Data nodes are the core feature of Integration & Automation. They operate on app-generated data to produce different execution results. Data retrieval nodes fall into two types: single-record retrieval nodes and multi-record retrieval nodes. This article explains how to use them.

​
Single-Record Retrieval Node

  1. Sign in to the YiDA workbench and click My Apps.
  2. Select the app you need and go to the App Settings page.
  3. Click Integration & Automation, select an existing integration & automation flow, and click Edit.
  4. Move the cursor to the connection line of an approval node. A + button appears. Click + and select the Get Single Record node.
  5. Select a data retrieval method. Data can be retrieved from the following sources.
1

Configure data filter conditions. You can select all data or filter by conditions.

2

Configure sorting rules.

If multiple records match, the first record after filtering is returned based on the sorting rules.
Three options are supported: ascending, descending, and no sorting.
  1. When configuration is complete, click Save.

​
Multi-Record Retrieval Node

The multi-record retrieval node works much like the single-record retrieval node. The only difference is that a single-record retrieval node returns just one record, while a multi-record retrieval node returns multiple records.

​
Notes

Keep the following in mind when using data retrieval nodes:
  • If a single-record retrieval node matches multiple records, the first record after filtering is returned based on the configured sorting rules.
  • A multi-record retrieval node can retrieve up to 2,000 records at a time. (The Dedicated edition supports up to 2,000 records per retrieval; other editions support up to 100.)
