Which ODBC driver version is used by FireDac

[Die Holländer 34]

Sometimes my users get an SQL error maybe because the computer doesn't have the proper

ODBC driver version installed. (Like "ODBC Driver 17 for SQL server")

 

How in runTime can I ask FireDac to fetch this driver version used by the application?

I have the FDConnection open.

I can't get the name like "ODBC Driver 17 for SQL server" but I see things like "17" by the statement under, so that will do..

 

Uses FireDAC.Phys.ODBCWrapper;

SQLDriverName:=TODBCConnection(DatabaseConnectionObject.ADConnection.CliObj).DRIVER_NAME;//DRIVER_VER;// DRIVER_ODBC_VER;

TFDPhysMSSQLDriverLink has an ODBCDriver property, I have no server to test it.

The problem is to get this TFDPhysMSSQLDriverLink casting based on FDConnection.

Use the TFDConnection object's GetInfoReport() method, it takes a string list.  It shows everything you want to know about the connection and the driver it used/picked.  We have this on our login/splash screen hidden behind a TLabel double-click event because we were having the same types of issues.  Also look into the FDDrivers.ini file configuration.
