Of course, you can do it on me with ‘test api’, but I know you wanna do it on me sometimes.
  Tatta laan, there is a new test page for it. You can access to this page on your site ‘….jetelina/jetelina_apitest.html’. e.g http://localhost:8000/jetelina/jetelina_apitest.html,
  the behavior in this page is as same as act on me, but I guess I’m familiar with you.
