Internal XML to the query with join

I have a CF page that reads an XML file in a query using < cffile > XMLParse and QueryAddrow.

I then do a QoQ on the result and voila! I have my page. I hide the query for 8 hours and the XML file is only reread this cache expires. It works well.

My problem now is that the file contains data from three tables of database instead of one, so I need to make an inner join on the tables. But I can't do a t/t with an inner join.

Does anyone know a way for me to do this?

Oh, didn't know that. How about interweaving of QofQ? Join Query1 and Query2 requests in a new query, then join for 3 statement?

Rewrite the query with joins, and group by

Hello

It's an interview question.

Table names: bookshelf_checkout
virtual library

And the join condition between these two tables is title

We need to rewrite under request without using the join condition and group by clause?

SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
           FROM bookshelf_checkout bc,bookshelf b
           WHERE bc.title(+)=b.title
           GROUP BY b.title;

When I was in College, I read most of SELECT statements can be replaced by operations base SQL (DEFINE the OPERATORS). Now, I am rewriting the query with SET operators, but not able to get the exact result.

Kindly help me on this.

Performance issue with the query when join OKS and tables of the IB

Hello
I'm developing an integration for the automation of RMA through repair. The type of repair order is based on the details of the guarantee. This check must be made for each record.
Request for detailed below, I wrote, but it of a long way and slows down my program. Without this validation, it works perfectly.

Need help in the optimization of the query with the Group and joins by clause

I'm having the problem by running the following query... It takes a lot of time. To simplify, I added the two tables FILE_STATUS = stores the file load details and COMM table Board table job showing records treated successfully and which was communicated to the other system real. Records with status = T is trasnmitted to another system and traansactions with P is waiting.

CREATE TABLE FILE_STATUS
(FILE_ID VARCHAR2(14),
FILE_NAME VARCHAR2(20),
CARR_CD VARCHAR2(5),
TOT_REC NUMBER,
TOT_SUCC NUMBER);

CREATE TABLE COMM
(SRC_FILE_ID VARCHAR2(14),
REC_ID NUMBER,
STATUS CHAR(1));

INSERT INTO FILE_STATUS VALUES ('12345678', 'CM_LIBM.TXT', 'LIBM', 5, 4);
INSERT INTO FILE_STATUS VALUES ('12345679', 'CM_HIPNT.TXT', 'HIPNT', 4, 0);

INSERT INTO COMM VALUES ('12345678', 1, 'T');
INSERT INTO COMM VALUES ('12345678', 3, 'T');
INSERT INTO COMM VALUES ('12345678', 4, 'P');
INSERT INTO COMM VALUES ('12345678', 5, 'P');
COMMIT;

Here's the query I wrote to give me the details of the file that has been loaded into the system. He reads the table of State and the commission files to display the name of the file, total records loaded, total at the table of the commission and the number of records which has finally been passed successfully loaded (Status = T) with other systems.

SELECT 
    FS.CARR_CD 
    ,FS.FILE_NAME 
    ,FS.FILE_ID
    ,FS.TOT_REC
    ,FS.TOT_SUCC
    ,NVL(C.TOT_TRANS, 0) TOT_TRANS
FROM FILE_STATUS FS
LEFT JOIN
(
    SELECT SRC_FILE_ID, COUNT(*) TOT_TRANS
    FROM COMM
    WHERE STATUS = 'T'
    GROUP BY SRC_FILE_ID
) C ON C.SRC_FILE_ID = FS.FILE_ID
WHERE FILE_ID = '12345678';

In production, this request has several joins and takes a long time to deal with... the main culprit for me is the join on the COMM table to count the number of number of transactions sent. Please can you give me tips to optimize this query to get results faster? What I need to delete the Group and use the partition or something else. Help, please!

