Question

I am trying to grouped by attribute 2 [pos] of sqlite database and then get max value of attribute 1 [tagcount].
This works fine in sqlite3 on cygwin.

 sqlite> 
     select max(tagcount),pos 
     from (
          select tagcount,pos 
          from sense,synset 
          where sense.synsetid=synset.synsetid 
            and wordid in(
                      select wordid 
                      from word 
                      where lemma="run"
                         )
           ) 
      group by pos 
      order by tagcount DESC; 

Resulting in the following output

106|v

18|n

But when I copy the exact query in VB.net it gives me the following error

You tried to execute a Query that does not include specific expression
‘tagcount’ as part of aggregate function

What change should be made in the query so that VB.net does not complaint about it?

Answer 1

It may be your order by as it’s not an aggregated value and isn’t included in your group by.
