• Restore the value of the selected line in the editable Table.

  Hello, I use Jdeveloper 11.1.2.1.0.
  
  My problem is:
  1. Select a line in the editable table.
  2. change the value inside elements of the af:inputText of columns.
  3. tap on restore.
  4. the values of the selected line remains the same.
  
  If I select another line, before the restore, the restore will work as expected.
  
  I want to when you press the button cancel the values of the selected row to be rollback-ed as well.

  Set the immediate on all the inputTextFields in the table and it worked.

• limitation of the same structure add cases

  Hello

  Can I know any excretion have the same structure add event .bcase if I use more than 50 events in strucute even.

  I posted on the forums about the recording of the change in value on multiple controls here and here.

  There is no real problem having lots of event, but it takes a lot of time for each of them create then because I'm lazy, I'm trying to find ways to accelerate my LabVIEW programming - if you have a lot of events that do the same thing, so you can save time by having a single piece of code manage events.

• compare files with the same structure of channel / rename channel(-groups)

  Hello

  I have several groups ch with many channels in the file of each measure.

  Now, I need to display/compare Channels 2 or more files of measures in a chart. (channel 'speed1' to the file 'measurement1' vs 'speed1' to the file 'GCA2' channel)

  So I import 2 files in the browser und have the same structure of string twice. To distinguish between the channels of the two files I want to rename the channels by script and add the file name of the channel-group name.

  Is this a common way to compare measurement data in files with the same channel names and structures?

  In the affirmative. How can I make a script?

  Thank you very much in advance!

  Ski

  Hi Ski-Fahrer,

  each channel has a name of the institution.

  Data.Root.ChannelGroups ("Name" or Index). Channels (Index or "Name"). Name

  You can assign a new name like this:... Name = "NouvNom".

  I don't think it is necessary to rename the channels. If you do not forget the files. If you want to rename something I only rename the ChannelGroups by adding a date or a serial number.

  Kind regards

• Nested set tables in select query "in the clause of" take long time

  create or replace type t_circuitids is table of the varchar2 (100);

  -Under anonymous block continues to run away and never ends

  DECLARE
  v_circuitid t_circuitids;
  number of v_count;
  l_circuitids VARCHAR2 (4000)
  : = "Value1, value2, value3, value4, Value5";
  BEGIN
  -Query below converts the output concatinated with commas to the list and stores it in the nested table collection v_circuitids
  WITH an ACE

  THE DOUBLE)

  SELECT COUNT (1)
  IN v_count
  TABLE
  WHERE name IN (SELECT COLUMN_VALUE
  TABLE (v_circuitid));
  END;
  /

  -I had the question, query "SELECT COLUMN_VALUE FROM TABLE (v_circuitid)" that is used in code above is responsible for this.

  -Same code works fine in development and Test environments, but prod it continues to work on

  -I solved this problem by creating a temporary table, loading of all values in the collection in the temporary table and using this temporary table "in the clause" "

  -Can answer why his behavior like this when I use the collection where clause?

  -I use Oracle 9i

  Here is a summary of the question and the solution for this.

  -Nested type to collect multiple values

  CREATE or REPLACE the TYPE t_circuitid IS TABLE OF VARCHAR2 (100);

  Below the code will simply on the run.

  DECLARE
  v_circuitid t_circuitid;
  v_count NUMBER;
  BEGIN
  SELECT nal_name
  LOOSE COLLECTION v_circuitid
  OF fs_head
  WHERE groupid = 10;

  SELECT COUNT (1)
  IN v_count
  OF fs_attrib
  WHERE NAME IN (SELECT COLUMN_VALUE
  TABLE (v_circuitid));

  Dbms_output.put_line (v_count);
  END;
  /

  Cause:-SELECT COLUMN_VALUE TABLE (v_circuitid)); -This request is causing problem

  Why?  : - Because the CBO does not know how many lines is present in the collection, by default it takes 8168 lines

  Note:-always happens, it depends on the volume of data in the table, the path chosen by CBO. In my case, the table is huge on prod compared to DEV so he was causing a problem.

  -The following modified code works very well

  DECLARE
  v_circuitid t_circuitid;
  v_count NUMBER;
  BEGIN
  SELECT nal_name
  LOOSE COLLECTION v_circuitid
  OF fs_head
  WHERE groupid = 10;

  SELECT COUNT (1)
  IN v_count
  OF fs_attrib
  WHERE NAME IN (SELECT / * + cardinality (20 t) * /)
  COLUMN_VALUE
  TABLE (v_circuitid) t);

  Dbms_output.put_line (v_count);
  END;
  /

  Solution:-used as cardinality hint below.

  SELECT / * + cardinality (20 t) * / t COLUMN_VALUE TABLE (v_circuitid);

  Using cadinality I am saying CBO which dataset contains 20 lines or less.

  If it is version of Oracle 10 g and more, we can use below code (CARD utility).

  SELECT COLUMN_VALUE TABLE (CARD ((v_circuitid))

• How to store results of the select query in the tables.

  I created a variable varray type and now want to assign some data of output of the select query in pl/SQL, as well as in reports 6i.

  You are in the wrong forum (this is for problems with the SQL Developer tool). You were the one where you have published first on the right, but not to reuse independent threads as you did.