Don't know if it will be faster based on the information provided, but analytical functions offer an alternative approach;

select carr_cd, file_name, file_id, tot_rec, tot_succ, tot_trans
  from (select fs.carr_cd,
               fs.file_name,
               fs.file_id,
               fs.tot_rec,
               fs.tot_succ,
               count(case
                        when c.status = 'T' then
                         1
                        else
                         null
                      end) over(partition by c.src_file_id) tot_trans,
               row_number() over(partition by c.src_file_id order by null) rn
          from file_status fs
          left join comm c
            on c.src_file_id = fs.file_id
         where file_id = '12345678')
 where rn = 1;

How to optimize the query with a join of virtual tables
I'm working on a query that is get the data of virtual tables 2 and b
one is formed by the Union, all say 4 queries and b is formed by the Union, all say 3 queries
then these two virtual tables and b are joined on a column common and data are extracted from their part.
Problem is that there is about 1 minutes each in the two virtual tables has and b. If individual a and b queries virtual takes about 5 seconds to retrieve data
but the join on column takes about 25 seconds to retrieve data.
Can someone guide me how to optimize the recovery of joining 2 virtual tables having large data

As Odie post pointed out. The first (x 1) XMLTable retrieves the content of ProcessRequestRequest and by doing this, delete the CDATA tag. We now have a CLOB that resembles XML. The second XMLTable (x 2) converts this CLOB into an XMLType and looking for the node that matches the XPath expression. It's where I've hardcoded in your query to search for a specific node. As you want node has a repeated structure that you want to retrieve each row, I spent structures repeatedly in the third XMLTable (x 3) so he could analyze. You could combine x 2 and x 3 using XQuery, but I suggest starting by this method I found that it's easier to understand what is happening.

To test out your code, simply replace the line

by the way XML_VAR

with

from XMLTYPE ("... the content of the SOAP Message...")

and run the query. You can do this to debug the query as you and just do a SELECT * to see what all went from XMLTable to XMLTable, so went to check the correct data.

Combine two results of the query with rank

Dear all,

Published by: Valerie good-natured April 18, 2011 02:54

Employee no. 100 has no manager_id, so you need an outer join:

select first_name|| ' '||last_name Name,
Manager,Department from employees e,
(select first_name||' '||last_name Manager,employee_id,first_name first from employees) m ,
(select department_name Department,department_id from departments) d where
e.manager_id=m.employee_id (+)
and e.department_id=d.department_id (+)
start with e.employee_id=100 connect by e.manager_id=prior e.employee_id;

Hope this helps,

The mentioned below query takes about 10 hours to complete (10.2.0.4).

There are 3 tables (table t has a relationship 1: n with table e and k table also has a relationship 1: n with table e).
Table a contains 200,000 lines. (this table is truncated and inserted several times a week)
E table contains rows of 1Mio.
K table contains rows of 170Mio.

drop table t;
create table t
(
   t_id number,
   constraint t_pk primary key (t_id)
);

drop table e;
create table e
(
   e_id number,
   e_doc nvarchar2(16),
   e_date date,
   constraint e_pk primary key (e_id)
);

drop table k;
create table k (
   t_id number,
   e_id number
);

create unique index k_i1 on k(t_id, e_id);

exec dbms_stats.gather_table_stats(user, 'T');
exec dbms_stats.gather_table_stats(user, 'K');
exec dbms_stats.gather_table_stats(user, 'E');



-- Sample data:

insert into t(t_id) values (100);
insert into t(t_id) values (101);
insert into t(t_id) values (102);
insert into t(t_id) values (103);


insert into e(e_id, e_doc, e_date) values (200, 'doc 200', to_date('01.01.2010', 'DD.MM.YYYY'));
insert into e(e_id, e_doc, e_date) values (201, 'doc 201', to_date('02.01.2010', 'DD.MM.YYYY'));
insert into e(e_id, e_doc, e_date) values (202, 'doc 202', to_date('03.01.2010', 'DD.MM.YYYY'));
insert into e(e_id, e_doc, e_date) values (203, 'doc 203', to_date('04.01.2010', 'DD.MM.YYYY'));

insert into k(t_id, e_id) values (100, 202);
insert into k(t_id, e_id) values (100, 203);

insert into k(t_id, e_id) values (101, 203);
insert into k(t_id, e_id) values (101, 204);





select k.t_id, e.e_date,  e.e_id, e.e_doc
from   e, k, t
where  k.e_id = e.e_id
and    k.t_id = t.t_id
order by k.t_id, e.e_date desc;


