Marc,

 

That's the way it is.  Whenever you issue an ALTER TABLE command, R:BASE
renames the table, makes the change then, in effect, projects the result
into a new table.  The original, renamed table is removed from the schema,
but the space it consumed remains consumed until you do a PACK or RELOAD.

 

Do a LIST and note where your table falls in the list.  Now do an ALTER
TABLE followed by another LIST.  Unless your table was the last on the list
to begin, it will be elsewhere in the list.  That is a visual clue as to
what is going on behind the scenes.

What a mess!  Unfortunately this is a permanent table with over 13,000 rows.
Such a simple change sure can cause major pains.

 

Thanks for the tip

Marc

 

 


 

3. If this is permanent, prexisting data, make a temporary table with
different column names and the longer field sizes.  Then append the data to
the temporary table, delete the data from the real table, do the ALTERs, and
append the data back from the temporary table to the real one.

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

 

 

-- there is only 300 rows in this table

 CREATE INDEX v1 ON `spbutton` (`NewButName` ASC )

 CREATE INDEX v4 ON `spbutton` (`V4` ASC )
