I am implementing a Firebird 3 connection component for MSEide+MSEgui (a Free Pascal toolkit) so I don't know the returned data of the statements in the first place. In case of input params I implemented an own IMessageMetadata derivate which uses the type information of TParam in order to setup the metadata. In case of "returning" the data type is unknown without parsing the SQL statement. It seems I always need to prepare the statement first?

Signature of execute in firebird.pas is: " function execute(status: IStatus; transaction: ITransaction; inMetadata: IMessageMetadata; inBuffer: Pointer; outMetadata: IMessageMetadata; outBuffer: Pointer): ITransaction; " A value for outMetadata probably is available by IStatement.getOutputMetadata(). What if one wants to use IAttachment.execute() where no IStatement is available? How can one know if IAttachment.execute() or IAttachment.openCursor() must be called without having IStatement.getFlags() from a prepared statement other than parsing the SQL statement in user code? Does IAttachment.prepare() involve a server roundtrip? Thanks for your patience. Martin ++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.

And then how to get the data? Is using openCursor() not possible so one does not need to know if it is a SELECT or another statement?
