use of query rewriting

is there a way to connect the materialized views how often are accessible in general or by the query rewriting enabled option?

I would like to know what materialized views are useless, because they are never used by query rewrite.

You can follow with select audit, good example here

http://www.Oracle-base.com/articles/10G/auditing-10gR2.php

If you want to in retrospect you may need something cludge together by hitting the v$ sql and plans to even see who has several SQL identifiers have a plan that rewrite. not good enough.

How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.

How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.
For example:
If the user runs a query select deptno, avg (sal) from emp group by deptno;
We want the optimizer to use a hint of result_cache with this request, and it should be transparent to the user.
Query should be rewritten to seamlessly
Select / * + result_cache * / deptno, avg (sal)
WCP
Group of deptno;
How can this feature we make? Please advice.
I checked the possibility of SPM and contours, but it is not clear if this rewrite is possible here.

using reg query

Hello

I'm trying to use Reg Query to review the contents of a registry key. More precisely
- HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify
I just want to know what are the subkeys. I expect to be
- IconStreams and
  PastIconsStream
Since they are both of type reg_binary, when I do this query I have also all binary data as well, make very large output.

Is there a way to simply retrieve/request which is in the field/column name and not the column/field data ? I tried the /k options and /v who gave me errors, which I interpreted in the sense I was their use either wrong or they are not used in this instance.

There is not a lot of examples out there and most of repeat them what you find when you use /?.

Thank you.

The question you posted would be better suited in the MSDN Forums. I would recommend posting your query in the MSDN Forums.

Inserting data by using the query

Hello
In a book, I read the Sub statement:

Inserting data by using the query (DML)

If the user wants to transfer data from a table to another table in the insert statement are used independently of data that can be processed or not processed form.

Can someone clarify what is the significance of this (processed or unprocessed form).

Thank you.

Why don't you ask the author of the book.

How can we know what the author means when you take a quote out of context and don't provide any reference so that we can see exactly what is shown to you.

I can only imagine that they are referring to data that are queried directly, "like what", another table, or who was interrogated and manipulated before be inserted.

You cannot use the SQL commands that did not exist in the 8.0 database.

Oracle Forms (and reports) has a full PL/SQL engine and (only) the SQL parser.

However, form (and reports) PL/SQL engine / SQL parser is at a level that was in the Oracle 8.0 database.

Using the QUERY parameter in exp/expdp
Hi, I've faced a nite last question.
IM currently using Oracle 10 g (10.2.0.4) OS - MS Windows Server 2003

I want a dump of tables to export multiple schemas. say (acb.m1, pqr.b2, xyz.b1)

Each table has a minimum lines of 2,000,000,

And I want to just the initials 10 rows in each table of export

Is it possible that I can do this...

Please answer.
Thanks in advance
Export tables in multiple schemas is not supported in Data Pump until 11.1.0.7. So if you're on 10g, you will need to run multiple commands expdp. For only 10 lines of each table, use the query parameter

Query = "where rownum"<>

This will apply to all the tables you export.

I hope this helps.

By using the query table data pump
I am trying to perform an export of data pump on a table by using a query in a parfile and I'm getting a strange behavior. The database version is 10.2.0.4.3 and the AIX 5.3 operating system. The query looks like this.

QUERY = "POSDECLARATIONQUEUE:where SESSIONID in (select"B.SESSIONID"from POSACCOUNT A, POSDECLARATIONQUEUE B, POSDECLARATIONSESSION C, where"B.SESSIONID"="C.ID"and"C.ACCOUNTID"= 'A.ID' and 'Inform' = '10252')" "

This works, but gets 0 rows. If I run the query against the instance in a session of SQLPlus as below then I get 0 rows returned.

Select * from POSDECLARATIONQUEUE where SESSIONID in (select "B.SESSIONID" from POSACCOUNT A, POSDECLARATIONQUEUE B, POSDECLARATIONSESSION C, where "B.SESSIONID" = "C.ID" AND "C.ACCOUNTID" = 'A.ID' and 'Inform' = '10252');

If I take the columns all about apostrophes in the query on the Forum with SQLPlus, I get over 2000 rows returned.

SQL > select count (*) in the POSDECLARATIONQUEUE where SESSIONID in (select B.SESSIONID from POSACCOUNT A, POSDECLARATIONQUEUE B, POSDECLARATIONSESSION C where B.SESSIONID = C.ID and C.ACCOUNTID = A.ID and inform = 10252);

COUNT (*)
----------
2098

If I remove the apostrophes in the query parfile then I get the following error in data pump export.

DEU-00014: invalid value for the parameter, "schemas".

The PATTERNS option is not specified in parfile him and the TABLES option specifies that the table POSDECLARATIONQUEUE.

Can someone help with this, I can't seem to be able to get the syntax just to work within data pump.

Kind regards.
Graeme.

It seems that your query can be a little wrong:

That's what you have:

QUERY = "POSDECLARATIONQUEUE:where SESSIONID in (select"B.SESSIONID"from POSACCOUNT A, POSDECLARATIONQUEUE B, POSDECLARATIONSESSION C, where"B.SESSIONID"="C.ID"and"C.ACCOUNTID"= 'A.ID' and 'Inform' = '10252')" "

That's what I would have thought it should look like:

QUERY = POSDECLARATIONQUEUE: "where SESSIONID in (select B.SESSIONID from POSACCOUNT A, POSDECLARATIONQUEUE B, POSDECLARATIONSESSION C where B.SESSIONID = C.ID and C.ACCOUNTID = A.ID and inform = 10252).

You want to double "around the full query and you have not need single ' around all =." The single ' treat these values as strings and he said

"B.SESSIONID" = "C.ID".
the B.SESSIONID string is the string C.ID

In your query you used in sql has been

B.SESSIONID = C.ID

that said, it is that the B.SESSIONID stored value equal to the value stored at C.ID

Which is what you want.

IMPDP | Possible using the query option
HI PPL,

I wanted to know if IMPDP is possible by using the query option, as I took full expdp dump of the mentioned table and want to import only select lines.

Impdp arup/arup directory = demo_dir dumpfile = employees.dmp
Query = employees:------"" where salary\ > 10000\ order of salary "tables used ="

version: 10 gr 2
platform: UNIX

concerning
Obviously, it will be slow if you are using the query option, because IMPDP must import only the data that meets the criteria; It of why we export only limited data (one or two tables as needed) and import them completely.

Try to create parfile and use that, otherwise, you will need to escape each clause correctly to run exp or expdp successfully.

test.par

tables=emp
query="WHERE emp_no=123455"

or
tables=myobjects

If not, post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).