      T_ID E_DATE         E_ID E_DOC
---------- -------- ---------- ----------------
       100 04.01.10        203 doc 203
       100 03.01.10        202 doc 202
       100 02.01.10        201 doc 201
       100 01.01.10        200 doc 200
       101 05.01.10        204 doc 204
       101 04.01.10        203 doc 203

I need a query that takes the latest 3 posts for a given t_id:

      T_ID E_DOC_LIST
---------- -----------------------
       100 doc 200/doc 201/doc 202
       101 doc 203/doc 204


Sample query:

select t_id, e_doc_list
   from (
   select  k.t_id,
        row_number() over(partition by k.t_id order by k.t_id, e.e_date desc) r_num, 
        rtrim(       lag(e.e_doc, 0) over(partition by k.t_id order by k.t_id, e.e_date) || 
              '/' || lag(e.e_doc, 1) over(partition by k.t_id order by k.t_id, e.e_date) || 
              '/' || lag(e.e_doc, 2) over(partition by k.t_id order by k.t_id, e.e_date), 
              '/') e_doc_list
     from  e,
           k,
           t
     where  k.e_id = e.e_id
     and    k.t_id = t.t_id
     order by k.t_id, e.e_date desc
) where  r_num = 1   ;


      T_ID E_DOC_LIST
---------- --------------------------------------------------
       100 doc 203/doc 202/doc 201
       101 doc 204/doc 203

The example query takes several hours in production.
The r_num = 1 filter is applied quite late. Is there another way to generate the query or even review the tables.

You could be in one of the rare cases where the index should be rebuild, take a look in the following thread:
http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6601312252730 #69571308712887 (search for 'index of Sweeper')
Make sure that you have checked if you are in this case before going for an expensive index rebuild.

Run the query with multiple parameters

Dear
Motion code below for the data is of per_all_people_f, who works for only one setting, when I pass 2 parameters, then is to take the last of them fail times two, could you pls advice how it both join in where clause.

You may need to change the START_DATE whereclause as below:

WhereClause = WhereClause + ("START_DATE = TO_DATE (:" + (++ bindCount) + ', "MON-DD-YYYY" ") AND" ' ");

Note:-need to specify the correct format.

Select the query with the level line list where the clause
Hi all

I am creating a tabular presentation based on a SQL query that has a list of selection based on a query with a where clause clause that refers to a column in the original SQL query.

The situation is, I have a table that stores the client_id, source_id, and build_id, lets call it client_source. I have a second table, build_source, containing source_id and build_id, one to many relations between the two (1 source_id could have build_id 1-7).

Using a tabular presentation, I want to select the correspondent build_id to use in client_source, but the selection list should contain only the build_id for this particular source_id of lines.

Here is an example of the SQL source of tabular presentation;

Select
s.ROWID,
s.CLIENT_ID,
s.SOURCE_ID,
APEX_ITEM. SELECT_LIST_FROM_QUERY (1, s.BUILD_ID,)
"Select display b.build_id, b.build_id return.
b build_source where b.source_id = s.SOURCE_ID ') lst
of s client_source

what I want to achieve, it's as source_id "BOLD" match fields. When the query is built this way, I get an error of "invalid identifier" Oracle on s.SOURCE_ID during execution.

Is there some special tags to be used to refer to the external column? I must be missing something because this looks like a pretty mundane problem.

I am running on 4.1.0.00.32, on an Oracle 10 g release 10.2.0.4.0 Server Express request.

I look forward to useful responses!

See you soon,.
Jason

Your selection by query list receives a static SQL. That SQL can't "see" the value of your s.source_id.
But it would work like this:
where b.source_id = ' | s.SOURCE_ID)

You would be the value for the SQL concatenation. It is not ideal, but it will work.

