Set Operator

Overview

The Set operator lets Creators Also known as Unqork Users, or Designer Users; is anyone who is inside the Unqork platform. add new values to a data structure. Examples of how you can use a Set operator include:

• Creating a new key/value pair in an object.

• Creating new row(s) in a table.

• Adding new key/value pairs in a table row.

You'll find the Set operator in the Table group to the left of the Data Workflow canvas.

About the Info Window

Learn more about each setting in the Set operator's Info window:

Setting	Description
Category	Grayed out and non-adjustable setting indicating the operation type.
Label	Sets the label for your operator, displaying below the operator on your Data Workflow canvas. This field is optional, but set a label if you use more than one of the same operator type. A label helps you identify your operators without opening any Info windows.
Path	Enter the key of the key/value pair you want to create. If you add this key to a specific position in an existing array, it specifies the path to get that position. Use dot notation. For example, [0].name would create a key called name in the 0 index position.
Value	Enter the value for the key/value pair you want to create. You can leave the Value setting blank if you connect another data source to the Set operator's lower input port. No special formatting is required. If you set a string A string is an object that represents a sequence of characters. Strings typically hold data represented in text form., you do not need to add quotes around the value.

Input Port Functionality

There are two input ports on the left of the Set operator. Each input port provides a different function:

Upper Input Port

Connect the upper input port to connect to a data source. For example, an Input operator connected to a Data Table component could be the data source. Or, an Input operator could connect to a Create Table operator if you use the Set operator to create rows in a new table.

Lower Input Port

The lower input port connects data to add to your data source. The lower input port is optional as you can define data to add in the Set operator's Info window. However, you can only define simple values to add like a string A string is an object that represents a sequence of characters. Strings typically hold data represented in text form. or a number The Number data type accepts integer or floating point values. The number data type does not use quotes around numerical values., in the Info window. To add a more complex data structure, like an array An array is a type of object that stores one or more data types. Data types supported in arrays include numbers, strings, and objects. or object An object is a type of data structure that represents a single, self-contained entity that acts as a container for the characteristics of that entity., to an existing object, connect the array to the lower input port and the object to the upper input port.

The lower input port can also connect a Create Value operator. Instead of defining the value to add in the Set operator, you'll define the value in the Create Value operator. Enter a value in the Expression/Value field of the Create Value operator. Make sure to use the following formats: =string for strings, and =number for numbers. Then, connect the output port (right) of the Create Value operator to the lower input port (left) of the Set operator.

Configure the Set Operator

In this example, use the Set operator to create a key/value pair in an existing object An object is a type of data structure that represents a single, self-contained entity that acts as a container for the characteristics of that entity.. First, define an object in the Default Value field of a Hidden component. Then, use a JSON Parse operator in the Data Workflow to turn the JSON JSON (JavaScript Object Notation) is an open standard file and data interchange format. Unqork uses JSON for submission (record) data. into an object data structure.

Configure the Hidden Component

Use a Hidden component to create an object An object is a type of data structure that represents a single, self-contained entity that acts as a container for the characteristics of that entity. where you'll add a key/value pair.

1.

In the Module Builder, drag and drop a Hidden component onto your canvas.
