Question Past Temp-table between files

[Vincent Bourbeau]

Hi
Here my need, I want to create a file (eg proc.p) with in input parameter a temporary table. So I can call this file in another program. The table that is passed as a parameter can be different depending of the program that call it.
The only thing I got is to pass table in parameter but it must be previously declared in the second file. But as I said I don't know what table will be passed.
What I want to do is a procedure which copies a table into SQL a temporary table passed in parameter. If you know bether solution ...

Do I need to use handle or something like that?

 

[Stefan]

Look up TABLE-HANDLE - this passes the table and its definition dynamically.

 

[Vincent Bourbeau]

The TABLE-HANDLE passes the HANDLE of the Temp-table but how can I use it... This Handle only alow me to add fields not to query the temp table?

You can create a dynamic query on the handle.

CREATE BUFFER lv-Buffer FOR TABLE ip-TableHandle:DEFAULT-BUFFER-HANDLE.

CREATE QUERY lv-Query.
lv-Query:SET-BUFFERS(lv-Buffer).

lv-QueryString = "FOR EACH " + ip-TableHandle:NAME.

lv-Query:QUERY-PREPARE(lv-QueryString).

lv-Query:QUERY-OPEN.

lv-Query:GET-FIRST.

DO WHILE NOT lv-Query:QUERY-OFF-END:
  **something**
  lv-query:GET-NEXT. 
END.

lv-Query:QUERY-CLOSE. 
DELETE OBJECT lv-Query.

Yuck (I nearly reported your post for this... ;-)):

lv-Query:QUERY-OPEN.
lv-Query:GET-FIRST.
DO WHILE NOT lv-Query:QUERY-OFF-END:
   **something**
    lv-query:GET-NEXT.
END.
lv-Query:QUERY-CLOSE.

Yum:

hq:QUERY-OPEN().
DO WHILE hq:GET-NEXT():
   ** something **
END.
hq:QUERY-CLOSE().

lol Stefan I had no idea you could do that. You learn something new every day. Thanks.

Everything seems to work but how do I get the values?

I try DISPLAY lv-Buffer:BUFFER-FIELD(1):BUFFER-VALUE.

But it's empty?

 

[Vincent Bourbeau]

The do-while only loop 1 time but in the call procedure I add 2 entry on the temp table. As if the table are empty.

 

[jdpjamesp]

Can you post the definitions at the top of the procedure, as well as the call to it?

 

[Vincent Bourbeau]

Ok it's work... I use MESSAGE instead Display.

 

[Vincent Bourbeau]

Why only "MESSAGE" work. I try to stock value on variable and Display it and that don't work. here the code...

test.p
 
 
DEFINE VAR h-table AS HANDLE.
 
DEF NEW GLOBAL  SHARED TEMP-TABLE  t-test
FIELD c-test AS CHAR.
 
CREATE  t-test .
ASSIGN t-test.c-test ="eee".
 
CREATE  t-test .
ASSIGN t-test.c-test ="fff".
 
h-table = TEMP-TABLE t-test:HANDLE.
 
RUN mods/custom/test2.p(INPUT TABLE-HANDLE h-table).

test2.p
 
DEFINE INPUT PARAMETER TABLE-HANDLE t-handle.
DEFINE VAR c-display AS CHAR.
DEFINE VAR b-handle AS HANDLE.
DEFINE VAR q-handle AS HANDLE.
 
CREATE BUFFER b-handle FOR TABLE t-handle:DEFAULT-BUFFER-HANDLE.
b-handle:BUFFER-CREATE.
 
 
CREATE QUERY q-handle.
q-handle:SET-BUFFERS(b-handle).
q-handle:QUERY-PREPARE("FOR EACH t-test").
q-handle:QUERY-OPEN.
 
DO WHILE q-handle:Get-next():
 
    DISPLAY b-handle:BUFFER-FIELD(1):BUFFER-VALUE.
    MESSAGE b-handle:BUFFER-FIELD(1):BUFFER-VALUE.
    ASSIGN  c-display = b-handle:BUFFER-FIELD(1):BUFFER-VALUE.
    DISPLAY c-display.
 
 
END.

Your problem most likely is flushing - which reminds me of the good ole V6 days ...

Seriously: Progress automatically always creates a frame to display. The default is a single frame unless you specify otherwise. In order to get a down frame you must use a "real" loop like REPEAT instead of DO. A single frame only displays one lineand overwrites it on each iteration of your "pseudo" loop.

To illustrate that try the following

DEFINE VARIABLE counter AS INTEGER    NO-UNDO INITIAL 10.
DO WHILE counter > 0:
    ASSIGN counter = counter - 1.
    DISPLAY counter.
END.

vs

DEFINE VARIABLE counter AS INTEGER    NO-UNDO INITIAL 10.
REPEAT WHILE counter > 0:
    ASSIGN counter = counter - 1.
    DISPLAY counter.
END.

Isn't default behavior funny?

Heavy Regards, RealHeavyDude.

 

[Vincent Bourbeau]

Yes that is... Thank you guys. It's the first time I have to play with handle, I learn a lot with this case. I hope all will work find for the rest of my procedure.

Thanks

Just as a note, you can also get the BUFFER-FIELD by name, so if your table has a field on it called CustomerNumber on it, then you can get it by b-handle:BUFFER-FIELD("CustomerNumber"):BUFFER-VALUE. The advantage of this is that you can shorten it to b-handle::CustomerNumber. This came in in v10 IIRC.
