Sort Oracle Strings Numerically: ORDER BY Guide

To achieve sorting of Oracle strings numerically, you can use the ORDER BY clause in Oracle and combine it with the REGEXP_SUBSTR function to extract numbers from the string for sorting.

Here is an example:

SELECT column_name
FROM table_name
ORDER BY TO_NUMBER(REGEXP_SUBSTR(column_name, '\d+'));

In the above example, ‘column_name’ is the name of the string column to be sorted, and ‘table_name’ is the name of the table containing this column. Extract the numbers from the string using the REGEXP_SUBSTR function, convert the extracted numbers to numeric type using the TO_NUMBER function. Finally, use the ORDER BY clause to sort the strings by numbers.
