Hi,
I'm trying to call an expression through a query result, is there any way for it to be done? Like, say, calling an expression by it's uuid?
Thanks

I know passing rule references to other rules as rule inputs. Consider the following rule which takes in a rule reference as input and executes it inside.
Rule:
executeMyRule(ruleToBeExecuted<AnyType>, dataToBePassed<AnyType>){
apply(ri!ruleToBeExecuted, {ri!dataToBePassed})
}
And we can call this rule as follows...
rule!executeMyRule(fn!dollar, "345")
rule!executeMyRule(fn!dollar, {"123", "345"})
This procedure can be used to create application level common rules where the rules to be executed/applied are not decided at design time but rather decided at run time. A most common use-case is to pass formatter rules to a SAIL component which applies the format passed in as a rule input.
If you want to call an expression through a query result, can you see any possibility of getting rule references(rule!ruleName as string) from database/query and pass it to the above rule ?
I might have misinterpreted your question but felt like worth sharing.
