The Qt OCI plugin supports connecting to Oracle database as determined by the version of the instant client used.
libmysql.dll additionally needs the MSVC runtime libraries which can be installed with vcredist.exe QOCI for the Oracle Call Interface (OCI) It must be placed in the same folder as the application executable. When you distribute your application, remember to include libmysql.dll / libmariadb.dll in your installation package. Qt -cmake -G Ninja \Src\qtbase\src\plugins\sqldrivers -DCMAKE_INSTALL_PREFIX = \ -DMySQL_INCLUDE_DIR = "C:\mysql-8.0.22-win圆4\include" -DMySQL_LIBRARY = "C:\mysql-8.0.22-win圆4\lib\libmysql.lib" Tell qt-cmake where to find the MySQL / MariaDB header files and shared libraries (here it is assumed that MySQL / MariaDB is installed in /usr/local) and build:
Mysql connectorj library install#
Depending on your Linux distribution, you may need to install a package which is usually called "mysql-devel" or "mariadb-devel". You need the MySQL / MariaDB header files, as well as the shared library libmysqlclient.

How to Build the QMYSQL Plugin on Unix and macOS Please refer to the MySQL documentation, chapter "libmysqld, the Embedded MySQL Server Library" for more information about the MySQL embedded server. This can be done by adding -DMySQL_LIBRARY=libmysqld. To use the embedded MySQL server, simply link the Qt plugin to libmysqld instead of libmysqlclient. With the embedded MySQL server, a MySQL server is not required to use MySQL functionality. The MySQL embedded server is a drop-in replacement for the normal client library. Note: and are variables local to the current connection and will not be affected by queries sent from another host or connection. For example, you can do this as follows, to locate MySQL: this is required for PostgreSQL and SQLite). You should prefer this method if module needs to set properties for the provided target libraries (e.g. In some cases it's more convenient to use CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH variables to locate required libraries.
This is especially useful if the package provides its own set of system libraries that should not be recognized by the build routine.
Mysql connectorj library drivers#
When you configure drivers in the manner described above, CMake skips any dependency checks and uses the provided paths as is. I restarted my Python 2.7 GUI and re-ran my program and the library loaded correctly.C:\ Qt\ 6.0.0\Src\configure. It immediately recognised my 64-bit version of Python 2.7 and installed perfectly. I eventually found one here:ĭownloaded it, and ran it. The problem was that I was running a 64-bit version of Python 2.7 so I needed to go and find a 64-bit MySQLdb library. So I went to :Īnd downloaded the MySQL-python-1.2.4b4.win32-py2.7.exe, and again it didn’t work. When it finished installing I tried again. So I logged in to my Oracle account and went toĪnd downloaded the MySQL Connector/Python Windows MSI Installer for Python 2.7. When I tried to run the Wiki Scrape I received this error:
When you write a Python program to interact with your MySQL database you need to include the following library: import MySQLdbĭoing this without properly installing the MySQLdb library to the correct version of Python will result in the following error when running the program: No module named MySQLdb
