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:

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.

When you configure drivers in the manner described above, CMake skips any dependency checks and uses the provided paths as is.
The way to allow two or more statements to be grouped into a transaction is to disable the auto-commit mode.C:\ Qt\ 6.0.0\Src\configure. In almost all cases, however, a statement is completed, and therefore committed, right after it is executed.)
A statement is completed when all of its result sets and update counts have been retrieved. (To be more precise, the default is for a SQL statement to be committed when it is completed, not when it is executed. This means that each individual SQL statement is treated as a transaction and is automatically committed right after it is executed. When a connection is created, it is in auto-commit mode. Using Transactions to Preserve Data Integrity.A transaction is a set of one or more statements that is executed as a unit, so either all of the statements are executed, or none of the statements is executed. The way to be sure that either both actions occur or neither action occurs is to use a transaction. However, the amount sold per week and the total amount sold should be updated at the same time otherwise, the data will be inconsistent. For example, when the proprietor of The Coffee Break updates the amount of coffee sold each week, the proprietor will also want to update the total amount sold to date. There are times when you do not want one statement to take effect unless another one completes.
