Marc,
There is one catch that you need to consider. If the table in question has
a
PK and a second table has a FK, then you will not be able to delete the
data
from the first table if matched data exists in the second table, as the
PK-FK link will prevent that.
You will have to remove the links before deleting data from the primary
table.

Wow, thanks All for the great suggestions
These users are out of state, so my pea brain was thinking of
Unload Data for Table
Delete Rows
Alter Table ...
...
Load the data back into the Table
But I will look at these other suggestions first.
I have done lots of Alter Tables in the past but this if the first time it
has nailed me. I guess I finally have a user
with enough data to reach a limit.
Thanks again

Marc,
I don't know if you run this code often, but I am assuming this is a one
time schema change.
If so, this bloating will happen when you make extensive schema changes.
Reload the database and all will be good. Also pack index.
Next time you do schema changes drop the indexes first, make the changes
and
re-create indexes.
Another suggestion which will avoid the bloating effect:
Unload the table structure and data (TravCard.all)
Edit TravCard.all and do your schema changes
Delete the table TravCard
Run TravCard.all.

p.s. Here is a small piece of code to get exact row size in a table.
set v vtable text=null
set v vsize int=null
CHOOSE vTable FOR #TBLVIEWS +
CHKBOX 1 +
TITLE 'Select table then click on [OK] button to continue' +
CAPTION 'Get Table Row Size' LINES 19 FORMATTED +
option TITLE_FONT_SIZE 10 +
|TITLE_FONT_NAME tahoma +
|BUTTONS_SHOW_GLYPH ON +
|THEMENAME razzmatazz
if vtable is null the
goto theend
endi
sel SYS_ROW_SIZE into vsize vi1 fro sys_tables whe SYS_TABLE_NAME=.vtable
set v vmsg text=('Table Row Size for'&.vtable&'is'&(ctxt(.vsize)))
pau 2 using .vmsg caption 'Find Table Row Size' icon confirm +
OPTION MESSAGE_FONT_NAME Tahoma +
|MESSAGE_FONT_COLOR 0 +

Hi
The RB2 file went from about 200 megs to over 800 megs all of the sudden?
It appears this block of code caused the problem,
My only guess is to put a Pack Table every so often to keep from hitting
this wall
Thanks
Marc
