Solved Is it not possible to open M.S. access file?
-
@hskoglund
i tried absolute filepath also but i am getting the same error -
I see. Did you use double backslashes?
-
@hskoglund
yes i tried with double backslashes and also with forward slashes. but same error -
Hmm, create a folder called MyFolder on your C: , copy your Database1.accdb file into it and try:
db.setDatabaseName("Driver=Microsoft Access Driver (*.mdb, *.accdb); DBQ=C:\\MyFolder\\Database1.accdb;";
-
Also, did you VERIFY that odbc is available and working ?
https://www.isunshare.com/windows-10/5-ways-to-open-odbc-data-source-administrator-in-windows-10.htmlThis might not be related to Qt at all.
If you never worked with ODBC before, please study a bit

I tried what you suggested but getting the same error.
Yes the odbc is available and wroking.
and i just access the the file locally not via any server my file is in the same computer where i am writing the code -
Hi, I googled a bit and found this thread
So if you do not have Microsoft Office installed you need to download the driver for MS Access .accdb files
-
Indeed you must install the Access ODBC driver. The driver is independent from installed Office !
(Be aware Windows like to kill this driver after windows-update. So you must reinstall it sometimes.)Then you must look in the ODBC tool from windows to find out the correct driver name. This is the correct for me (is not the same as you use):
"DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};" -
i already tried downloaded and intalled the drivers, even though i have M.S Office installed on my computer. But getting the same error.

Hi @rockon209
which Qt Version do you use? -
@Andy314
I am using Qt 5.7.0 -
Hi @rockon209
the QtCompany had the idea to do not distribute the binarys for the ODBC driver anymore. That was in Version 5.5 and 5.6 I think. I initiated a discussion about it. The result was that the driver should be integrated again. I dont know if this is in 5.7 really the case.Look if you have in the path like C:\Qt2\5.6\msvc2015\plugins\sqldrivers
the qsqlodbc files. -
yes the file is present in the path.

Hello @rockon209,
oh I am happy :-)Now your Problem:
It must work ! I use it since 1 year.We must find the error systhematic.
First you should try a connection via the windows Windows-ODBC tool.
I there is something wrong we must not look on Qt. -
@Andy314
How to do that bcoz i new to this database access. I dont know how it works. Could you help me? -
Hi @rockon209
Search in Windows for "ODBC".
Open the Program, dont know the english name. Something like "ODBC-Datasource 32-bit"
Tabpage Drivers: Is there a entry like Microsoft Access Driver (*.mdb, *.accdb) ?more later...
-
Hi.
Perhaps, you have a very minor problem.
Compare the connection strings below.db.setDatabaseName("Driver={Microsoft Access Driver(*.mdb, *.accdb)}; DBQ=C:/MyFolder/Database1.accdb;"); // It's not OK!
db.setDatabaseName("Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=C:/MyFolder/Database1.accdb;"); // It's OK!
The ODBC driver is installed by default on Windows.

Jup, use exactly the name shown in the ODBC tool !!!!!

Thank you very much.
