Delete the Dataset

This endpoint is for deleting the dataset of a given dataset id

Query:

curl -i -X DELETE -H "Authorization: Bearer <token>" http://localhost:9090/api/1.0/datasets/<dataset_id>
Parameter Comments
dataset_id Dataset id to delete

It will remove all accessible dataset with taking the dataset id as a parameter.

Query:

curl -i -X DELETE -H "Authorization: Bearer <token>" http://localhost:9090/api/1.0/datasets?name=<dataset_name_url_encoded>
Parameter Comments
dataset_name_url_encoded  Dataset name to delete

It will remove all accessible datasets by taking the same dataset name for that user as a parameter.

Example:

For the dataset delete endpoint which accepts the name, since the name is not unique, there might be multiple datasets with the same name. In this case, we will return code 400 (Bad Request) and show the following message:

{
"message":"More than one dataset with matching name: Copy of Test Save. Please add \"force=true\" to remove all or append the dataset ID to remove a specific one.",
"datasets":[
{
"id":140060,
"datasetName":"Copy of Test Save",
"userId":786,
"username":"anhvo@cloud9charts.com",
"name":"Anh Vo"
},
{
"id":140063,
"datasetName":"Copy of Test Save",
"userId":27566,
"username":"anh@cloud9charts.com",
"name":"anhvo@cloud9charts.com"
}
]
}

Add the parameter “force” which can be set to true to delete all datasets with the same name.

If you pass in “force=true”, the success message will look for example:

curl -i -X DELETE -H "Authorization: Bearer e0Z3DIqtdurha2gzeqMKXg2Kvf4ipY5Sl13JrolDoOrwie" 'http://localhost:9090/api/1.0/datasets?name=Copy%20of%20Test%20Save&force=true'

Note: These 2 endpoints will delete all widgets (if still linked to the dataset) and disable the query as well.
