Presumably you have before insert triggers on the A tables to deal with this.

Still trying to work out why there is only 1 record involved. How can you
be sending data from 4 B tables to 4 corresponding A tables, and only have
1 record involved?

But this is not overkill?

I suppose you mean "..into the fields of the query on A..."?

That sounds like extra-ultra-super-duper-overkill, from the point of view
of clientside activity, compared to an IB_datapump.

If you must avoid using a datapump, at least do this the way the datapump
does it. Read a TIB_Cursor on the B table and plug the values directly
into an IB_SQL.

SQL on the B table (in an ib_cursor):

select field2, field3, field4, ....
from TableInB
where <whatever>

SQL for A table (in an ib_dsql):

insert into TableInA(field2, field3, field4, ....)
values(
:field2,
:field3,
:field4,
.....
)

Then, opening the ib_cursor using First(), just step through it until
EOF. Just before you call next, call a proc that does this:
var
jj: integer;
...
with CursorOnB do
...the other stuff;
if not ib_DSQLforA.Prepared then
ib_DSQLforA.Prepare;
for jj := 1 to FieldCount - 1 do // ignore 0 as it is the primary key
ib_DSQLforA.params[jj-1].Value := Fields[jj].Value;
ib_DSQLforA.Execute;
Next;
...

Well, this isn't one of 'em.
