Script Insert statement to extract data from Table in Oracle 7i
Hi all, I have an old Oracle legacy system that works for more than 15 years. Every now and then, we need to extract data from this table @ ORacle 7i to import to Oracle 10 G.My thoughts are to create a script to Insert statements in oracle 7 and that, to be deployed to Oracle 10 G.
I found cela scripts in Google and don't know exactly how it works. No explanation on these scripts, would be greatly appreciated. I find that this format can help to produce a set of insert statements in this table to the last table to 10G.
< pre >
-Step 1: create this procedure:
create or replace function ExtractData (v_table_name varchar2) return varchar2 as
Boolean b_found: = false;
v_tempa varchar2 (8000);
v_tempb varchar2 (8000);
v_tempc VARCHAR2 (255);
Start
for tab_rec in (select table_name from user_tables where table_name = upper (v_table_name))
loop
b_found: = true;
v_tempa: =' select ' insert into ' | tab_rec.table_name |' (';
for col_rec in (select * from user_tab_columns)
where
table_name = tab_rec.table_name
order by
column_id)
loop
If col_rec.column_id = 1 then
v_tempa: = v_tempa | " ' || Chr (10) | " ' ;
on the other
v_tempa: = v_tempa |', ". Chr (10) | " ' ;
v_tempb: = v_tempb |', ". Chr (10) | " ' ;
end if;
v_tempa: = v_tempa | col_rec.column_name;
If instr(col_rec.data_type,'CHAR') > 0 then
v_tempc: = "' |' | col_rec.column_name |'| " ' ;
elsif instr (col_rec.data_type, 'DATE') > 0 then
v_tempc: = "' to_date ("'| to_char('|| col_rec.column_name||',''mm/DD/YYYY HH24 '') | ") (', "' dd/mm/yyyy hh24"') "';
on the other
v_tempc: = col_rec.column_name;
end if;
v_tempb: = v_tempb | " ' || Decode('|| col_rec.column_name||',''Null'','||v_tempc||') | " ' ;
end loop;
v_tempa: = v_tempa |') values ('| v_tempb |'); "from ' |" tab_rec.table_name | « ; » ;
end loop;
If not b_found then
v_tempa: ='-Table ' | v_table_name | 'not found ';
on the other
v_tempa: = v_tempa | Chr (10) | "select"-commit; "double;';
end if;
Return v_tempa;
end;

Hello
Well what this script do.
You will pass a table name as input to the function that will return varchar2 (string - insert statement). It will generate 2 t1.sql of sql script that contains the output sequence.
Will use the first passed the user_tables scipt to check if the input table name exists and if there is the will reterive user_table_columns column names and generate the following sql script.
Now, this t1.sql will run to generate a final sript formally orders insert that will run you on the target schema (make sure that the table exists).
* #t1.sql*
set echo off
spool recreatedata.sql
select '-- This data was extracted on '||to_char(sysdate,'mm/dd/yyyy hh24:mi') from dual;
select 'insert into MY_OBJECT1 ('||chr(10)||'OWNER,'||chr(10)||'TOTAL) values ('||decode(OWNER,Null,'Null',''''||OWNER||'''')||','||chr(10)||''||decode(TOTAL,Null,'Null',TOTAL)||');' from MY_OBJECT1;
select '-- commit;' from dual;
spool off
Then @t1.sql runs, and the general insert for the infeed table table.
-- This data was extracted on 03/09/2009 23:39
INSERT INTO MY_OBJECT1 (OWNER, TOTAL)
VALUES ('MDSYS', 92800);
INSERT INTO MY_OBJECT1 (OWNER, TOTAL)

Extracting data from table without refreshment and without using the tab key.
Hi friends,
I have a problem I want to extract data from table without discount in the text field without using the Tab key. When I enter a field value any value then the text corressponding should enter into corressponding textfield without using the Tab key.
for example. When I get back emp_id 101 in a text field then first_name and last_name, address would come in to the text fields corressponding without refresh and use the Tab key.
How can I do that.
Thank you
MauryHi Maury,
I guess it's similar to: retrieving data without refreshing rather than Re: value of a textfield should enter into an another textfield without using the TAB ?
If so, the only change you want to bring on the first is to use the parameter "Onkeyup" instead of "onchange" in the 'HTML Form attributes of the element' element.
Note, however, that the user must move away from the issue at some point (for example, to click on a button), so the onchange will fire anyway.

