In the FD form, the Default Column Name property is the SQL column name that will be assigned by the Designer when the data item is used as a column in a table. When the Default Column Name property is first generated, it is derived from the COBOL data-name according to a set of rules for defining default column names.
The column name may be changed after a column is created by using the Column Name property in the Table form.
Column names may not be SQL reserved words.
