Answer 1

SQLite provide functions for this purpose, e.g. to get substring substr('your string', start_position, end_position), to get position of a specific character in a string instr('22:string', ':'), and to get length of a string length('string'). Now let see the following examples:

select substr('22:khan', x, y);
returns a string starting at x and ends with y;
select substr('22:khan', 0, instr('22:khan',':'));
returns: 22 
select substr('22:khan', instr('22:khan',':')+1, length('22:khan'));
returns: khan
select substr('22:khan',instr('22:khan',':'), length('22:khan'));
returns: :khan
select substr('Noor,Khan', 0, instr('Noor,Khan', ','));
returns: Noor
select substr('Noor,Khan', instr('Noor,Khan', ',')+1, length('Noor,Khan'));
returns: Khan
