[Solved] mysql – I dont understand what this means, can anyone explain each line of the script to me? [closed]

It creates a new table “students” in the database if it doesn’t exist already.

  • Each row from ” student_id” to “Reg_date” represent one column in the table.
  • NOT NULL next to a column means you can’t leave it empty when you insert data.
  • “student_id” is a primary key, and is automatically incremented for each entry
  • email has to be unique for every entry.
  • VARCAR is a text entry, int is a number, DATETIME is a date.

I recommend you take some SQL tutorial. There are tons on the internet. This one is great: http://www.w3schools.com/sql/
