In this query, we have used the Asc function as follows:

Expr1: Asc("x")

This query will return the NUMBER code for "x" and display the results in a column called Expr1. You can replace Expr1 with a column name that is more meaningful.

AscValue: Asc("x")

The results would now be displayed in a column called AscValue.
