The Execute SOQL action takes a SOQL string and executes the query, returning the records that you specify. It comes packaged with a graphical SOQL Builder component that you can add to a flow screen to let your users create their own queries at runtime.
New for V1.2
Previously if you tried to pass a “standard” Flow date via a mergefield into this action as part of the SOQL string, it would get confused. Flow dates are now converted properly.
Additionally, the class was fixed to work properly with Schedule triggers.
