• Insert row into table 2D retaining the previous values

  Amendment of data entered in a 2D array and also displayed a table. When the time rolls 3 columns of data are held and then created line. Problem is the line moves downwards, but the previous data is not stored. I tried using shift register, but that only auto markings lines table to fill as the iteration of the loop. Looks like a basic really simple problem but going round in circles on this one there...

  In this case, the function 'Replace table subset' is what is needed to replace the last values in line with the current values of the user interface.

  On the evolution of the time, an addition occurs.

• Dial the node library with cluster table feature using the pointer of table data

  Hi all.

  I am writing a wrapper of LabVIEW for an existing DLL function.

  The service was, as one of its parameters, an array of structures.  The structure is very simple, containing two integers.  I use the call library function node to access.

  In Labview, I created an array of clusters, when the cluster has two integers of 32 bits as members.  So far so good.

  Now, I have to pass this in the node library function call.  I use here in trouble.

  I used the LAVA so the topic in the knowledge base as my main sources of information, although I read a lot of topics in the forum on the subject too.

  I don't understand I could write a new function that takes as a parameter a struct with the size as the first member and an array as the second, and I might just do this and do call the regular service, but I was hoping to do more simply.

  The file function C LabVIEW generates for me the COLD Lake when I choose "To adapt to the Type" and "Data in the table pointer", the prototype he expects is:

  int32_t myFunc (handful of uint32_t, uint16_t channel,
  int32_t FIFOnumber, Sub data [], int32_t numWords, int32_t * actualLoaded,.
  int32_t * actualStartIndex);

  And the prototype of the function in my DLL is

  int myFunc borland_dll (DWORD channel, channel of Sina,)
  FIFOnumber int, struct mStruct * data, int, int numWords * actualLoaded, int * actualStartIndex);

  It sounds like a match for me, but it doesn't work (I get garbage in the data).  The topic referenced above LAVA, I realized it would work.  This isn't.

  If I have to cast the data to the pointer-to-pointer I get when I generate c code in my wiring to a CIN struct and by generating, then I seem to get what I expect. But it seems to work when I choose "pointers to handles" too, and I'm expecting data table pointer to give a different result.

  Is it possible to get it works directly, or I have to create a wrapper?  (I am currently using LabVIEW 2011, but we have customers using 2009 and 2012, if not other versions as well).

  Thank you.

• Select a table returned in the result of the query

  Hi, I'm trying to find a way to query a table name that I'm back to a different query. I am doing this in pure SQL and PL/SQL, if I can.
  
  Here's the situation. I have a table called FILES, a table called TYPE and an unknown number of different reference tables with different names.
  
  Each entry in the FILE has a reference to a TYPE id, and each entry type is a varchar that contains the name of a table reference, such as PHOTO_INFORMATION, PDF_INFORMATION or XML_INFORMATION.
  
  I want to be able to extract the data from the reference table for any data file. So with a file id, I question TYPE to get the name of the reference table (IE, "PHOTO_INFORMATION" back) then the request it is at this table for all of its columns, using the reference id in the FILE table.
  
  The thing is that I wish it were generic, so that I can just add an entry to AA_TYPE and a new table for this type, and then I can ask her but I want, through the FILE table. The reason is that there are some data that is common for all files, and I would like to that data in one place.
  
  Here is my paintings, I have two reference tables of the sample to the bottom "AA_FILETYPE1" and "AA_FILETYPE_PHOTO".
  

