Hi,
thanks for previous response...
i have observed a singular behavior...i have a DB with 220000
entry...the keys are in the range 15 - 220,000

If I get the key 2,000,000 the DB response correctly "no record found
for key 2,000,000" ...

but if i get the key 1 (or any minor 15) the DB response always with key
15 (the first in the DB)...

Can you give us some more information?
* Are you sure that keys 1-14 are not in the DB?
* What is the format of the keys? Are you using integers? Strings?
* What method are you using to retrieve the key/data pairs? Could you
provide a sample of that code?
* Can you provide code that will reproduce this problem?

Thanks,
Alex

Yes...because i load a dB from file... and i sure that keys 1-14 not exist..

key are long..

This is my function for query a singular item:

....
long item = 1;
show_item_table1(table1DB, item);
....

int show_item_table1(MyDb &table1DB, long &item)
{
Dbc *cursorp;
try {
table1DB.getDb().cursor(NULL, &cursorp, 0);

Dbt key(&item,sizeof(long)) ;
Dbt data;

int ret = cursorp->get(&key, &data, DB_SET_RANGE);
if (!ret) {
do {
Table1Data table1Item(data.get_data());
table1Item.show();

} while(cursorp->get(&key, &data, DB_NEXT_DUP) == 0);
} else {
if (ret)
std::cerr << "\nNo records found for key: " << item;
}

} catch(DbException &e) {
table1DB.getDb().err(e.get_errno(), "Error in show_all_records");
cursorp->close();
throw e;
} catch(std::exception &e) {
cursorp->close();
throw e;
}

cursorp->close();
return (0);
}


Table1Item have 2 long members key e value;
