sql - MS Access 2002/VBA - join a number of lookup tables to main query? -


consider:

contact ======= contact_id, not null name, not null electorate_id, null allowed member_type_id, null allowed  member_types ===========+ member_type_id member_type  electorates =========== electorate_id electorate

these tables wish use populate form. have tried few ways, query returns no data:

select contact_id, name, member_type, electorate contact left join member_types  on contacts.member_type_id=member_types.member_type_id, contacts left join electorates on contacts.electorate_id=electorates.electorate_id

also:

"select contact_id, name, member_types.member_type, electorates.electorate contacts, member_types, electorates contacts.contact_id=" & contact_id & "  , electorates.electorate_id=contacts.electorate_id , member_types.member_type_id = contacts.member_type_id"

both of these fail. can suggest query works please?

select contact_id, name, member_type, electorate contact  left join member_types on contact.member_type_id=member_types.member_type_id left join electorates on contact.electorate_id=electorates.electorate_id

don't re-specify contact table in row 4. have contacts in on clauses, not contact.

hopefully left joins supported in access 2002.

also, second query work if both electorate_id , member_id set. that's why need left join.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
