Trying to access Firebird database

Recommended Posts

mjolnirmarkiv

Hi,

I'm trying to connect to Firebird database via AutoIt. Something that was supposed to be a cakewalk so far ended with no succes, as usual hoping for your help.

I'm using the following Firebird Direct Access for Visual Basic DLL: http://sourceforge.net/projects/fbdll4vb/files/. And the code below comes from Stephen Podhajecki (Eltorro) Firebird UDF (only parts I need at the moment):

Global $fb_dll = DllOpen ("fbdll4vb20.dll")

Firebird_ConnectDatabase ("C:\Program Files\AIT\Projetex 9\Projetex Server\Database\Projetex.fdb", "ODCB", "123")
If @error Then MsgBox (48, "Error", "Failed to login!" & @CRLF & "Error code: " & @error)
Firebird_DisconnectDatabase ()

Func Firebird_ConnectDatabase ($p_database, $p_username, $p_password)
  Local $connect_str = "char[%d];char[%d];char[%d]"

  $connect_str = StringFormat ($connect_str, StringLen ($p_database) + 1, StringLen ($p_username) + 1, StringLen ($p_password) + 1)

  Local $fb_struct = DllStructCreate ($connect_str)
  DllStructSetData ($fb_struct, 1, $p_database)
  DllStructSetData ($fb_struct, 2, $p_username)
  DllStructSetData ($fb_struct, 3, $p_password)

  Local $return = DllCall ($fb_dll, "int", "ConnectDatabase", _
                           "ptr", DllStructGetPtr ($fb_struct, 1), _
                           "ptr", DllStructGetPtr ($fb_struct, 2), _
                           "ptr", DllStructGetPtr ($fb_struct, 3))

  $fb_struct = 0

  Return SetError ($return[0] <> 0, 0, $return[0])
EndFunc

Func Firebird_DisconnectDatabase ()
  Local $return = DllCall ($fb_dll, "int", "DisconnectDatabase")
  Return SetError ($return[0] <> 0, 0, $return[0])
EndFunc

The code above gives me this:

The specific kind of server\database I need to connect to is belong to following application if that matters: http://www.projetex.com/, it is using Firebird 2.5. While ODBC\123 comes from following settings in the Server Administrator utility:

I've installed a VM with above mentioned application, server and databse running on it so I have admin rights to access it for testing. Nevertheless when I tried to use a gsec (a command prompt utility that comes with the app) to display a list of users it only gave me this:

gsec -user Admin -password admin -database "C:\Program Files\AIT\Projetex 9\Projetex Server\Database\Projetex.fdb" -display
use gsec -? to get help
Your user name and password are not defined. Ask your database administrator to setp up a Firebird login.
unable to open database.

So I changed it to ODBC, and there was some progress:

gsec -user ODBC -password 123 -database "C:\Program Files\AIT\Projetex 9\Projetex Server\Database\Projetex.fdb" -display
invalid request BLR at offset 37
table USERS is not defined

I tried to add a user mjolnir\123 and this time there was no progress:

gsec -user ODBC -password 123 -database "C:\Program Files\AIT\Projetex 9\Projetex Server\Database\Projetex.fdb" -add mjolnir -pw 123
An error occured while attempting to add the user.
invalid request BLR at offset 51
table USERS is not defined

It seems I'm not quite understand how the damn thing works. The Server Administrator utility have plenty of users including the admin, all of the have access to read the database and could do this via Projetex client, neither cann't do this nor via gsec, not programmaticlly via AutoIt code above. And then it says smth about "table USERS" which is not defined apparently, looks like database users is not the same thing as server users and I'm doing it wrong.

Are your %ProgramFiles% permissions restricted?

I have a system that needs to write to that folder and on some machines it can not.  You need Admin level access.

Try placing the .fdb in another folder? Or amend the Windows Security settings for that folder?  

Other RDBMS that store their database files in similar locations run into similar problems - also, while you are at it, check if McAfee is installed/blocking your access? Its notorious for blocking access to the %Temp% folder, which many db tools use to access files.

Thank you, Skysnake.

 

I have admin rights, so I can read\write from that location, no problem. No McAfee installed. As for the database relocation, it seems I cannot do it, at least legitimately via admin utility.

