java - Storing an array - MYSQL -


Given the profile table with details about the user - what is the best way to store in the database? Is allowed .

Each user has a main profile picture - then three optional additional pictures. For possible expansion ability and maintenance, I felt that three alternative images could be stored as an array of some kind (~ and if they do not choose, it can also be a faucet area).

Please advise on any best approach.

Thank you

You should create a separate table to capture the pictures, one Avoid making columns that contain CSV data, because you are used to use CSV every time. Not to mention that updating the column can be a nightmare. 

  Create a table image (image_ id int, picture_fileblob, / * if you use the filename, varchar * / profile_id int / * fk to USER * /)

Then in the profile table shows the main profile picture for the picture through the foreign key. 

  Create a table of users (profile_id int, profile_picture_IDit ​​/ * main picture from fk * /)

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
