Using NOTIN and Lookup in the method

Any syntax help, i want to check different msg types and then reach out to the value in that particular segment. Here is example, i want to get SSNNumber from a method. Trying to use NOTIN, and Lookup

Class Training.RulesFunctionSet Extends Ens.Rule.FunctionSet

{

ClassMethod getEmiratesId(pHL7 As EnsLib.HL7.Message) As %String
{
SET msgType = pHL7.GetValueAt("MSH:MessageType.TriggerEvent")
 

IF msgType NotIn "A39,A40,O01,O11,O09,R01" {
return pHL7.GetValueAt("PID:SSNNumberPatient")}

IF msgType In "A39,A40" {
 return pHL7.GetValueAt("PIDgrp(1).PID:SSNNumberPatient")}
 
IF msgType In Lookup("AllowsMsgTypes",HL7.{MSH:SendingFacility.NamespaceID},,) {
 return pHL7.GetValueAt("PIDgrpgrp(1).PIDgrp.PID:SSNNumberPatient")}
}
}

You can use the contains operator "["

IF ",A39,A40,O01,O11,O09,R01,"'[(","_msgType_",") {
return pHL7.GetValueAt("PID:SSNNumberPatient")}

I'm not sure about the lookup syntax, I haven't used it.

The code that I sent is not contains. It has an apostrophe in front of the open square bracket. If you want to check if it's contained in the list it will just be a open square bracket 

"NotIn" is not part of InterSystems ObjectScript. Also not "in" . This is SQL slang
Alternative to the proposal of @Adrian Zeeman  you may try this construct:

if  '($LF($LFS("A39,A40,O01,O11,O09,R01",msgType)) { . . . 

Hi Ahmad,

In the class Ens.Util.FunctionSet exists the methods In and NotIn, that's work if comma-delimited string.

To check if a value is not in a LookupTable test if the returns of method Lookup is empty.
