Hi Many
GetReturn<-function(code,date)
{
db<-"C:/Test.mdb"
channel<-odbcConnectAccess(db)
ssql<-paste("select * from tblCalendarDate Where CalendarID
=",code,"and DateRebal >=",date)
print(ssql) # so as i can see what ssql contains
mydata<-sqlQuery(channel,ssql)
mydata
}
[snip]
This is the content of my table tblCalendarDate:
CalendarID DateRebal
1 29/09/2006
1 10/10/2006
1 20/10/2006
1 31/10/2006
1 10/11/2006
1 20/11/2006
Actually, the channel is open but the query on the table did not
perform the query correctly, here is the
result of the function when i run GetReturn(1,"2007-03-01") for example:
Something with the formatting of the date goes wrong as I think. In the
table tblCalendarDate you have it
like *29/09/2006* but in your function you have it as *"2007-03-01"*.
Dig deeper by experimenting with
the dates format. You can experiment in Access itself to see what kind
of dates Access accepts.
