Re: Reading using SQL and dealing with nulls

Hi Daniel,

That's true.  I was responding based on Darryl's "I am reading a system view in RPG."

Hi Peter,

I do believe - about 99% - that this H-spec keyword is only in respect of native I/O (using dcl-f files and read/chain/etc).

AFAIK it has absolutely no effect for embedded SQL.

Hi Darryl,

There's a H-spec keyword you can use:

If ALWNULL(*INPUTONLY) is specified, then you can successfully read records with null-capable fields
containing null values from externally described input-only database files. When a record containing null
values is retrieved, no data-mapping errors will occur and the database default values are placed into any
fields that contain null values. However, you cannot do any of the following:
• Use null-capable key fields
• Create or update records containing null-capable fields
• Determine whether a null-capable field is actually null while the program is running
• Set a null-capable field to be null.

Some of the fields have nulls.

I do not want to recode the data structure to ignore these fields as I may
need them.

  Is there a way to tell the compiler to initialize these fields?

  TIA
