Difference between $select and select query parameter

Question

In Graph Explorer I'm testing select query parameter to return all properties and webDavUrl property

GET /v1.0/drives/{driveId}/items/{itemId}?$select=webDavUrl  

select without $

GET /v1.0/drives/{driveId}/items/{itemId}?select=webDavUrl   
GET /v1.0/drives/{driveId}/items/{itemId}?select=*,webDavUrl  

return webDavUrl property.

But

GET /v1.0/drives/{driveId}/items/{itemId}?$select=*,webDavUrl  

doesn't return webDavUrl property.

Is this some expected behavior or a bug?

Hi @Macháček Martin ,

As per documentation query-parameters,
On the /beta endpoint, the $ prefix is optional. For example, instead of $filter, you can use filter. On the v1 endpoint, the $ prefix is optional for only a subset of APIs. For simplicity, always include $ if using the v1 endpoint.

Hence the same is applicable to select query parameter, $select is recommended to use for v1.

Hope this helps.
