databooster / dbwebapi Goto Github PK

Hi,

Great Project by the way.
I am having a bit of an issue, where I am trying to pass null to a mandatory SP parameter.
However, I am receiving Exception:

Value cannot be null. Parameter name: DynamicPropertyNameOfColumn0

Is there a solution to this problem? Please note I cannot change the Stored Proc.

Thank you for this excellent project.

Hi ,

I found clients hangs on with out ConfigureAwait(false). Once i add this(ConfigureAwait(false), it works fine. thought , it will help full to you to modify the code.

Thanks
Sam

#if WEB_API2
protected async Task ExecAsAsync(string requestUri, IDictionary<string, object> inputParameters, CancellationToken cancellationToken) where T : class
{
HttpResponseMessage httpResponse = await ExecRawAsync(requestUri, inputParameters, cancellationToken).ConfigureAwait(false);
return httpResponse.ReadAs();
}
#else

Hi,

Just wondering, can we get result,if i can only pass view name instead of stored procedure name?

Hi, I am using TVP for bulk insert in my SP, following to the example in wiki I found always there is error message ""The type of column 'Comparer' is not supported. The type is 'IEqualityComparer`1'"

Here is my SP
Create Procedure [dbo].[Gatewaypayment_PCD_test ]
(@inGroupID int, @inTvpCategories dbo.CategoryTableType READONLY)

as
insert into Gatewaypayment_CTTest(CategoryID,Weight,CategoryName)
select ct.CategoryID, ct.Weight, ct.CategoryName from @inTvpCategories as ct

My Table and Type Table
CREATE TYPE dbo.CategoryTableType AS TABLE
( CategoryID int, Weight float(6), CategoryName nvarchar(50) )

CREATE table Gatewaypayment_CTTest
(CategoryID int, Weight float(6), CategoryName nvarchar(50))

Here is my json request
{
"inGroupID": 108,
"inTvpCategories": [
{
"CategoryID": 1,
"Weight": 0.15,
"CategoryName": "Peach Blossom"
}
]
}

Here are full error message response

Please Help,

Many Thanks.

I want to use dbwebapi in my website but navigating a web page url results in an error saying the stored procedure does not exist.

I am trying to pass a JS data array through to the server for bulk insertion but I receive an deserialize error. See the details/examples below.

Javascript Array Construction

I am constructing my JS array as follows:

var dataParams = [];
// foreach item...
dataParams.push({
                ID1: 1,
                ID2: 2,
                Value: 'xyz'
            });

$.getDb(url, dataParams, function(response){
   /// do something
});

ERROR

I receive this error in .Net:

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' 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.

How we can pass cancellation token to controller to cancel long running process.

Hi when I send GUID to the stored procedure I get error:
Failed to convert parameter value from a String to a Guid.
