You need to get the MySQL installation files. I use follwing code Qt Code: Set the SYBASE environment variable to point to the directory where you installed the client library and execute qmake:. If the compilation of a plugin succeeds but it cannot be loaded, make sure that the following requirements are met:. Write database security policy. When a database is added see QSqlDatabase:: Thanks for this tutorial, it seems to be great!

Are you using the correct compiler? With Microsoft SQL Server the result set returned by a stored procedure that uses the return statement, or returns multiple result sets, will be accessible only if you set the query’s forward only mode to forward using QSqlQuery:: 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.
We will need this to compile the QT MySql driver: SQLite minor releases sometimes break file format forward compatibility. The configure script cannot detect the neccessary wmysql and include files if they are not in the standard paths, so it may be necessary to specify these paths using the -I and -L command-line options.
Hi, thank u for this tutorial, but have error, please help enrike enrike: Because of this i must compile it new. Hi, maybe I’m just look in the totally wrong place, but I cannot find the second Qt file you use.
If the file does not exist, SQLite will try to create it. I am receiving the following when I run mingwmake: If the plugin is built with an older version, then forward-only mode will not be available – calling QSqlQuery:: Also I want to add that on step 3, you can also move the mysql. This will be required by QT to compile the MySql driver.
I had to recompile qsqlmysql, and it started working after that. Due to the practicalities of dealing with external dependencies, only the SQLite3 plugin is shipped with binary builds of Qt. I can see a libmysql.
To use full path, you can do so cd C: Just took a look at the URL bukld posted, it seems to be in the ‘single’ folder. The Qt SQLite 2 plugin is offered for compatibility. These libraries are responsible for the low-level communication with the DBMS. For reference, my sizes qsqlmysql.
Build Mysql plugin for Qt
In that nuild, only queries in forwardOnly mode can be used successfully. Thanks for sharing the info. It also means you’ll need to tweak the. 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, bkild you will get a lot of “undefined symbols” errors.

Build QMYSQL & QSQLITE database drivers on Debian GNU/Linux
Whenever possible, use the qmusql 3 plugin instead. It is recommended that you use unixODBC. By default, the Microsoft library is used on Windows. Run configure -help to see what drivers can be built. Enabling foreign key support from underlying SQLite add: To check which drivers are available run this program.
