You can get one connection object and close it :)
```D
import hunt.database;
class AvmTest {
private Database _db;
this() {
_db = new
Database("mysql://testusr:x...@test.srv.com:3910/test");
}
string[string][] getHostname() {
string[string][] data;
auto conn = _db.getConnection();
foreach(row; conn.query("SELECT host_name FROM
hosts_coll"))
{
string[string] host;
host["HostName"] = row["host_name"];
data ~= host;
}
conn.close();
return data;
}
}

Is this database library compatible with the fiber programming

Yes.
There are no conflicts.

Hi,
Maybe port 8080 is blocked, because there is an instance of

Your program is crashing probably because you are dereferencing
a null/ dangling pointer.
Build your program in debug mode and run it in a debugger, that
way you will get a backtrace telling you the exactly line of
the code when it happens.
Hi Boris,
I tired to build the code in debug mode and ran the program in
debugger , the debugger is complaining about the line "this.conn

connection string and the info is correct.

The instance variable in the D code, `conn`, doesn't have a

You need to specify the type of conn. private Connection conn;
auto avmconnect()
{
auto connectionStr =
"host=test.srv.com;port=3910;user=testusr;pwd=#;db=test";
Connection conn = new Connection(connectionStr);
scope(exit) conn.close();
}
You are using a new connection here, maybe you want to use
this->conn instead of Connection conn;
By the way you are closing it everytime with scope(exit).
