When you use this function in a query, it adds a duplicate of the entry specified by the parameter values to the specified column in the specified dataset.

For more information on using query functions and operators in a REST API request, see Queries. For an end-to-end description of how to create a query, see Creating a Query.

The example below adds a duplicate of the second entry in the Region column of the earthquake dataset, whose {DATASET_ID} is 90af668484394fa782cc103409cafe39, to that column. The result creates a second instance of the string.

  "version": 0.3,
  "dataset": "90af668484394fa782cc103409cafe39",

        "fn": "repeat",

  "metrics": ["repeat"],
