Why does a null query always return a database type object?

Question

Database

I can’t understand why the cursor always needs to be moved when fetching data from the database and getting a value with index 1, not 0. It’s just that if I do without it, I get a link to the connection instance object (or whatever it’s called correctly - correct pliz) type: ddbc.driver.bla-bla-bla

auto lastparsetime = stmt.executeQuery("SELECT LastParseTime FROM stat where URL='" ~ url ~ "';");
while(lastparsetime.next())
{
  dt = (DateTime.fromSimpleString(lastparsetime.getString(1)));
}

Why is it impossible to do without While when fetching a value? Is it the same in C#?
PS I use this driver code.dlang.org/packages/ddbc

Answer 1

So in the rows of the database, the numbering in AutoIncrement starts from 1, this is in arrays from 0
