[英]Passing values from parent pipeline to child pipeline in Azure Data Factory
I'm pretty sure this is simple, but I can't seem to find this anywhere. 我敢肯定这很简单,但是我似乎在任何地方都找不到。 I created a parameter in a parent pipeline (say the pipeline name is TestParent) in data factory:
我在数据工厂的父管道(例如管道名称为TestParent)中创建了一个参数:
This parent pipeline invokes a child pipeline.
该父管道调用子管道。 I want to reference this parameter in the child pipeline.
我想在子管道中引用此参数。 What is the syntax to get the value of this parameter from the parent in the child?
从子级的父级获取此参数的值的语法是什么?
OK I finally got this to work: 好了,我终于有了这个工作:
I completely removed the parameter from the parent pipeline. 我从父管道中完全删除了该参数。 In the child pipeline (which is called HubMaster) we create a parameter called MasterBatchId:
在子管道(称为HubMaster)中,我们创建一个称为MasterBatchId的参数:
In the parent pipeline I created an Execute pipeline node called EP_HubMaster that calls a child pipeline called HubMaster. 在父管道中,我创建了一个名为EP_HubMaster的执行管道节点,该节点调用了一个称为HubMaster的子管道。 In order to populate the child pipeline parameter MasterBatchId at run time, we need to edit the JSON of the parent pipeline to look like this:
为了在运行时填充子管道参数MasterBatchId,我们需要编辑父管道的JSON,如下所示:
{
"name": "TestParent",
"properties": {
"activities": [
{
"name": "EP_HubMaster",
"type": "ExecutePipeline",
"typeProperties": {
"pipeline": {
"referenceName": "HubMaster",
"type": "PipelineReference"
},
"parameters": {
"MasterBatchId": {
"value": "@pipeline().RunId",
"type": "Expression"
}
}
}
}
],
"folder": {
"name": "Master"
}
},
"type": "Microsoft.DataFactory/factories/pipelines"
}
You can see that we pass the @pipeline().RunId
from the parent (which was the original intent) to the input parameter of MasterBatchId
in the child pipeline. 您可以看到我们将
@pipeline().RunId
从父级(原始意图)传递给子级管道中MasterBatchId
的输入参数。
