4.How to create tablespace ???"CREATE TABLESPACE" command.
3.How to retrive password if you forget of sql???
5.How to view the list of Users of a specific database???
6.How to know Users password information???All users and their encypted passwords are in the view dba_users. There's no way to get unencrypted passwords.
7.How to change from one user to another user with out exiting from the sql???Depends on what "the sql" means.
The SQL*Plus command CONNECT changes user and/or database, without exiting from SQL*Plus.

PLS-00201 when executing insexcpr.sql starter

Receiving a PLS-00201 on wwutl_htp.scriptclose when executing @insexcpr.sql with the suggested schema in the May PDK of starter. Followed the prior instructions. Also tried granting execute on wwutl_htp to starter.

Thanks Maxim & Rakesh, that worked.
It does look like a bug. The return on it's own works with other functions e.g. ASCII etc. but not ORA_HASH.
The select from dual version is painfully slow (e.g. 25 x times) though so I think I'll use dbms_utility.get_hash_value instead for now. I was planning to use that version in 9i anyway as my app still needs to run on 9i - but I was trying to get the ORA_HASH working for 10g as it is incredibly fast.
Will definitely log it though.

You will have to be a bit more specific about the error messages you get. Did you start the database and listener?

SQL 2005 Express will not start

Service just would not start after a reboot I have approximately 30 clients this has happened to basically out of the blue and they started happening approximately 6/17/2014. The SQL log and event log errrors are below. Uninstall reinstall only fails, switching
to local service account throws WMI Provider Error, Can't find object or property" [0x80092004]. The common issue seems to be a malware infection of Search Protect. Please advise before this gets worse. Thank you.

This is what I found by someone else;
I know it's probably too late to help with the original poster, but we had this same issue and nothing we tried resolved the problem. Finally, we opened a technical incident with Microsoft and this is the solution that we were provided:
Take backup of below registry key.
HKLM\SOFTWARE\Microsoft\Cryptography\MachineGuid This key should ideally have the GUID of the machine without curly braces, so {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} becomes xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Then delete the braces.
Try to reboot and start the SQL service . If service don’t start then Uninstall and reinstall SQL.
The above solution worked on two separate machines exhibiting this problem.

SQL Service with Domain Logon fails to Auto Start but starts Manually

I have set the SQL Service Logon to a Domain account. SQL Starts manually just fine, but it fails to start on reboot.
I see these four errors in the Windows System Log:
Event 1014 (Warning), DNS Client Events:
Name resolution for the name .... timed out after none of the configured DNS servers responded.
Event 5719, NETLOGON:
This computer was not able to set up a secure session with a domain controller in domain ... due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.
Event 1055, GroupPolicy:
The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).
Finally: Event 7000, Service Control Manager:
The SQL Server service failed to start due to the following error:
The account name is invalid or does not exist, or the password is invalid for the account name specified.
Apparently there is a delay between NETLOGON starting and "being aware" of the Domain. Apparently it still is not resolved by the time the SQL Service tries to start. However it is resolved by the time the user logs in, so SQL Service successfully
starts manually.
For various reasons I cannot make the SQL Service DelayedAuto. Is there any way to configure NETLOGON Service or DNS Client to not return from the Startup process untl the DNS is resolved?

A moderator can move it. I have no idea whether you can move it on your own. You can only delete your own post.
I would suggest that you repost manually to the Windows Server forum, so that you can change the title to something which fits better there. Maybe the text can also benefit from a review. Your original problem was that SQL Server does not start directly,
but you have already found out that you real issue is the DNS thing.

Creating PL/SQL function in SQL plus which will display desired output

Hello PL/SQL experts,
I am not skilled on PL/SQL so want you help for one of the PL/SQL requirement.
Requirement: We have a database purge jobs which deletes the records from our application database on daily basis. Our Client wants a verification PL/SQL to be created which they will run pre and post the purge job to identify the number of records deleted/processed by purge job. It should do a SELECT operation and find out the number of records in table based on the where clause and give the output to the user.
The result of PL/SQL should be something like this (considering the PL/SQL is processing multiple select statements):
****Verification SQL Start*****
30 records from table S_SRV_REQUEST selected
45 records from table S_SRV_REQUEST_X selected
15 records from table S_SRV_REQUEST_XM selected
*****Verification SQL complete*****
For this I am thinking of a simple PL/SQL which will diplay the count of records from each table but I am not sure how to display the count on screen as an output. Can I request PL/SQL experts to put some light on this?
Regards
Sumit

