If the column is defined as null capable, then you must update the null indicator map accordingly.
如果列被定义为支持空值,那么您必须相应更新空指示符映射。
RPG uses a 1 character field (like an indicator) to determine if a column contains nulls.
RPG 使用一个 1 字符字段(比如一个指示符)来确定列是否包含空值。
If the latter is true, then the indicator variable for that column is set to -5 which will set the column to the default value for that column.
如果是后一种情况,那么该列的指示符变量被设置为- 5,这将把该列的值设置为默认值。
