const result = await replicateQueryRecordsetAsView(
  {
    sourceType: 'sql',
    sourceSql: `SELECT w.workOrderNumber,
        w.workOrderDate,
        w.workOrderDescription, s.workOrderStatus
      FROM WorkOrders w
      LEFT JOIN WorkOrderStatuses s
        ON w.workOrderStatusId = s.workOrderStatusId
      WHERE year(w.workOrderDate) = @yearParameter`,
    sourceParameters: {
      yearParameter: new Date().getFullYear()
    },
    sourceDatabase: {
      server: 'productionServer',
      user: 'user',
      password: 'p@ssword',
      database: 'WorkOrderSystem'
    }
  },
  {
    destinationViewName: 'WorkOrdersThisYear',

      server: 'devServer',
      user: 'devUser',
      password: 'passw0rd',
      database: 'TestDB'
    },
    dropOldTables: true
  }
)

console.log(result)

/*
  {
    success: true,
    destinationRows: 1337,
    destinationTableName: '_WorkOrdersThisYear_1729614386783'
