Driver not loaded mySql

I'm using Pycharm with Python3.9 and PyQt 5.15.2 and QSqlDatabase I followed the instructions on https://doc.qt.io/qt-5/sql-driver.html#qmysql How to Build the QMYSQL Plugin on Windows. I used the mingw81_64 compiler. The file qsqlmysql.dll has been generated and I have copied it to PyQt5/Qt/plugins/sqldrivers in my virtual environment. I also copied the file libmydql.dll to PyQt5/Qt5/bin in my virtual environment. If I execute database.drivers() I get the following ['QSQLITE', 'QMARIADB', 'QMYSQL', 'QMYSQL3', 'QODBC', 'QODBC3', 'QPSQL', 'QPSQL7']. I got the following error "Driver not loaded" I also tried downloading the file qsqlmysql.dll from https://github.com/weldermarcosxd/pyqt5-mysql/blob/master/Lib/site-packages/PyQt5/Qt/plugins/sqldrivers/qsqlmysql.dll but I got the same error. I'm using this database https://remotemysql.com/ but I also tried with a local MySql Server and I got the same error. SQLlite works fine.
class Login(QWidget):
def __init__(self):
super().__init__()
self.init_widgets()
self.set_styles()
self.connectSQLlite()
def connect(self):
server = 'remotemysql.com'
database_name = '****'
user_name = '****'
password = '****'
self.database = QSqlDatabase.addDatabase("QMYSQL")
self.database.setHostName(server)
self.database.setDatabaseName(database_name)
self.database.setUserName(user_name)
self.database.setPassword(password)
ok = self.database.open()
if ok:
print('Success')
else:
print(self.database.lastError().text())
app = QApplication(sys.argv)

You have to compile plugin with same compiler that your Qt binaries were compiled.

Connect to Filemaker Database using JDBC, Python, and JayDeBeApi

I'm trying to write an AWS Lambda Python Package that will connect to a FileMaker database over JDBC. To test, I've launched an EC2 instance with the Lambda Linux AMI, and created a virtualenv (/venv) that I'm testing in. I've uploaded the fmjdbc.jar to the instance using WinSCP to /venv/lib/fmjdbc.jar. The code uses JayDeBeApi, following the usage example here: https://pypi.python.org/pypi/JayDeBeApi/#usage
My code so far is the following:
import jaydebeapi as jdb
driverclass = 'com.filemaker.jdbc.Driver'
jdbcURL = 'jdbc:filemaker://url:port;database'
jar = '/home/ec2-user/lambda-test-project/venv/lib/fmjdbc.jar'
print jar
conn = jdb.connect(driverclass,[jdbcURL,'username','password'],jar)
Which gives me the error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/ec2-user/lambda-test-project/venv/local/lib/python2.7/site-package s/jaydebeapi/__init__.py", line 359, in connect
jconn = _jdbc_connect(jclassname, jars, libs, *driver_args)
File "/home/ec2-user/lambda-test-project/venv/local/lib/python2.7/site-package s/jaydebeapi/__init__.py", line 183, in _jdbc_connect_jpype
return jpype.java.sql.DriverManager.getConnection(*driver_args)
jpype._jexception.SQLExceptionPyRaisable: java.sql.SQLException: No suitable driver found for jdbc:filemaker://<MY URL STUFF IS HERE>
How can I get the jdbc driver to be read by Python's virtual environment? I'd like to have this code work in a Lambda package eventually, so I'm hoping there's a solution that can be integrated to the Python code that will work repeatedly on newly created servers.

You can use jpype package to set driver for python. I used it for connecting Oracle DB before. There is my sample code which may be useful for you.
import jaydebeapi,jpype
classpath = "your jdbc jar driver path"
jvm_path = "/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.36.x86_64/jre/lib/amd64/server/libjvm.so" #your java vm path
jpype.startJVM(jvm_path, "-Djava.class.path=%s" % classpath) #start jvm based on the driver
conn = jaydebeapi.connect(xxxxxx)

No module named usb.core

How can I remove this error in the below mentioned program? The error iI'm getting is
ImportError: No module named usb.core
and my code is:
import usb.core
import usb.util
# find our device
dev = usb.core.find(idVendor=0xfffe, idProduct=0x0001)
# was it found?
if dev is None:
raise ValueError('Device not found')
# set the active configuration. With no arguments, the first
# configuration will be the active one
dev.set_configuration()
# get an endpoint instance
cfg = dev.get_active_configuration()
intf = cfg[(0,0)]
ep = usb.util.find_descriptor(
intf,
# match the first OUT endpoint
custom_match = \
lambda e: \
usb.util.endpoint_direction(e.bEndpointAddress) == \
usb.util.ENDPOINT_OUT)
assert ep is not None
# write the data
ep.write('test')

OS is windows 8 64-bit [...]
ValueError: No backend available
Allow me to translate: You forgot to install the correct USB driver.
USB devices need a driver to work in Windows. Look at PyUSB website for details, and use Zadig to generate and install the driver (e.g. LibUSB-Win32) for you. This program takes care of the certificate that Windows 8 wants to see for your drivers inf file.
Btw: The VID you should use for USB development is 0x4242.

