Problem in Automatically generated columns while copying schema

[Rahul B]

Hi,

I have a table where one of the columns is automatically generated as
a substring of values of some other column.
When i create a copy of that schema using sysproc.admin_c opy_schema,
the table goes in pending state, because the data in the table was
inserted fully and the column was not automatically generated(i think
this is the reason).

I tried to get it out of pending state by issuing "SET
Integrity...... ..." and Reorg table ......." commands.
But nothing worked.
I can't even delete data from that table, nor do a select or update.

So i had to resort to drop that table, and in turn drop a few procs/
funcs to drop that.
then recreate that table with DDL scripts, recreate other procs/
funcs.

Finally, i had to insert data like
"Insert into schema2.table(c ol1, col2........... ......col(n-1)) select
col1, col2, col3, .....col(n-1) from schema1.table"

so that the column n was automatically generated.

I am quite sure, this was only a workaround and not the correct way(I
am working in a dev database, and not a prod one, so, the workaround
was quite effective).

Can anybody please help as how to tackle the problem in a correct way?

Thanks

Rahul
