Passing a value to a child data set

Migrateduser

<p>How do I pass a value from a main dataset to a child data set?  I'm using a JDBC connection.  My main data set is SELECT CLAIMID, PERSONID FROM CLAIM and my child data set is SELECT PERSONID, FIRSTNAM, LASTNAME FROM PERSON.  I want to show the child data set in a table under the main data set so it will show claim information then under it person information.  I need to pass the PERSONID from the main data set to the child.  Any ideas?</p>
