CodeIgniter provides drivers for all the famous databases like MySQL, Oracle and MS SQL, but if somebody wants to use SAP Sybase SQL Anywhere with CI then it's difficult to write a new driver. I have written a CodeIgniter DB driver which supports SQL Anywhere. Please follow the below steps.
1. Create a new folder in sasql in "system/database/drivers".
2. Create below files in sasql folder.
Content for above files:
sasql_driver.php