PL/SQL is a server side process running on your database server. It is not connected to a display or a keyboard, so cannot output any results from within the code itself.
What you need is a client application that the user can run which will query the database, or call procedure(s) to get results and then the client application will display those results appropriately.
One of the simplest client tools you can use to build such a user-friendly application is Oracle Application Express (APEX).
Bear in mind that if you're going to 'identify' record for deletion prior to actually deleting them, then you may also have a need to store the keys of those identified records somewhere so that only those records are deleted. Consider the situation where the user requests the information and the application queries the records to say there are 30 records from S_SRV_REQUEST with the correct criteria to be deleted. By the time the user confirms they are happy and want the records deleted, some other record(s) may have been updated and also meet the criteria, so just doing a delete based on the criteria itself could result in more than 30 records being deleted. However if you've identified the records and marked them in some way for deletion or stored the keys of those records on a queue somewhere to indicate the ones to be deleted, then your actual deletion process can just deal with those records and ignore any that have met the criteria since that time. Of course that depends on your individual requirements, but it's something to bear in mind.

Can some one please tell me what is the problem in the below pl/sql block

Hi, I have problem with the following pl/sql block, I need this with bulk operation.
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
-- upon successful validation insert the data into dept3, and emp3 interms of batches
-- I have give the sample example with dept and emp, but i have around 10 million records which has around 30-40 validations,
-- I would like to process them in terms of batches using bulk collection as this would do fast processing
-- Can some one please tell me how to insert them in terms of bulk with every set of 1000 records in each batch in this example,for every set of 1000 records
-- i need update batch id with unique number in dept table
-- with current data i can have 50 batches , I need to pass, deptno as parameter to my emp cursor.
-- can some one please tell me how to make this validation and insertion more efficient. so that while inserting the data for every batch it should insert batch id
-- Tried with LIMIT clause as well but not working
-- I am correcting the code as per your comments Request you to please suggest me so that I can correct , I am new to PL/sql, started learning now.

Hi, I have problem with the following pl/sql block
Well, as Hoek already said, that is the understatement of the century.
I can't be absolutely certain but I think that set of DDL and code that you posted has just about every possible error and design issue that there is! It would make an excellent addition to BluShadow's FAQs an an example of what NOT to do.
I don't think it is even possible to 'fix the basics first' as Hoek suggested. IMHO the first step needs to be to create a functional requirements document (FRD) that explains in detail WHAT needs to be done. That doc should also contain info about how any errors/recovery/restart is to be handled. It is premature to try to implement ANY solution without first knowing what is needed functionally.
Once the FRD is done you should do a walk-through based on your current architecture and sample data to make sure that the document really covers ALL of the steps that need to be performed and that it adequately explains how to deal with any processing or data issues that might arise.
The next document you need is the TRD - Technical Requirements Doc that covers the different technical implementions of the FRD that can be done and the advantages/disadvantages of each.
Then you can start working on a prototype.
1. The DDL you posted isn't coherent - there are CREATE table statements and then later ALTER statements that add additional columns. There doesn't appear to be any reason for not including ALL of the columns in the CREATE table statement.
2. You are using PL/SQL types instead of SQL types. That makes it impossible to use those types in SQL statements and makes it much more difficult to test since it is much easier to test a query in SQL (e.g. using sql*plus) that to embed the query in PL/SQL.
3. You are defining the same type twice but giving it different names.
TYPE dept_t
   IS
      TABLE OF dept%ROWTYPE
         INDEX BY binary_integer;
TYPE dept_i_t
   IS
      TABLE OF dept%ROWTYPE
         INDEX BY binary_integer;
Those are both based on the same DEPT table! Why the duplication?
Also you are using associative arrays instead of just using nested tables. Get rid of the INDEX BY clause.
4. You have some serious architectural and data model issues
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
Why would you do that? You say 'it has to update the header record ...'. Says who? That is just one indication that you are trying to implement a 'solution' before you have adequately defined the 'problem'.
Typically you would NOT alter any of the data tables; any validation errors/issues would get inserted into a table specifically designed to hold/log those issues. That table would contain key field values to correlate with the source of the error.
Those 'master' and 'child' entities are two SEPARATE things. Issues with a 'master' row have NOTHING to do with any possible child rows.
And issues with a 'child' row have NOTHING to do with any possible master rows. The ONLY connection between 'child' and 'master' is the foreign key that correlates them.
So you don't necessarily have to validate the 'child' rows in sync with their 'master' row. In many cases you would have a procedure that performs validation of the entire set of 'master' rows and log those issues/problems. You would use a different procedure to validate the entire set of 'child' rows and log their issues.
Those validation procedures can often work with ALL of the data using SQL statements instead of bulk processing.
5. You are using loop constructs that are not valid for the type of processing you are using
LOOP
    FETCH c1 BULK COLLECT INTO hdr_tbl;
    EXIT
WHEN c1%NOTFOUND;
END LOOP;
There can be NO exit since the bulk collect with either get EVERYTHING or NOTHING. Possibly that is just a holdover from your attempt to use the LIMIT clause but you removed that clause from the FETCH; I don't know.
There is so much wrong with what you posted it is really rather pointless to try to 'fix' it.
I suggest you start over and clarify and DOCUMENT the actual requirements without prejudice about the solution that someone seems to want to force on you.

