// ```
// params[0] -> "sql query"
// params[1] -> column_type
// params[2] -> "column_name"
// ...
// params[n-1] -> column_type

// is a type available in the `WalletDb` API as an enum called `QueryType`. If a row
// is not found, the returned result will be a JSON-RPC error.
// NOTE: This is obviously vulnerable to SQL injection. Open to interesting solutions.
