Null column indicator character
ZDT/Db2 provides options that you can use to specify two null column
characters:
- Null column indicators: Input
- For use when editing a null column
- Null column indicators: Display
- Indicates a null column when it is displayed
In a Z Data Tools/Db2 editor session, entering the null column input indicator character in the first (leftmost) column of a column that permits null values indicates that the column is to have a null value. For ZDT/Db2 to recognize the null column input indicator character, you must type the selected character in the first position of the input field, and remove all the remaining characters.
ZDT/Db2 also provides an option whereby it interprets a column containing spaces as containing a null value.
