RE: SQL pre-compiler & the new Template keyword

Hi Alan,

Issue resolved by Gina's email, but to cover your questions of my code

ExtName does not qualify a DS, which is why I had to explicitly state Qualified.
SQL can load a host data structure array. I'm not sure when that was introduced.

I appreciate you taking the time to help me out.

Thanks,
Kurt

Ok, template looks ok.

d TD_CalTypeId...
d e ds ExtName(CALTYPIDP)
d Qualified
d Template

Not sure why the first definition is compiling. It shouldn't because you are specifying Qualified again. It should be.

d dsCaltypId...
d ds LikeDs(TD_CalTypeId)
d Dim(MAX_READ)

The third one is defined correctly but I don't think SQL supports Array of records yet. Try making it a multiple occurance data structure.

d dsCalTypId...
d ds LikeDs(TD_CalTypeId)
d Occurs(MAX_READ)

Alan, that's good to hear.
I guess my next step is to see if we can get the latest PTF cume (we
are never up to date on them). But even so, I found a handout by
Barbara Morris stating that the SQL Precompiler, " Supports all the
new features in ILE RPG V6R1." Which means I either have a code issue, or I need to open a PMR.

I'll give some more detail (as it turns out the caveat I previously
mentioned wasn't exactly what's happening in my situation).

I have a copybook with the following D-spec.
// Shared Templates
D dsTmpl_CalTypTID...
D E DS Qualified Template
D ExtName( 'CALTYPTIDP' )

In the service program module, I have the following code, which does
compile:
D ds_CalTypTID E DS ExtName( CalTypTIDP ) Qualified
D Dim( MAX_BLOCK_READ )

However what I want is this, which does not compile (due to SQL below).
The Verifier says this is ok for the rest of the RPG code.
D ds_CalTypTID DS LikeDS( dsTmpl_CalTypTID )
D Dim( MAX_BLOCK_READ )

The SQL that uses this DS based on a Template that is failing in the
pre-compile is this:
Exec SQL
Fetch CalTypTIDPCursor FOR :epMaxRead ROWS into :ds_CalTypTID;

Precompiler listing:
DS_CALTYPTID 53
DS_CALTYPTID **** 1098

SQL5011 30 1098 Position 59 Host structure array DS_CALTYPTID not
defined or not usable.

Interesting. I suppose one caveat is that these are procedure
parameters defined like template data structure subfields. Are you
doing
that as well?

Thanks,

It was at V6R1. I do it all the time

Does anyone know if we can expect the SQL pre-compiler to be
updated any time soon to allow for the use of variables that have
been defined like a variable/DS that has the Template keyword specified?
We use the Template keyword a lot. Most of our file encapsulated
service programs include a template of the file in the copybook
that the service program uses for defining pretty much all
variables related to the file (and for prototypes, which is why
it's in the
copybook).

I'm taking a stab at creating a file encapsulated service program
using SQL instead of native I/O and quickly discovered that the
SQL pre-compiler is not a fan of templates.

I'm at IBM i 6.1.
