SUM and COUNT

Posted on 2011-03-02

Hi everyone!!!

What is the query to perform a SUM and COUNT in Table A where in Table B there is a column of true and false that will be the condition for the SUM and COUNT function?

Table A has the column name "numbers".  Table B has a column name "flag"  of true and false.  Both tables share the same unique ID of course.

So my goal is to get the SUM and COUNT of the column "numbers" in tableA if FLAG = true in TableB and  if FLAG = false in TableB.

I need the two SUM and COUNT values.
