• selection column of the table xml data type

  Hello.
  I tried the following example with xml as column name data type

• Change the length of a Table column (CHAR data type)

  Hi gurus,

  SQL > select * from version $ v

  BANNER

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

  Oracle Database 10g Release 10.2.0.3.0 - 64 bit Production

  PL/SQL version 10.2.0.3.0 - Production

  CORE Production 10.2.0.3.0

  AMT for Linux: release 10.2.0.3.0 - Production

  NLSRTL Version 10.2.0.3.0 - Production

  I need to increase the length of a CHAR of a table data type column (currently it's tank (3) and you want to change to char (4)). Here are more details on the table:-

  • Contains more than 20 million lines.
  • Table contains several indexes.
  • Table is referenced by several tables (about 60 tables) and it refers to several tables (about 3)
  • Table has 4 complex triggers. Triggers call procedures and packages.

  What I've tried so far

  
  

  1 disabled all triggers and ran ALTER statement to increase the length. It took hours and did not finish in a reasonable amount of time, even if no error, but it took more than 12 hours.

  2 tried DBMS_REDEFINITION package but it does not work with the standard version of Oracle 10 g.

  I think to try next

  I think same Optics:

  Say my name of the existing table is OLD_T1 where the length of column need to increase

  -Create a copy (with increased column length) table of OLD_T1, Say NEW_T1

  -Move data from in OLD_T1 to the new table NEW_T1

  -Lower OLD_T1 (or rename it to OLD_T1_TMP)

  -Rename NEW_T1 to OLD_T1

  -Create all indexes, triggers, constraints etc..

  I wish to confirm, if my approach is correct? Or someone has a better idea to do this?

  Please note: I know that the CHAR data type gives the problem but it is an old system and I don't have authority to change the design of database.

  Appreciate any comment/suggestion

  Thanks in advance

  > I mean, can any application break if it depends on fixed-length?

  Yes, because the code can be expected completed on the right areas.

• Use two assistants for the acquisition of data at the same time

  Hello

  I want to read multiple data channels of analog inputs on my DAQ hardware. However, when I try to create two separate data acquisition assistants for each entry, it gives an error saying "is reserved for the specified resource. The operation could not be performed as indicated "." Can't use two assistants for the acquisition of data at the same time?

  I have to add different channels in the same assistant DAQ? I tried, but I couldn't separate the data in different graphs.

  How does this work?

  Kind regards

  Allard

  You can't have multiple tasks of the same type (in this case inputs analog) on the same device.  Just so having 1 DAQ Assistant read all your channels and separate your channels for individual transformation.

• CHAR data type question

  Hi all
  
  This question is purely for updating my knowledge on the rules of comparison of data type for Oracle. I am referring
  [Types of oracle data | http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/datatype.htm#i1960]
  and
  [Datatype comparison rules | http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/sql_elements002.htm]
  
  So I understand that Oracle uses the semantics of white comparison comparing the CHAR data type. I was testing a few queries on the CHAR data type.
  

  SQL> SELECT col_1, LENGTH (col_1), col_2, LENGTH (col_2)
    2    FROM (SELECT CAST ('A' AS CHAR (2)) col_1, CAST ('A' AS CHAR (5)) col_2
    3            FROM DUAL)
    4   WHERE col_1 = col_2
    5  /
  
  CO LENGTH(COL_1) COL_2 LENGTH(COL_2)
  -- ------------- ----- -------------
  A              2 A                 5
  
  1 row selected.
  
  SQL> 

  But when I tried using the set operators to compare data from CHAR data type I got results that confused me.
  

  --DDL & DMLStatements For Sample Data
  
  CREATE TABLE TABLE_A
  (
  col_1 CHAR(10)
  );
  
  INSERT INTO TABLE_A(col_1) values ('A');
  INSERT INTO TABLE_A(col_1) values ('B');
  
  CREATE TABLE TABLE_B
  (
  col_2 CHAR(15)
  );
  
  INSERT INTO TABLE_B(col_2) values ('A');
  INSERT INTO TABLE_B(col_2) values ('B');

  For reviews of col_1 in the Table_A in Table_B col_2 I used two different methods:
  
  Using the sub-sub-queries/join method:

  SQL> SELECT a.col_1
    2    FROM table_a a
    3   WHERE a.col_1 IN (SELECT b.col_2
    4                       FROM table_b b)
    5  /
  
  COL_1
  ----------
  B
  A
  
  2 rows selected.

  I got the expected results. Now, I tried to achieve the same thing using a game operator (INTERSECT)
  Using Set operator (INTERSECTION):

  SQL> SELECT a.col_1
    2    FROM table_a a
    3  INTERSECT
    4  SELECT b.col_2
    5    FROM table_b b
    6  /
  
  no rows selected
  
  SQL> 

  I had to add the TRIM function to achieve the expected results:

  SQL> SELECT TRIM (a.col_1)
    2    FROM table_a a
    3  INTERSECT
    4  SELECT TRIM (b.col_2)
    5    FROM table_b b
    6  /
  
  TRIM(A.COL_1)
  ---------------
  A
  B
  
  2 rows selected.

