Hi Ricks, Thank you for your response.
Effectively when i execute select * from sys.sysschemas where schemaName = 'TESTEUR'; i obtain: 278b81cd-0155-d9ce-d86a-000012e9eb35 TESTEUR APP The authorized user for the schema is not Testeur. Yet, via netbeans services wizard, i have created the database BaseTestDroits with user name Testeur and a password and the result is a database with shema Testeur ( an also App) but the schema Testeur have app for authorized user. How can i connect as owner of database App? I have succeded like this 1) create a database with the netbeans wizard BddTest1 without user but a passwd ( admin ) 2) connect this data base with Netbeans services->databases->drivers-javadb(Network)->connect using set only the passwd admin 3) CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.user.uSCH', 'y'); create schema SCH authorization uSCH; CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.sqlAuthorization','true'); 4) RESTART SGBD SERVER and Connexion uSCH/y" 5) create table SCH.Client( numcli int primary key, nomcli varchar(30)); insert into SCH.Client values(1,'Dupont Jean'); insert into SCH.Client values(2,'Leroux Martin'); grant select on SCH.Client to pierre; 6) Connect to database without user but password admin 7) CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.user.pierre', 'z'); 8) Connect with pierre/z 9) select * from SCH.CLIENT NUMCLI NOMCLI 1 Dupont Jean 2 Leroux Martin Regards -- View this message in context: http://apache-database.10148.n7.nabble.com/lose-ownership-on-date-base-after-set-derby-database-sqlAuthorization-to-true-tp146429p146433.html Sent from the Apache Derby Users mailing list archive at Nabble.com.
