The error can be reproduced when the InMemoryStorage provider is not available. Although the message is confusing, it signals that an error occurred during creation of the in memory table.
Please make sure that the InMemoryStorage provider is available and licensed. Some ways to do this:
Look at the list of available objects in the Query Tool of Invantive Control, it should list the InMemoryStorage provider as shown below:
Note that the Conversion provider is probably not available on your PC; it is only for complex data conversions between platforms.
Or query the availability using:
select *
from exactonlinerest..systemproviders
The resulting list should display it:
When not available please check which product you are using. With Invantive Control it should be available always (see Help -> License -> Components), but for instance with Invantive Query Tool it is not available. Use a product that has it and ensure your license includes it too.

How can I parse a JSON string that would cause illegal C# identifiers?

Cannot deserialize the JSON array (e.g. [1,2,3]) into type ' ' because type requires JSON object (e.g. {"name":"value"}) to deserialize correctly

The current code I have for this is the following:
Module Program
Sub Main(args As String())
dim json As string = File.ReadAllText("C:\Temp\cards.json")
dim result As cards = JsonConvert.DeserializeObject(Of cards)(json)
End Sub
End Module
Public Class cards
public property cards as list(of card)
End Class
Public Class card
public property faction as string
public property id as string
public property image as string
public property import_id as string
public property kredits as integer
public property rarity as string
<JsonProperty("set")>
public property cardset as string
public property type as string
End Class
I can deserialize just one of these on its own, however when I try and deserialize with both it fails due to the following:
Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'json_deserialize_test.cards' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
I have tried changing my deserialization to:
dim result As cards = JsonConvert.DeserializeObject(Of List(Of cards))(json)
but to no available, something that was mentioned in another question, can someone point me in the right direction here please, I feel like I've been looking at it too long and need another pair of eyes.
After migration from MSSQL to the MySql I faced this issue with some queries.
Packets - .Net 4.8, EF 6.4.4, MySql.Data 8.0.22, MySql.Data.EntityFramework 8.0.22
For example, this query with GroupBy statement caused NRE:
var finalActivities = from examActivity in activitiesFilteredForReport
orderby examActivity.CreateTime descending
group examActivity by axamActivity.CreateTime into gr
select gr.FirstOrDefault();
Exception StackTrace:

But if I write code like this:
var finalActivities = from examActivity in activitiesFilteredForReport
orderby examActivity.CreateTime descending
group examActivity by axamActivity.CreateTime into gr
select gr.FirstOrDefault().Id;
It gives me Ids without any exception.
In this case, I apply some workaround to make code work:
var ids = activitiesFilteredForReport.GroupBy(activity => activity.OrderExamId)
.Select(g => g.FirstOrDefault().Id);
var finalActivities = from examActivity in activitiesFilteredForReport
join id in ids on examActivity.Id equals id
orderby examActivity.CreateTime descending
select examActivity;
But I not sure is it a good solution. Can anyone help me to sort this issue? What I do wrong?
I'm trying to parse some YAML from a file and convert each item to a flat JSON object.
I'm having some issues with datasets where there are multiple / nested objects.
I'm failing to unmarshal multiple items per file.
I'm unsure how to get nested properties such has item -> description -> en
When I run the following code I get the error.
cannot unmarshal !!map into []item.Item
I think I've got to look into sub-types within my structure, but I can't seem to get anything to work.
Any help would be appreciated.
Code:
import (
"gopkg.in/yaml.v2"
"io/ioutil"
)
func parseItemYaml() {
filePath := "./typeIDs.yaml"
yamlFile, err := ioutil.ReadFile(filePath)
if err != nil {
log.Printf("yamlFile.Get err #%v ", err)
}
itemData := map[int][]Item{}
err = yaml.Unmarshal(yamlFile, &itemData)
if err != nil {
panic(err)
}
// Then convert to JSON
// Eventual persistance
}
Item Structure:
type Item struct {
ID int
Name string `yaml:"name"`
Description string `yaml:"description"`
GroupID int `yaml:"groupID"`
IconID int `yaml:"iconID"`
GraphicID int `yaml:"graphicID"`
MarketGroupID int `yaml:"marketGroupID"`
Mass float64 `yaml:"mass"`
Published bool `yaml:"published"`
Volume float64 `yaml:"volume"`
}
Desired JSON format:

"GroupID":72,
"IconID":112,
"GraphicID":72,

Make structs e.g. like this:
type Language struct {
De string `yaml:de`
En string `yaml:en`
Fr string `yaml:fr`
Ja string `yaml:ja`

Zh string `yaml:zh`
}

Also, as far as I see, it should be map[int]Item{} and not map[int][]Item{}.
I wrote a script that upload a xml file, look at the following code snippet:
open System.Xml
open System.IO
open System
type XmlErrorLoad =
| Success of XmlDocument
| FileNotFound of FileNotFoundException
| OtherException of Exception
let doc (filename:string) =
try
let file = XmlDocument()
file.Load(filename)
Success file
with
| :? FileNotFoundException as ex -> FileNotFound ex
| :? Exception as ex -> OtherException ex
let fileNotExists = doc("C:\Temp\ip2.xml")
match fileNotExists with
| Success s -> ()
| FileNotFound ex -> printfn "File not found: %s" ex.Message
| OtherException ex -> printfn "Exception: %s" ex.Message
In this case, ip2.xml file does not exist and it should throw an error FileNotFound and print on the screen.
"File not found: %s" ex.Message
But I've got the message

I need to convert this string

to a NSData object.
I used
NSData* data = [NSData dataWithBytes:[string cStringUsingEncoding:NSASCIIStringEncoding] length:[string lengthOfBytesUsingEncoding:NSASCIIStringEncoding]];
or
NSData* data =[data dataUsingEncoding:NSASCIIStringEncoding];
And then save data to a Core Data entity.
But when I read data from the entities the result is utf8 encoded.
"{
"name":"Tsubasa En La Liga",
"description":"Tếp sau bộ tsubasa El classico…anh đã trở lại, gặp lại những bạn bè và đối thủ cũ và cố gắng đưa đội tuyển nhật đoạt chiếc cúp vô địch"
}"
I don't want the string encoded to utf8.
I want the original string should be save to Core Data entity.
Thank you.
you can fix that by escaping your backslashes. use double back-slash \\.
