Network.AWS.DataPipeline.EvaluateExpression

Task runners call EvaluateExpression to evaluate a string in the context of the specified object. For example, a task runner can evaluate SQL queries stored in Amazon S3.

Creating a Request

evaluateExpression

Arguments

:: Text

eePipelineId

-> Text

eeObjectId

-> Text

eeExpression

-> EvaluateExpression

Creates a value of EvaluateExpression with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• eePipelineId - The ID of the pipeline.
• eeObjectId - The ID of the object.
• eeExpression - The expression to evaluate.

data EvaluateExpression

Contains the parameters for EvaluateExpression.

See: evaluateExpression smart constructor.
