Thank you Richard, your expression returns ROWS and can't be used in SQLFORM.grid. When I removed the last select
db(~db.pc.id.belongs(db(db.assigned.id > 0)._select(db.assigned.id)) then I get File "E:\web2py 2.9.12\gluon\sqlhtml.py", line 2139, in grid field_id = tables[0]._id IndexError: list index out of range Dave, the tables are related. e.g. the table "assigned" has a field "computer" of type db.pc Thanks, PT On Friday, September 4, 2015 at 3:23:47 PM UTC-5, Dave S wrote: > > I'm puzzled about the why ... > > On Friday, September 4, 2015 at 12:42:32 PM UTC-7, Richard wrote: >> >> db(~db.pc.id.belongs(db(db.assigned.id > 0)._select(db.assigned.id >> )).select(db.pc.ALL) >> >> Richard >> >> >> >> On Fri, Sep 4, 2015 at 3:35 PM, P T <[email protected]> wrote: >> >>> >>> Hello Forum, >>> >>> Please help me in getting the equivalent DAL query for the following SQL >>> query.
