    @jsulm "here" meant the current PC in which i'm trying to get access to mysql database.
    And how can i check MySQL client Library whether it is missing or not?

    Thank you!

      @mvsri Does C:\Qt\Qt5.12.3\5.12.3\mingw73_64\plugins\sqldrivers\qsqlmysqld.dll exist?

          @mvsri I think you don't have MySQL connector installed on your PC ==> https://stackoverflow.com/questions/31821329/qmysql-driver-loading-error

          You have to download it from MySQL web site and install it

            @mvsri If it is working on the other PC then copy the MySQL client lib from there

                @KroMignon I have followed that steps earlier in other PC and it's working in it.
                But the problem is when i try this in my PC it doesn't work and the configuration of both PC's are same and even i tried copying mysql client lib from other PC to my PC and still it doesn't work

                  @mvsri said in MYSQL dll linking issue with QT in windows 10:

                  even i tried copying mysql client lib from other PC to my PC

                  Where / how did you copy it? And you should not distribute debug stuff (as qsqlmysqld.dll suggests you're doing)

                    I have uninstalled everything and reinstalled QT and MYSQL following every step which i did on other PC.
                    But still i have the same problem. i even checked the PATH everything is correct and i don't know where am i going wrong.

                      @mvsri Just to be sure every dependency is correctly set, can you try to check C:/Qt/Qt5.12.3/5.12.3/mingw73_64/plugins/sqldrivers/qsqlmysqld.dll with Dependency Walker ?
