How do you make child sub-commands visible in DataReport controls?

Hi all,

I created a DataEnvironment and a corresponding DataReport. The
DataEnvironment has a commaind (main table) and two other child-commands
that exposes related data other tables. The concept is identical to what the
NorthWind database uses with its "Orders" and "Order Details". I set the
report to point to the parent command ("Orders" in the case of the NorthWind
database) and then tried to drag and drop a child field from one of the
sub-commands to the Details section (or any other section for that matter)
and all I get is a circle with a line through it. If I add a text box and
then use the dropdown on the Data Member all I see is the parent command,
not the two child commands. I might point out that the report Data Member
objects sees all commands nicely. How do I get the report to accept data
fields from the various sub-commands, like in the NorthWind sample?

Thanks in advance,

Hi Veign,

I took a look at the sample. At least at first look, it wasn't very helpful.
DataReport1 uses DataEnvironment1 as its Data Source. I explained on my
other thread on how I set things up. If I run the report, I see everything
fine, okay sans the other two sub-tables. The problem is that unloding the
Data Report doesn't release the lock. When I go to print again and want to
manually delete the file, I get a permission denied. I visually see that
there is a ldb file indicating the lock, so hence the permission denied. To
my knowledge I'm not doing anything special.

Thanks in advance for any thoughts.

You asked about viewing child records in a DataReport. The sample shows the
use of a Shaped recordset to display a Parent / Child report in the
DataReport. You mentioned nothing about file locks in this thread.

Sorry, I guess that I'm just tired. I posted to the wrong thread. Although I
still have a lot to learn about the Data Reporter and SQL in general, I
think that there is a miscommunication. I'll look at your sample again, but
what I did is create a parent command using a custom SQL Statement. In its
simple for say:

Parent Command (DataEnvironment):
SELECT Table1.*, Table2.* FROM Table1 LEFT JOIN Table12 ON Table1.Key =
Table2.Key;

Sub Command (DataEnvironment)
SELECT Table3.* FROM Table1 INNER JOIN Table1 ON Table1.Key=Table3.Key;

When I attach the Data Environment to the DataReport, the DataReport
designer only allows me to access data from the parent, not the child
domains.

I created the SQL statements using Access, so I know they work, at least as
far as Access is concerned. Thanks a lot for your help Veign,
