How do I accomplish “use null ‘no date’ ” ?

Assuming ILE RPG, try the ALWNULL() parameter when you compile the module.

Sorry to open this again but I didn’t understand DanTheDane’s response “If your datefield is defined as a ‘datefield’, I recommend to use null as ‘no date’” How do I accomplish “use null ‘no date’ ” ??

Date-type fields require a valid date, which may be the reason null values generate errors. The recommendation from Dan the Dane is popular.

Seems like you want to know upcoming demand for items by date.
You could set a default of the last date of the period in process.

The file is defined by DDS. I have tried adding ALWNULL but this has provided me with compile errors relating to providing a default value. I added a DFT(*NULL) but this apparently conflicts with the DATFMT(*DMY) keyword.

If your datefield is defined as a ‘datefield’, I recommend to use null as ‘no date’. You will understand this recommandation when you run query on the data column; – never more the ugly ’0001-01-01′ but a nice ‘-’ indicating that the datefield has no data in it.

How is the field actually defined now (what are its attributes)? Is this a DDS file or SQL table?
