Elementary Data Replication Module between Exact Online and Azure SQL Server

This articles guides you through the creation of an elementary application module on Invantive Cloud to replicate data from Exact Online to a table re-created in SQL Server every time the module is executed. Advanced and/or scheduled replication is available using Invantive Data Replicator and/or Invantive Data Hub.

Instructions

Prepare Database with Exact Online and SQL Server

Execute the following steps to create a (virtual) database which allows direct access to SQL Server and Exact Online:

  • Create a database with Exact Online as data container on https://cloud.invantive.com/app/setup/databases/new.
  • Open the database on Invantive Cloud.
  • Click on “Data Containers“.
  • Check that the Exact Online data container has alias “eol“.
  • Add a data container to the database using SQL Server.
  • Check that the SQL Server data container has alias “sqlserver“

Application module

Execute the following steps:

  • Create a new application on https://cloud.invantive.com/app/development/applications/new.
  • The name can be “Sample“ and description “Sample replication“.
  • Click on “Modules”.
  • Add a new module with code “EOL2SQLSERVER” and description “Replicate data from Exact Online to SQL Server“
  • The source code specifies that a HTML page is to be printed after copying the data from Exact to SQL Server:
declare
  l_output varchar2;
begin
  l_output := '';
  l_output := l_output || '<h2>Replicate</h2>';
  --
  -- Copy the Accounts from all Exact Online companies
  -- to the SQL Server database as a new table.
  --
  create or replace table eol_accounts@sqlserver
  as
  select *
  from   exactonlinerest..accountsbulk@eol
  ;
  --
  cloud_http.set_use_template(true);
  cloud_http.set_response_body_text(l_output);
end;

Execute Replication

Execute the following steps to execute the replication:

  • Go back to the new created application.
  • Click on “Execute“.
  • Choose the database you have created.
  • Click on “Execute“.
  • Click on the module.
  • After some time, depending on the amount of accounts in Exact Online, a HTML page is rendered.

Now check your SQL Server database and see the new table.

Execute Exact Online / SQL Server integration using Curl

The module can be executed interactively from Invantive Cloud. With App Online, you can also run the module using a browser or curl.

Execute the following steps to run the module:

  • Determine the URL to use on App Online as follows.
  • Run the application.
  • Choose the database.
  • Find the module you wish to run from App Online.
  • Select the link “Copy Link“ at the bottom right corner of the module.
  • The link is now on your clipboard.
  • Paste the link in a new browser window.
  • Enter your Bridge Online user and password (which is shared with App Online).
  • In case an authentication error occurs please ensure that on the database the correct IP addresses are whitelisted.

From curl, you can run the module using the following syntax:

curl \
  --basic \
  --user user...:password... \
  --output c:\temp\results.html \
  --url https://app-online.cloud/apps/.../databases/.../modules/.../

A more extensive sample using curl to retrieve data from Invantive Cloud is available at Pre-load data in OData-cache to avoid Power BI timeouts.
