Re: Long names and Data structures based on SQL Table problem

Questions for you.

1) What release are you on? And are you up-to-date on database PTFs. Many restrictions on usage of a DS in this manner have been released over the years.

2) Does it work if you use the original myTable DS as the target?


P.S. There is nothing "special" about a service program - that will not be the cause. You say "during srvpgm compilation" but that is not possible - there is no such ability built-in to the system. You are compiling a module - the system has no idea that you will eventually put it in a service program.

Hello,

I have an SQL table with long names. Based on below article I've tried
to declare Data Structure based on this table so I can select all
columns to my Data stucture in service program. Problem is that
I always get Error "XXX is not defined or no usable" during srvpgm
compilation where XXX is the name of DS which is based on another DS
with extname and alias. Even if I use main DS(the one with extname)
error is the same. I thought that adding alias will fix problem with
long names. When I declared the same DS but I've specified all fields
explicitly, compilation was successful.

http://www.rpgpgm.com/2018/05/how-to-sql-tables-long-names-in-rpg.html

Dcl-Ds myTable extname('tableName':*ALL) qualified alias;
End-Ds;

Dcl-ds myTable_X likeds myTable);

Exec SQL
select * into : myTable_X from tableName where ID= :UserId;

This on is failing. SQL always return one row of data. After I change
DS and declare all fields (70...) myself, it starts to compile. I
really don't know why. Any idea? Maybe this can't be done with srvpgm?
I handle nulls in table by using ALWNULL(*INPUTONLY).

Best Regards
Filip
