   # Proposed changes
   
   Add call once to adding third parameter of aes_decrypt type function.
   
   ## Problem summary
   
   The problem is an exception when doing analyze:
   java.lang.IllegalStateException: exceptions :
   errCode = 2, detailMessage = select list expression not produced by 
aggregation output (missing from GROUP BY clause?): xxx
   
   The scenario is: 
   select aes_decrypt(xxx,xxx) as c0 from table group by c0;
   
   Analyze of problem:
   The direct problem is mismatched of slotref, and this mismatched due to the 
mismatched of parameter number of aes_decrypt function. When debuging, we can 
see the slotref of group column is added to ExprSubstitutionMap, but can not 
matching with select result columns. And this is because when substiting expr 
it will analyze again, so the parameter would be added twice. This will cause 
the mismatching of function, so it would not be substitute as a slotref, the 
exception would be throw.
   
   Fix:
   Add call once to adding third parameter of aes_decrypt type function. 
Compare the child we want to add to the last child of function. If they are the 
same, do not add it.
   
   Describe your changes.
