• Select values from the db1 table and insert into the DB2 table

  Hello
  
  I have three databases oracle running in three different machines. their ip address is different. among the DB can access databases. (means am able to select values and insert values into tables individually.)
  
  I need to extract data from the DB1 table (ip say DB1 is 10.10.10.10 and the user is DB1user and the table is DB1user_table) and insert the values into DB2 table (say ip DB2 is 11.11.11.11 and the user is DB2user and table DB2user_table) of DB3 that is to have access to the two IPs DB.
  
  How do I do this

  Depending on the amount of data must be moved between DB1 and DB2, and the frequency at which this should happen, you might consider the SQL * COPY more control. I think it's very useful for one-off tasks little, so I can live within its limits of the data type. More http://download.oracle.com/docs/cd/E11882_01/server.112/e10823/apb.htm#i641251.

  Change some parameter of sqlplus session are almost mandatory in order to get decent transfer rates. Tuning ARRAYSIZE and COPYCOMMIT can make a huge difference in flow. LONG change may be necessary, too, depending on your data. The documentation offers these notes on use:

  To activate the copy of data between Oracle and databases non-Oracle, NUMBER of columns is replaced by DECIMAL columns in the destination table. Therefore, if you are copying between Oracle databases, a NUMBER column with no precision will become a DECIMAL column (38). When copying between Oracle databases, you must use SQL commands (CREATE TABLE AS and INSERTION), or you must make sure that your columns have a specified precision.

  SQL * the VALUE LONGER variable limits the length of the LONG column you are copying. If all LONG columns contain data exceeds the value of LONG, COPY truncates the data.

  SQL * Plus performs a validation at the end of each successful COPY. If you set the SQL * variable more COPYCOMMIT DEFINED to a value positive n, SQL * Plus performs a validation after copying all lots n of records. The SQL * Plus ARRAYSIZE variable SET determines the size of a batch.

  Some operating environments require that the service names be placed between double quotes.

  From a SQL * Plus term on DB3, can resemble the command to move all content from my_table in DB1 to the same table in DB2

  COPY from user1/pass1@DB1 to user2/pass2@DB2 -
  INSERT INTO my_table -
  USING select * from my_table
  

  Note the SQL code * more line-continuation character ' - '. It is used to escape the newline character in a SQL * Plus command if you do not have to type all on one line. I use it all the time with this command, but I can't locate the documentation on that right now. Maybe someone else can put their finger on it.

  There are other ways to accomplish what the command copy and it is not without its quirks and limitations, but I find that there is usefulness in an Oracle Toolbox.

• Export data from the database Table in the CSV file with OWB mapping

  Hello
  
  is it possible to export data from a database table in a CSV with an owb mapping. I think that it should be possible, but I didn't yet. Then someone can give me some tips how to handle this? Someone has a good article on the internet or a book where such a problem is described.
  
  Thank you
  
  Greetings Daniel

  Hi Daniel,.

  But how do I set the variable data file names in the mapping?

• How to get the string (specified by row and column) of txt file with labview

  Hello world

  How to get the string (specified by row and column) of txt file with labview

  THX

  As far as I know, a text file has no column.  Be more specific.  Do you mean something like the 5th word on line 4, where the words are separated by a space, and lines are separated by a newline character?  You can read from the spreadsheet String function and set the delimiter to a space.  This will produce a 2D channels table.  Then use the table to index and give the line number and column number.

• How to create views of data from different databases tables in2

  Using Oracle 10.2 g
  
  I have 2 databases Gus and the haggis on schema Comqdhb.
  
  Glink indicates a link of database between Haggis and Gus
  
  In Gus, there is school that contains columns with same name upn, grade, subject, student of tables...
  
  STUDENT

  Create views in your database HAGGIS who join their all the qualities of the review. You should have a point of view that will produce the following relationship:
  examGrade (upn, subject, examlevel, sn, rank, academicYear)
  
  So I need to create a view that gets the data from the tables in the databases.
  
  create view as examGrade (upn, subject, examlevel, sn, rank, academicYear) like some s.upn
  
  
  But I don't get the selection of a column of 2 tables in different databases

  Help me, thank you.

  The issue is that I can't understand that I should create the view by the union of the haggis and the two gus data or only haggis.
  the reason I believe I need to combine the two is mentioned * "" create views in your database schema HAGGIS who join their all the qualities of the review. ". *
  By the mention of creating views and who join their all the qualities of the review, it probably means to obtain the data of the GUS and HAGGIS.

  This is my interpretation of the assignment, too.
  If you ask just the tables on Gus, you will get the ranks of three of the four schools: it's not all examination classes.
  If you ask just the tables on Haggis, you will get the ranks of any of the four schools: it's not all examination classes.

  2nd prob is that if have decided to create a view that gets the data from these two gus and therer haggis would be a lot of duplication involved due to the cross product

  Why would there be "repetition involved due to the cross-product"?
  If the quuery of Gus produces 100 lines, the request of product Haggis 30 rows, then the UNION of the two will have 100 + 30 = 130 lines (assuming, as you say, each student is at school only one).

  the query I wrote is

  Create view examGrade (upn, subject, examlevel, sn, rank, academicYear)
  as
  Select distinct s.upn as upn, g.subject as topic,
  g."LEVEL" as examlevel, g.grade as rank, to_number (g.academicyear) as academicyear
  of s comqdhb.student, comqdhb.grade g
  s.UPN, sb.subject, g.elevel, g.grade, s.acyr select Union
  of comqdhb.subject@glink sb,comqdhb.student@glink s,comqdhb.gradevalues@glink g;

  You should not write, not to mention not formatted zip code. I have a little time I can devote to answering questions in the forum. Do you want me
  b spend this time formatting your code, so I can understand the question, and no time to answer, or
  b spend only a little time reading understanding your code and spend most of my time to help you?
  I would prefer (b), but the choice is yours.
  See the statement that I posted in my last post for an example of the formatted code. You see how it appears in a box with a police fixed-width, and multiple spaces are printed? This is because I typed {code} (all small letters), before and after the section I wanted formatted.

