Numeric conversion overflows on retrieval assignments may be handled differently by different IBM relational database products. For example, consider fetching a float column into an integer host variable from DB2 Universal Database for OS/390 and from DB2 Universal Database. When converting the float value to an integer value, a conversion overflow may occur. By default, DB2 Universal Database for OS/390 will return a warning SQLCODE and a null value to the application. In contrast, DB2 Universal Database will return a conversion overflow error. It is recommended that applications avoid numeric conversion overflows on retrieval assignments by fetching into appropriately sized host variables.
