4. How to use

Here’s an example of how to use "Invoke Method" to merge the values of two data tables.

*In this example, we will merge data from one data table ("addRateData") into another data table ("rateTable") created with "Build Data Table" .Please also refer to the "Merge Data Table" knowledge base.

Data Table "dt1"
Created as "rateTable," but referred to as "dt1" in this example.

Data Table to Merge "dt2"
Created as "addRateData," but referred to as "dt2" in this example.

First, drag and drop "Core" > "Data Table" > "Build Data Table" onto the designer panel, and set the data table (contents of "dt1").

In the Properties, under "Output" > "Data Table," enter a variable of DataTable type (in this example, "dt1").
Refer to "Creating Variables" for more information.

Drag and drop "Core" > "Data Table" > "Build Data Table" again to set up the data table (contents of "dt2") and enter a DataTable variable (in this example, "dt2") under "Output" > "Data Table."

Next, drag and drop "System" > "Primitives" > "Invoke Method" onto the designer panel.

In Properties, under "Other" > "Parameters," click the "..." button.

In the pop-up window, enter the parameters and click "OK."
In this example, set "Direction: Input," "Type: DataTable," and "Value: dt2."

Enter the values in "Other" > "Method Name" and "Target Object" properties (in this example, "Merge" and "dt1," respectively).

Drag and drop "Core" > "Data Table" > "Output Data Table" onto the designer panel.

In Properties, under "Output" > "Text," enter a variable of String type (in this example, "result"), and in "Input" > "Data Table," enter a DataTable variable (in this example, "dt1").

To confirm the execution result, place a "Write Line" activity and set the necessary variables, such as "result" in this example.

Click "Home > Start" or press "F5" to run the workflow, then open the output panel to verify that the data from "dt1" and "dt2" has been merged and displayed.
