Cannot Load Dynamic Library Libmysqldll Sql Manager


Cannot Load Dynamic Library Libmysqldll Sql Manager




If you are trying to connect to a MySQL database using DBExpress in Delphi, you may encounter an error message like this: "Failure to Connect : Unable to load libmysql.dll" or "[FireDAC] [Phys] [MySQL]-314. Cannot load vendor library [libmysql.dll or libmysqld.dll]. Hint check it is in the PATH or application EXE directories, and has x86 bitness." This article will explain the possible causes and solutions for this problem.


What is libmysql.dll?




libmysql.dll is a dynamic link library (DLL) file that contains the client library for MySQL, which is used by applications that communicate with MySQL servers. It provides functions for connecting, querying, and managing data in MySQL databases. libmysqld.dll is a similar DLL file that contains the embedded server library for MySQL, which is used by applications that run their own MySQL server instance.

Why does the error occur?




The error occurs when the application cannot find or load the libmysql.dll or libmysqld.dll file. There are several possible reasons for this:


  • The libmysql.dll or libmysqld.dll file is missing from the application directory or the system PATH.



  • The libmysql.dll or libmysqld.dll file is incompatible with the MySQL server version or the application architecture (x86 or x64).