Extracting data from table.
Hello and happy Friday.
I'm reworking an instrument for an HP 662 X power driver. We have four in the lab and I want to have a panel that writes the channel information and reads what the instrument setting are. I have entries works fine, but I can't extract the data from the VI "read the voltage and current. What I would like is the opposite of "build the Subvi where I can get a table and the elements come they channel to the next available line. I have attached the control program which should give you a better understanding of what I'm trying to accomplish here. Any ideas will be greatly appreciated. The pilot, with that I started is one downloaded from NEITHER!

Now, here I want to extract the data with condition as
PRODUCTIONDATE > = the current week Monday
so I would skip only two first rows and will need to get all the lines.
I tried to use it under condition, but it would not give the data for the values of 2013.
TO_NUMBER (to_char (to_date (PRODUCTIONDATE, 'yyyymmdd'), 'IW')) > = to_number (to_char (sysdate, 'IW'))
Any help would be appreciated.
Thank you

by the way: it is generally a good idea to store date values in date columns.One of the many reasons why store date information in VARCHAR2 columns (especially VARCHAR2 (200)) is a bad idea, it's that the data invalid get there, causing errors. Avoid the conversion of columns like that at times, if possible:
SELECT * FROM production WHERE productiondate >= TO_CHAR ( TRUNC (SYSDATE, 'IW') , 'YYYYMMDD' ) ;

Hello
You should start using the authority, either zendamf which is used by the data wizards in flashbuilder 4 or with amfphp which is probably better than zend but has not all nicities such as the creation of objects of value.
This project uses amfphp, basically, it uses remoteobjects so returned php is in a ready to put directly into a grid or a datagroup arraycollection collection.

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.
Adapt to the exit of styles and different types of data are needed.

How to ETL extract data from database Oracle 11.1 using Cognos Data Manager 10.1
Hello
I need to run the IBM Cognos Data Manager 10.1 version ETL tool for extracting data from the Oracle11.1 database.
My understanding is that, from the point of view of database, the best way would to have a stored procedure that will provide a reference cursor in the ETL client tool.
However, a database procedure the ETL tool running seems not to be possible in this version of the data manager.
If someone has done this before? What is the best way for this snippet to do?
Thank you
Emilija
Annabelle says:
My reading of original question: "What is the best way for this snippet to do?"
Sorry - is NOT helping.
The BEST way to extract data from a table is to use a SELECT statement.
You said you want to do.
So just repeat your original question instead of those that ask you to answer will not move forward us.

extract data from XMLType using vbscript on OleDB?
Hello.
We have a problem where the XMLType column data to get in 11.2.0.1 on Windows x 64 worked very well, but we have moved to 11.2.0.3 Patch 21 and the column type changed to binary storage default, and we started to do read errors when the data was greater than 32 k (or so it seems).
I opened a SR, and Oracle support sent me a VB script to test playback of the table on OleDB. However, their script doesn't seem to work as announced, so after a lot of gooling, came to us with the following to read a column of xmltype - not the same table, just to test that the vbscript works:

This works perfectly and displays 12 rows in this column in a vbscript dialog box, but I am not able to do to extract the XMLType column clob data. I try with for example. RS. Open 'select REPLYDATA.getclobval () from SW_REPLY', stupid but just get errors.
Is it possible to extract data from XMLType on OleDB with vbscript? It cannot be OleDB itself which poses problem, because it has worked in our application and 11.2.0.1 although with < 32 k of data. But it would be nice to have a working test case while we were able to test out our app. If it is with vbscript or c# is irrelevant.
ignore the message, it is possible. Support of Oracle gave me this:
the con value = createobject ("adodb.connection")
con. Open "provider = oraoledb.oracle; user id = finite9; password = password1; data source = DEVTST ".
Set rs = createobject ("adodb.recordset")
RS. Open "select t.REPLYDATA.getclobval () as xmltestdata OF SW_REPLY t", con
While not on the place. EXPRESSIONS OF FOLKLORE

Set rs = nothing
con. Close

but there is a problem when xmldata exceeds a certain size. small starters work well if.

