mORMot + MS SQL Server + FireDAC + JSON

Would you show me a demo sample for the subject matter?  I have tried to code a program below but always show error message "Project ORM_MTT.exe raised exception class ESQLite3Exception with message 'no such table: LTN_DTL'." in debug mode when I connect to server with browser url="http://127.0.0.1/root/LTN_DTL".  The content in browser only shows below lines:

{
"ErrorCode":400,
"ErrorText":"Bad Request"
}

But I have tested that the server itself could query the table records from my MS SQL server with TSQLDBFireDACConnectionProperties and export them to a JSON file sucessfully.

Below is my source code:

    //Conn: TSQLDBConnection;
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}


{ TForm1 }

procedure TForm1.btnQuitClick(Sender: TObject);
begin
  Close;
end;

procedure TForm1.FormCreate(Sender: TObject);
var download: RawByteString;
begin

  Props := TSQLDBFireDACConnectionProperties.Create(FIREDAC_PROVIDER[dMSSQL]+'?CreateDatabase=No;Server=tcp:192.168.1.4,1433','sunnyORM','sa','1111'); 

  Model := TSQLModel.Create([TSQLLTN_DTL],'root');

  VirtualTableExternalRegister(Model,TSQLLTN_DTL,Props,'LTN_DTL');

  DBServer := TSQLRestServerDB.Create(Model,':memory:',false);

  HttpServer := TSQLHttpServer.Create('80',[DBServer],'+',useHttpApiRegisteringURI);

  HttpServer.AccessControlAllowOrigin := '*'; 
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
  HttpServer.Free;
  DBServer.Free;
  Model.Free;
end;

procedure TForm1.FormShow(Sender: TObject);
begin
  if DBServer=nil then
    Close;
end;

end.

Please help !

Thanks in advance

Re: mORMot + MS SQL Server + FireDAC + JSON

I suppose a good call to DBServer.CreateMissingTable just after DBServer initialization would do the trick.
(as stated by the doc and the samples)

AFAIK a "Props.Free" may be also missing in your OnDestroy event.

And do not use "real" as type in Delphi.
This is deprecated since Turbo Pascal days.
Use directly "double" instead.

Re: mORMot + MS SQL Server + FireDAC + JSON

Thanks for your fast reply,

I have followed your steps but Mormot give me the following result:


TSQLLTN_DTL: unable to create external missing field dbo.LTN_DTL.NO - SQL="ALTER TABLE dbo.LTN_DTL ADD NO nvarchar(max)"


I don't know how to solve this case, my solution is MSSQL(back-end server)  + Mormot(App Server)(JSON) + Web browser to retrieve JSON data(Client side), it is common for REST application, I believe Mormot must be able do that, please point me to success !

Re: mORMot + MS SQL Server + FireDAC + JSON

I suppose because NO is a SQL reserved word.
So it can't be used as a column name.

Re: mORMot + MS SQL Server + FireDAC + JSON

Hi,

I  have change the field name to "NUMBER" yet, but still the same error message:

TSQLLTN_DTL: unable to create external missing field dbo.LTN_DTL.NUMBER - SQL="ALTER TABLE dbo.LTN_DTL ADD NUMBER nvarchar(max)"

May I send you the project with database for your reference?

Thanks!

Re: mORMot + MS SQL Server + FireDAC + JSON

I'm not a MS SQL expert.
Did the CREATE TABLE work as expected?
I wonder why the ALTER TABLE did not work.
Could you try to find out the expected syntax? Perhaps there is something particular with MS SQL.

You should better also specify a maximum column size for the RawUTF8 field, using "index 40" for instance if your number is 40 characters wide at most.
By default, a plain RawUTF8 create a nvarchar(max) which is a CLOB which will be much slower to access than a nvarchar(40) for instance.

Re: mORMot + MS SQL Server + FireDAC + JSON

Thanks for your reply.

Sorry, I mean I have a stable table sitting in MS SQL server.  Thus I have remarked this line "DBServer.CreateMissingTables(0);".

Now, the server program starts up with showing logs on console.  But when I connect to the server progrm with browser with URL= http://127.0.0.1/root/LTN_DTL.  The below error persists on console:

EXC    ESQLite3Exception ("no such table: LTN_DTL") at stack trace API 00614AC8 0040A44C
res    null
srvr    GET root/LTN_TL ERROR=400 (Bad Request)


Our existing table structure (with Data) as shown below:

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[LTN_DTL](
    [NUMBER] [nvarchar](10) NULL,
    [LX] [float] NULL,
    [LY] [float] NULL,
    [TE] [datetime] NULL,
PRIMARY KEY CLUSTERED
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO


Thanks!

Re: mORMot + MS SQL Server + FireDAC + JSON

Could you see in the logs (enable them first if needed) what are the SQL Statements sent to MS SQL?

Re: mORMot + MS SQL Server + FireDAC + JSON

Could you try with SynOleDB or SYnOdbc instead of Firedac?

Are you using latest nightly 1.18 version of mORMot?

Re: mORMot + MS SQL Server + FireDAC + JSON

Please, provide sources for TSQLLTN_DTL. Is any field named Number inside? Number is Reserved word - newer give property nemes equal to reserved words. Hope it help.

Re: mORMot + MS SQL Server + FireDAC + JSON

The source for TSQLLTN_DTL is as follows, no field is named as NUMBER.

  TSQLLTN_DTL = class(TSQLRecord)
  public
    fNO: RawUTF8;
    fLAT: real;
  published
    property NO: RawUTF8 read fNO write fNO;
    property LAT: real read fLATITUDE write fLAT;
  end;
