The short answer is yes. :-)
In practice it probably depends on the SQL you will be using.
If you have Firebird 2.5 installed I can give you example code.
I tried this using ADO in dBASE 12.3.1 but there is a bug which causes
the report to only show 1 record. Accessing the Firebird table via the
BDE with a normal query works just fine.
It is quite possible that accessing a different SQL server using ADO
will work.
Two screenprints are attached. The first shows a section of the report
for all records. The second shows records for date between 1990-01-01
and 1990-12-31. I haven't ordered the records for the examples.
Mervyn.
