!!! warning
    This task is currently deprecated and will be removed in future versions.

## Inputs

| Name            | Data Type | Values | Description                             |
|-----------------|-----------|--------|-----------------------------------------|
| customDataTypes | `any`     |        | Supply the dataTypes to create by input |
| Activate        | `any`     | Yes    | Activates the task                      |

## Outputs

| Name    | Data Type | Values | Description                                     |
|---------|-----------|--------|-------------------------------------------------|
| rawData | `any`     |        | The created DataTypes                           |
| Success | `Boolean` |        | Result of the method execution                  |

On the *Custom Data Types* Tab, you have entries for each of the result parameters of the command:

## Behavior

The task should be activated before connecting to the driver (onInitialize -> activate task -> connect). Custom DataType names don't need to end with `DataType` because this suffix will be automatically appended to each name. DataTypes can be inserted using settings or by input. Input value overrides settings values.

## Remarks

None.
