Alter column precision

[goyosito]

I'm working with DB2 ver. 8.x and I'm trying to change the precision of decimal(10) to decimal(20). My script is:

ALTER TABLE xyz
ALTER COLUMN campo SET DATA TYPE DECIMAL(20, 0);

but I got this error:

DB2 SQL error: SQLCODE: -104, SQLSTATE: 42601, SQLERRMC: ALTER TABLE xyz
ALTER COLUM;BEGIN-OF-STATEMENT;<values> [SQL State=42601, DB Errorcode=-104]

Please help me to understand what's wrong and how can I change the precision of my field.
Thanks

AFAIK Alter Column only works for Varchar in DB2. Hence you cannot alter a decimal column.
If this is urgent, then create a new table and move the data to the new table and then drop the old table.

Decimal data type can now be altered in v9.1 and above.
alter table <tablename> alter column <colName> set data type decimal(x,y).
You can only alter upto 3 columns and then you need to ReOrg the table.
