In this sample database, I have tables for Issues, Defects_DCRs and RFCs. The Issue table holds the main issue and the Defects_DCRs and RFCs tables hold stages of the issue as it is being tracked in other databases in the department. From the Defects_DCRs table, I need to display the DCR_Descrption associated with the issue. From the RFCs table, I need to display the Summary associated with the issue. Some main issues have a DCR_Defect, some have an RFC, some have both.
