Nintex Form execute SQL with current user credentials

Hi there,

I'm trying to execute an SQL SELECT statement with the current user credentials. Because of security reasons I need to overmit the SQL statement so every user opening the SharePoint Form is getting his/her current history from the database.

At the moment I just can set a single SQL- or Windows user in the secure store on the central administration of the SharePoint.

Is there another way to manage it to get the current history from the current logged in user from the database?

Thanks a lot,

Steffen
