• How to display data from the emp table?

  Hi everyone, this is my first post in this portal. I want to display the details of the table emp... for this I use this SQL statement.
  
  Select * from emp where mgr = nvl(:mgr,mgr);
  
  When I give the entry as 7698 it shows the matching records... and also when I don't give any input then it shows all the records except the Archbishop with null values.
  
  (1) I want to display all the records when I do not give any input, including null values
  (2) I want to display all the records that a Bishop is null
  
  Is it possible to integrate in order to include all these in a single query.

  (2) I want to display all the records that a Bishop is null

  Is it possible to integrate in order to include all these in a single query.

  It's a little unsure what you're asking.
  The following query always includes the lines where mgr is NULL and when the binding variable: mgr is NULL, it displays all the lines:

  SELECT  *
  FROM     emp
  WHERE     LNNVL (mgr != :mgr)
  ;
  

  In other words, when: 7698 = mgr, it displays 6 rows and when: mgr is NULL, it displays 14 rows (assuming you are using the table provided by Oracle scott.emp).

  The following query includes lines where Bishop is ZERO only when the binding variable: mgr is NULL, in which case it shows all lines:

  SELECT     *
  FROM     emp
  WHERE     :mgr     = mgr
  OR       :mgr       IS NULL
  ;
  

  When: mgr = 7698, this will display 5 rows and when: mgr is NULL, it displays 14 rows.

  The following query includes lines where Bishop is ZERO only when the link variab; e: mgr is NULL, in which case it shows only those rows where mgr is NULL. In other words, it treats NULL as a value:

  SELECT     *
  FROM     emp
  WHERE     DECODE ( mgr
              , :mgr, 'OK'
              )     = 'OK'
  ;
  

  When: mgr = 7698, this will display 5 rows and when: mgr is NULL, it displays 1 row.

  Don't know why you need it on a single line, but you could:

  Select XMLTYPE (REGEXP_REPLACE (XMLROOT (XMLELEMENT (staticdata, XMLELEMENT (EMP, XMLELEMENT(ID,ID), XMLELEMENT(NAME,NAME))), version "1.0" encoding = "UTF - 8'), CHR (10) |)) ' *<><'))>

• 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
  
  Edited by: Aemunathan on February 10, 2010 23:12

  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.

  The basic concept is easy - set the parent entity, set the child entity, join the parent to the child.

  If some entities will not have parents (root entities), then an outer join is required of the child entity to the parent entity.

  Everything simply because the two entities are in the same table, does not change the logic or the approach. It's perfectly valid for a join table.

• Remove the entry from the ARP table

  I need to create a program to remove an entry in the ARP table in Windows 7 with LabVIEW and TestStand.  The test that I develop contacts ESA via Ethernet.  Each HAD has the same IP address at the beginning but different MAC addresses.  I note that there may be long delays in test is running when you try to connect and remove the previous entry in the ARP table seems to help.  But now I have to do it manually through the command line.  The command 'arp d' requires elevated privileges.  I had a hard time getting LabVIEW to raise the system exec.  Does anyone have an ideas? Is there a .NET access to the ARP table?

  Thank you

  Paul

  I'll try to look into ARP sync settings setting in Windows.

  We have suffered from various problems of connection-performance TCP a few years ago and our solution was to change the default number of TCP sockets and delays (we knew port exhaustion). The tweeks eliminated most of our problems, no changes to code LV/TS not required.

  I tried to find info on ARP parameters for Windows 7, but it seems that there is much less info available that ther is for XP.

  Key words of the most common registry for older versions of Windows have been 'ArpCacheLife' and 'ArpCacheMinReferencedLife.

  EDIT:

  These parameters were apparently kidnapped in Vista. I found this on the site of $ M; they can apply to later versions, as well as M$ is a request for change to the management of the ARP...

• Using data from the control table

  Hello

  I would like to use the data entered in a table to automate volume/sequence of airflow for a test Chamber. As shown in the screenshot of control table, the first column indicates the number of iterations by elements of array in a series of tests and the second data column specifies the length of each line sequence. Entries in the other columns are specific to different valves and specify values set required in the flow meter.

  

  I guess my question is how can I index/assign each column of the table such that the data to exploit the respective valves are obtained in subsequent iterations all acquire simultaneously with data from other components in the order? While I recognize that the solution may be very simple, I searched on through various examples and messages on the tables and the tables without knocking on a solution. The attached .vi allows me to be a part of the series of tests.

