[RBASE-L] - Re: Limit to Long Varchar or Var for Varchar

Thu, 25 Jun 2009 16:02:23 -0700

According to the results I am getting at this moment, that seems to be legal. I cannot explain the anomoly that occured before, but I will chalk it up to operator error as I didn't do it in a file as I should have, but from the R>, so I lose the auditing of my own actions (which these days, I usually do audit them)...

Mike

This makes me nervous.

I changed my EEP code to the below and it seems to work
I started with 4194 in the Varchar field by doing
Edit all and putting the cursor on the field

Then Edit Using myForm, clicking the Button to add text and now
I have 6748 in the column

Set var vxSubj varchar = null
Select subj into vxSubj from ptsoap WHERE ptspid = .vptspid

SET VAR vadjdesc varchar = NULL
SELECT spdesc INTO vadjdesc FROM soapcode +
WHERE spcode  = .vscode AND COUNT = .vsprad ORDER BY spver

SET VAR vadjdesc2 varchar = NULL
SET VAR vadjdesc2 =  (SRPL((SRPL((SRPL(.vadjdesc, +
'[fname]',.vfname,0)), '[heshe]',.heshe,0)),'[himher]', .himher,0))

set var vsubjAll varchar = (.vxsubj + Vadjdesc2 + ' ')
UPDATE ptsoap SET subj = .vsubjALL  WHERE ptspid = .vptspid

So should I trust this or not?
Thanks everyone for helping
Marc

I get the same result now..   When I tested this before my last post, I 
did all the requisite checks like:


set var vc1 varchar = 'Mike'
set var vc2 varchar = 'Byerley'

set var vc3 varchar = ('Mike' + .vc2)  -- this resulted in the expected 
"Cannot add Text to Varchar"
set var vc3 varchar = (.vc1 + .vc2) -- this resulted in the expected 
"Cannot add VarChar to Varchar"



This does appear to be legal, but on the issue of concantenation in the 
UPDATE expression, I am sure you are hosed.

Now this seems to work.... maybe I am afraid to say but I see light at 
the end

of the tunnel

Set var vSubj varchar
Select subj into vSubj from ptsoap WHERE custnum = 4545

Set var vSubj = (.vSubj + 'iiiiiiiiiiiiiiiiiiiid 
xxxxxxxxxxxxxxxxxxxxxxxxxx ' +.vsubj)

UPDATE ptsoap SET subj = .vSubj  WHERE custnum = 4545
edit all from ptsoap WHERE custnum = 4545


Putting the cursor on the Varchar field seems to show it growing to 
30000


Now will using this in a form mess something up??

Hi Mike


This is the main selling point in my app and why I needed to update to 
7.6
I have been bragging on my new note features, huge notes, no more 4k 
limit .... on and on.



I thought 7.6 allowed full string manipulation on Varchar fields?  Man 
am I having a hard time

grasping this and looks like I am in over my head big time.


If I save to a file would I loose all the formatting stuff like Bold? 
Seems like this may be slow

on workstations too?

If I can not find a good way around this my app is dead and the guy
with the MS SQL Exp and .Net will win this little battle we have.


Using the Editor is not an option,  I need a DB Memo or Rich Edit on 
the form
the user presses a button and a paragraph of text is added to the 
bottom of the
"notes"  anything less will not keep up with the Jones so to speak. 
Also, the lookup
text is only 4k currently and in a note field, some users want that to 
be bigger where

we look up 12k from a table then drop it into this form.


This is something I am suppose to have done in July and of course I was 
counting my

chickens too soon.

