when I used -READ to get the all field.

below is my code:
 

TABLE FILE SQLOUT
PRINT *
END

the result is 

ID       Name   address
1111      a       aaa
2222      b       bbb
3333      c       ccc
4444      d       ddd

TABLE FILE SQLOUT
PRINT
COMPUTE Cntr/I9 = LAST Cntr + 1;NOPRINT
COMPUTE TEST1/A15 = FTOA(ID, '(D10)', TEST1);NOPRINT
COMPUTE AllID/A1000V = IF Cntr EQ 1 THEN TEST1 ELSE AllID|| ',' || TEST1;
ON TABLE HOLD AS TMP1 FORMAT ALPHA
END
-RUN

WHEN I CODE :

TABLE FILE TMP1 
SUM LST.AllID AS 'AllID'
ON TABLE SAVE AS TMP2
END
TABLE FILE TMP2
PRINT AllID
END
-RUN


I can get the result :
1111,2222,3333,4444

but, when I use -READ to get this value
-READ TMP2 &AllID.A100V. 
-TYPE &AllID;


the type is : 0003201111,2222,3333,4444

why not is 1111,2222,3333,4444 ??what's this "000320" ?

Is the code wrong?


Thanks,
James

quote:
A100V

leading 6 characters of AnnnV columns is always the length because V means variable and so
WebFocus needs something to tell it how long the field is.

If you do not reformat it as fixed length then you need to code

-READ TMP2 &X.A6. &AllID.A100.

Do not use V on the -READ format it is not valid and even if it works today it might not tomorrow

James, you're going against an SQL source. It's not the -READ that generates the column length it's
the extract request.

If the source column is varchar, varchar2 etc. then WebFOCUS will automatically generate then hold file created
with the leading character count.

If it's char or a numeric format then it will not. Because they are by definition fixed length.
