To sort an alphanumeric string in Oracle, you can use the NLSSORT() function in a ORDER BY clause. Here is an example of how to sort an alphanumeric string in Oracle:

1
2
3
SELECT column_name
FROM table_name
ORDER BY NLSSORT(column_name, 'NLS_SORT=BINARY_AI');


In this example, replace column_name with the name of the column containing the alphanumeric strings you want to sort, and table_name with the name of the table containing the data. The BINARY_AI parameter in the NLSSORT() function specifies a binary sort in a case-insensitive manner.


You can also use other parameters in the NLSSORT() function to customize the sorting behavior, such as NLS_SORT=GENERIC_M, NLS_SORT=XWEST_EUROPEAN, etc., depending on your specific requirements.
