Extract data from the table on hourly basis

Hello

I have a table that has two columns date all the hours of the base and the response time. I want to extract data from the date corresponding previous hourly basis with the response time. The data will be loaded into the table every midnight.

for example: today date 23/10/2012
I want to extract data from 22/10/12 00 to the 22/10/12 23

The sub query pulls the date as demanded, but I'm not able to take the time to answer.

with one also
(select min (trunc (lhour)) as mindate, max (trunc (lhour)) as AVG_HR maxdate)
SELECT to_char (maxdate + (level/25), "dd/mm/yyyy hh24") as a LEVEL CONNECTION dates < = * (1) 24;

Please help me on this.

Try this

SELECT * FROM table_nm
 WHERE to_char(hour,'DD') = to_char(SYSDATE-1,'DD')

The procedure allows for the header and the data to separate files if necessary. Just by specifying the file name "header" will put the header and the data in a single file.

extract data from the generic cursor xy graph

Hi, I'm new in this Forum.

In my VI I need to extract the data from the graph xy of one cursor to another, how can I do this?

I want to extract all the data between the two sliders, to develop.

Thank you

In addition to everything said altenbach, you want the slider list: property of the Index. That will tell you where in the table of data, the sliders are.

The attached VI shows how we can work and also meaningless how it can be with common types of XY data.

Select * example;

create table hasil1 (c1 varchar2 (500), c2 varchar2 (500), c3 varchar2 (500));

-This step I create the procedure to insert xml data into the table as the batch.

DECLARE
x XmlType;
BEGIN
Select XML_SPEC in x for example;

insert into hasil1
SELECT
p.Extract('/Record/Field/@externalReference').getstringval (C1),
p.Extract('/Record/Field/@participantID').getstringval (C2),
p.Extract('/Record/Field/@participantName').getstringval () as c3
TABLE (XMLSequence (Extract(x,'Message/List/Record'))) p;
commit;
END;
/

-when the result of select hasil1, the output is back 3 rows and 3 columns, but all data is a null *.

