Access 2007 Query to return latest date note from subquery -


i have 2 tables joined projectid in access 2007. table structure of primary table (a)

projectid | custid  1        |   5  2        |   8 

i have secondary table (b) of notes on projectid, structured

projectnotesid | projectid |  note    | createdate ---------------------------------------------------  1             |  1        |  note11  | 1/2/2015  2             |  1        |  note12  | 2/2/2015  3             |  2        |  note21  | 4/8/2015  4             |  2        |  note22  | 3/5/2015 

i want return of, or part of, table a, latest note of table b,

projectid | custid | note    | createdate ------------------------------------------  1        |  5     | note12  |  2/2/2015   2        |  8     | note21  |  4/8/2015 

i can (and have done) php & mysql, can't work in access 2007. can return projectid , latest note date following query in access 2007

select projectid, max(createdate) maxofcreatedate table b group projectid; 

i have tried unique values, etc., can't results looking for.

thanks!

i found answer. first, changed query got latest date, , instead got max projectnotesid. query ::

select projectid, max(projectnotesid) maxofprojectnotesid  table b group projectid; 

i created second query combining above query , table b, joining query.maxofprojectnotesid <-> tableb.projectnotesid, , query.projectid <-> tableb.projectid. second query pulls values tableb.
