New Comment:
Numeric type returns invalid result using
ibase_fetch_row/ibase_fetch_object (Windows NT).
Numbers stored as an InterBase/Firebird numeric/decimal datatype
beyond
the bounds of the PHP integer type (> 2147483647), do not return a
float
type but cause an overflow
Example:
2303511415 (decimal 10,0) returns -1991455881
PHP/Firebird example script:
$sql = "create table temp (large_number numeric(10,0))";
$result = ibase_query($sql,connection());
if (!$result) {
exit;
}
ibase_commit();
$sql = "INSERT INTO temp VALUES (2303511415)";
$result = ibase_query($sql,connection());
if (!$result) {
exit;
}
$sql = "SELECT large_number FROM temp WHERE large_number =
2303511415";
$result = ibase_query($sql,connection());
if (!$result) {
exit;
}
while ($row = ibase_fetch_row($result)) {
print($row[0]);
}
ibase_free_result($result);
$sql = "drop table temp";
$result = ibase_query($sql,connection());
if (!$result) {
exit;
}
ibase_commit();
