ODBC connection on an D365 on-Premise

Hi
 
We do have a D365 on-premise installation and need to connect to an external Database to read and write data over classes.
How can I create ODBC connections in an on-prem installation?

    Hi Navaneeth
     
    No I did not try the Marketplace thing but I did exactly the same in my code. And as mentioned in Dynamics AX2012 it works so I don't think the error is in the code but maybe in the settings on the DSN OR something on server side to block it

    Hi Cembrit,
     
    For ODBC Connection with D365 FO there is a Visual studio marketplace add-on that is available. Have you tried this?
     
    In the above code all you need to do is setup an ODBC Connection on the On-Premise D365 FO Machine and then add that connection string in the code highlighted in the connection string. Create a parameter for the connection string in the D365 FO system and fetch the connection string through X++ Code.

    MaxTokenSize is set to maximum and from Dynamics AX2012 it works fine. Only from D365FO on-prem not

    Hi @Cembrit,

    Means the SQL Server computer was unable to process the client login packet. This may be because the packet was created improperly or because the packet was damaged during transmission. It can also be caused by the configuration of the SQL Server computer.

    As per Microsoft documentation, to resolve this problem, increase the MaxTokenSize value of the server computer, to a size large enough to contain the largest token of any user in your organization.
    Please find below documentation :

    Yes I found the option after I posted here but then I get
     
    The login packet used to open the connection is structurally invalid; the connection has been closed. Please contact the vendor of the client library.

    Thx I did that but do you have any idea how to setup the DSN than. Normally I would set it up with "integrated windows authentication" but if I do so I get an error :
    Microsoft][ODBC Driver 17 for SQL Server]SSL Provider: The certificate chain was issued by an authority that is not trusted.
    [Microsoft][ODBC Driver 17 for SQL Server]Client unable to establish connection

    Sorry to come back to this post but I do not find any option in D365FO to setup a DB connector 
    WIll it be possible to write SQL Statements like  
    SQL ="SELECT [accountid],[accountnumber],[ap_AccountTypeName],[ap_Categoryidname],[ap_crmaccountid],[ap_ResponsibleidName],[name],[OwningBusinessUnit] "
        + "FROM [EDW].[CRM].[CRM365_Account] CRM365Acc "
        + "where not exists ("
        + "select * from  [EDW].[CRM].[CRM365AX_Account] CRM365AXAcc "
        + "where CRM365AXAcc.accountid = CRM365Acc.[accountid]) "
        + "AND CRM365Acc.[ap_AccountTypeName] = 'Customer'";
    I really have no clue how to solve this in D365FO (on-premise)