  Could someone please explain why I get different results for the above mentioned methods? I hope that I don't miss any details in the documentation.
  
  Thanks in advance

  'If the select queries values of TANK with different lengths, then the returned value is VARCHAR2 with the length of the largest CHAR value."
  and
  'In queries using the set operators, Oracle does not make the implicit conversion between the data type groups.

  I guess that if the values are CHAR with lengths, then they will not be considered as being equal, even if it is the same value in both tables, bar the number of spaces at the end.

  I don't rely on the parameters of comparison; make it explicit - trim TANKS before being compared - or, better yet, don't use TANKS in the first place, replace them by of VARCHAR2.

• queues the IMAQ image data type

  I'm trying to run multiple queues in the same loop entering IMAQdx images from several cameras, and then save to AVI. After reading the site nor a little, I discovered that the reason why I get only the last image of each bucket, repeated on all frames in the AVI file, is that the IMAQ image data type stores only the memory location for the image, not the image itself data. However, I don't see a better solution for the queues of the actual image data. What conversion could be the fastest / are in charge of the processor the lowest?

  

  For each image you must initial Image space.

  You can use something like this:

  

  You need to add initialization camera (s) and AVI. You must add the multicamera feature. Stop recording is missing.

  No, u do not attend the general tab. you need to go to the Data Type and click the button change. you will see a list of logical column. In your case, you will need to find the logical column when u used to store your WorkingHour and click on the button with three love (close your logical column). Now you have expression builder where you put formula: EXTRACTS ("Ain_Access" TIME. "" "" Fact_Access '. "" Hours of work)

• selection of the first column of the clicked row data

  All,

  Scott,

  I used the expression below, but it works only when the column ID/first appears, but if you set a column to not show IE uncheck the show of the column attribute, then it cannot read this value.

  $(this.triggeringElement) .find ('td:first').text())

  is there a way to always get that ID/first column when figure is not on the report?

  Buddhist salvation,

  It seems to me that you would be better to use "Linear Mapping" in the palette of ANALYSIS "Suitable curve", but you should be able to get your code works by passing the name of the channel in this second parameter instead of an empty string variable.  You would have noticed that if you had OPTION EXPLICIT the first line of your code - always a good idea.

• A full import by using datapump will overwrite the target database data dictionary?

  Hello

  I have a 11G with 127 GB database. I did a full export using expdp as a user of the system. I'll import the created dump file (which is 33 GB) on the basis of data from 12 c target.

  When I do the full import on the 12 c database data dictionary is updated with new data. But as is it already contained data dictionary? It will also change?

  Thanks in advance

  Hello

  In addition to the responses of the other comrades

  To start, you need to know some basic things:

  The dictionary database tables are owned by SYS and must of these tables is created when the database is created.

  Thus, in the different versions of database Oracle there could be less or more data dictionary tables of different structure database,.

  so if this SYSTEM base tables are exported and imported between different versions of oracle, could damage the features of database

  because the tables do not correspond with the version of database.

  See the Ref:

  SYS, owner of the data dictionary

  Database Oracle SYS user is owner of all the base tables and a view of the data available to the user dictionary. No Oracle database user should never change (UPDATE, DELETE, or INSERT) ranks or schema objects contained in the SYS schema, because this activity can compromise the integrity of the data. Security administrator must keep strict control of this central account.

  Source: http://docs.oracle.com/cd/B28359_01/server.111/b28318/datadict.htm

  Prosecutor, the utilities for export cannot export the dictionary SYS base tables and is marked

  as a note in the documentation:

  Data Pump export Modes

  Note:

  Several patterns of system cannot be exported because they are not user patterns; they contain metadata and data managed by Oracle. Examples of system schemas that are not exported MDSYS SYS and ORDSYS.

  Source: https://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_export.htm#SUTIL826

  That's why import cannot modify/alter/drop/create dictionary database tables. If you can not export, so you can not import.

  Import just to add new Non - SYS objects/data in the database, therefore new data are added to the dictionary base tables (as new users, new tables, code pl/sql etc).

  I hope that this might answer your question.

  Kind regards

• Use of columns in the placeholder

  Hello, since I am a beginner to the reports. Can someone tell me what are the columns of the reserved space and how they are used in the reports? Where can I see examples of reports using the placeholder columns? Previously, I downloaded a pdf file of Oracle who told placeholder value column can be set in trigger prior report or using formulas. So, are they somehow like global variables in C, which can be used by all components of the report in the form of a variable binding?
  
  Thank you very much.

  So, are they somehow like global variables in C, which can be used by all components of the report in the form of a variable binding?

  Yes, you could say so.

  We use a column of space reserved for the title of reports and any places objects on the margins of the report by assigning the appropriate values in the avant-rapport-trigger and then using the columns reserved space in layout.

• Help with the problem of data type...

