> Do you mean something like EXECUTE BLOCK in V2?

I suspect Rick is talking primarily about prepared statements.
Something like isc_dsql_exec2 that would take multiple XSQLDA as input
(isc_dsql_exec3? :-) .

For non-prepared statements EXECUTE BLOCK might do the trick, however
it has 64k limit and requires additional support from connectivity
components.

Is there any architectural issue that prevents passing multiple DML
statements to Firebird?
