Use Custom Parameters

Custom parameters in your queries offer a flexible way to introduce variables without directly modifying query parameters. This guide will walk you through creating, utilizing, and calling queries with custom parameters.

Adding Custom Parameters​

  1. Open the query panel and select the query you want to add custom parameters to.
  2. Navigate to the Parameters section in the top bar.
  3. Click the + button to add a custom parameter.
  4. For each parameter, specify:
    • Name: Identifier for the parameter.
    • Default value: A constant string, number, or object.

Syntax for Utilizing Parameters​

Use parameters.<identifier> in your query to employ custom parameters. Note that parameters can only be used within the query where they are defined.

How to: use custom parameters

Example: Create Row in ToolJetDB with Custom Parameters​

Let's assume we have a ToolJetDB table with the following columns: name, email, and contact. We will create a new row in the table using custom parameters.

  • Create a new ToolJetDB query, select a table from the dropdown and select the Create Row operation.

  • Add the following parameters:

    1. name: name and value: Shubh
    2. name: email and value: [email protected]
    3. name: contact and value: 4638563845
    How to: use custom parameters

  • Add the columns to the query and use the custom parameters to set the values.

    ColumnValue
    name{{parameters.name}}
    email{{parameters.email}}
    contact{{parameters.contact}}

  • Finally, execute the query to create a new row in the ToolJetDB table with the values provided in the custom parameters.

Example: Providing Custom Parameters Using Events​

In this example, we will demonstrate how to use custom parameters in a query by providing values from an event. We will use execute a REST API query and on its success, we will execute the ToolJetDB query to create a new row with the response data.

  1. Create a REST API Query:

    • Method: GET
    • URL: https://reqres.in/api/users?page=2

  2. Add a Success Event:

    • Name: onSuccess
    • Action: Run Query
    • Query: Create Row
    • Parameters: The parameters that you have added to the query will automatically be available in the event.
      1. name: {{queries.getSalesData.data.data[0].name}} This will use the name from the first record of the response data.
      2. email: {{queries.getSalesData.data.data[0].email}} This will use the email from the first record of the response data.
      3. contact: 4638563845 provided as a constant value just for demonstration.

  3. Execute the REST API query and observe the new row created in the ToolJetDB table.

Note: You can also use parameters in JavaScript queries. Learn more about JS Query Parameter.