  Hi friends,
  
  I have a requirement. I have a warrant 2 guests (from and to). The data contained in the guests are like "Fall 2006", "spring 2006", "full of 2006", "Academic 2006"for a given year. " I have data from the year 2000 to 2008. The data type of the column duration in varchar. I have a report corresponding to this prompt. This report works well if it is not linked with the guests. If I have this tie with guests, its giving me results because in the report I gave filter as term is greater than or equal to ' fisrt_pv "(où first_pv est la variable de présentation j'ai utilisé pour mon d'invite de terme... comme second_pv sage est pour à terme rapide) and the term is less than or equal to"second_pv"."» So, if I put my guest (and) fall 2007 and (spring 2008 to) and run the report, its sends a fall 2007, Full 2000... Full2008, spring 2000... Spring 2008. It is because it is comparing the term based on letter of departure with all the other term. We know that the fall 2007 and spring 2008 are next to next semesters, is expected to see just a 2-column output. How do oracle know that?
  
  I have a term_number associated with this table numbered 1 to the spring of 2000, 2 Full, 3 for autumn 2000 2000, 4 for academic 2000... all the way up to academic 2008. I used this area to the command prompt to order because I want the guest to show as the spring of 2000, Full 2000, fall 2000 etc. instead of 2000 academic, University 2001... hope this field will be useful for you to analyze... I need your help to do this... If you need other info let me know... Thanks for your time n help...
  
  Kind regards...

  Yes. The problem is that your guests are CHAR, so the calculation "superior to" is done alphabetically rather than numerically. This digital keys.

  Create two columns to contain the term_number that match the values selected in your guests. Then the BETWEEN operator do not filter on numeric values. You can still view the CHAR values in your report, but now they will be in the range that you would expect.

• Initialize the cluster with data types different (lots of data)

  Hello

  I have data, which are composed of different data types. First of all, I have initialize cluster with these types of data and then "print" to light (photo). In case of photo data carries 8 characters than ja 4 floats. It was easy to initialize, but here's the question: How can I do this even if I have data that look like this (interpreter):

  floating point number

  name char [32]

  Short value [16]

  What I create loooong cluster which have a fleet of 32 characters, 16 short films? Or I can create these 'paintings' in a different way?

  THX once again

  -Aa-

  I suggest using the table-cluster and configuration of the cluster size to match the size of your berries, then package these groups together.  In terms of storage of LabVIEW, there is no difference between a group of

  floating point number

  Name1 tank

  name2 tank

  ...

  short value1

  short value2

  ...

  and a bunch of

  floating point number

  -> cluster shipped from

  Name1 tank

  name2 tank

  ...

  -> cluster shipped from

  short value1

  short value2

  So you can use the cluster table to get the right sizes rather than individually create all these values in a single giant cluster.

• Work with the first HP data types?

  I'm trying to get a clear understanding of the data types of HP Premium so that I can better exploit feature internal rather than copy and paste, edit, or having to retype. However, I can't find a tutorial, guide to style "quick start" or comprehensive information on this subject anywhere. Finally, I would like to do things like the following:

  (NOTE: I only list these questions in order to better explain what I'm looking for.) "There ARE no need to answer.)

  • Pass a list of expressions (sometimes solve() returns a list) in a function such as unapply() and run it on each item, rather than interpret the list as parameters
  • Precede the value of formula 1, "Y =" and then save the result in V1
  • Understanding type (x), type (X) and ('X') - I understand that X is a floating point number; x and 'X' they return all two DOM_IDENT, but are in that they also treated the calls function?  Or 'X' becomes X and then treated as a float value?
  • Is there a better way than unapply(), to replace by X-> x to a function, a function of return?
  • For example if: F1 = X-> Sin (x)
  • NOT a function: the seizure of F1 (x) returns the expression: Sin (x)
  • IS a function: unapply entry (F1 (x), x) returns the function: x-> Sin (x)

  Is anyone know if such a guide or tutorial exist, and if so, could you please point me to it?

• Resolve the conflict of data type of TestStand pragmatically in CVI

  Hello

  I'm porting a UI for the 2010 ICB/TestStand.  My problem with the badly planned spread data types defined custom.  While I can handle the MyTypes.ini and StationGlobals definitions, sequences that we are loading are originally the dialog box 'Type to the Type of conflict'.  The sequences that are loading have been created in previous versions of TestStand (3.1 and 4.0 for the most part).  The main reason why a 'conflict' is detected because the data types of the sequences can either have different indicators (for example, "modified") or updated dates.  The structure of the types are ALWAYS the same, so there is no danger by choosing the "wrong" data type  However, given that the "currently loaded" Type is one that "must" always be used, it would be great if the resolution could be resolved so that the operator never has to see the dialog box.  In our environment of manufacturing of these dialog boxes are considered errors.

  There are hundreds of files in sequence that could be affected.  The process to go through each of them individually and setting data types would be impractical (really, out of the question).

  I use TSUI_ApplicationMgrOpenSequenceFile() to open the sequence and can not find a way to settle the conflict resolution to automatically choose the "currently loaded.  Please let me know if there is a way to do it, and if so, provide an example.  Any other suggestions you might have would be welcome.

  Thank you

  JF

  (Either by the way - I meant "programmatically", not "pragmatic" in the subject heading)

  I tried your suggestion and I still get the dialog box when
