从 NodeJs 读取访问数据库

Question

Problem

I need to access the data of an access database (*.mdb). The approach should be written in nodejs and be used by multiple users that should NOT be required to make any changes to the ODBC drivers list in Windows.

Approaches

I've found the node-odbc . Looking at the documentation following snippet should work just fine:

const db = require('odbc');

const cn = `Provider=Microsoft.Jet.OLEDB.12.0;Data Source=C:\\Users\\some\\Dev\\db.mdb`;

db.connect(cn, (err, connection) => {
    if (err) {
        console.error(err);
    }
    console.log(connection);
});

Unfortunately is this the output I get:

[Error: [odbc] Error connecting to the database] {
  odbcErrors: [
    {
      state: 'IM002',
      code: 0,
      message: '[Microsoft][ODBC Driver Manager] The DSN could not be found and' +
        'there was no default driver specified'
    }
  ]
}
null

Answer 1

I found another package called node-adodb . The following snippet works just fine for me with a password protected database. Furthremore fixes this package the difference between x64 and x86 by using the SysWOW64 cscripts.exe file.

const adodb = require('node-adodb');

const cn = 'Provider=Microsoft.Jet.OLEDB.4.0;Data Source=db.mdb;Jet OLEDB:Database Password=MyPassword;';

const connection = adodb.open(cn);

connection.query("SELECT name FROM users WHERE firstname='John';").then((data) => {
    console.log(data);
}).catch(err => {
    console.error(JSON.stringify(err))
});
