Dear masters,
I would like to return ROW-Type as result of FUNCTION oder PROCEDURE in ESQL.
In editor it is all OK. But if I deploy my code, I get:
BIP2402E: (de.deutscherring.wbimb.lv.db_mappings.LV_StagingArea_beschreiben_ExtractTarife.getTarif, 1.60): Syntaxfehler: 'keyword Row'.
My function was inside and outsind module and is VERY simple:
CREATE FUNCTION getTarif( vp_nummer INT ) RETURNS ROW
BEGIN
DECLARE result ROW;
SET result = ROW( Environment.Variables.SCHL_BEGR AS SCHL_BEGR,
...
RETURN result;
END;
What did I making wrong?
Thank you very much!!

You can't do this, I think.
I think you can return a reference, though.

Jeff is correct. Functions and Procedures in ESQL cannot return ROWs or LISTs.

Dear Masters,
my toolkit-hint was, that it is possible, so I tried the ROW.
But if I now try to use REFERENCE it doesn't work.
CREATE LASTCHILD OF OutputRoot.MRM NAME 'GRTK2Y4';
MOVE tarifZeiger LASTCHILD;
getTarif(2, tarifZeiger);
Toolkit shows "Syntax Error".
Procedure is:
CREATE PROCEDURE getTarif( IN vp_nummer INT, INOUT zeiger REFERENCE )
BEGIN
DECLARE result ROW;
SET result = ROW(
Environment.Variables.SCHL_BEGR AS SCHL_BEGR,
...
);
SET zeiger = result;
END;
What is wrong here?
Thank you very much!!!

You can't assign a ROW to a reference.
I don't know for sure that you can do this, but you can try:
| Code: |
Declare myRef REFERENCE to result;
set zeiger = myRef; |
You might be better off just doing
| Code: |
set zeiger=ROW(
Environment.Variables.SCHL_BEGR AS SCHL_BEGR,
...
); |

Hi jefflowrey,
could it be, that Environment get LOST in this case?! I use my new Procedure in the SAME module as the MAIN-Procedure calling this getTarif() but the debugger shows no values for Environment... 
Thank you very much!

The Environment tree should never get lost.
It may be that you didn't update it correctly, if you updated it inside a user defined procedure.
