Computing not null values in a CDT

Question

Hi, 
 I have a CDT which has around 50 attributes, I am required to find the count of not null attributes in my CDT. Is there a way I can do this by not creating a counter which would get updated after 70 if-else checks? 
 For Example: 
 Employee_cdt{fName:"Abc",lName:"Def",mName:"",empId:1234,empDept:""...} 
 A rule to return the not null attributes for Employee_cdt. 
 
 Thanks, 
 Arjun

Is below your requirement? 
 
Input: Employee_cdt { fName:"Abc",lName:"Def",mName:"",empId:1234,empDept:""} 
Output: 3 or {"fName","lName" , "empId"} 
 
Please check the below code: 
 
with( 
 local!empCDT: { 
 name: "Ravi", 
 email: "rr@gmail.com", 
 phone: 123456, 
 age:"", 
 gender: "M", 
 }, 
 local!cdtAttributes: {"name", "email","phone","age","gender"}, 
 local!notNullAttributes: apply( 
 rule!test_checkAttriuteValue( 
 cdt: local!empCDT, 
 attribute: _ 
 ), 
 local!cdtAttributes 
 ), 
 local!notNullAttributes 
) 
 
/* Definition of rule!test_checkAttriuteValue */ 
 
/* This rule have 2 parameters, cdt and attribute*/ 
 
with( 
 local!attributeValue: index( 
 ri!cdt, 
 ri!attribute, 
 null 
 ), 
 if( 
 isnull(local!attributeValue), 
 ri!attribute, 
 null 
 ) 
)

Hi Arjun, 
 
I understood your question. The result should me mName and empDept correct? 
You have to do take all columns/attributes name as array and perform below small line of code 
 
load( 
 local!CDT: {fName:"Abc",lName:"Def",mName:"",empId:1234,empDept:""}, 
 a!forEach( 
 items: {"fName", "lName", "mName", "empId", "empDept"}, 
 expression: if( 
 rule!APN_isBlank(index(local!CDT, fv!item, null)), 
 fv!item, 
 {} 
 ) 
 ) 
) 
 
this will give desired out put. 
 
List of Text String: 2 items 
 "mName" 
 "empDept"

Sorry you are giving values which are output of null values, he asked for not null values

a!localVariables(
local!CDT: {
fName: "Abc",
lName: "Def",
mName: "",
empId: 1234,
empDept: ""
},
a!forEach(
items: {
"fName",
"lName",
"mName",
"empId",
"empDept"
},
expression: if(
a!isNotNullOrEmpty(index(local!CDT, fv!item , null)),
fv!item,
{}
)
)
)

This works
