I tried downloading the sql (sql.lib and sqld.lib) drivers to the MSCV and MINGW files ; it did not work. I then tried through QODBC3 driver and its still not connecting to the database.
I get the following error message.
13:20:05: Starting
C:\build-test1-Desktop_Qt_5_14_1_MinGW_64_bit-Debug\test1.exe ...
13:21:17:

//QSqlDatabase db = QSqlDatabase::addDatabase("QODBC3","QMYSQL");
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC3","hello");
// db.setDatabaseName("Driver={MySQL ODBC 8.0 ANSI Driver};DATABASE=hello;");
db.setHostName("127.0.0.1");
db.setDatabaseName("hello");
db.setUserName("localhost");
db.setPassword("");
if (db.open()){
QMessageBox::information(this,"Connection","Database connected succesfully");
}
else {
QMessageBox::information(this,"Connection","Database not connected succesfully");
This is my code, also I did add sql in the pro files.

I have simple vibe-D program which is trying to connect to SQL:
import std.stdio;
import mysql;
import vibe.d;
void main()
{
MySQLPool db_pool = new MySQLPool("localhost","root","","dbname",3306);
Connection db = db_pool.lockConnection();
// same thing happens with:
// string connectionStr = "host=localhost;port=3306;user=root;db=dbname";
// db = new Connection(connectionStr);
}
(I deleted everything else for simplification)
Dependencies:
"dependencies": {
"mysql-native": "~>3.2.0",
"vibe-d": "~>0.9.4"
}
And it fails to connect with:
object.Exception#../../../.dub/packages/vibe-core-1.22.4/vibe-core/source/vibe/core/net.d(256): Failed to connect to [0:0:0:0:0:0:0:1]:3306: refused
When I try it without vibe-d in the dub project (using phobos sockets) it connects with no problem. What am I doing wrong?
that's an ipv6 address.... is your mysql listening on that interface? might help trying 127.0.0.1 instead of localhost and seeing what happens.
can also consider reconfiguring mysql to listen on all interfaces too, including the ipv6
I am trying to connect to my pythonanywhere DB from a local python file, using the following code.
import MySQLdb, sshtunnel
sshtunnel.SSH_TIMEOUT = 5.0
sshtunnel.TUNNEL_TIMEOUT = 5.0
queryAdd = ("INSERT INTO `****$geo***`.O***"
"(name, address) "
"VALUES (%s, %s)")
with sshtunnel.SSHTunnelForwarder(
('ssh.pythonanywhere.com'),
ssh_username='*******', ssh_password='*******',
remote_bind_address=('*****.mysql.pythonanywhere-services.com', 3306)
) as tunnel:
connection = MySQLdb.connect(
user='******',
passwd='********',
host='127.0.0.1', port=tunnel.local_bind_port,
db='****$geo******',
)
cursor = connection.cursor()
for row in dl:
tup=(row['name'],row['address'])
cursor.execute(queryAdd, tup)
connection.commit()
However, as soon as the code is run, I get the following error:
MySQLdb._exceptions.OperationalError: (2013, 'Lost connection to MySQL server during query')
There is no delay between creating the connection and running the query. What am I doing wrong?
You need to do everything inside your with block as the tunnel is gone when you go outside of the context.
I am trying to connect to A DB on Redshift in r using following syntax (I am using a Mac):