• Query on the organized Table (IOT) Index sorts unnecessarily data

  I created hist3 to the table as follows:
  
  create table hist3)
  reference date,
  palette varchar2 (6).
  Artikel varchar2 (10),
  Menge number (10),
  status varchar2 (4).
  VARCHAR2 (20) text.
  VARCHAR2 (40) data.
  primary key constraint hist3_pk (reference, palette, artikel)
  )
  index of the Organization;
  
  The table being an IOT, I expect that the retrieval of rows in the same order as in the primary key must be very fast.
  
  This is true for the following query:
  
  SQL > select * from hist3 by reference;
  
  -----------------------------------------------------------------------------
  | ID | Operation | Name | Lines | Bytes | Cost (% CPU). Time |
  -----------------------------------------------------------------------------
  | 0 | SELECT STATEMENT | 1000K | 82 M | 3432 (1) | 00:00:42 |
  | 1. INDEX SCAN FULL | HIST3_PK | 1000K | 82 M | 3432 (1) | 00:00:42 |
  -----------------------------------------------------------------------------
  
  But if I add the following column of the primary key as a criterion of the order, the query becomes very slow.
  SQL > select * from hist3 by reference, palette;
  
  ------------------------------------------------------------------------------------------
  | ID | Operation | Name | Lines | Bytes | TempSpc | Cost (% CPU). Time |
  ------------------------------------------------------------------------------------------
  | 0 | SELECT STATEMENT | 1000K | 82 M | 22523 (1) | 00:04:31 |
  | 1. SORT ORDER BY | 1000K | 82 M | 200 M | 22523 (1) | 00:04:31 |
  | 2. FULL RESTRICTED INDEX SCAN FAST | HIST3_PK | 1000K | 82 M | 2524 (2) | 00:00:31 |
  ------------------------------------------------------------------------------------------
  
  If I look at the execution plan, I don't understand why a SORT statement should be needed, as data already take the IOT in the order requested.
  
  Any thoughts?
  Thomas

  There are various ways how Oracle sorts VARCHARs.
  When you create an index on a VARCHAR column, sort order is binary.
  Try ' alter session set nls_sort = "BINARY" "and run your query."

• Select Insert on the same partition: RELATIONAL() - REMOVE a GLOBAL INDEX

  Hi all

  I found on v$ sqlarea suite statament:

  insert / * + / RELATIONAL PARALLEL ("TABLENAME") ("TABLENAME", 1) ADD NESTED_TABLE_SET_SETID NO_REF_CASCADE * /

  in "SCHEMA." "" TABLENAME ' partition ('DAY20151015')

  (

  Select / * + RELATIONAL("TABLENAME") PARALLEL("TABLENAME", 1) * /.

  *

  a 'schema '. " TABLENAME' partition ("DAY20151015") ".

  )

  Remove the global index

  This is a query that reads and writes the same data on the same partition!

  I think that it is generated by Oracle, but I don't undestand what he does.

  Can you give me some explanation or assistance on this query?

  Thank you very much

  This is a query that reads and writes the same data on the same partition!

  Well not - enough is NOT that.

  The RELATIONAL indicator causes unnest Oracle object data and insert the data from the attribute itself rather than the object.

  The indicators used are usable only by Oracle-c ' is why they are undocumented. You can find songs on the web, but practically everything you find is "best estimate".

• 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.

  Not valid. This makes no sense and breaks all the rules of scope-resolution. And if it is in a single database, or uses tables in databases, is not relevant.

  Each object must be particularly well identified. If you cannot do this:

  select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a
  

  3 objects cannot share the same alias. Example:

  SQL> select * from (dual, dual) d;
  select * from (dual, dual) d
                     *
  ERROR at line 1:
  ORA-00907: missing right parenthesis
  

  You need to combine objects - by using a join union or similar. He will have to be done as follows:

  SQL> select * from (select * from dual d1, dual d2) d;
  select * from (select * from dual d1, dual d2) d
         *
  ERROR at line 1:
  ORA-00918: column ambiguously defined
  

  However, we need to have unique column in a projection of SQL names - so the join of the need to project a unique set of columns. So:

  SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
  
  DUM DUM
  --- ---
  X   X
  
  SQL> 
  

  I suggest that you look carefully at what opportunities are and how it applies in SQL - and ignore if the referenced objects are local or remote, because it has no effect on the basic principles of scope-resolution.

• Emergency aid! How can I run in the same block diagram two separate labview codes each with a diferent execution timings?

  Dear all.

  I have 2 progrlams application in the same schema. the intention is to use the 2 different when excuting programs for different applications, and each have to stop and start button, of course, I'll have to stop master. But when I run the program, it works as a program in time, it's the 1st block which I make active only, when I tried to activate the second block, that won't work, works only when I stopped the1st one. So, he wants your help, how can I solve my problem. Here I am attaching some of my programs.

• How to run several programs simultaneously on the same block diagram

  Hi all

  I want to run three instruments simultaneously on the same schema. One is a control position for linear drives, other is an optical micrometer and the third is a digitizer card. When using tabs of the controls, the linear actuator Vi is the only thing that seems to work (confirmation on the front panel) but the optical micrometer show no indication on the front panel, but runs in background. I used a tab control to consume less space on the front panel. Someone can help me solve this problem where I can carry several bolts on a single diagram and could even see on the front panel. I enclose my VI.

  Thanks for the help!

  I can't open your VI, but in general; Either you use a loop with all the instruments in the same loop, or separate loops each with no wires between them that forces the execution order. You have none of this?

  Tab control is purely visual, and has nothing to do with the execution.
