create procedure to insert data in database., call the proc from your code with appropriete params.

SQL

create proc myInsertProc
Begin
  
  //first get the matching records, with the query ilke
  
  select count(1) into variable1 from table1 where column1 like 'Comp%';

   if variable1 > 0
      variable2 = 'Comp' + variable1;
   else  
      variable2 = 'Comp';
   end if;
   
   insert into table1 (column1) values (variable2);
End

I also agree with Mehdi Gholam, this problem is very ordinary, you can convert each record (in constant) to string and adding it a counter (in loop) for generate its!

I wrote this recursive function and you can use it for generate:

C#

string f(string ConstStr, int from, int to)
{
    if (to == from)
        return ConstStr + from + ",";
    else
        return f(ConstStr, from, to - 1) + ConstStr + to + ",";
}

Finally, you can pharse the sentence with "," like this:

C#

string str = f("Mehdi", 1, 5);
string[] strArr = str.Split(new char[] { ',' });
