isCOBOL DatabaseBridge : Invalid Data
Invalid Data
Not all COBOL data is valid for the RDBMS.
DatabaseBridge transforms invalid data in the following way:
if NULL is read from the database, they're stored as spaces in alphanumeric COBOL items and zero in numeric COBOL items.
If numeric COBOL fields contain alphabetic digits, spaces, low-values or high-values, they're automatically converted according to the MOVE statement rules. Space is converted to zero, “A” to 1, and so on... If the -n option is used while parsing EFDs with edbiis, zero will be written when non-numeric data is encountered.
If a COBOL field for which the DATE Directive was specified contains zero, spaces or low-values, the date specified by the iscobol.easydb.min_date configuration property is used.
If a COBOL field for which the DATE Directive was specified contains high-values, the date specified by the iscobol.easydb.max_date configuation property is used.
If a COBOL field for which the DATE Directive was specified contains an illegal date (i.e. 31th February), the date specified by the iscobol.easydb.inv_date configuration property is used.