I played with my Firebird db over the weekend.  Do you have FlameRobin (or similar?) installed?  Have you defined users?  

I would suggest first just running a few SQL query tests in FlameRobin to see if it actually works before trying to access it with AutoIt.

      Here is a simple program that some of you might appreciate.
      It is a more full fleshed out version of something I worked on a while back as a proof of concept.
      I will just quote the information found in the Program Information dialog.

      INItoSQL DB.zip
      INItoSQL DB v1.1.zip  (see Post #3 for update details)
      Program requires the sqlite3.dll, not included, but easily enough obtained.
      I have also included the beginnings of a new UDF (SimpleSQL_UDF) I am working, which you can use with the included 'Check conversion.au3' file to check a resulting conversion ... just modify the values for a few variables to suit your situation.
      I've not yet gotten around to coding a testing/checking results script, so I recommend the following open source program, which I have been using for some time. It was here, but is now here at GitHub - DB Browser for SQLite

      Here is the bare bones of a UDF I have started work on.
      Mostly just a proof of concept at this stage, and still need to add some functions and dress the UDF up a bit ... to look like a UDF ... though it has my own distinct styling, especially as I have never really developed a UDF before now .... used plenty and modified plenty though. I've even invented my own UDF variable naming convention, which I am sure some of you will be aghast at. I work with what feels best for me, but others are free to adapt if they wish.
      The idea is to emulate the simplicity of INI files, but gain the benefits of SQL.
      Two scripts are provided.
      (1) The UDF, a work in progress - SimpleSQL_UDF.au3
      (2) An example or testing script - UDF_Test.au3
      Another first for me, is creating a 2D array from scratch, never done that before, that I can recall ... never had a need, and even for 1 dimension arrays, for a long time now, I have just used _StringSplit to create them. So I needed a bit of a refresher course, which my good buddy @TheDcoder assisted me with ... not without some angst I might add. LOL
      SimpleSQL_UDF.zip
      Program requires the sqlite3.dll, not included, but easily enough obtained.
      Hopefully the usage is self-evident ... just change the Job number variable in the UDF_Test.au3 file to check the existing functions out.
      Enjoy!
      P.S. This is also related to a new program I have just finished and uploaded - INItoSQL DB

      Only early days at this point, but I have been pondering such a program for a while.
      As good as calibre is (thank you Kovid Goyal), which is a great and wonderful ebook suite of tools and a fair database, it does have its limitations. One of which, is how it deals with multiple libraries, another is the views you get. CalibBrowser will seek to address those.
      What CalibBrowser is not going to be, is an editor for existing calibre libraries. That will be left up to calibre, which is very much needed still, and covers many aspects I will never look at. Unlike calibre, which is quite a complex program, CalibBrowser also seeks to be simple. It is mainly a viewer, at this point, but will later be able to create its own libraries. However, it does not and will not export them to calibre, especially as calibre employs a far different method and structure to what CalibBrowser will employ.
      When CalibBrowser starts, it looks for calibre executables and the main Calibre Library. Whatever isn't found, you get prompted for with a browse option.
      A calibre library, is a set of ebook folders (Author\Ebooks) and a database file, always named metadata.db, and which causes an issue when it comes to multiple libraries, but makes life a bit easier when reconstructing any corrupted libraries. However, there are better ways to deal with that, as my program will show.
      The metadata.db file is an SQL database, so I am having a learning curve right now, as I have only ever dealt with an SQL database previously, codewise, when I created my INItoSQL program some time last year, as an exercise to prove a point.
      At the moment, things are pretty basic, and not everything works 100%. Here is a screenshot, to give an idea of it, but keep in mind, I intend to expand the current GUI for other stuff I will be adding.

      Older Screenshots
      Gawd, I just noticed the '3|7' in the Book Input field (original screenshot). I was using that during troubleshooting for the multiple images scrolling and forgot to disable it ... not that it impacts anything. When it comes to maths, I struggle a bit, especially when tired. Right scrolling was easy, with a continuous loop, was easy to implement. Left scrolling was significantly harder for my poor brain ... until I realized I needed to see them as Min and Max.
      As you can see the program is usable, and all the buttons, aside from the Program Information one, work. You can even load different calibre libraries, and even reload after making changes to one with calibre. The calibre program does not need to be running, even to view an ebook in the Calibre Reader. The combo selector for a library and the ADD button are only temporarily placed where they are, until I expand the GUI.
      My intention at this point, is to add another five thumbnail images, directly below existing. Currently they aren't clickable, but I may add that.
      Here is another screenshot, of what you see when you click the larger Cover image.

