Question

Does CPYTOIMPF really unpack data with STMFCODPAG(*PCASCII)?

Asked by: MsDeveloper

I am using SQLRPGLE to run an sql statement, creating a new db file.  I am using cpytoimpf to create a .csv of the sql output and it's going to the IFS.  I am then running secure FTP using a qshell program to move the .csv file over to a sql server.  I need the packed data to not show as packed once it gets to the sql server.

Here's my code:
CPYTOIMPF  FROMFILE(&XTCTLIBL/&FILE1) TOSTMF(&TOFILE)
            MBROPT(*REPLACE) STMFCODPAG(*PCASCII) +  
            RCDDLM(*CRLF) STRDLM(*NONE) +            
            DATFMT(*USA)                            
            RMVBLANK(*TRAILING) DATFMT(*USA)        *

Here's my data:
Source Data:  
packed6     P       6    0   218  <== showing up as junk after cpytoimpf to ifs
Field2         S       3    0     1
Field3        S      12    0     4
Field4        A       1         16

Doing above copy to impf, results as this:
Field2, Field3,Field4,   Packed6 field
xxxxxxx1  ,0,101907  ,ñðñùð÷
xxxxxxx2  ,0,62508   ,ðöòõðø  
xxxxxxx3  ,0,121208  ,ñòñòðø  

From what I've researched, CPYTOIMPF with STMFCODPAG(*PCASCII) should unpack the packed6 field to numeric.  Is my understand correct?  Does OS matter - we are V5R4.

Do you know how else I can do sqlrpgle (using straight sql, no real rpg in this) and get the packed to go to IFS as numeric?

MsDeveloper:

It always unpacks for me regardless of OS version/release. (There are always possible PTFs that might be involved.) Multiple possibilities might influence the result --

Does &TOFILE exist before CPYTOIMPF is executed? If so, what attributes are assigned to the file?

What is the system QCCSID value? What is the definition of the column in the SQL table? Can you show a simple green-screen query of a few rows of the SQL table? If the table is created by the RPG program, how is data inserted into the rows?

Nothing jumps out to me as the most likely cause. A few questions/answers should narrow things down.

Hi, Thanks for the quick response.  The &TOFILE did exist, so I deleted it and executed the create and cpytoimpf again.  Can you tell me how to get the system QCCSID please?  

The table is created by the rpg pgm.  I am doing a create statement via sql:
C/EXEC SQL                                              
C+  CREATE TABLE MYTABLE AS                    
C+    (SELECT                                          
C+      KEY_NUMBER,                            
C+      STATUS,                                
C+      PACKED_6,                                        
C+     CASE WHEN LENGTH(TRIM(CHAR(PACKED_6))) = 5 THEN    
C+             '0' CONCAT LEFT(TRIM(CHAR(PACKED_6)),5)    
C+           WHEN LENGTH(TRIM(CHAR(PACKED_6))) = 6 THEN  
C+             LEFT(TRIM(CHAR(PACKED_6)),6)              
C+           ELSE NULL                                  
C+     END AS COLUMN0000                                
C+     FROM                                            
C+      FILEA,                    
C+      FILEB


File Definition from the create statement above:
Field                        
Name                  Type  Length Dec  
KEY_NUMBER        S      10    0  
STATUS                   A       1        
PACKED_6                 P       6    0  
COLUMN0000            A       9        

The PACKED_6 is really a date shown like this:  112108.  They want it formatted as this: 11/21/2008, but they want both columns downloaded.  Now that I take a closer look, I am getting the 112108 (which is the packed field) and it is unpacking it nicely... I am not getting the 11/21/2008 date.  It is showing like this:  ñðñùð÷

Here's my output from greenscreen (the downloaded .csv is the same too)
1111111111      0      101907      ñðñùð÷
2222222222      0      62508      ðöòõðø
3333333333      0      121208      ñòñòðø
4444444444      0      71608      ð÷ñöðø
5555555555      1      52609      ðõòöðù
6666666666      0      102907      ñðòùð÷
7777777777      0      52008      ðõòððø
8888888888      1      21909      ðòñùðù
9999999999      0      70609      ð÷ðöðù
1111111112      0      110807      ññðøð÷
1111111113      0      92507      ðùòõð÷
1111111114      0      62909      ðöòùðù
1111111115      1      42607      ðôòöð÷

What s the CCSID of the COLUMN0000?  Compare it to the Status column.  Use the CCSID keyword on your create table to force the CCSID to match the CCSID of the STATUS column, and life should be good, since STATUS is also a character column and converts properly.

You can use the green-screen command DSPFFD to get the CCSID of each column, or use IBM iSeries Navigator in Windows to browse to the table (under Database) and pull up the column properties.

The CCSID of COLUMN0000 is this:
FIXEDDATE  CHAR            9      11        16        Both     FIXEDDATE    
  Variable length field -- Allocated length :  None                          
  Allows the null value                                                      
  Coded Character Set Identifier  . . . . . :  65535                      <===

Do you have syntax for using the ccsid of STATUS on COLUMN0000?  My statement is above and I don't know where to stick in the forced ccsid of 37.  The STATUS column is CCSID 37, which is char i'm assuming.

 

by: MsDeveloperPosted on 2009-10-27 at 11:47:50ID: 25675966

I found an example of casting to change the ccsid:
SELECT emidnm, emfnam, CAST(emlnam AS CHAR(20) CCSID 37)
I'm going to give it a try.

 

by: MsDeveloperPosted on 2009-10-27 at 12:51:02ID: 31646169

Thanks - This helped a ton! I was able to do the cast, then add the '/' using substring and concat.  Not sure if the substring and concat was the cleanest solution, it works however. Thanks again!!!
