DYNAMIC VALUE FILL IN Oracle query

Well, first of all I'd place your integer IDs in a List rather than an array. You can then add only a few or a lot of integers as you please.

With the help of a bit of LINQ you can then easily build your SQL query:

using System.Collections.Generic;

using System.Linq;

//....

var list = new List{23, 2, 2, 4, 5};

list.Add(7); // add as many other integers as you like

var query = list.Select(i => "'" + i + "'");

string s = String.Join(",", query.ToArray());

string sql = "SELECT ID,PAYMENT_RECEIVE_DATE FROM PAYMENT_DETAILSWHERE P_ID IN(" + s +")";
