, rather than a compilation issue! Originally in the Run Environment of Qt, the LD_LIBRARY_PATH of qt4.8.6 is automatically set to/opt/qt4.8.6/lib and changed to/opt/qt4.8.6. the required dynamic library is actually in/opt/qt4.8.6/plugins/sqldrivers. The running environment of qt5.2.1 can run because the LD_LIBRARY_PATH of qt5.2.1 is automatically set to/usr/lib/x86_64-linux-gnu, and there is another qt4 directory under this directory, the libsqlite. so.

implementation. Atomity: Atomicity is implemented at the low-level, starting from StartTransaction and ending with CommitTransaction. Consistency: The Consistency is implemented at the statement level, that is, the middle layer. In addition, the updated xmin, xmax, cmin, and cmax in the tuple header provide the judgment basis for transaction visibility. Isolation: Initialize the transaction Isolation level during StartTransaction. Provides the foundation for creating snapshot for MVCC. Duarabil

) Through the above, we can find that the above lock keeps the statement hanging there. After the lock is completed, the application will soon run out. Then, check the application code and find that no two transactions are committed in the code. After adding the submit operation, re-run the number, and soon run. If you want to kill the statement, first confirm with the relevant personnel whether the statement is a key process. Killing Method: query the pid of the process on the mydb server of th
