Unable to Execute Query - Access Database 2016

Help
1

Hi There,
I am trying to execute an access query and when I configure the connection with connection wizard, it says that the connect is successful but while executing query, it gives me an exception. And in the output, it says " : ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"

I have already installed the Access Database Engine and tried both 32bit and 64bit but no help !

Below is the log :

"An error has occured

Hello,

I’ve been there, can you double check the data base you are querying has the same columns?
you know like a double check of everything, also are you running on admin mode?

here it´s a workflow with the insert query and all the files. :slight_smile:

Thanks for quick response @beesheep.

I am trying to fetch data from Access 2016 and when I configure connection, it says “Test Succeeded” but gives the above mentioned error while executing query.

@beesheep, I’m waiting to see if @AryanPrakash had any luck with that too :slight_smile:

I’m using OleDb instead of ODBC, maybe that would work?
See richard.denton’s post for a connection string.
It works fine for me with Access 2016. My first thought was like yours, I think, that it was a column name spelled wrong - that’s the same type of error I get when I name the column incorrectly in the query.

I am wondering if the type of installation of the oledb is not the one causing the problem.

@beesheep, I’m not having any trouble with the connector, just having trouble remembering to type in my column names correctly from time to time :slight_smile:
My thought was that OleDB might work instead of ODBC for @AryanPrakash.
