Solution

The language of the text is SQL (Structured Query Language). Here is the query you need:

SELECT 
    meter_number, 
    LPAD(meter_number, 10, '*') AS updated_meter_number
FROM 
    meter
ORDER BY 
    meter_number ASC;

This query does the following:

  1. Selects the meter_number from the meter table.
  2. Uses the LPAD function to left pad the meter_number with '*' until it becomes a 10 character length field. This new field is given an alias name 'updated_meter_number'.
  3. Orders the result in ascending order based on meter_number.
