Subject Re: [jira] Created: (DERBY-1724) Executing grant statement within a transaction leads to a NPE later when the db owner attempts to update a table
Date Fri, 18 Aug 2006 11:48:44 GMT
Hi Yip,

I am a newbee to Derby and I was trying to reproduce the error by 
following the steps you mentioned. Before I could reproduce the problem, 
I encountered another error i.e.:

ij version 10.2
ij> connect 'jdbc:derby:test;create=true' user 'user1' as user1;
ij> CALL 
SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.sqlAuthorization','true');
0 rows inserted/updated/deleted
ij> connect 'jdbc:derby:test;create=true' user 'user2' as user2;
WARNING 01J01: Database 'test' not created, connection made to existing 
database instead.
ij(USER2)> connect 'jdbc:derby:test;create=true' user 'user3' as user3;
WARNING 01J01: Database 'test' not created, connection made to existing 
database instead.
ij(USER3)> set connection user1;
ij(USER1)> create table tbl1(c varchar(1));
0 rows inserted/updated/deleted
ij(USER1)> insert into tbl1 values 'a', 'b', 'c';
3 rows inserted/updated/deleted
ij(USER1)> autocommit off;
ij(USER1)> grant select on tbl1 to user3;
ERROR 42Z60: GRANT not allowed unless database property 
derby.database.sqlAuthorization has value 'TRUE'.

Can you please provide some input for how to set the property 
"derby.database.sqlAuthorization" to true.

Thanks in advance,
Saurabh