Differences between ANSI SQL and Oracle 8/9

Hallo,
i'm looking for good online texts or books concerning the problem "Differences between ANSI SQL and different database implementations (ORACLE, Informix, MySQL...)" I want to check a program written in C (with ESQL) that works with an Informix-DB. In this code i want to find code that is specific to the Informix-DB. I want to change the database, so all the code should be independent from a DB. Does anybody know texts or books concerning this problem?
thx
Marco Seum

Basically there is syntax difference between both of them.
Lets say i want to join two table EMP and DEPT based on DEPTNO.
With Oracle SQL format its like this.
select e.*
from emp e, dept d
where e.deptno = d.deptnoHere the joining condition goes in the WHERE clause.
With ANSI SQL format its like this.
select e.*
from emp e
join dept d
on e.deptno = d.deptnoHere the join condition is mentioned separately and not in WHERE clause.
Oracle supports ANSI SQL starting from 9i version.
You can read more about the syntax difference Here

Duplicating Effort in SQL functions

Hi, If I have a piece of SQL such:
SELECT
      SUBSTR(really complex nested functions [no PLSQL function / context switching however]) AS COL1,
      LENGTH(SUBSTR(really complex functions [no PLSQL function / context switching however])
AS COL2
FROM mytableThe second column is obviously just the length of COL1
Does SQL engine when processing the function for COL2, execute the "really complex function" again - before getting the LENGTH? Or does it just reuse what it already calculated in COL1?
If not, is there anyway of allowing the "Really complex function" result resued by other COLs?
I do not wish to use a PLSQL function.
Thanks for any help

Well the CBO is pretty clever, it won't do two passes if it realises it's not necessary. Here's a bit of simple obfuscation SQL with and without inline view explained:

Set SPN for a local SQL Server 2008 R2 Express database used for local "Offline Mode" application

Hi - I have tried searching the web for tips on this situation. Basically, I am trying to recreate a previous employee's client Image. This image is used for one of our companies client application that features and "Offline Mode" where it connects
(Using Kerberos) to the local DB instead of the central DB server.
The custom image connects without issue. I cannot seem to recreate his configuration. I am sure of these things:
- Both images are using the same SQL Server 2008 R2 Express version.
- Both images have the same user accounts setup.
- Both images have "Remote Connections" setup with TCP/IP enabled in the Configuration Manager.
- Both images are joined to the same Domain server currently.
- Both images has the SQLServer service set to use "NETWORK SERVICE" account.
This is the error message I get when SQL starts up for the non-working image:
The SQL Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service. Error: 0x54b, state: 3. Failure to register an SPN may
cause integrated authentication to fall back to NTLM instead of Kerberos. This is an informational message. Further action is only required if Kerberos authentication is required by authentication policies.
Thank you for any assistance given.

Hi Gribbled,
Could you please change the SQL Server Service to run under 'LocalSystem' account and restart SQL Server? Then check if the error still occurs. When the SQL Server service account is configured to use the LocalSystem account, the server will automatically
publish the SPN.
Alternatively, to work around this issue, you can manually create the SPN for the SQL Server Service account using the SETSPN tool. For more details, please review this
blog.
Thanks,
Lydia Zhang

I am going to take the assesment test for ANSI SQL Programming before that i want to know any difference between ANSI SQL and ORACLE SQL?
I am studying for SQL but the test will be ANSI SQL please let me give an idea about the both.

