1. I defined a distinct data type 'Surrogate_Key' using the below
statement:
set current schema Myschema;
CREATE DISTINCT TYPE Surrogate_Key AS INTEGER WITH COMPARISONS;

2. Created a table that uses the above data type
CREATE TABLE COV_TYPE (
COV_TYP_DT DATE,
COV_ID Myschema.Surrogate_Key
);

Now, when I do a 'describe table COV_TYPE' it shows LENGTH 0 for 'COV_ID'
column.
As a result, I am unable to insert any data into this column. Any solution
to get around this issue??
Thanks.

Cheers,
San.

Looks like a bug in CLP. Do: DESCRIBE SELECT * FROM COV_TYPE
that works..
(Note that you can use the ADMIN_CMD() procedure to integrate DESCRIBE
into any SQL interface).

Here are the results for 'describe table' and 'describe select * from
twd_company'
What should i do? It does not allow me to enter data into the user defined
distinct types 'surrogate_key'.

db2 => describe table twd_company

ignore the mail above...
its working fine now, there was a RI issue due to which columns were not
being populated.
but i would still like the 'describe table' output to show INTEGER 4
rather than the distinct data type 'Surrogate_Key'.
Any solutions for this?

cheers,
sandeep.