For error:
C:\Users\RAHUL\Desktop\python progrms\USBsample.py, line 5, in <module>
dev = usb.core.find(idVendor=0xfffe, idProduct=0x0001) File "C:\Python27\lib\site-
packages\usb\core.py", line 864, in find raise ValueError('No backend available')
ValueError: No backend available
Download and install libusb-win32-devel-filter-1.2.6.0.exe. It should work.

python -m pip install pyusb libusb
Fixed this for me.

pyodbc: .mdb connection error on ubuntu

I am trying to access a .mdb file which located on my system. My Code look slike this :
import csv
import pyodbc
MDB = '/home/filebug/client/my.mdb'
DRV = '{Microsoft Access Driver (*.mdb)}'
PWD = 'mypassword'
conn = pyodbc.connect('DRIVER=%s;DBQ=%s;PWD=%s' % (DRV,MDB,PWD))
print conn
curs = conn.cursor()
SQL = 'SELECT * FROM InOutTable;' # insert your query here
curs.execute(SQL)
rows = curs.fetchall()
curs.close()
conn.close()
But I am facing following Error :
Traceback (most recent call last):
File "mdb.py", line 8, in <module>
conn = pyodbc.connect('DRIVER=%s;DBQ=%s;PWD=%s' % (DRV,MDB,PWD))
pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')
I have pyodbc-3.0.6-py2.7-linux-i686.egg installed on my system. using Ubuntu 12.04
Can any one sya me what is wrong here

I get this info from http://www.easysoft.com/developer/interfaces/odbc/linux.html
In this case unixODBC could not locate the DSN "dsn_does_not_exist" and hence could not load the ODBC driver. Common reasons for this error are:
The DSN "dsn_does_not_exist" does not exist in your USER or SYSTEM ini files.
The DSN "dsn_does_not_exist" does exist in a defined ini file but you have omitted the "Driver=xxx" attribute telling the unixODBC driver manager which ODBC driver to load.
The "Driver=/path_to_driver" in the odbcinst.ini file points to an invalid path, to a path to an executable where part of the path is not readable/searchable or to a file that is not loadable (executable).
The Driver=xxx entry points to a shared object which does not export the necessary ODBC API functions (you can test this with dltest included with unixODBC.
The ODBC driver defined by DRIVER=xxx in the odbcinst.ini file depends on other shared objects which are not on your dynamic linker search path. Run ldd on the driver shared object named by Driver= in the odbcinst.ini file and see what dependent shared objects cannot be found. If some cannot be found than you need to defined your LD_LIBRARY_PATH environment variable to define the paths to any dependent shared objects or add these paths to /etc/ld.so.conf and rerun ldconfig.

How connect to mysql with python via odbc

Im running mysql, pyodbc, python 2.7 loaded on Fedora 14 x64.
Odbcinst.ini is:

#Setup = /usr/lib/libodbcmyS.so
Driver64 = /usr/lib64/libmyodbc5.so
Setup64 = /usr/lib64/libodbcmyS.so

Odbc.ini is :

Driver = MySQL
Database = mysql
Server = localhost
Socket = /var/lib/mysql/mysql.sock

Mysql.sock is empty?
/var/lib/mysql/mysql.sock has 0.B
python script is:
import pyodbc
#pyodbc.pooling = False
conn = pyodbc.connect('DRIVER={MySQL};SOCKET=/var/lib/mysql/mysql.sock;UID=rooter;PWD=sshh')
csr = conn.cursor()
csr.execute("SET GLOBAL event_scheduler = ON")
csr.close()
conn.close()
del csr
I cant seem to connect with above script, Using isql i get Connected!

Comparing odbcinst.ini and your odbc.ini show an odd value for driver in odbc.ini, you should have a dynamic library here (I think).
And why don't you use direct mysql connection (without odbc)? :
import _mysql
conn = _mysql.connect(host="localhost", user="rooter",
password="sshh", db="mysql")
conn.query("SET GLOBAL event_scheduler = ON")
conn.close()
(not tested)

File "C:\Python26\lib\site-packages\MySQLdb__init__.py", line 19, in
import _mysql
ImportError: DLL load failed: %1 is not a valid Win32 application.
if Python26 && windows
we need download 3 files : libguide40.dll, libmmd.dll, libmySQL.dll
put the 3 files to C:\Python26\Lib\site-packages
and also put the 3 files to C:\Windows\system32
then restart your system
if Python27 && windows
when you setup the module ,be careful the version
MySQL-python-1.2.3.win32-py2.7.exe
MySQL-python-1.2.4.win32-py2.7.exe
one of the 2 version is you need

source: http://mysql-python.sourceforge.net/MySQLdb.html#some-mysql-examples
code tested:
import _mysql
conn=_mysql.connect(host="localhost", user="root", passwd="***", db="test")
conn.query("select * from test_table")
result = conn.use_result()
print result.fetch_row()
The fetch_row() function has two parameters:
maxrows limits the max number of rows returned.
how: it returns a tuple when how=0 and returns a dictionary when how=1.
For example, result.fetch(maxrows=5, how=1) returns an array (maximum size: 5) of dictionaries where the key is the column name and the value is the column value.