Procedure not checking each sql statement.

Hi All,
I have created 2 tables names are A1 and B1. A1 table has some fields. Fields are no,sal,comm.,load_date. In A1 table NO (column) is the primary key.
Second table is B1. this table has id,phone_no and load_date. In this table constraint
ID column is the Not null.
After that I have created 2 procedures one for A1 and one for B1. with in those procedures I used SQL insert statements.
In procedures I used some valid sql statements and some invalid statements ( invalid statements means that I have specified constraint that’s why I specified duplicated and null values). While executing the procedures procedure shows error because of invalid statement and in that procedures I did not specify any Exceptions.
If I specify Exceptions in procedures executing successfully some records are not loading procedure is comeing out. How do we mention server needs to be check and every insert sql startement.
EX:
If I give 6 records from 1 to 3 valid statements. I mentioned 4 th record copy of previos record( duplicated). 5 th record and 6 th valid records.
Procedure executing successfully. Procedure loaded 1 to 4 records after that not loaded 5,6 and 7 records. How do we specify for record inserts 7. actually 7 th record is valid statement we should be insert this record. Please tell me how do we handle sql statements each and every one successfully or not.
create or replace procedure a_proc as
--declare
begin
insert into a1 values (100,2000,300,sysdate);
insert into a1 values(200,1000,400,sysdate);
insert into a1 values(300,3000,500,sysdate);
insert into a1 values(400,6000,600,sysdate);
insert into a1 values(400,900,700,sysdate);
insert into a1 values(400,10000,1200,sysdate);
insert into a1 values(900,11000,1300,sysdate);
commit;
EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERROR - '||sqlerrm);
end a_proc;
In B1 table colums are ID,PHONE_NO and Load_date. ID is not null column.
For B1 population I have created one procedure
create or replace procedure b_proc as
--declare
begin
insert into b1 values(1,123456,sysdate); -- 1 record
insert into b1 (phone_no,load_date) values (7896538,sysdate); --2 record
insert into b1 (phone_no) values(6763723458); ----3 record
insert into b1 (phone_no) values(453465778); --4 record
insert into b1 values(400,72894894,sysdate); --5 record
insert into b1 values(500,72894894,sysdate); --6 record
commit;
EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERROR - '||sqlerrm);
end b_proc;
if I execute above procedure procedure executing successfully but procedure inserting only first record not inserting 5th and 6th record. How do we exception for 5th and 6th records also.
Thanks and Regards,
Venkat

{color:#808080}{color:#333300}Hi,
Please find answer to your question below:{color}
Venkat: Procedure executing successfully. Procedure loaded 1 to 4 records after that not loaded 5,6 and 7 records. How do we specify for record inserts 7. actually 7 th record is valid statement we should be insert this record. Please tell me how do we handle sql statements each and every one successfully or not.
{color}
{color:#0000ff}Guna: The procedure hits an exception after 4th record, and does not process anymore as it exits out of the procedure, I believe the data is not committed as well. You need handle exceptions if the processing has to continue. Same is the belwo case as well

Any EVAL() equalant functions in SQL or PL/SQL

good day
i have 2 loops ,
outer loop has the real data from a table
and
inner loop has the column name to be selected from outer loop.
so in runtime, i need to select the columns dynamically .thats why i use inner loop. please see below.
for i in data Loop
for j in col_name Loop
--column name of data loop should be selected from this col_name loop.
dbms_output.put_line(i.||j.col_name);
End Loop;
End Loop;
But this should not work.
is there any eval function in plsql like in java and javascript to resolve this?
please advice.
thanks

> so in runtime, i need to select the columns dynamically .thats why i use
inner loop.
There are two basic approaches to dealing with dynamic projections. (projection = the columns and data types returned by a SELECT)
One is to use an interface that allows you, at run-time, to describe the projection. This is called a cursor's describe interface. In PL/SQL, that requires you to create a DBMS_SQL cursor. Details are in the [url
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sql.htm#sthref7370]Oracle® Database PL/SQL Packages and Types Reference guide.
The other approach is to deal with the projection as a collection. This is illustrated below. The two problems with this approach is that you must use the collection's constructor in the projection, and that you must deal with implicit conversions or hardcode explicit data type conversions.
