Working with Nodejs + MSSQL on Linux / Ubuntu

Question

I have a nodejs application connected to an MSSQL server that works fine on my windows laptop sing mssql @npm

The same application cannot see the database on my Ubuntu laptop.

I defined the mssql link in Ubuntu as shown below, am I missing something?

• Updated ~ / .profile file as:

  ~$ export ODBCINI=/etc/odbc.ini
  ~$ export ODBCSYSINI=/etc
  ~$ export FREETDSCONF=/etc/freetds/freetds.conf

2. Exit the laptop to activate it, and the profile has been updated.

3. The necessary connection packages are installed.

  ~$ sudo apt-get install unixodbc unixodbc-dev freetds-dev sqsh tdsodbc -y

4. Configured FreeTDS

  ~$ sudo gedit /etc/freetds/freetds.conf

   [ACUMENSERVER]
   host = 192.168.0.10
   port = 1433
   tds version = 7.0

5. A FreeTDS connection with sqsh has been tested and it works fine:

  ~$ sqsh -S ACUMENSERVER -U mssql-username -P mssql-password

6. Configured ODBC - odbcinst.ini:

  ~$ sudo gedit /etc/odbcinst.ini

     [FreeTDS]
     Description     = TDS driver (Sybase/MS SQL)
     Driver          = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
     Setup           = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
     CPTimeout       =
     CPReuse         =
     FileUsage       = 1

7. Configured ODBC - odbc.ini:

~$ sudo gedit /etc/odbc.ini

   [ACUMENSERVER]
      Driver          = FreeTDS
      Description     = ODBC connection via FreeTDS
      Trace           = No
      Servername      = ACUMENSERVER
      Database        = myDataBase

8. Tested ODBC connection with isql and it works fine:

isql -v ACUMENSERVER mssql-username mssql-passward

nodejs ( Windows), Ubuntu, , , :

{ name: 'ConnectionError',
  message: 'Failed to connect to ACUMENSERVER:1433 - getaddrinfo ENOTFOUND',
  code: 'ESOCKET' }

1 Instal mssql:

npm install mssql

2 index.js:

var sql = require('mssql');

var config = {
    user: 'sa',
    password: 'sql@123',
//  server: 'myServername',  --> Not Working
//  server: 'ACUMENSERVER',  --> Not Working
    server: '6192.168.0.10', // WORKED
    database: 'myDB'
}

sql.connect(config).then(function() { 
// Query 

new sql.Request().query('select top 1 itemcode from OITM').then(function(recordset) {
    console.dir(recordset);
    }).catch(function(err) {console.log(err); /* ... query error checks ... */ });


// Stored Procedure 

new sql.Request()
    .input('input_parameter', sql.Int, value)
    .output('output_parameter', sql.VarChar(50))
    .execute('procedure_name').then(function(recordset) {
         console.dir(recordset);
     }).catch(function(err) {console.log(err); /* ... execute error checks ... */ });



}).catch(function(err) {console.log(err); /* ... connect error checks ... */ });