Any help would be much appreciated. Extract data from an xml file takes almost an hour to 2.5 M. data is there a solution to this.

Thank you
MhandOK, in this case the best option is to store the answer in a binary table of XMLType (may be a temporary table if you want to) and run the query from there:
CREATE TABLE tmp_xml OF XMLType XMLType STORE AS SECUREFILE BINARY XML -- default storage in your version ;
INSERT INTO tmp_xml VALUES(XMLType(response));
SELECT b.entity_id, c.instance_id, d.attribute_id, d.data_type, d.attribute_value, d.outcome_style FROM tmp_xml t, XMLTABLE( XMLNamespaces('http://schemas.xmlsoap.org/soap/envelope/' AS "SOAP-ENV" , 'http://oracle.com/determinations/server/10.3/rulebase/assess/types' AS "typ") , 'SOAP-ENV:Envelope/SOAP-ENV:Body/typ:assess-response/typ:global-instance/typ:entity' PASSING t.object_value COLUMNS ...

Query to extract data from source DB driver using process mapping pre...
Hi all
I have a source for the query to retrieve the data from the source database. Looking for suggestion what could be the best approach to extract data from the source database.using owb 11 GR 1 material.
I'm in printing, create the process of mapping driver prerequisite for aid to perform immediate with Create table T1 as a sql query. Petition to the sides of the Insert into T1 Select * from Source_Table in the different database.
Certainly, need to create Db users in the Source database, to get privileges to read the data of source_database.
Is - this good aproach to or of any other alternative to achieve this.
Means, create the table in the transit area (desired area, where I am) and using driver mapping process before you run the select query to retrieve data from a data source.
Would apreciate your previous answer.
Thank you

Hello
Here, I want to extract data from the XY graph. I joined vi which I use for table 1 d. How can I use this for 2D table VI.
Thank you
Hi Alex,
You can use the same approach.
The only thing that changes is the function ArraySubset in its adaptation to the 2D matrix. You can select rows or clumns of your data (depending on how you have generated them)...

Extract data from error HFM, float to Numeric?
Hi all
We extract data from HFM,.
HFM-> SQL-> FILE staging
Our mapping, flow, everything seems fine. When we run this out on the third market errors while extracting data with the following:
com.hyperion.odi.common.ODIHAppException: arithmetic overflow error conversion float type numeric data.
We researched and found to increase the logical length should solve this problem.
Our Source has a length of 16...
We have increased the logical length of target from 16 to 30, and he rest-error. We even tried 50, 100 for the logical length.
We are at Version 10.1.3.6.0.
Any suggestions on how to fix this?
Thank you!
Published by: user10678366 on May 22, 2013 13:28Have you tried changing the scale of all the columns float, right?
It can be a ridiculously large number coming from HFM. So, go to store for your data source in ODI and manually change the data type of column type VARCHAR of size like 100 or more. That would force the ODI to create the staging table with columns of characters for the field. Data will be retrieved anyway. Given that you write it in file, type of character should not matter. In addition, if writing to the file fails for any reason, you can do a max on the staging table and find the value problem in the table (while in HFM, you may not be able to do).

How to extract data from SQL server in the FDM
Hi Experts
How to extract data from a SQL server HFM to another SQL Server using scripts for integration in FDQM?
concerning
DevCould you clarify why you want to do this?
If you try to synchronize two databases (apps) to have a backup or something running in a development environment, I suggest configuring replication between two databases. It would be much more effective to do it at the SQL Server level through the application of FDM, IMHO.
