Enforce date datatype in oracle 11g

Can I restrict database so that application can not enter date data in certain format.
E.g. If I want that date enter should be registered in [year to minute] 'MM-DD-YYYY' hh:mm' only format and not in [year to second format]'MM-DD-YYYY' hh:mm:ss' then how I can do it in Oracle 11g.
Currently I am using oracle sql developer to create data model and then I want to generate DDL from that to generate database. Is there is any facility in Oracle SQL developer to enforce format specification.
thanks!

This is not really related to SQLDeveloper, so you may find better answers in another forum but I'll try to give you an idea anyway.
Actually the DATE datatype has no format, you use a format when you convert it to a string or vice versa, but the DATE itself is just a DATE.
You could probably create a trigger to truncate your data as you see fit, but IMHO your best option would be to remove the seconds from your output queries using something like
TO_CHAR(YOUR_DATE_FIELD,'MM-DD-YYYY HH24:MI')you can also set this output format for SQLDeveloper in
Tools -> Preferences -> Database -> NLSbut this will work only for SQLDeveloper, it's up to you to determine the best way of setting the output/input date format in your specific application.

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

Hi there
you have date data type in Date_Of_Birth you have to use to_date function
try this
select case((Date_Of_Birth)when to_date('01/01/1900', 'DD/MM/YYYY')
then ''
ELSE TO_CHAR(Patient.Date_Of_Birth, 'DD/MM/YYYY')
END Date_Of_Birth

Date datatype in Oracle 8i

Books tells me that Date datatype is stored as 7 bytes.
Yet when I run the following query, result is 8. Can someone explain this.
SQL> select vsize(sysdate) from dual;
VSIZE(SYSDATE)
8

It would appear that the external representation of a date is different than the stored representation of a date. Consider:
SQL> CREATE TABLE t (dt DATE);
Table created.
SQL> INSERT INTO t VALUES(sysdate);
1 row created.
SQL> COMMIT;
Commit complete.
SQL> SELECT DUMP(dt) from t;
DUMP(DT)
Typ=12 Len=7: 120,102,12,30,10,27,9
SQL> SELECT DUMP(sysdate) FROM dual;
DUMP(SYSDATE)
Typ=13 Len=8: 7,210,12,30,9,27,18,0
SQL> SELECT DUMP(TO_DATE('20021230','yyyymmdd')) FROM dual;
DUMP(TO_DATE('20021230','YYYYMMDD
Typ=13 Len=8: 7,210,12,30,0,0,0,0
A stored date is type 12 and has length 7, while sysdate, and the result of a to_date call is type 13 and has length 8. This seems to be true in all versions of Oracle I checked (7.3.2, 8.0.5, 8.1.7, 9.0.1)

How to generate TPC-E schema/data sets in Oracle 11g

Hi,
I want to use TPC-E schema in my Oracle 11g database (Standard) and also want to use DATA SETS from this benchmark for some kind of testing.
I've download EGen v1.8.0 from this TPC website:
http://www.tpc.org/tpce/default.asp
but don't know who to implement this benchmark database into my computer's database. I'll appreciate if someone please suggest me how to do this...
Thanks alot.

I want to find Optimal size of a data block size as this is the one parameter which can increase the performance of a database or decrease it.If there is a single optimal size, that would surely be the default Oracle block size - as Oracle should know perhaps better than any of us, just what block size differences do as it is their code that uses it?
Can I ask why you said that you would not have chosen this topic as a thesis?My leaning has always been to expert systems and A.I. Even designed and written my own expert system language years ago. One thing that is critical in such systems is how you structure data - and that has a nice database angle to it. One that I believe can still be exploited for research purposes.
Don't you think that it'll benefit DBA's or database developer after I reach a successful conclusion?To be honest, in the real world of database systems, the least of my concerns are data block sizes. For example, we're busy putting together a storage array that should have a maximum I/O pipe size of 40Gb. In comparison, we currently use dual 2Gb fibre channels on most of our servers for our I/O.
Technology moves fast. And perhaps there is an ideal block size for the standard storage array and Oracle instance today - but that could invalidated by new technology next year. Would I want to spend time and effort studying and analysing and researching a very specific technical subject, that perhaps is not considered as of that critical importance by DBAs and perhaps can be outdated with new technology and techniques?
I honestly do not want to put you off studying db block sizes. Perhaps there's still some critical issues to uncover in that respect. But personally.. there are many other subject areas in database technology that peak my interest a lot more. But then you have your personal preferences and likes and dislikes - and data blocks could be your muse. :-)