  At least put each table in the FROM clause on a separate line, so it is easy to know if you have enough join conditions.
  If you have N tables in the FROM clause, you almost always have at least N-1 join conditions that specify how the tables are linked together. For example, if talk you about two tables, quality and student, you expect to see a join condition that tells you when you have data in a table, how to find related data in the other table, such as

  g_gus.upn = s_gus.upn
  

  No no no join conditions will cause "repetition involved due to the cross product.

  Sorry, if there is data as long as you can't post here, there is much too much for me to read.
  Make a sample set, containing a few (maybe five) students and a few shades of each student. It is fine to copy a few lines of your actual data.

  That's all the time I have for today. I can't wait to get the data and formatted requests.

• How to get data from one or several times of perticuler dates

  (1) how can we get data from one or more dates perticuler.
  for example. date of 01/01/2011 and time is 00:00:00 to 23:59:59
  
  and
  
  (2) how can we get data from one or more dates perticuler.
  from date 01/01/2011 to 01/02/2011 date and time e.g. is from 00:00:00 to 23:59:59.
  
  can we?

  Hello

  Use a WHERE clause to include only certain lines.
  For example:

  SELECT     *
  FROM     table_x
  WHERE     dt     BETWEEN TO_DATE ( '01/01/2011 00:00:00'
                      , 'DD/MM/YYYY HH24:MI:SS'
                      )
            AND     TO_DATE ( '01/01/2011 23:59:59'
                      , 'DD/MM/YYYY HH24:MI:SS'
                      )
  ;
  

  In this example, the first date (before the keyword AND) and second (after the keyword AND) lie on the same calendar day. It's just a coincidence, they can be on different dates.
  The first date must not be later than the date of the second; If this is the case, you will get 0 found lines.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

  I'm confused by your reference to "profiles"? What do you mean by profile? If you're referring to something called host profiles this function treats remaining with configurations between hosts in a cluster that is compatible with the addition of new hosts in a given cluster. This feature won't be available before vSphere 4.0 and has Nothing to do with performance information.

  Please re-read my last comment, if you are looking to retrieve performance data, you must either connect to vCenter or connect to each of the individual hosts to collect this information. I hope it's clear.

• How to get data from an Excel file exist using report generation tools

  I try to use the Excel vi get the data of the report generation tool, but I can't understand how to activate a path can be explored in the right type for the VI.  I tried to use the new Report.vi, but this does not work unless you use a template.  It will not open an existing excel file and make an open report to extract data from.

  Essentially, I have a bunch of excel files that have data in them, and I want a VI allows to analyze the data.  I'm going to pull in all the data directly from the excel file so I don't have to reproscess them all in text so I can use the more standard datasheet live but to convert even the excel file programtically in labview I still need to be able to open the excel file and get the data?

  I found my problem.  It turns out that only not to have had a problem with the tool box new report vi.  I had accidentally wired an input control of path of folder instead of an input control of path of file to it.  Changing the file type took care of her and I was able to access excel files, I tried using the new report VI to extract the file, and Excel Get Data to extract the data.

• How to get data from vROps?

  Hello

  In older versions, we could get out vROps via an adapter of repository data. But with vROps 6.0, I couldn't find that everything about repository adapter and the other as the HTTP Post adapter. I've seen a few posts on CaSa API and SDK, but there is no documentation on this topic. What can I use to get data on how do I configure it? I'll be happy if I can help.

  Kind regards

  Hi Ramazan

  The API of CaSA is Cluster and Administration of the Group and is located at https://vrops-url/casa

  I have not found any documentation for it.

  What you need is https://vrops-urlsuite - api

  It is a small site with sample code and complete documentation. You can even call the API directly from your browser!

  Start with this, for example: https://vrops-url/suite-api/api/resources? name =something

• How to compare data from the two table column by column and connect the result compared to the separate table

  Hello experts...

  I'm new to this forum and Oracle coding complex.

  I have a task in which I want to compare two tables with the same structure, same columns. My Oracle database is 11g Release 2. I want this column-by-column comparison and save the result in a separate table. (say result_table)

  The structure of the table would be as follows:

  SQL > desc emp;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  SQL > emp_comp desc;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  Both of the tables EMPNO is the primary key.

  I want to compare these two tables based on the EMPNO (EMPNO even is both tables).

  The result log table would be as follows:

  SQL > create table result_table

  2 (check_sr_no, number (5),)

  table_name 3 varchar2 (30),

  ROW_ID 4 varchar2 (20).

  column_name 5 varchar2 (20).

  6 column_data varchar2 (1000).

  compared_by 7 varchar2 (10));

  Table created.

  SQL > alter table result_table

  2 Add the constraint result_table_pk

  3 primary key (check_sr_no);

  Modified table.

  The name of the table and the name of the column will not be hardcoded (based parameter by user)

  I tried to use the dbms_comparison package, but do not find comparison of column to column.

  I also used by using the query operator LESS. It's showing the difference in rank.

  I also went to https://asktom.oracle.com/pls/apex/f?p=100:11:0:P11_QUESTION_ID:2151582681236

  Your help will be very appreciated.
