[solinad21]

need json datasource and i have changed you index.js with this:

if (connections) {
    if (connections.driver === 'json') {
        this.command += ' -t ' + connections.driver
        this.command += ' --json-query ' + connections.jsonquery
        this.command += ' --data-file ' + connections.datafile
    } else {
        this.command += ' -t ' + connections.driver
        this.command += ' -H ' + connections.host
        this.command += ' -n ' + connections.database
        this.command += ' -u ' + connections.username

        // optional parameters
        if (connections.hasOwnProperty('password')) this.command += ' -p ' + connections.password
        if (connections.hasOwnProperty('port')) this.command += ' --db-port ' + connections.port
        if (connections.hasOwnProperty('sid')) this.command += ' --db-sid ' + connections.sid
    }
