You should now have a screen where you can create a "service", i. Click on Edit and Add Service. To create a "service" you have to specify the type of connection or service, the network transport and the server machine ID. The default port number for Sybase server is ; separate the IP address and port number with a comma.
In the figure above the IP address of the machine I want to connect to is Notice the port number is also specified. When you click OK you should see defined a "service" that look like the figure below except with your server's IP address. We now need to ping the server to make sure our connection information is correct. If you get a message like the one below you will have to adjust a locale setting file; the message is saying that the LANG environmental variable on your machine is set to a value that does not appear in the locale data file.
However we can still ping with this error, but you will have other problems if you don't fix it. You may or may not have this problem, depending on what other software you have loaded on your machine. Select the "server" you created in steps and click on PING.
If you have configured the communications correctly and you can connect to your server you see a message box like the following. Now let's go correct the locale problem we saw in step 13; if you didn't see the error message box from step 13 skip this step and the next one. Note the value that is returned - in this figure the value is EN-US. You can use EPM or the system editor. The easiest way to do this is to copy the first line in the [OS2] section and change the value to what your LANG setting is.
We are almost done with the client part. Usually this problem is caused because a later or earlier version DLL packaged with one of the applications that uses the DLLs will overwrite an earlier or later version and cause the application needing the other version to break.
DLL name conflicts are where completely unrelated DLL's from two different vendors just happen to have the same name.
If there happens to be another DLL with the same name in some directory specified in the LIBPATH before the directory that contains the DLL your application wants, it will get loaded instead of the one intended and you will get an SYS error message: can't load the program segment.
This is because the function or other programmy thingy needed by the application is not in the DLL that was loaded by the system - it was the wrong DLL! This solution will not always work though, and the Sybase client is an example of when that technique will not work. Plus some applications, e. Now lets check and make sure the renamed DLL stuff works and that we can execute something that exercises the client library before we setup ODBC.
Start it with: isql -Usa -P -S mrlinux where mrlinux represents the name of the "server" you defined in step 9. You have to specify the type of connection or service, the network transport and the server machine ID.
The -U parameter specifies the user ID, the -P parameter specifies the password, the -S parameter specifies the server to connect to. In the example we give we are using the default system administrator user ID of sa , which has no password.
If you are connecting to an established Sybase system the sa user ID may not exist, or may have a different password. You should use the user ID and password assigned to you by the system administrator. On the next line type go and press Enter. You should see data if you are connected correctly. I have found the Intersolv version 2. EXE program to install the driver; see last month's article for info on where to get the driver and how to install it.
The modified versions of L2SYB Select the Sybase driver from the list. Fill in the settings on the Setup page. The server name is the name you used when you created a named "server" in step 9 above. The database name is the database on that server you want to connect to. Pubs3 is a sample database included on the Sybase distribution CD. If you do not specify a name you will connect to the Master database on the server.
The figure below shows data from the authors table from the pubs3 sample database in Lotus Approach. Each part must be downloaded separately and installed separately. I doubt seriously if it installs on a regular Window 3.
ZIP which is an image of the Sybase Windows 3. The SybWin Make a directory on your hard drive where you want the Windows client to live. Unzip the SybWin My folder looks like this. If the file does not exist, SQLite will try to create it. SQLite also supports in-memory and temporary databases. Simply pass respectively ":memory:" or an empty string as the database name. SQLite has some restrictions regarding multiple users and multiple transactions.
This is due to SQLite associating the type of a value with the value itself rather than with the column it is stored in. A consequence of this is that the type returned by QSqlField::type only indicates the field's recommended type. No assumption of the actual type should be made from this and the type of the individual values should be checked.
The driver is locked for updates while a select is executed. SQLite version 3 is included as a third-party library within Qt. It can be built by passing the -qt-sqlite parameter to the configure script. If you do not want to use the SQLite library included with Qt, you can pass -system-sqlite to the configure script to use the SQLite libraries of the operating system. This is recommended whenever possible, as it reduces the installation size and removes one component for which you need to track security advisories.
However the needed implementation must be provided by the user. For better performance the regular expressions are cached internally. By default the cache size is 25, but it can be changed through the option's value.
SQLite minor releases sometimes break file format forward compatibility. For example, SQLite 3. Please refer to the SQLite documentation and change logs for information about file format compatibility between versions. Patch releases are therefore both backward and forward compatible. To force SQLite to use a specific file format, it is necessary to build and ship your own database plugin with your own SQLite library as illustrated above.
The database file must exist before a connection can be established. Firebird must be used with a server configuration. Note that InterBase requires you to specify the full path to the database file, no matter whether it is stored locally or on another server.
Please use Firebird or the free edition of InterBase. Note that if the text encoding set when connecting to the database is not the same as in the database, problems with transliteration might arise. You should always use client libraries that have been compiled with the same compiler as you are using for your project.
If you cannot get a source distibution to compile the client libraries yourself, you must make sure that the pre-compiled library is compatible with your compiler, otherwise you will get a lot of "undefined symbols" errors.
Some compilers have tools to convert libraries, e. If the compilation of a plugin succeeds but it cannot be loaded, make sure that the following requirements are met:.
Make sure you have followed the guide to Deploying Plugins. QSqlDatabase is responsible for loading and managing database driver plugins. QSqlDriver is responsible for connecting to a database, establish the proper environment, etc. QSqlDatabase forwards many of its function calls directly to QSqlDriver which provides the concrete implementation. QSqlResult is responsible for sending queries to the database, returning result data, etc. QSqlQuery forwards many of its function calls directly to QSqlResult which provides the concrete implementation.
When implementing a Qt SQL driver, both of these classes must to be subclassed and the abstract virtual methods in each class must be implemented. Read How to Create Qt Plugins for more information on this. Documentation contributions included herein are the copyrights of their respective owners.

In reply to this post by Torsten Bergmann. After installing all and getting things sorted, it rejects my connection. Alain Rastoul Hi Sebastian,. Cant remember why I switched to 2. Then use this name for the connection in Smalltalk. If the connection fails try with a database viewer tool first.
In detail:. Use a new Pharo 3. Install "OSWindows" from config browser. Authentication depends on installation. Usually one uses the SQL Server authentication, either with. After login you should be able to select the database and test connection right in the ODBC control panel Go back to Pharo and run some query: con results Transcript open.
MyTable' execute. Try the query with a database tool first. Hope this helps. The same for me : About Glorp, it is a really nice piece of code, but has some drawbacks like all orms : IIRC, there is a "global" object cache and Glorp manage object's locking conflicts in addition to Sql locking imho bad.
ORM is perfect for quick and simple queries but tend to write bad queries when complex. Wonderful Torsten, thanks so much for that. Hi guys, there is a project that needs to connect and extend a system using SQLServer and Pharo is being considered for the backend. The MS recommendations for client connectivity to Sql server is not to use native libraries but instead use a "standard" layer. In detail: 1.
