Subject [jira] [Created] (DERBY-6432) INSERT/UPDATE incorrectly require user to have privilege to execute CHECK constraints on the target table.

------------------------------------

             Summary: INSERT/UPDATE incorrectly require user to have privilege to execute
CHECK constraints on the target table.
                 Key: DERBY-6432
                 URL: https://issues.apache.org/jira/browse/DERBY-6432
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.11.0.0
            Reporter: Rick Hillegas


According to the discussion on DERBY-6429, CHECK constraints run under the aegis of the constraint
owner and do not need to be checked when running INSERT/UPDATE statements. However, Derby
requires the INSERTer/UPDATEr to have EXECUTE privilege on functions invoked by CHECK constraints
and USAGE privilege on types mentioned by CHECK constraints.

Hopefully, this bug will be fixed by the work on DERBY-6429.

The following script shows this behavior:

connect 'jdbc:derby:memory:db;user=test_dbo;create=true';

call syscs_util.syscs_create_user( 'TEST_DBO', 'test_dbopassword' );
call syscs_util.syscs_create_user( 'RUTH', 'ruthpassword' );

-- bounce database to turn on authentication and authorization
connect 'jdbc:derby:memory:db;shutdown=true';
connect 'jdbc:derby:memory:db;user=test_dbo;password=test_dbopassword' as dbo;

-- schema
create function absoluteValue( inputValue int ) returns int
language java parameter style java deterministic no sql
external name 'java.lang.Math.abs';

create type hashmap external name 'java.util.HashMap' language java;

create function makeHashMap() returns hashmap
language java parameter style java no sql
external name 'org.apache.derbyTesting.functionTests.tests.lang.UDTTest.makeHashMap';

create table t1_check_function
(
    a int check ( absoluteValue( a ) > 100 )
);

create table t1_check_type
(
    a hashmap check( (a is not null) or (a is not null) )
);

-- data
insert into t1_check_function( a ) values -101;

insert into t1_check_type( a ) values ( makeHashMap() );

-- privileges
grant insert on t1_check_function to ruth;
grant update on t1_check_function to ruth;

grant insert on t1_check_type to ruth;
grant update on t1_check_type to ruth;

connect 'jdbc:derby:memory:db;user=ruth;password=ruthpassword' as ruth;

-- incorrectly fails because ruth does not have EXECUTE privilege on absoluteValue()
insert into test_dbo.t1_check_function values ( -102 );
update test_dbo.t1_check_function set a = -103;

-- incorrectly fails because ruth does not have USAGE privilege on hashmap
insert into test_dbo.t1_check_type values ( null );
update test_dbo.t1_check_type set a = null;
