EXAMPLE  COUNT Functions
This example demonstrates how to count the number of values and nonnull values within a group.
Functions:
Item  Description 

COUNTA Function  Generates the count of nonnull rows in a specified column, optionally counted by group. Generated value is of Integer type. 
COUNTDISTINCT Function  Generates the count of distinct values in a specified column, optionally counted by group. Generated value is of Integer type. 
Source:
In the following example, the seventh row is an empty string, and the eighth row is a null value.
rowId  Val 

r001  val1 
r002  val1 
r003  val1 
r004  val2 
r005  val2 
r006  val3 
r007  (empty) 
r008  (null) 
Transformation:
Apply a COUNTA
function on the source column:
Transformation Name 


Parameter: Formula type  Single row formula 
Parameter: Formula  COUNTA(Val) 
Parameter: New column name  'fctnCounta' 
Apply a COUNTDISTINCT
function on the source:
Transformation Name 


Parameter: Formula type  Single row formula 
Parameter: Formula  COUNTDISTINCT(Val) 
Parameter: New column name  'fctnCountdistinct' 
Results:
Below, both functions count the number of values in the column, with COUNTDISTINCT
counting distinct values only. The empty value for r007
is counted by both functions.
rowId  Val  fctnCountdistinct  fctnCounta 

r001  val1  4  7 
r002  val1  4  7 
r003  val1  4  7 
r004  val2  4  7 
r005  val2  4  7 
r006  val3  4  7 
r007  (empty)  4  7 
r008  (null)  4  7
