Hi,
I have a query text, where the parameters have already been replace with question marks:

select ?, ?, ?

and I have also orderer list of the corresponding values in array of variant.

How do i execute such query?
I tried TMSConnection.ExecSQL, but this method expects named parameters in the sql text (:param1, :param2 etc.)

Thanks, Ludek.

For successful execution of the specified query, you should modify it to the following: SDAC generates parameters automatically, using the SQL query text.

... and sdac again parses all the params and changes it internally again back to ?, ?, ?...
I hoped, i could save this superfluous parsing and replacing using some low-level access, especially when the query contains 2000 parameters...

When parsing a query, we replace not just all the :ParamName entries with ?, but also create an internal structure for using parameters. So you can't use a query, in which parameter names are replaced with ?.
