Subject [jira] Created: (DERBY-3566) Alter column set data type not allowed in soft upgrade with unique constraint
Date Mon, 24 Mar 2008 16:15:24 GMT
Alter column set data type not allowed in soft upgrade with unique constraint
-----------------------------------------------------------------------------

                 Key: DERBY-3566
                 URL: https://issues.apache.org/jira/browse/DERBY-3566
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.4.0.0
            Reporter: Kathey Marsden
            Priority: Minor


In 10.3 I can do this:

ij> create table t0 (i int not null, v varchar(1) not null, constraint  uq unique(v,i));
0 rows inserted/updated/deleted
ij> alter table t0 alter v set data type varchar(2);
0 rows inserted/updated/deleted
ij>


In 10.4 soft upgrade mode I cannot:
ij> create table t0 (i int not null, v varchar(1) not null, constraint  uq unique(v,i));
0 rows inserted/updated/deleted
ij> alter table t0 alter v set data type varchar(2);
ERROR 42Z20: Column 'V' cannot be made nullable. It is part of a primary key or unique constraint,
which cannot have any
nullable columns.
