Hi there!

New to CT, but worked a lot in Delphi, so the style of coding is not a mistery to me..., I connected to Firebird (piece of cake) and Postgres (simple as can be), but I couldn't connect to MS SQL Server 2014 or any other version.

Can you provide me with a tutorial or step-by-step or something to allow me to connect? Working on Win 10-64, MSSQLS 2014, CT 6.3.

Thanks Sir
Did you try to connect to your MS SQL server with
Database Desktop tool ?
with SQLDB direct or
with ODBC ?

pl_ZeosDBO is the next option to connect with a MSSQL Server

"KontoID" varchar(8) NOT NULL,
"Konto" varchar(100) NOT NULL,
"Analitika" char(1),
"KorDat" date,
"Korisnik" varchar(14),
CONSTRAINT "PK_Konto" PRIMARY KEY ("KontoID")
);

Hello Mr. Sternas,

Using CT 6.3 final, Database Desktop crashes both on 32-bit and 64-bit of TyphonIDE.
Crash occurs with either option (New Dictionary, new connection etc).

...and some questions... (thanks for the "sir" part ;) )

* Where I can find (or construct) dblib.dll ?
* Do you have any additional informaion regarding MS SQL conections?

Tried the solution, but as reported above, had an exception. Right now applied the solution and rebuilding the tools and Big IDE (I assume thats the correct building), when its done, I'll try and will be reporting any pending issue. Thanks in advance.

Thank you for your answer.
Unfortunately, the Database Desktop tool crashes when trying to create a new dictionary.

Thank you sir.

- Tried ntwdblib.dll, compiled fine and is detected right. The access violation also appears when the tool is compiled for dblib.dll.
- Both Typhon32 and Typhon64 expose the problem.

Using CT 6.30 final.

Replaced the CT6.30 one inside the source typhon package, rebuilt everything and it works great both 32 and 64 bit.
Thank you very much :)

is there also a fix for the error
Can not load DB-Lib client library "libsybdb.so". Check your installation.
Success

This is very annoying it seems this lib is for sybase, i am trying to connect to ms sql server
I am getting this from the IDE so I DO NOT WANT runtime solutions, I want this working in the IDE

If I am to switch from Delphi to CT than it should be working off course

This works for me:
// ftp://ftp.freepascal.org/pub/fpc/contrib/windows/dblib_1.3.zip
// put only these DLLs in exe ProgramDir: (make sure 64bit for 64bit exe . . .  just saying)
// dblib.dll 
// libiconv.dll


uses
  {$IFDEF UNIX}
  cthreads,
  {$ENDIF}
  Classes
  { you can add units after this },
  SysUtils,
  MSSQLConn,  sqldb, Generics.Collections;


procedure getSQLrow();
var
  AConnection  : TMSSQLConnection;//TSQLConnection;
  ATransaction : TSQLTransaction;
  Query        : TSQLQuery;

  aRow : TStringArray;
  i:integer ;
begin
  rowlist := TStringList.create;

  AConnection := TMSSQLConnection.create(nil);
  AConnection.Hostname := '192.168.0.100';
  AConnection.username := 'anuser';
  AConnection.Password := '123456';

  ATransaction := TSQLTransaction.Create(AConnection);
  AConnection.Transaction := ATransaction;
  AConnection.DatabaseName := 'andb';
  Query := TSQLQuery.Create(nil);

  Query.SQL.Text := 'SELECT ...... ;';

  aRow := [ 'row1','row2'];
 

  Query.Database := AConnection;
  Query.Open;
  while not Query.Eof do
  begin
   // etc  . . .
  

    Query.Next;
  end;
  Query.Close;
  AConnection.Close;
  Query.Free;
