Why do Microsoft goes with sql statements instead of using x++ select statements

Hi experts, 
I came across a method in LedgerJournalTable (Table object) under the method numOfVouchers(). This can be achieved through x++ statements as well. But I just want to understand why Microsoft went with sql statement instead of using X++ statements here. This method is used in posting a journal to check whether there are any journal lines there are to be posted. Any inputs is appreciated. 
 
Regards, 
John

    Hi,

    it would be great if u can share the code of the method, because not all of us have access to our devBoxes when looking at questions:

    But in general based on Mohamed's comment about distinct, then we can still sometimes achieve sth similar to distinct using group by

    for example these two sentences below give the same result
     
    select distinct AccountNum  from custTable
    select AccountNum from custTable group by AccountNum

    because in X++ select statement there's no such thing as a distinct keyword, which is why they use sql statement.