Some days I regret I do not drink
Marc

You can't add text, note, OR Varchar data to another Varchar, but 
since you include your manipulation in an expression "UPDATE ptsoap 
SET subj = (subj + 'iiiiiiiiiiiiiiiiiiiid ')  WHERE custnum = 
4545...", The engine has placeholders for upto Note datatype.  So even 
though your column is type VarChar, in the Expression it is converted 
to Note, making it a Note concantenation, which is legal, but the 
placeholder is also of Note length, truncating the returned data.  You 
are going to have to jump through some hoops to concantenate your 
VarChar data. The "Continue" parameter of the WRITE command doesn't 
work with VarChar data, so you can't


Output SomeFileName.txt
Write .vVC1 CONTINUE
Write .vVC2
out scr
set var vSUBJ = ['SomeFileName.txt']
UPDATE ptsoap SET subj = .vsubj  WHERE custnum = 4545


The only other way I can think of is to use a hidden variable listbox 
and first write your VarChar data to a file, then using the 
Load_From_Filename property of the listbox, load the varchar data. 
Then you can take the first line or last line as it pleases you, 
concantenate the data, then Save_To_Filename from the ListBox, then 
set your VarChar data to the diskFile, then perform your update.

Man this is nuts

I did
Edit all from table where custnum = 4545...
Double click the Varchar field
I pasted several paragraphs until I had 200 lines and 18326 bytes

I put 11111111111  222222222222222   3333333333 between the paragraphs 
I cut and pasted

to make it easy to see what I was doing
Exit Save ...

Edit using Form, looked in form and all the data was there


UPDATE ptsoap SET subj = (subj +  'iiiiiiiiiiiiiiiiiiiid ')  WHERE 
custnum = 4545...


edit all from ptsoap WHERE custnum = 4545
ALL data past 4k is now Lost and deleted


Then I went to RRBYW14
Contacts

added VC column Varchar repeated the same process cutting and pasting 
a bunch of text to get 18 k

Update ...........
got the same results
18k dropped to 4k after the Update command

So what is the secret to get a Varchar to hold more than 4k?

Marc,

This is starting to sound like a structure issue.
A while back I had a table that had 4 notes in it. I started having
trouble with it as people were getting verbose in their typing.
I had to split the table into 4 seperate tables with 1 note in each
table.

In 7.6 the row length is limited to 4096.

I don't know if that is what is going on for you or not.

Jan

 I started with a new DB,
  ALTER TABLE ptsoap ALTER subj TO subj VARCHAR (30000)


 UPDATE ptsoap SET subj = (subj +  'ddddddddddddd ')  WHERE custnum = 
4545 and ptspid = 4164

 Error value will be truncated

 I still only get about 4k in the Varchar field

 Something is Strange and the Varchar is acting like a note field even 
from the R>

 either use Long Varchar:

 LONG VARCHAR
 Same as VARCHAR, with a length of 256 MB

 or

 VARCHAR
       · Holds alphanumeric data; you must set the maximum length


       · If you set the maximum length to a value over 32,767 
characters, the limit is ignored and defaults to 256 MB





 Regards,
 Alastair.

   Hi


   I have a form with a Varchar field for notes.  I can only get about 
4k in the varchar field
   I use this code in a EEP that adds paragraphs to the end of the 
Varchar field. It works
   great up to a point then quits working as if I hit a limit like 4k 
for a note field.


   No errors on Trace.


   I knew at one time the Property command in 7.5 was limited to I 
think 1500 characters
   So I had to use this Update method but it looks like I hit another 
limit some where but I

   do not know what?

   This is the major request we have, larger notes

    SET VAR vadjdesc varchar = NULL
    SELECT spdesc INTO vadjdesc FROM soapcode +
    WHERE spcode  = .vscode AND COUNT = .vsprad ORDER BY spver

    SET VAR vadjdesc2 varchar = NULL
    SET VAR vadjdesc2 =  (SRPL((SRPL((SRPL(.vadjdesc, +

    '[fname]',.vfname,0)), '[heshe]',.heshe,0)),'[himher]', 
.himher,0))


    UPDATE ptsoap SET subj = (subj + .vadjdesc2 + ' ') +
    WHERE ptspid = .vptspid
    PROPERTY table ptsoap 'refresh'

   Thanks
   Marc
