Hi, How do i connect my local sql server database(external database) to App

In order to allow Appian customers in the cloud access to computer resources on a private network from an Appian instance, an IPSec VPN connection can be configured. Please refer to the following topic in our docs for more information: forum.appian.com/.../Cloud_VPN_Integration
This will allow you to read / write data to and from a relational database hosted locally (through Appian, not through phpMyAdmin).

Moreover, you can have that external database configured as a pre-defined data source to make it easier for application developers to connect to it as they build their process applications. Additional information can be found here: forum.appian.com/.../Query_Database_Smart_Service

Thank you so much..