Failed to get Column's data type in Oracle 11g

Hi,
I made an ADO connection(Oracle provider) to Oracle 11g, and use ADO API: OpenSchema(adSchemaColumns) to fetch the columns' info. But I found I couldn't get the column's data type if it's type is timestamp or timestampwithtimezone in database. What I got is 'adIUnknown' whose number is 13.
I test with another column whose data type is 'date', and everything is ok. I get the data type 'adDBTimeStamp'.
This issue occurs on Oracle 10g, too.
Can anyone offer some help? Thanks a lot!

Anyone inserted data directly from Oracle 11g to MySQL?

Hi There,
We work mainly on Oracle 11g. However, there is a requirement to now connect to an external MySQL database from our company's Oracle Database. Would be trying to do this for the first time. The process would be to download the data using PL/SQL from the ORacle 11g DB and then insert the data into the MySQL DB table. Had a few questions,
1. Are there any known issues with connections between ORacle as source and MySQL as target. Anything that needs to be kept in mind?
2. How do we send the data to MySQL, I mean in PL/SQL we can have the procedure create the insert statements. But can we directly fire the insert on MySQL ? If yes, any suggestions on what the commands would be?
3.Any way to figure out if the insert was successful?
4. We might also have to do other operations like update/delete etc.
5. Any possible reference or sample code on this would also help.
Thanks

Well, the simplest and most direct approach would be to create a java function in the database to perform the operation and call it from pl/sql. I've done it before and there are examples out there and its a pretty straight-forward process.
A quick example from [this website|http://w2.syronex.com/jmr/edu/db/oracle-and-java]
import java.io.*;
import java.sql.*;
public class OraThin {
public static void main(String[] args) {
    try {
      Connection con=null;
      Class.forName("oracle.jdbc.driver.OracleDriver");
      con=DriverManager.getConnection(
        "jdbc:oracle:thin:@machine_name:1521:database_name",
        "scott",
        "tiger");
      Statement s=con.createStatement();
      s.execute("
        INSERT INTO BOOKS VALUES
        'A Tale of Two Cities',
        'William Shakespeare',
        4567891231,
        '5-JAN-1962'
      s.close();
      con.close();
   } catch(Exception e){e.printStackTrace();}
}Check out Oracle's Java tutorial at http://docs.oracle.com/javase/tutorial/jdbc/basics/storedprocedures.html for more in-depth information.
If you're going to be doing this for more than a handful of tables under very controlled circumstances keeping it synchronized is going to be a mess, however.

Question related to CLOB data type in Oracle 11g

Hi,
I'm trying to assign a string value to a CLOB variable but it is giving me an error as described below. Can someone please let me know what am I missing here? As far as I know, in 11g a CLOB variable can store upto 4GB of data and all i'm trying to use is only 7K of data.
DECLARE
v_sql1 CLOB;
v_sql2 CLOB;
BEGIN
DBMS_OUTPUT.ENABLE(1000000);
v_sql1 := 'BLAH-BLAH-BLAH.........'; --> this string is actually more than 4000 characters.
v_sql2 := TO_CLOB('BLAH-BLAH-BLAH.........'); --> this string is actually more than 4000 characters.
dbms_output.put_line(v_sql1);
dbms_output.put_line(v_sql2);
END;
When I try to execute the above script, I get the error message: ORA-06502: PL/SQL: numeric or value error:character string buffer too small.
I even tried to use TO_CLOB function as shown above but it is failing as well.
NOTE: The string to assign is not coming from any table but mainly a SQL statement used for sys_refcursor.
Thanks.

