Checking if a pipeline exists
We can check if a pipeline is available in the catalog by looking up its name.
Syntax
Check if a pipeline exists in the catalog:
CALL gds.pipeline.exists(pipelineName: String)
YIELD
pipelineName: String,
pipelineType: String,
exists: Boolean
Name | Type | Default | Optional | Description |
---|---|---|---|---|
pipelineName |
String |
|
no |
The name of a pipeline. |
Name | Type | Description |
---|---|---|
pipelineName |

String |
The type of the pipeline. |
exists |

Example
In this section we are going to demonstrate the usage of gds.pipeline.exists
.
To exemplify this, we create a node classification pipeline and check for its existence.
Creating a node classification training pipeline:
CALL gds.beta.pipeline.nodeClassification.create('pipe')
Check if a pipeline exists in the catalog:
CALL gds.pipeline.exists('pipe')
pipelineName | pipelineType | exists |
---|---|---|
"pipe" |
"Node classification training pipeline" |
true |