  CREATE TABLE  "AA_FILES" 
     (     "FILE_ID" NUMBER, 
       "FILE_NAME" VARCHAR2(4000), 
       "FILE_TYPE" NUMBER, 
       "REFERENCE_ID" NUMBER, 
        CONSTRAINT "AA_TEST_FILE_PK" PRIMARY KEY ("FILE_ID") ENABLE
     )
  /
  
  CREATE TABLE  "AA_TYPE" 
     (     "TYPE_ID" NUMBER NOT NULL ENABLE, 
       "REFERENCE_TABLE" VARCHAR2(4000), 
        CONSTRAINT "AA_TYPE_PK" PRIMARY KEY ("TYPE_ID") ENABLE
     )
  /
  
  CREATE TABLE  "AA_FILETYPE1" 
     (     "REFERENCE_ID" NUMBER, 
       "DATE_MODIFIED" DATE, 
       "SUMMARY" VARCHAR2(4000), 
       "TOTAL_VALUE" NUMBER(5,2), 
        CONSTRAINT "AA_FILETYPE1_PK" PRIMARY KEY ("REFERENCE_ID") ENABLE
     )
  /
  
  CREATE TABLE  "AA_FILETYPE_PHOTO" 
     (     "REFERENCE_ID" NUMBER NOT NULL ENABLE, 
       "DATE_TAKEN" DATE, 
       "CAMERA_NUMBER" VARCHAR2(4000), 
       "WEATHER_CONDITIONS" VARCHAR2(4000), 
       "CONSULTANT_NAME" VARCHAR2(4000), 
        CONSTRAINT "AA_FILETYPE_PHOTO_PK" PRIMARY KEY ("REFERENCE_ID") ENABLE
     )
  /

  Here's an example query I would use:
  

  select * from (select REFERENCE_TABLE from AA_TYPE where TYPE_ID = AA_FILES.FILE_TYPE) where REFERENCE_ID = AA_FILES.REFERENCE_ID;

  So who withdrew all the columns in the reference given in AA_TYPE table based on an entry in AA_FILES.
  
  I'm not entirely sure how to do this, or if this is possible even without using PL/SQL.
  
  I'm open to suggestions on how to achieve what I want with a different design of table, I am a student and I'm not really experienced in database design. (My first design of database class isn't until next year!)
  
  Thank you very much!

  Sorry about the confusion about file_id = 3, I meant the insert in the third I've included. I did not indicate the id_fichier in my inserts since it is the main key and it auto increments.

  It is important to post of the CREATE TABLE and INSERT statements that work. All those who want to help you to will want to recreate the problem and test solutions. Also, do not use strings for all entries. If the column is a NUMBER, use a NUMBER in the INSERT statement. If the column is a DATE, use a DATE or a function that returns a DATE.
  So you should post something like:

  insert into AA_FILES(FILE_ID, FILE_NAME, FILE_TYPE, REFERENCE_ID) values (1, 'test-photo-1.jpg',  1,  1);
  insert into AA_FILES(FILE_ID, FILE_NAME, FILE_TYPE, REFERENCE_ID) values (2, 'test-xml-1.jpg',    2,  2);
  insert into AA_FILES(FILE_ID, FILE_NAME, FILE_TYPE, REFERENCE_ID) values (3, 'test-photo-2.jpg',  1,  2);
  -- The value file_type=1 immediately above was not in your original data, but seems to be what you meant.

  To give you my workplace, I'm applying in Application Express. A user has entered the number '3' the file_id (I'm not worried about the distinction between passing in the id_fichier and the name of the file, I just my application one application or the other).

  Now, run a query that will get related data which table it is stored in. I don't know the name of the table at design time, as that particular file may be of any type (each of which has a different table name). However, with a the file_id, I have a file_type (in aa_files) which refers to an entry in aa_type.

  I see. You could add even add new tables after this query is written. As long as the new table has a column named reference_id, and there is a line for the new table in aa_files, the following query should work.

  >

  select FILE_TYPE
  from AA_FILES
  where FILE_ID = 3
  

  I stored the name of the table, I need to ask for the rest of the data in aa_type at design time, so using the file_type value, I can get the name of reference_table:

  select REFERENCE_TABLE from AA_TYPE where FILE_TYPE = 1
  

  In the sample data, you have validated, Type_de_fichier = 2 on the 3rd row. I've changed that in my example 1 revised data.
  Be very careful that your explanation fits your data. You talk to people who know about your application, and it is very easy for them to be induced in error or confusion.

