i am trying to create a flight booking system,i am at the stage of creating the tables but am having trouble with creating one of the tables
CREATE TABLE Seat
(Seat_no NUMBER(3) CONSTRAINT PK_Seat PRIMARY KEY,
Class_Code CHAR(2) CONSTRAINT FK_Class_Code FOREIGN KEY (Class_Code) REFERENCES Class(Class_Code)
CONSTRAINTS CHK_Class_Code CHECK(Class_Code='EN' OR Class_Code='FS')
(Class_Code is a primary key in the table Class)
It comes up with an error saying ORA-02253: Constraint specification not allowed here and if i put a coma after the first constraint it says the name already used for an existing constraint.

ERROR: ORA-12534: TNS:operation not supported
Enter user-name:
so I Google around for the solution to the ORA-12534 error, one of the site,
[URL].......
here's my lsnrctl services
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521)) Services Summary... Service "MIKEXDB" has 1 instance(s). Instance "mike", status READY, has 1 handler(s) for this service... Handler(s): [code].....
The command completed successfully
right now I think I will be a fool to think that the solution is to resolve the ERROR: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor. so what is wrong with my setup, or is it some patch that I need to apply?
i am creating a library management system using struts 2.i have a form that display a table having column(bookname, author, publisher,..etc) and it contains an operation "edit book" with each row. now i m stuck with an update query(or any other query) by which i can edit an entire row (or any column) onclicking the edit button.i'm using oracle 10g database.
I'm trying to create a trigger that will come into play after the user has inserted a 0 for the booking evaluation, i need the booking id sent to the audit table. This is what I have tried so far:
CREATE OR REPLACE TRIGGER zero_evaluation AFTER INSERT OR UPDATE ON booking FOR EACH ROW WHEN (NEW.Evaluation=0) BEGIN INSERT INTO audit (audit_id, booking_id, Reason) VALUES (audit_id_seq.NEXTVAL,:NEW.booking_id, 'Contact customer for 0 evaluation'); END;
I get the following: Line 2 PL/SQL: SQL Statement ignored Line 3 PL/SQL: ORA-02289: sequence does not exist
This is my SQL statement: CREATE TABLE audit (audit_id numeric(5) not null, booking_id numeric(5) not null,
The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.
couple of questions about below parameters, do they measure single processor or avg usage across all processorss and cpus for example will i recieve alert if CPU system time goes above 95% for single processors? or not
CPU Idle Time (%) CPU System Time (%) CPU User Time (%)
My manager has a couple of 2-proc dual-core Opteron servers with 8GB of RAM and RAID controllers. These servers currently run Solaris 8, but he wants to migrate them to a newer Linux systems.
i have installed oracle 8i on my windows xp system. it has not given me any problems during installation. i could log on to oracle and work on it without any problems. but when i restarted my system, my system has failed to start the oracle service, and i could no longer logon to sql * plus.
I've got messages 'oracle not available'. i've even tried to start the service from administrative tools-services, but of no use. then i created a new database and log on to sql* plus. but when i rebooted my system, the problem continued.
I have a promotion table which is having 3 columns.
PROMOTION_ID
display_name
ASSET_VERSION This ASSET_VERSION
field keep on getting updated by other system where they may update the display name of the promotion_id.The main concept of this table is there will be a unique combitination of asset_id and promotion id.
Promotion_idDISPLAY_NAME ASSET_VERSION 123 1ST VERSION 1 123 2ND VERSION 2 123 3RD VERSION 3 456 1ST VERSION 1 456 2ND VERSION 2 456 3RD VERSION 3 789 1ST VERSION 1 789 2ND VERSION 2 789 3RD VERSION 3
So,my requirement is that i have the fetch promotion_id ,display_name that is having highset asset_version.
When I attempt to connect to the DB as SYS, SYSTEM using sqldeveloper I get:
ORA-01017:invalid username/password; logon denied
Now I am certain the username and password are correct, I think it has something to do with remote login of SYS account. Are DBA accounts not allowed to connect via network? I get the same error when I try to sqlpython wrapper which I believe uses TCP
[oracle@oracle ~]$ sqlpython sys as sysdba which: no gedit in (/u01/app/oracle/product/11.2.0/db_1/bin:/usr/sbin:/sbin:/bin:/usr/sbin:/usr/bin) which: no kate in (/u01/app/oracle/product/11.2.0/db_1/bin:/usr/sbin:/sbin:/bin:/usr/sbin:/usr/bin) Password: Connection failure. Opens the DB connection. Some sample valid connection strings: [code]....
As per my req, i need to get the system grants of one user (GRANTEE) using DBMS_OUTPUT API. The requirement get completed using 'SYSTEM_GRANT' as parameter for OPEN function in the metadata api. Please look into part of code which works.
The second set filter doesn't work to get SYS GRANTS of one user. It does not throw any error. Simply the filter doesn't work. 'GRANTEE_EXPR' is not a correct value in the 2nd set filter. What parameter need to pass in object_path_expr ('GRANTEE_EXPR')?
In the article regarding gathering CBO Statistics, it states: QUOTE When an Oracle database is created, a job will be scheduled that will generate the database statistics for you. You will still need to collect system statistics however, as these are not collected by the automatic statistics gathering mechanism.
what is the difference between "database statistics" and "system statistics"? In other words, do I need to run this script for each schema owner in my 10g/11g instance?
variable whoami varchar2(20); begin select user into :whoami from dual; end; exec dbms_stats.gather_schema_stats( - ownname => :whoami, - options => 'GATHER AUTO', - estimate_percent => 15, - cascade => true).
We need to connect to an Oracle database from an ASP web page and I downloaded and installed ODAC112021.zip to a Window 2003 server; can connect OK I sent the zip to co-worker in another state and he installed it on slightly older build of 2003 server and we get the following error
"The setup routines for the Oracle in OraClient11g_home1 ODBC driver could not be loaded due to system error code 14001"
Only saw one post on OTN discussion and msot mention another error (998) [URL]

In my database ,the size of the system tablespace is 1024M.now i found its free space is 477.875M.
SQL> SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024 M FROM DBA_FREE_SPACE where tablespace_name = 'SYSTEM' GROUP BY TABLESPACE_NAME ; TABLESPACE_NAME M --------------- ------- SYSTEM 477.875
In system tablespace ,the max size segment is IDL_UB1$,it is 167M
