#1 mORMot 1 » Create a Restmodel from an existing Oracle database Schema » 2017-02-06 23:38:36

Hello,

I 'm newbie in the mormot world, and I successfully tried some samples, that I modified to work with Oracle in native OCI mode.
everything works well and I m impressed by the response time!!!!
my questions are the following:

1/ How to retrieve a global existing database and create the corresponding RestModel.  I tried SynDBExplorer and manually select some tables then it asks me to manage the joined file.
After I  generates thru the "To Object" button the Type model. seems to be work,  but I don't see see how it manages the joined information requested previously .
Maybe it s not the right way to generate a whole database to use SynDBExplorer ?


2/ I 'd like to publish this RestModel, as  a  webservice CRUD  to get or post Data in Json format. This is for external tool such as mobile application , or html5 + JS app wants to collect
and update datas . what is the best way or which sample can I use to derive from.

3/ In each Tsqlrecord, can i add some validation rules. So what is the best way , do we have some classes provided with the framework?


Thank for all  your  recommendation

hello,

I am newbie in Mormot and every day discover, the power of this framework. Today I d like to do some authentification,
but i have my own tables for Group and User already created in Oracle. These tables are maintained thru my own application.

The Idea  is to be able at the init or starting of the server , to download an image of my securities in the mpormot tables
and then use the authentification thru TSQLRestServerFullMemory.
i don't know if it s the right approach.
some samples could be helpfull

thanks

Nope. finally i get errors when trying to connect.
I'd like to connect directly to my database without any tnsname.
But even the tnsnames is defines i get errors.
for instance my  tnsnames.ora is as below
lsp45=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 54.85.217.118)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = DFCASB)
    )
  )

I am tying the sample 16 (client server). when executing the clientexe, I get the following results:
- server = lsp45
- database= blank or DFCASB

please explain me more in detail what do you think about. thanks
Use a shared PropsOracle := TSQLDBOracleConnectionProperties property, and call PropsOracle.NewThreadSafeStatementPrepared() within your methods services.

hello,

1/ I am trying to connect to oracle and call a procedure with 2 parameters.
IN and OUT.  if the parameter out is a string or rawutf I get the following message when call the procedure at the statement ExecutePrepared.
When it's integer It works well.
I debug it on the PL/SQL side and the procedure is correctly excuted, but seems that the VARCHAR2 is not allocated.

Exception classe ESQLDBOracle with message TSQLDBORACLEstatement error ORA-06502: character string buffer too small

here some sub-set of code

 PropsOracle := TSQLDBOracleConnectionProperties.Create('DB','SID','USER','PWD');
  call:='select actcode,actnom,actid from acteur where actcode like ''AK0%''';
  query := 'BEGIN MYPROCEDURE(?, ?); END;';
  stmt := PropsOracle.NewThreadSafeStatementPrepared(query, false);
  stmt.BindTextS(1, call, paramIn); // call var string;
  stmt.BindTextS(2, res, paramOut); // res var string
  stmt.ExecutePrepared;

for information my procedure is declared as:

PROCEDURE MYPROCEDURE(   call              IN       varchar2,    retn             OUT     varchar2);

2/ General question:
I am newbie in mormot and I see that there is a lot of different  possibilities to create servers.
My first wish is to start a project able to reply to REST request from http.
so something like a console  server multi-thread based on the http.sys
in detail :
- start a basic authentification
- create a session oracle
- call procedure and get results (varchar, integer, no cursor)
. select , ... statements
.
.
. then close my session.

for the first time I don't want to use ORM possibilities. I will see later.
so I am looking for some piece of code or example, where I can  rely on .
anyway I love very much the Mormot concept.


thanks for your help

I am really sorry, but i did a mistake in the settings.
I used :TSQLDBOracleConnectionProperties.Create(//ip-address:port,'SID','USER','PWD');  and get the issue.
but when using
TSQLDBOracleConnectionProperties.Create('TNSDEF','SID','USER','PWD'); it works well.

thanks
