Reports are registered in two DB2 tables. The first table, named Q.REPORTS, stores information about the characteristics of a report, as described above. There is one row in Q.REPORTS for each registered report. The second table, named Q.REPORT_VARIABLES, stores information about the runtime variables used by each registered report. There is one row in Q.REPORT_VARIABLES for each host variable or variable used by each report in Q.REPORTS.
