Rust SDK - db.query().bind() depends on query type

[rgeber]

Hi

I'm experimenting with the Rust SDK and noticed an unexpected behaviour.

The following example code as provided by the documentation works:

let response = db.query("CREATE user SET name = $name")
    .bind(("name", "John Doe"))
    .await?;

Replace the query with a DEFINE query I get an error:

    let response = db
        .query("DEFINE NAMESPACE $name")
        .bind(("name", "testspace"))
        .await?;

The error looks as follow:

Error: SurrealDBError { source: Db(InvalidQuery(RenderedError { text: "Failed to parse query at line 1 column 18 expected an identifier", snippets: [Snippet { source: "DEFINE NAMESPACE $name", truncation: None, location: Location { line: 1, column: 18 }, offset: 17, explain: None }] })) }

I'm not excluding the possibility that this is by design. Hence I did not yet file a bug report.

Could you please explain why this change in query makes a difference? Is this a wanted result or does this warrant a bug report?

Even if this behaviour is correct a more clear error message (e.g. This statment is not supported) or a note in the documentation should make it more clear.

Thanks a lot for clarification.

Hi Roman,

Yes, this is a current limitation of the define statement. There is a feature request for this #1911.

Thank you very much for pointing me to the issue. Will keep an eye on it and work around the problem for now :)
