[SOLVED] Amper Variable not Storing Entire Content
Hi,

I am using the below code to get a long string value (1000 characters) and store it in amper variable &FNOTE1. The problem is when I use the variable I only get part of the string, not the entire string. If I use variable &FN2, it shows entire string but when I run the report, it prompts for variable &FN2, which I do not want. Can you please suggest how to get the entire string in the variable &FNOTE1 without it prompting for the variable when run? Thanks in advance!

 SQL
SELECT LISTAGG(FOOTNOTE, ', ') WITHIN GROUP (ORDER BY FOOTNOTE) FN2
 FROM (SELECT DISTINCT FOOTNOTE FROM COMP_DATA
  WHERE COMPONENT_ID >= 111
AND COMPONENT_ID <= 228
AND INCLUDE_IN_REPORTS ='Y');
TABLE
ON TABLE HOLD AS TEMPHLD1
END
-RUN

TABLE FILE TEMPHLD1
SUM FN2
ON TABLE HOLD AS CIS
END
-RUN
-READFILE CIS

-DEFAULTH &FNOTE1=&FN2.EVAL;

first, try validating that your READFILE actually got you something, by following the READFILE command with a
-? &F
which would show you the &vars starting with the letter F that you have in your workspace.

The variable FN2 does get the entire string. That I believe means READFILE gave the value to FN2 variable. But if I use this variable in the FOOTER and run the report, it prompts for FN2.

Initialize the variables:
-SET &FN2 = ;
-SET &FNOTE1 = ;

SQL
SELECT LISTAGG(FOOTNOTE, ', ') WITHIN GROUP (ORDER BY FOOTNOTE) FN2
FROM (SELECT DISTINCT FOOTNOTE FROM COMP_DATA
WHERE COMPONENT_ID >= 111
AND COMPONENT_ID <= 228
AND INCLUDE_IN_REPORTS ='Y');
TABLE
ON TABLE HOLD AS TEMPHLD1
END
-RUN

TABLE FILE TEMPHLD1
SUM FN2
ON TABLE HOLD AS CIS
END
-RUN
-READFILE CIS

-SET &FNOTE1=&FN2.EVAL;

Tom,

It did not work. I still get prompted for the FN2 variable and also it does not get the value. Is this because now the value is being SET?

Does this work?

-SET &RETAIL_COST=;
-RUN
TABLE FILE CAR
SUM RETAIL_COST
ON TABLE HOLD AS CIS
END
-RUN

-READFILE CIS

-SET &FNOTE1=&RETAIL_COST.EVAL;
-TYPE VALUE OF RETAIL_COSTIS &RETAIL_COST
-TYPE VALUE OF FNOTE1 IS &FNOTE1

If you are going to use .EVAL, you will need to make sure the string is enclosed in quotes.

This is how:

TABLE FILE TEMPHLD1
SUM FN2
ON TABLE HOLD AS CIS
END
-RUN
-READFILE CIS

-DEFAULTH &FN2='';
-TYPE FN2 : &FN2


People are abusing EVAL far too often. If you don't need to have the contents of your (Dialog Manager) amper-variable re-parsed by Dialog Manager, you don't need EVAL.

What about using ASNAMES

SET ASNAMES=ON
 SQL
SELECT LISTAGG(FOOTNOTE, ', ') WITHIN GROUP (ORDER BY FOOTNOTE) FN2
 FROM (SELECT DISTINCT FOOTNOTE FROM COMP_DATA
  WHERE COMPONENT_ID >= 111
AND COMPONENT_ID <= 228
AND INCLUDE_IN_REPORTS ='Y');
TABLE
ON TABLE HOLD AS TEMPHLD1
END
-RUN

TABLE FILE TEMPHLD1
SUM FN2 AS 'FNOTE1'
ON TABLE HOLD AS CIS
END
-RUN
-READFILE CIS



This way you do not need FN2 as variable it reads it directly into FNOTE1

This is why you are getting prompted.

To my knowledge (wait for the flood of responses here) you are not able to supply a variable to a -DEFAULT or -DEFAULTH.

I'll not bother to go into the reasons why this might be illogical to do anyway!

This has been discussed a few times before.

Hi Tony,

With the .EVAL is does work.

But only with the .EVAL

Hi Waz,

When did that happen? I thought that this was one of those "if only we could" things that we dream of!

Well, you're never too old to learn something new Smiler

Well, knock me down with a feather!

using the following (i.e. -DEFAULTHing &FN2) works OK, but for me I'd rather use the suggestion by Fernando unless there's a really good reason that you need &FN2 elsewhere within your code

T

Edited to change DEFAULTH statement after being corrected by Danny Razzer

-DEFAULTH &FN2 = ''

TABLE FILE CAR
BY MODEL AS FN2
WHERE CAR EQ 'JAGUAR'
ON TABLE SET HOLDLIST PRINTONLY
ON TABLE SET ASNAMES ON
ON TABLE HOLD AS TEMPHLD1
END
-RUN

TABLE FILE TEMPHLD1
SUM FN2
ON TABLE HOLD AS CIS
END
-RUN
-READFILE CIS

-DEFAULTH &FNOTE1=&FN2.EVAL

-TYPE &FNOTE1
-TYPE &FN2

It stands to logic that you can assign a variable to another with -DEFAULT using .EVAL
&FN2.EVAL is replaced by its value before assignment, hence it behaves as a constant and not a variable.
What I am fearful about is the semi-colon. I know that many users put a semi-colon at the end of a -DEFAULT as some also put a semi-colon at the end of a -GOTO command.
It seems innocuous but then one day the code will be tightened and then...

And with .EVAL most dialog manager commands can be controlled.

I once set up a GOTO for -INCLUDES inside the calling fex.

Consider this simplified example.

Include:

-SET &RTN_CONTROL = IF &FOCERRNUM NE 0 THEN 'GOTO ERROR_CONTROL' ELSE '*' ;

Calling Fex:
.
.
-INCLUDE Fex

-&RTN_CONTROL.EVAL

-EXIT

-ERROR_CONTROL
.
.
.
