How to store array in one column in Sqlite3?

Question

Is there any way to store an array of integers in one column of table? I want o/p like this:

ident | value

Sorry to Necro, just came across the problem myself and found a solution.

As stated already SQLite has no support for arrays, so you can't store them as such. Try this, I had the same problem;

Instead of storing array elements individually, you can store them as a large string and use a string function or Regular expression to parse them back into their types. An C# example

int[] myArray = new int[] {8,4,345,378,34456,7};

string Arraystring = myArray[0].ToString();

for(int i = 1; i < myArray.Length; i++) { 
Arraystring += "," + myArray[i].ToString();

}

This will turn the array into a single string, now we take the string and insert it into the table as a string, when you read the string use this code to get the array back. Another C# example

string value; //assign this via Reader
string[] tokens = values.Split(',');

int[] myItems = Array.ConvertAll(tokens, int.Parse);

this will only work with single dimensional arrays, multi-dimensional can get tricky when it comes to parsing the strings.
