IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Assign a timestamp to a date/time field without %date() / %time()

When assigning a timestamp to a date field or a time field it shouldn't be necessary to use %DATE() or %TIME() to do this.


Use Case:

D dateIso1 s D
D dateIso2 s D
D timeStamp s Z inz(*SYS)
C eval dateIso1 = %date( timeStamp )
C eval dateIso2 = timeStamp

The first statement with dateIso1 compiles OK.
The second statement with dateIso2 causes a compile error.
The second should be allowed because it is obvious what is to be done. It is the equivalent to moving numeric fields in different formats ( zoned, packed or integer) into another numeric field.

    IBM does not intend to provide a solution to this request at this time, so it is being closed.

    IBM's position is that allowing implicit conversion between Timestamp values and Date or Time values would not improve the clarity or maintainability of the RPG code.

    If the table is defined using DDL, wouldn't you be able to set the relevant columns to default to CURRENT DATE/TIME/TIMESTAMP and not include them in the RPG at all? The column would be updated correctly at write time and fully accessible for read/update. The reason I suggest this is because I thought IBM was recommending against DDS over DDL for physicals & logicals, which is what we've been trying to do.

    There are pro's and cons on automatic type casting... it saves you the %Date function (but is this such a major issue ?), but on the other hand you're not warned if you loose the time information (maybe it wasn't intended).
