OCCURs are handled automatically by c-treeRTG when converting this table into SQL. c-treeRTG automatically expands every OCCURS into multiple fields, using numbered extensions such as "_1", "_2" and so on. Because we are not explicitly using the groups for field naming in this example, the final fields to be displayed in SQL will be the most internal ones. After sqlizing this table, you can view it in SQL Explorer to see the following fields:
CARD_LABEL_NUMBER_1
CARD_MAIN_NUMBER_1
CARD_NUMBER_CRC_1
CARD_LABEL_NUMBER_2...
This might cause some field name conflicts, depending on how your fields are named in COBOL. In this example, if we had named VALID-UNTIL-DATE-1X without the final X, a conflict would happen and you would not be able to sqlize.
