Data Plane tables
Learn how to create an Alias Component that references existing tables in your Data Plane within Ascend Flows.
Prerequisites​
Before beginning, ensure you have:
- An Ascend project
- A Data Plane Connection
- Access to database tables you want to reference
Creating an Alias Component​
Create an Alias Component in two ways: using the Component form in the UI or directly in the file system.
- Form
- Files panel
- Double-click the Flow where you want to create your Component
- Right-click anywhere in the Flow Graph
- Hover over Create Component, then over Read in the expanded menu, and click Alias
- In the pop-up window, select your desired database and table
- Click Create Alias in the top right
- Complete the form with these details:
- Select your Flow
- Enter a descriptive Component Name like
read_sales
- Open the files panel in the top left corner
- Navigate to and select your desired Flow
- Right-click on the Components directory and choose New file
- Name your file with a descriptive name like
read_sales.yaml
and press enter - Add your YAML configuration using one of the formats below
Configuration options​
When creating an Alias Component, you have several configuration options depending on your needs.
Basic configuration​
To configure an Alias Component, directly specify the table location:
component:
alias:
location: "MY_DATABASE.MY_SCHEMA.MY_TABLE_NAME"
The location
field follows the standard database.schema.table
pattern to specify the table you want to reference.
Parameterized configuration​
For more flexibility across environments, use Parameters in your Alias Component:
component:
alias:
location: "${parameters.database}.${parameters.schema}.MY_TABLE_NAME"
This approach lets you define different database and schema values for different Environments without changing the Component definition. For example, you might have these Parameter values defined in your Profile:
parameters:
database: DEV_DB
schema: PUBLIC
See Parameters for more details on configuring and using Parameters.
Next steps​
After creating your Alias Component, you can:
- Connect it to a Transform Component to process the data
- Create data quality tests against your referenced table
- Write processed data to a destination