How to transpose the query with the following result
Dear all,

Can someone tell me a method to convert my query result

Details are provided in

http://obiee11ge.blogspot.com/2010/07/how-to-transpose-query-with-following.html

Concerning

Mustafa
Hello

Try this
Create a request combined with,

criterion no. 1: model, revenue (Actual), Cogs (Actual), Opex (Actual), PL (Actual)

in the dummy column fx enter the "Real" value

criterion 2: model, revenue (Yago), Cogs (YAgo), Opex (Yago), PL (Yago)

in the dummy column fx enter the value as "Yago".

criterion 3: model, revenue (Budget), Cogs (Budget), Opex (Budget), PL (Budget)

in the dummy column fx enter the value as 'Budget '.

Now go to the columns of result and set names coumn (revenue, COGS, Opex, PL) for the result set.
For the Dumny, remove column header.

In a sheet view, you will get the result.

Thank you

Report with the query with union and parameters
Hello

We have an obligation to create a report with the request, which is the union and parameters.

I intend to create a database for the report based on a query. But the problem here is that the way to pass parameters in the query.

Request is something like that

Select x.a, x.b, x.c
x
where x.year =: para1
and x.status = 'A '.
Union of all the
Select x.a, x.b, x.c
x
where x.year =: para1 - 1
and (x.status = 'c' and x.date =: para2 or x.status = 'I' and x.date < =: para2)

Here x.year in the first select statement must be equal to: para1 and second select statement, it should be: para - 1.

How this requirement can be achieved?

Client don't want to separate worksheet, a parameter and another for the actual data that I tried with sys_context and it worked. But the client wants the result in a single sheet only... So I need to change their approach.

Help, please.

Thank you
Hello
Another option is to convert the request so that you will have the items from the selection
for example on the query you provided that you can use:

Select 'Curr' rec_type, x.a, x.b, x.c, x.year, x.date, x.status
x
where x.status = "A".
Union of all the
Select 'Prev' rec_type, x.a, x.b, x.c, x.year, x.date, x.status
x
where x.status in ('c', 'I')

then, in the workbook, you will be able to create conditions such as:
rec_type = 'Curr' and year =: para1

rec_type = 'Prev' and year =: para1-1
rec_type = 'Prev' and (status = 'c' and date =: para2 or status = 'I' and date)<=>

Display of the results of the query with the column names unknown
I use this code to grab the headers of columns in a select * statement. (I never know what table is queried out of 12 000 or more.) I want to make a loop on the column headers, then the query results in a web page table.

< cfoutput >
< cfset colHeaderNames = ArrayToList (recordset1.getColumnList ()) / >
#colHeaderNames #.
< / cfoutput >

Is there a similar method or suggestions for the release of the results of the query - now that I know the column headings?
If I understand correctly, you can do something like the code below.

results on the query with filter, but no results when the filter removed
I was handed the query below and I may be missing something blinding here but if I run it I get no results

SELECT lipqoh
OF f41021 a, b f0006
WHERE b.mcmcu = a.limcu AND
b.mcstyl = "W";

If I add the filter a.liitm = 105900 as data below is returned (although the inputs are 0 as expected at the moment, this isn't always the case)

SELECT lipqoh
OF f41021 a, b f0006
WHERE b.mcmcu = a.limcu AND
b.mcstyl = 'W '.
a.liitm = 105900;

the fields for each of the tables mentioned in the motion have the following features

lipqoh number NULLABLE
mcmcu Char(12 BYTE) NOT NULLABLE
mcstyl tank (2 BYTE) NULLABLE
liitm number NO NULLABLE

Any guidance would be greatly appreciated
Thank you for providing feedback. The only difference seems to come from the mcstyl columns.
The following snipplet perhaps explain how this expression may be true or not true according to the data types.
```
select * from dual
where 'W ' = cast('W' as char(2 byte));

DUMMY
-----
X

select *  from dual
where cast('W ' as varchar2(2 byte)) =  'W';

no rows found
```
This statement returns all rows?
```
SELECT lipqoh
FROM f41021 a , f0006 b
WHERE b.mcmcu = a.limcu
AND   b.mcstyl = 'W '; /* blank added */
```
I expect so. I still don't understand why oracle treats differently the two queries. However I do not have an adequate control environment. Your version is simply a bit outdated (no longer supported). And I know that some of the type conversion rules had been changed between 9i and 10g.