  Best regards

  Callisto

  Hi Callisto,

  If I understand your question then the solution is actually quite simple. The important point to keep in min is the fact that the Table control can actually be treated as an array of string. You can then use all the traditional table manipulation tools and techniques to manipulate your data as you wish. For example, use the Array Index function to retrieve specific columns and then if you want to spend the individual elements in a column in a loop, wire the table until the loop and ensure that indexing is enabled. If you then want to use these data elements to control your test application, you can convert a portion of the resulting string in more useful to digital.

  All these concepts are illustrated in the attached VI. I hope this helps, but let me know if you have any other questions.

  Best regards

  values (62, 'MAINT', 80, 7, 10.3, 15.00);
  

  How can display the records with numbers of different costs for the same unique key (fieldA, fieldB and FieldC)?

  With the help of Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0.

  I hope that my message is clear.

  Thank you!

  Me too.  Always show the complete, accurate, results you want from the data provided.  If you want 2 rows at the exit point, don't tell you want 1.

  Here are the results you want?

  MY_ID FIELDA, FIELDB, FIELDC OLD_COST_A COST_A OLD_COST_B COST_B

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

  MAINT 62 60 5 10.3 10.3 15 5

  MAINT 62 80 7 30.3 10.3 35 15

  If so, here's a way to get them:

  WITH got_old_costs AS

  (

  SELECT fielda, fieldb, fieldc, cost_a, my_id, cost_b

  , LAG (cost_a) OVER (PARTITION BY fielda, fieldb, fieldc)

  ORDER BY my_id

  ) AS old_cost_a

  , LAG (cost_b) OVER (PARTITION BY fielda, fieldb, fieldc)

  ORDER BY my_id

  ) AS old_cost_b

  OF mytest

  WHERE my_id IN (2, 62)

  )

  SELECT my_id, fielda, fieldb, fieldc

  old_cost_a, cost_a

  old_cost_b, cost_b

  OF got_old_costs

  WHERE my_id = 62

  AND (cost_a <> old_cost_a)

  OR cost_b <> old_cost_b

  )

  ORDER BY fielda, fieldb, fieldc

  ;

• missing parenthesis in insertion into separate lines select the table from the other table

  Hello

  could you help me with the following question?

  I have the following tables

  CREATE TABLE table1)

  ID varchar (12),

  col2 varchar (10),

  COL3 varchar (10),

  level varchar (10))

  CREATE TABLE table2)

  Id2 varchar (12)

  A varchar (10),

  B number (1)

  CONSTRAINT PRIMARY KEY PK (ID2, is));

  INSERT INTO table2 (ID2, A, B) SELECT ID, col2

  MAX (CASE WHEN level = "level 1" then 1

  level = 'level 2' then 2

  Level = 3 then 'niveau3') as colIN3)

  FROM table1 GROUP BY ID2, a.;

  the first table have duplicates as follows:

  Id2 COL2 COL3 level

  A1 pepe football level1

  A1 pepe football level2

  A1 pepe football level1

  A1 pepe basket level2

  A1 pepe pingpong level3

  the output should be selected with unique key (ID2, col3) lines and the level must be the greatest.

  Id2 COL2 COL3 level

  A1 pepe football level2

  A1 pepe basket level2

  A1 pepe pingpong level3

  The output of the script tells me the following messages:

  -lack of right parenthesis referring to the max function.

  Thanks adavance.

  Kind regards

  Hello

  Remember the ABC's of the GROUP BY:

  When you use a GROUP BY clause or in an aggregate function, then all in the SELECT clause must be:

  (A) a ggregate function,

  (B) one of the expressions "group By."

  (C) adding to C, or

  (D) something that Depends on the foregoing.  (For example, if you "GROUP BY TRUNC (dt)", you can SELECT "TO_CHAR (TRUNC (dt), 'Mon - DD')").

  To ask him, there are 5 columns in the SELECT clause.  The last one is a function MAX (...); It is an aggregate, is not serious.

  The first 2 columns are also named in the GROUP BY clause, so that they are well.

  The other 2 columns, country and internal_Id do not match any of the above categories.  These 2 columns cause the error.

  There are many ways to avoid this error, each producing different results.  You could

  • remove these 2 columns in the SELECT clause
  • Add these 2 columns in the GROUP BY clause
  • use the aggregation such as MIN, 2-column functions
  • remove the country from the SELECT clause and add internal_id to the GROUP BY clause
  • remove the internal_id from the SELECT clause, and add countries to the GROUP BY clause
  • ...

  What are the results you want?

  Whenever you have a question, please post a small example of data (CREATE TABLE and INSERT statements) for all the tables involved, so people who want to help you can recreate the problem and test their ideas.  Also post the results you want from this data, as well as an explanation of how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).