Best regards
Sigcle
You don't explain what output you need, but I guess something like this:
```
SQL> insert into hasil1 (c1, c2, c3)
  2  select x.c1, x.c2, x.c3
  3  from example t
  4     , xmltable(
  5         'Message/List/Record'
  6         passing t.xml_spec
  7         columns c1 varchar2(500) path 'Field[@name="externalReference"]'
  8               , c2 varchar2(500) path 'Field[@name="participantID"]'
  9               , c3 varchar2(500) path 'Field[@name="participantName"]'
 10       ) x
 11  ;

3 rows inserted

SQL> select * from hasil1;

export data from the table in xml files

Hello

This thread to get your opinion on how export data tables in a file xml containing the data and another (xsd) that contains a structure of the table.
For example, I have a datamart with 3 dimensions and a fact table. The idea is to have an xml file with data from the fact table, a file xsd with the structure of the fact table, an xml file that contains the data of the 3 dimensions and an xsd file that contains the definition of all the 3 dimensions. So a xml file fact table, a single file xml combining all of the dimension, the fact table in the file a xsd and an xsd file combining all of the dimension.

I never have an idea on how to do it, but I would like to have for your advise on how you would.

Thank you in advance.

You are more or less in the same situation as me, I guess, about the "ORA-01426 digital infinity. I tried to export through UTL_FILE, content of the relational table with 998 columns. You get very quickly in this case in these ORA-errors, even if you work with solutions CLOB, while trying to concatinate the column into a CSV string data. Oracle has the nasty habbit in some of its packages / code to "assume" intelligent solutions and converts data types implicitly temporarily while trying to concatinate these data in the column to 1 string.

The second part in the Kingdom of PL/SQL, it is he's trying to put everything in a buffer, which has a maximum of 65 k or 32 k, so break things up. In the end I just solved it via see all as a BLOB and writing to file as such. I'm guessing that the ORA-error is related to these problems of conversion/datatype buffer / implicit in the official packages of Oracle DBMS.

Fun here is that this table 998 column came from XML source (aka "how SOA can make things very complicated and non-performing"). I have now 2 different solutions 'write data to CSV' in my packages, I use this situation to 998 column (but no idea if ever I get this performance, for example, using table collections in this scenario will explode the PGA in this case). The only solution that would work in my case is a better physical design of the environment, but currently I wonder not, engaged, as an architect so do not have a position to impose it.

Export data from the table
Hello. Is it possible to export data from a table in Oracle using SQL Loader? If Yes, can you tell a good examples?
Hello

Hello. Is it possible to export data from a table in Oracle using SQL Loader?

No, with SQL * Loader, you can load data from external files into tables not export.

coil c:\temp\empdata.txt
sqlplus abc.sql (assumes that abc.sql runs select * from emp)
spool off

It cannot work like this, because the declaration of the COIL is not recognized outside the SQL * Plus the term.

But, you can include the statement of the COIL in abc.sql like this:
```
spool c:\temp\empdata.txt
select * from emp;
spool off
```
Then, you just have to run the SQL script as follows:
```
sqlplus  @abc.sql 
```
However, I advise you to use Oracle SQL Developer, this is a free tool and with it you can export a Table in several types of format (html, xml, csv, xls,...).

Please find attached a link to this tool:

http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/Overview/index.html

Hope this helps.

Update on the table by extracting the data from the table even under certain conditions

Hi Experts,
I have the table EMP which currently has 6 entries.
EMP_SYS BATCH_NO JOIN_DATE LOGIN_ID STATUS FLAG
1 FEBRUARY 10 PROD 84 Y IND123 ABC
DEV 1-23 APRIL 98 Y IND123 ABC
2 12 APRIL PROD 98 Y IND123 ABC
2 2 APRIL DEV 98 Y IND123 ABC
3 13 APRIL PROD 98 Y IND123 ABC
3 3 APRIL DEV 98 Y IND123 ABC
CONDITION: I need to take lines which has the minimum BATCH_NO for each of the EMP_SYS
for example,.
1 FEBRUARY 10 PROD 84 Y IND123 ABC
DEV 1-23 APRIL 98 Y IND123 ABC
For the above two lines, I need to update the status of DEF. How to select this criterion and update in the same query?
Currently, I used the query to select the minimum BATCH_NO for each of the EMP_SYS below.
SELECT EMP_SYS, BATCH_NO, JOIN_DATE, FLAG, LOGIN_ID, STATUS
Of
(
EMP_SYS, BATCH_NO, JOIN_DATE, FLAG, LOGIN_ID, STATUS, SELECT ROW_NUMBER)
COURSE NR (PARTITION BY ORDER OF EMP_SYS OF EMP_SYS)
FROM EMP
WHEN STATUS = 'ABC' AND FLAG = "Y".
)
WHERE
NR = 1;
If I try to use the update on the above query statement... It updates every 6 rows instead of 2 rows.
Please suggest me a way to update only the two lines that has the minimum BATCH_NO for each of the EMP_SYS.

But is possible to write the query without using the Group of?

Update e EMP

set STATUS = "DEF".

where BATCH_NO = (select min (BATCH_NO) from EMP I where STATUS = 'ABC' AND FLAG = 'Y' and i.emp_sys = e.emp_sys)

extracting data from the CLOB using materialized views

Hello
We have xml data from clob which I have a requirement to extract (~ 50 attributes) on a daily basis, so we decided to use materialized views with refreshes full (open good suggestions)

- cannot change the source as its defined provider table
- cannot do an ETL
DB is 11g R2
Any ideas/suggestions are very much appreciated

I explored a similar approach, using the following test case.

It creates a table "MASTER_TABLE" containing 20,000 lines and a CLOB containing an XML fragment like this:

09HOLVUF3T6VX5QUN8UBV9BRW3FHRB9JFO4TSV79R6J87QWVGN

9FJ1JZ615EOUIX6EKBIVOWFDYCPQZM2HBQQ8HDP3ABVJ5N1OJA

then an intermediate table "MASTER_TABLE_XML" with the same columns with the exception of the CLOB which turns into XMLType and finally a MVIEW:

SQL > create table master_table like

2. Select level as id

3, cast ('ROW' | to_char (Level) as varchar2 (30)) as the name

4       , (

XMLAGG 6)

7 xmlelement (evalname ('ThisIsElement' | to_char (Level)), dbms_random.string ('X', 50))

8                    )

10                  )

The discount is then performed in two steps:
1. INSERT INTO master_table_xml
2. Refresh the MVIEW
(Note: as we insert in an XMLType column, we need an XML (only root) document this time)

How to extract data from the APEX report with stored procedure?
Hi all

I am doing a report at the APEX. the user selects two dates and click on the GO button - I have a stored procedure linked to this region of outcome for the stored procedure is called.

my stored procedure does the following-

using dates specified (IN) I do question and put data in a table (this painting was created only for this report).

I want to show all the data that I entered in the table on my APEX report the same procedure call. can I use Ref cursor return? How to do this?

Currently, I use another button in the APEX that basically retrieves all the data from table. Basically, the user clicks a button to generate the report and then another button for the report. which is not desirable at all :(

I m using APEX 3.1.2.00.02 and Oracle 10 database.

pls let me know if you need more clarification of the problem. Thanks in advance.

Kind regards

Probashi

APEX to base a report out of a function that returns the sql code... Your current code goes against a Ref cursor returns the values...

See this thread regarding taking a ref cursor and wrapping it in a function to channel out as a 'table' (use a cast to cast tabular function vale)...

(VERY COOL STUFF HERE!)

Series read returns the string with excess-need information to extract data from the middle of the string

I read data from a STI flow meter using the base series writing and reading which used the VISA. The read string begins with 'OK' or an error code, then a carriage return, then the data follows streaming rate temp pressure flow rate comma comma comma comma Temp... and so on. The string ends with a CR LF. I need to pull the flow, temperature and pressure data out of the string and write it to a file. I have difficulties to find a function that will retrieve the data for the string. Any suggestions? Thank you.

Try the subset of string in the palette of the chain.

Or match the model if you want a more direct control.

Also a good way is the string analysis, but you must be willing to read oexactly, what happens or an error, pass the entrance.

This is the table that you created (its name ends with the digit "1"), not that used in the INSERT statement (its name ends with the letter "L").
