Get the total number of previous records

Question

I am creating a query in MS Access that needs to update newly created field with the total number of previous records. Something like this:

Original table:

SQL

|  ID | Name |
--------------
|  1  | Mark |
--------------
|  2  | Mich |
--------------
|  3  | Isak |
--------------

Now I add another column ( of type int ), e.g. Ordinal_Number :

SQL

|  ID | Name | Ordinal_Number |
-------------------------------
|  1  | Mark |                |
-------------------------------
|  2  | Mich |                | 
-------------------------------
|  3  | Isak |                | 
-------------------------------

Now I need to fill Ordinal_Number with the number of previous records :

SQL

|  ID | Name | Ordinal_Number |
-------------------------------
|  1  | Mark |       0        |
-------------------------------
|  2  | Mich |       1        | 
-------------------------------
|  3  | Isac |       2        | 
-------------------------------

I couldn't even get the idea how to try fighting this problem so I am asking here.

/* fill Ordinal_Number with the number of previous records */
Not clear. Do you want to insert the previous ID values in Ordinal_Number column? Like Ordinal_Number = 1 when ID = 2

* fill Ordinal_Number with the number of previous records */

Everything is crystal clear : I want to insert the number of previous records in that field, like Ordinal_Number = COUNT(*) FROM MyTable but it should count the number of current record's predecessors. Something like Ordinal_Number = COUNT(*) FROM MyTable WHERE Ordinal_Number <= current_records_Ordinal_Number_value;

Solution 1

When you are inserting data in table, before inserting find maximum number of ID and then you can pass that ID value - 1, with name to save in table

I need to add a new integer field into existing database. Therefore I need to update that field immediately after I add it.
