ddl_rewriter.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ddl_rewriter.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AppInstaller.exe - to follow. These files were created so that multiple programs (eg. MySQL Database Server) could share the same ddl_rewriter.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when ddl_rewriter.dll is attempted to be loaded either when MySQL Database Server is starting up, or in some cases already running. Some of the most common ddl_rewriter.dll errors include:
- Access Violation at address - ddl_rewriter.dll.
- ddl_rewriter.dll could not be found.
- Cannot find C:\Program Files\MySQL\MySQL Server 8.0\lib\plugin\ddl_rewriter.dll.
- Cannot register ddl_rewriter.dll.
- Cannot start MySQL Database Server. A required component is missing: ddl_rewriter.dll. Please install MySQL Database Server again.
- Failed to load ddl_rewriter.dll.
- The application has failed to start because ddl_rewriter.dll was not found.
- The file ddl_rewriter.dll is missing or corrupt.
- This application failed to start because ddl_rewriter.dll was not found. Re-installing the application may fix this problem.
Your ddl_rewriter.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MySQL Database Server), or deleted by a malware infection. Furthermore, ddl_rewriter.dll file corruption could be caused from a power outage when loading MySQL Database Server, system crash while loading ddl_rewriter.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
