Rule to evaluate if a value exists in a table

I have a operations that is writing 6 values to a table 

Class BHS.Custom.MosaiqCloudPatientsTable Extends (%Persistent, Ens.Request) [ Inheritance = right ]


I need to create a routing rule to evaluate a field in an hl7 ORU message ,  see if it exists in the account column of the table. If it does then allow the message to pass.

This table is not a lookup table. How can I get a function to evaluate a field to this  table?

Hope this satisfies your need:

I created a new class (called Test.Common.Utility) to do this.  It performs a simple SQL select on a %Persistent table to find a specific value in a column.  The code is as follows:

Include EnsHL7
Class Test.Common.Utility Extends Ens.Rule.FunctionSet
ClassMethod CheckTable(pCSN As %String) As %Boolean
    Set output = $$$NO
    &SQL(Declare C11 Cursor for select CSN into :tCSN from Test_Record.SampleTable where (CSN = :pCSN))
    &SQL(Open C11)
    &SQL(Fetch C11)
    if SQLCODE = 0 { Set output = $$$YES }
    &SQL(Close C11)

    Quit output

My rule to implement this function looks like:
