Subreports with only one data record

rbuser

I am using D7 and RB 7.02 with MS SQL and ADO linked queries. I have a
report based on employees where the detail section prints one line per
month. In the group footer, I have a subreport which is suppose to print
another 12 lines for the same employee. The main report prints fine, but the
subreport is only printing the first record (out of 12). I have seperate
query objects (linked on EmployeeId) and db piplelines for the main report
and the subreport.

What am I missing?

Make sure the subreport is connected to the detail datapipeline. A
report/subreport that is not conncted to a datapipeline will by default
print a single detail record. The data-aware controls such as DBText will
print from the current record. Thus the effect of printing the only the
first record.

I cannot determine from you description whether you are linking the queries
using RB's Data workspace or using external datasets. If you are using
external datasets, you can check the linking relationship by placing two
DBGrids on a form and connect to the queries. Below is an article on linking
datasets:

Tech Tip: Linking SQL Queries for Master/Detail Data
------------------------------------------------------

The following example shows two options for linking SQL queries to create a
master/detail relationship.

In this example, we are using Delphi's DBDemos data to create a
Customer/Order relationship. Thus we wish to link the Orders detail to the
Customer master.

I. Delphi Query Linking
------------------------

a. Set the detail TQuery.DataSource property to point to the master
query's TDataSource component.

b. In the SQL "Where" clause for the detail query use a ':' followed by
the linking field name from the master:

example
select *
from orders
where orders.CustNo = :CustNo

Now each time the master record position changes, the detail query will
automatically be refreshed with the correct result set.


II. RB DataPipeline Linking
-----------------------------

a. Set the detail DataPipeline.MasterDataPipeline to point to the master
DataPipeline.

b. Use the detail DataPipeline.MasterFieldLinks property to define the
linking relationship

c. In the SQL for the detail, retrieve all records and sort them by the
linking master field:

select *
from Orders
order by CustNo


Notes:

1. Using RB DataPipeline, each query is executed only a single time - thus
performance is much faster.

2. RB Professional and Enterprise Editions include a visual Data environment
for creating SQL queries, defining linking relationships, and creating
Ask-At-Runtime parameters. Using the RB tools you could create the above
linked queries in about 10 seconds.
