Hi, All
I have a problem and need to help. When I insert a lot of records into a
table in access2k db with TADOTable component, I found some records can be
duplicated although I have already defined the uniqe primary key in the
table. The problem may be out of Date/Time field. but I cannot figure it out
why some records can be duplicated, even cannot be queried.
BTW, whether I must use DateTimeFormat function to convert Date/Time field
before appending a record with a Date/Time field to the table?
frmdm->ADOTableLocal->Close();
frmdm->ADOTableLocal->TableName = "test";
frmdm->ADOTableLocal->Open();
for (int i = 0; i < Pnum; i++) {
if (p[i] != 0) {
frmdm->ADOTableLocal->Append();
frmdm->ADOTableLocal->FieldByName("Fqnum")->AsInteger =
PFstid[i];
frmdm->ADOTableLocal->FieldByName("RainID")->AsInteger =
Pstid[i];
frmdm->ADOTableLocal->FieldByName("DTime")->AsDateTime =
CurrTime;
frmdm->ADOTableLocal->FieldByName("RainValue")->AsFloat = p[i];
frmdm->ADOTableLocal->Post();
}
}
thanks in advance
