how to take data from external SQL database using Nintex Form 2016 standard (on-premise)

Hi,

I've Nintex Form 2016 (on-prem), i suppose it is the standard version cause I cannot see the "SQL Request" control. I've to take data from an external SQL database. I know that Nintex Form Enterprise had the "SQL Request" control for this, but in standard version is not available. Is there a way to do the same thing in the standard version?.

Thanks
