Unable to connect to mssql server from qt application in ubuntu 20.04
Sql server located in windows 7
The connection is definitely present, because it was possible to connect through DDbeaver.
Can anyone help me in this situation?
Code:
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC3");
db.setConnectOptions();
QString serverName = "566***";
QString ipName = "tcp:192.168.144.101,1433";
QString dbName = "St***";
QString connectionString = QString("DRIVER={ODBC Driver 18 for SQL Server};Server=%1;Database=%2;").arg(ipName).arg(dbName);
db.setDatabaseName(connectionString);
db.setUserName("sa");
db.setPassword("top123TOP");
if (db.open())
{
qDebug() << "Correct connection";
}
else
{
QString error = db.lastError().text();
qDebug() << error;
}
otuput is:

We have a real old SQL server out there . The SQL Server show's version 10.50.2550.0, i think it's SQL Server 2008 R2. I had to use TLSv1 to connect to the server. I also had to do a "systemctl restart apache2" to get it to take affect. TLSv1.1 did not work with my MSSQL server version.
Error message: Connection failed: SQLSTATE[08001]: [Microsoft][ODBC Driver 17 for SQL Server]SSL Provider: [error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol]Database Connection Error

Not 100% sure why i had to restart apache2 for it to take effect, but I had to.

I'm trying to monitor my oracle db with zabbix by ODBC. My database version is 11.2 and I have the DB name, port, login and the password.
What I did until now is:
1- installed oracle instant client-basic, devel, sqlplus and odbc (all 11.2 version)
2- installed unixodbc and unix odbc-devel
and I configured some files:
/etc/oracle/tnsnames.ora
MY.DB.NAME =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = {i put my db host ip}) (PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = MY.DB.NAME)
)
)
/etc/odbc.ini
[MY.DB.NAME]
Driver = OracleDriver
Server = {my db host ip}
User = dbuser
Password = db123
Port= 1521
Database = MY.DB.NAME
/etc/odbcinst.ini
[OracleDriver]
Description = Oracle ODBC driver for Oracle 11g
Driver=/usr/lib/oracle/11.2/client64/lib/libsqora.so.11.1
And I did some exports:
export ORACLE_HOME=/usr/lib/oracle/11.2/client64/lib;
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME;
export TNS_ADMIN=/etc/oracle;
I want to test my connection with isql command, but when I try:
isql MY.DB.NAME
I receive this error message. I've never do this before, I followed many tutorials but I'm lost
Solved!!!
I am trying to connect with a local SQL Server database using the Python framework 'pyodbc' in an Ubuntu machine. But I get over and over the same error.
As background I have to add that I first createn locally a database with the 'sqlcmd' application and it works good in the terminal. I can access by this way.
sqlcmd -S 127.0.0.1 -U SA
But when I try access by Python scrip and I get the error.
Here is my code:
import pyodbc
details = {
'server' : '127.0.0.1',
'database' : 'testDB',
'username' : 'SA',
'password' : 'password'
}
connect_string = 'DRIVER={{ODBC Driver 17 for SQL Server}};SERVER={server};PORT=1443; DATABASE={database};UID={username};PWD={password})'.format(**details)
connection = pyodbc.connect(connect_string)
print(connection)
This is a simple code to star working with the framework, however I got the next error output in jupyter notebook:
InterfaceError: ('28000', "[28000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Login failed for user 'SA'. (18456) (SQLDriverConnect)")
Solved!!
driver = "ODBC Driver 17 for SQL Server"
server = "127.0.0.1"
database = "testDB"
username = "sa"
password = "pwd"
print ("'DRIVER={" + str (driver) + "};SERVER=" + str (server) + ";DATABASE=" + str (database) + ";UID=" + str (username) + ";PWD=" + str (password) + "'")
import pyodbc
conn = pyodbc.connect ('DRIVER={ODBC Driver 17 for SQL Server};SERVER=127.0.0.1;DATABASE=testDB;UID=sa;PWD=pwd')
getcon = conn.cursor ()
print ("Connected to Database!")
Now with this syntax works!!
while trying to connect to remort mssql server by command

In your odbc.ini file change 'Servername = ' to 'Server = '. Then remove the UID, PWD and ReadOnly lines from that file temporarily. You may want to remove them altogether and pass in the credentials from your application.
Then, be sure that your MSSQL DB is allowing connections through port 1433, that SQL Server is not blocking the incoming server's IP address, and that you have the correct password.
Also, if that doesn't work, review these troubleshooting instructions:
I'm trying to connect to a database on my host machine (windows xp, sql server 05). My guest machine is Ubuntu 10.04. I can connect and execute commands with tsql, but isql fails. Below are my config files and error messages.

The issue was this line in odbc.ini
Servername = 192.168.163.1
It should have been SQLEXPRESS which I think points to the name of the server configured in freetds.conf