      If you want to have a play with the program as is, then you will need to also get the 'sqlite3.dll' file from some online source. When CalibBrowser starts successfully with the selected calibre library, it copies its metadata.db file to a sub-folder of the program called 'Backups'. It also creates a sub-folder in that, based on the library name, to house it. That copied file, is the one the program uses, though it does not even edit that, and file modification is checked every time the program starts with a particular library, or when you Reload or select a library. If the original source file has been modified, then the program copy is overwritten. The Reload Database button does nothing, if there is no change detected, and reports such.
      Place the required 'sqlite3.dll' file in the CalibBrowser root folder. Download includes source files (sqlite3.dll excepted).
      Also required of course, is an install of calibre, plus some ebooks in a created library - Calibre Library is the default when you first add ebooks to calibre. The Mobile Read Forums, is a great source for all things ebook, and calibre can be found there in the E-Book Software section.
      CalibBrowser.zip  - Upload 4  (previous downloads: 1 + 12 + 5)
      My apologies for the program being created in AutoIt v3.3.0.0. It is the first one I have done in a while, with an older AutoIt version. Basically my Win 7 Netbook, which has a current version of AutoIt, was busy and is always busy doing something, and not suitable for doing big projects for several reasons. My older but more powerful Win XP Laptop, has a better programming environment, better computer chair (most important for my knees etc), better external monitor (wider and newish), full size external keyboard & mouse, and a great suite of setup tools to assist me. I run several older versions of AutoIt already on my Laptop, but haven't yet determined what I need to adjust to add a current version of AutoIt to the mix. This also applies to my hugely beneficial Toolbar For Any program (one of those tools), which I constantly use with SciTE. At some point, when finished, I may update the program to the current AutoIt version ... especially as I believe I am now proficient enough to do so, having become quite familiar with it in the last year or so, making many programs with it.
      Enjoy!

      Hello guys! 

      I am having some difficulty in achieving a very simple task here. I have gone through the forums and tried some examples and UDFs but I can't seem to work it out. I would really appreciate if someone could help me out. 

      Problem:

      Currently, I am logging the required feedback from the script into a log file in a simple way ... get the info in the var >> write it in the file 

      But now I am in need to perform some analysis and need some of the values to go into an MSSQL table  in the attached format
      Also, I need to be able to use Integrated Security" or "Trusted_Connection set as true or use the logged in windows credentials to connect to the server/database




      any help will be much appreciated!!!  

      Thanks!

      Hi all,
      I hope you can help me with this. I need to connect to a Database using Cloudera ODBC Driver for Impala. I installed the driver, created a User DSN (drona2) and tested it successfully (got the message: Successfully connected to data source!) but when I try to connect to the database using a Conneciton String, it simply didn't work.
      I tried connecting to the database using the User DSN, I previously created, that has all parameters needed but got the following error:
           $ProviderDatasource = 'DSN=drona2;'
           $conn_Database = ObjCreate ("ADODB.Connection")
           $conn_Database.ConnectionString = $ProviderDatasource
           $conn_Database.Open
           ==> The requested action with this object has failed.:
           $conn_Database.Open
           $conn_Database.Open^ ERROR
      Also I tried adding all parameters to my connection string as follows but also got the same error:
           $ProviderDatasource = 'Driver=Cloudera ODBC Driver for Impala;Host=MyHost.domain.com;PORT=21050;AuthMech=3;UID=MyUserId@domain.com;PWD=MyPasswordc;Schema=default;SSL=1;AllowSelfSignedCerts=1;AllowHostNameCNMismatch=1;CheckCertRevocation=1;KrbFQDN=_HOTS;KrbServiceName=impala;ServicePrincipalCanonicalization=1'
      I hope someone has used this driver successfully before and can shed some light here.
      If you need additional information, let me know.
      Regards,
