# XO0414: wire name no derive uses

A field's wire name (`name as "key": T`) is used only by `derive Json` and `derive SqlRow`. On a struct with neither it changes nothing. Add the derive, or remove the wire name. See core 2.2.

## Example

```xo
struct User {
  name as "Name": Str
}
```

## Fix

```xo
struct User {
  name as "Name": Str
} derive Json
```

Run `xo explain XO0414` for this text in a terminal, or see
[section 10.6 of the specification](../../spec/core/#106-diagnostic-codes).
