Amazonka.DataPipeline.EvaluateExpression
Description
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.
Synopsis
- data EvaluateExpression = EvaluateExpression' {
- pipelineId :: Text
- objectId :: Text
- expression :: Text
- newEvaluateExpression :: Text -> Text -> Text -> EvaluateExpression
- evaluateExpression_pipelineId :: Lens' EvaluateExpression Text
- evaluateExpression_objectId :: Lens' EvaluateExpression Text
- evaluateExpression_expression :: Lens' EvaluateExpression Text
- data EvaluateExpressionResponse = EvaluateExpressionResponse' {}
- newEvaluateExpressionResponse :: Int -> Text -> EvaluateExpressionResponse
- evaluateExpressionResponse_httpStatus :: Lens' EvaluateExpressionResponse Int
- evaluateExpressionResponse_evaluatedExpression :: Lens' EvaluateExpressionResponse Text
Creating a Request

Create a value of EvaluateExpression with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:pipelineId:EvaluateExpression', evaluateExpression_pipelineId - The ID of the pipeline.
$sel:objectId:EvaluateExpression', evaluateExpression_objectId - The ID of the object.
$sel:expression:EvaluateExpression', evaluateExpression_expression - The expression to evaluate.
Request Lenses
evaluateExpression_pipelineId :: Lens' EvaluateExpression Text Source #
