Applications do not have to add braces around the attribute value after 
the Driver keyword unless the attribute contains a semicolon (;), in 
which case the braces are required. If the attribute value that the 
driver receives includes braces, the driver should not remove them but 
they should be part of the returned connection string.

See if something like below works:

{db; name}

Hi,

Thanks for the responses.

I tried putting curly brackets around the value of database like you
mentioned.
{db; name}
But the server was treating the brackets as part of the database name and so
did not work.
I tried double quotes like 
"db; name" which also didn't work.

Not sure what else I can try or whether the ODBC driver supports database
name with a semicolon at all.
I know that in the case of password we can put the string enclosed within
curly brackets to escape special characters but not appears to be working
for the database.

Regards,
Joby

Not knowing much about ODBC, how about single quotes?

And if you pass the entire URL, would it be possible to pass instead  
values to Kind of function?

Kind regards Thiemo