Table move after data deletion in oracle 11g

Hi,
Our previous system was in oracle 9i, And we used to archive our data in every 1 year which caused a huged number of DML operation our database. After that,we used to move our table and rebuild indexes to releases spaces. After Upgradation ,our presence system is running on oracle version 11.2.0.2. Now my question do we need to move table in 11g to release space?? Or it automatically done in 11.2.0.2???
Thanks and Regards,

Now my question do we need to move table in 11g to release space?? Or it automatically done in 11.2.0.2???If you move that space will be released from those extents but you wont gain any space at OS level until unless you shrink datafile. Move command will do the job.
did you see what is the free space in tablespace after moving objects?

Date Format in Oracle 11g XE

Hello everyone,
I have installed Oracle11XE and noticed that it has the following date format:
      SQL> SHOW PARAMETER NLS_DATE_FORMAT
      NAME                                 TYPE        VALUE
      nls_date_format                      string      RR-MM-DD
I know that I can change the format for the session, like this:
     alter session set nls_date_format = 'DD-MON-YY';
I also know that to change the system parameter I need to do the following:
     alter system set nls_date_format = 'DD-MON-YY' scope=spfile;
     then restart the database.
However, after I do the latter, the date format is still:
     SQL> select sysdate from dual;
     SYSDATE
     14-11-19
Could someone tell me why this is happening and correct this?..
Thanks.

Space utilization and optimal row size in Data Blocks in Oracle 11g

Hi,
My main concern till now is to find the Optimal no. of rows/tuples per one oracle data block of size 8192. For that purpose i'm doing different kind of testing.
I created one table:
SQL> create table t5
2 (x char(2000));
Table created.
Inserted 4 rows in it.
Queried to check in which block no's these 4 rows exist.
SQL> SELECT x,DBMS_ROWID.ROWID_BLOCK_NUMBER(rowid) "Block No."
2 from t5;
x Block No.
A 422
B 422
C 422
D 423
SQL> analyze table t5 compute statistics;
Table analyzed.
SQL> select LOGGING,BACKED_UP,NUM_ROWS,BLOCKS,EMPTY_BLOCKS, AVG_SPACE,CHAIN_CNT, AVG_ROW_LEN
2 from user_tables
3 where table_name = 'T5';
LOG B NUM_ROWS BLOCKS EMPTY_BLOCKS AVG_SPACE CHAIN_CNT AVG_ROW_LEN . YES N 4 5 3 6466 0 2006 .
8 data blocks are initially allocated. but my question is that while creating table of even small sizes, every time i'm seeing that it shows BLOCKS (used) are 5.
why 3 block are EMPTY_BLOCKS allocated all the time?
AVG_SPACE is the FREE space in every BLOCK that is used if i'm not wrong?
In this scenerio 3 rows (each of around 2006 bytes) are inserted into into one BLOCK of 8192 i.e. 8192-6006=2186. 2186 is the PCTFREE or what?
How can I see this CHAIN_CNT column value other than 0?
How can actually I find the optimal no. of rows/tuples in 1 data block that will not increase OVERHEAD on the system.
I'll highly appreciate the genuine help and solid suggestions.
Thanks in Advance.
Best Regards,
Kam

Looking for Active Data Guard in Oracle 11g Release 2 References

I want to reach out to customers who have implemented Active Data Guard in production (preferably 11.2), so that we can develop some
customer references that in turn will benefit other customers. The customers who get selected for such references may further be selected to publish their case study directly in oracle.com and/or invited as a customer co-speaker in the upcoming Oracle OpenWorld at San Francisco (Sep 19-23, 2010). Being a customer co-speaker at OOW means they get a free pass to the full conference (regular price for that is $1795-$2495).
Please send any follow-ups to [email protected]
Thank you.
