Hi all,
I would like to know if there is a way to retrict the maximum number of records(BO's) the adapter retrieves from the database.
Say, for instance I have modelled business objects as given below.
OUTER_BO (WRAPPER=true)
--EMPID
--EMPNAME
--INNER_BO (TN=EMPLOYEE;SCN=) - CARDINALITY:'N'
----EMPID (CN=EMPID;FK=EMPID) - KEY:'Y'
----EMPNAME (CN=EMPNAME; FK=EMPNAME) - KEY:'Y'
Now, based on the values I set to the fields 'EMPID' or 'EMPNAME', records will be fetched from the database into the childBO. However, I would like to know if it is possible to restrict the number of child BO's to generate, to a finite integer.
I'm using WBIMB(5.0.5), JDBC Adapters(2.6) and Oracle (10G.R2).
I tried using the 'ResultSetEnabled' and 'ResultSetSize' properties of the connector to limit the records returned by the adapter. Nevertheless, that turned out to be of no use.

I am not sure how this can be done in MB
But while using ICS.. we can handle this in the mapping code where we can restrict the number of child objects which can be created. may be this can also be done in MB... just a guess..
