(Required) Value to convert.


Convert basic types to strings

string(v: true)
// Returns "true"

string(v: 1m)
// Returns "1m"

string(v: 2021-01-01T00:00:00Z)
// Returns "2021-01-01T00:00:00Z"

string(v: 10.12)
// Returns "10.12"

Convert all values in a column to strings

If converting the _value column to string types, use toString(). If converting columns other than _value, use map() to iterate over each row and string() to covert a column value to a string type.

    |> map(fn: (r) => ({r with exampleCol: string(v: r.exampleCol)}))
