# NEXT


Returns a new column, where each value represents a value that is *n* rows later in the source column. 

**Parameters**
+ `sourceColumn` – The name of an existing column.
+ `numRows` – A value that represents *n* rows earlier in the source column. For example, if `numRows` is 3, then `NEXT` uses the third-next `sourceColumn` value as the new `targetColumn` value.
+ `targetColumn` – A name for the newly created column.

**Example**

        "Parameters": {
            "numRows": "1",
            "sourceColumn": "age",

        }
    }
}
