Error c1083 QtSql
-
Your code compiled fine for me.
i had to remove the
Qtdatabase: i;
from login.h
as its not needed and was also wrong syntax.
Should have been QSqlDatabase i;
But You dont need to keep the database around as doc says.You really should study the Documentation as @SGaist says.
Without overall understanding of how the SQL system works, it will be hard
on you to do anything useful. -
@mrjj
I just put this as an example.
but even if you remove this line of code it gives error@123456789 What error?

@123456789 Show us Screenshot of .pro file.
i think you did not write in your .pro file.
if not then add it as below:QT += sql //Case-Sensitive

@123456789 How did you install Qt?

@123456789 After adding sql in your pro file: did you rerun qmake?
You should try following:- Delete build directory
- Run qmake
- Build
Also: why did you install 2 MinGW versions?

@123456789
Separate the code, put in next line QT += sql in .pro file,
Save all,
Close the qt project,
go to project file location,
delete ex3.pro.user,
open ex3 project,
Choose appropriate kit when configure project,
rebuild the project.
