Working with Update Record Process
Process Purpose
The Update Record process is used to update records from a table of a remote database in a specific Host server.
The remote database profile you create within MCL-Designer V4 is responsible for the direct communication between your MCL-Designer project and a remote database.
Once the project is loaded into a device, that same profile can be used to allow communication between the device and the remote database/host server, via MCL-Net. Therefore, make sure that the connection string of the selected profile includes an OLE DB provider that is compatible with the intended remote database. Ex: If you intend to use an Oracle database, select a remote database profile with the corresponding driver Microsoft OLE DB for Oracle Provider.
When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the Update Record process. This properties window includes three tabs - "General", "Query" and "Advanced".
If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.
