Okay, I'll put that down to a misunderstanding of the man page as I
can clearly see that
'select' => [ { distinct => [ 'm2.inventorycategoryid', 'c2.name' ] }
will produce:
select distinct (m2.inventorycategoryid, c2.name)
Which of course is not valid SQL as this is not one column
this can be fixed again by referencing:
select => [ \"distinct m2.inventoryitemid, c2.name"]
You can pass distinct => 1 to the attributes to affect a GROUP BY clause
containing all columns, which should be logically equivalent to SELECT
DISTINCT
{
select => [ 'm2.inventorycategoryid', 'c2.name' ],
distinct => 1,
}