  Now the '1' is here that the first query would return. I would like to use a subquery to combine these two queries into a single (I think?). This second query would return "AA_FILETYPE_PHOTO", which is the reference table.

  So I have the reference table, which is a name of table to another table in my database. It contains the data that I'm actually looking for. I want it for this particular file (file_id 3), and in aa_files, I have a value of "reference_id", which refers to the respective line in the reference table. File_id 3, the reference_id is 2.

  select * from AA_FILETYPE_PHOTO
  where reference_id = 2
  

  If the above query gets me my final data.

  Now, I've been watching substitution values and bind variables, here's another way to explain what I want:

  Explanation step by step below is very useful. It would be more useful if each step uniquely and gavce movement results given the sample data and an example of setting (3 in this case)

  -- get the file_type from aa_files for the desired file
  EXEC :file_type := (select file_type from aa_files where file_id = 3);
  

  That we will call the step step (a) above.
  Step (a) sets: Type_de_fichier 1 (given my corrected sample data)

  -- get the reference table from aa_types using the file_type
  EXEC :reference_table := (select reference_table from aa_type where type_id = :file_type);
  

  That we will call the step step (b) above.
  (B) sets the stage: reference_table to 'AA_FILETYPE_PHOTO '.

  -- get the reference_id from aa_files for the desired file
  EXEC :reference_id := (select reference_id from aa_files where file_id = 3);
  

  That we will call the step step (c) above.
  (C) sets the stage: reference_id 2

  -- using the reference table and reference id for the desired file, get the rest of the data
  select * from :reference_table where reference_id = :reference_id;
  

  Not sure if this makes it more clear or not.

  Yes, it helps a lot.

  Basically I have a table full of table names. How do I write a query that pulls one of these table names and it then queries?

  You need SQL dynamic, because you can't hardcode a table name in the query that you normally would be.
  How dynamic SQL works normally (and the functioning of this example) are that the query is built by using a variable. In SQL * more (as shown below), you can simply use a variable substitution instead an identifier hardcoded, and that's what it takes to make the dynamic query from SQL * more resolves the substitution variables before sending the code for the compiler. I don't know much on the Apex, but I bet there's some way to do dynamic SQL in the Apex, too.
  So the dynamic part here should include step d, since you can't hardcode the name of the table in the query.
  Until we can step (d), then, did they to us to do the steps (a) and (b) to obtain this file name. In the example blelow, I used a separate, preliminary request to get the & table_name...
  Step (c) could be made in the main query, using a subquery or a join. However, I chose to step (c) in the preliminary motion, as well as steps (a) and (b), since it's the same table same step (a). In this way, step (d) must refer to a table.

  Here's (finally) how to make this work in SQL * more:

  ACCEPT     file_id     PROMPT     "Enter the file_id (a number, e.g. 3): "
  
  -- Preliminary Query, to set table_name
  
  COLUMN     reference_id_col     NEW_VALUE     reference_id
  COLUMN     table_name_col           NEW_VALUE     table_name
  
  SELECT  f.reference_id          AS reference_id_col
  ,     t.reference_table       AS table_name_col
  FROM      aa_files     f
  JOIN     aa_type          t     ON     f.file_type     = t.type_id
  WHERE     f.file_id     = &file_id
  ;
  
  --     Main Query
  
  SELECT  *
  FROM     &table_name
  WHERE      reference_id     = &reference_id
  ;
  

  The results, account required to the data from the sample I posted above, and the & file_id 3, are:

  `                      CAMERA_    WEATHER_        CONSULTANT_
  REFERENCE_ID DATE_TAKE NUMBER     CONDITIONS      NAME

• Extract a specific node of XMLTYPE value

  I have a piece of code that puts an answer Google geocoding in an XMLTYPe variable.  I then use lines similar to the following to retrieve values such as address and location:

  px_xml.EXTRACT('/GeocodeResponse[1]/result['||pn_result_number||']/formatted_address[1]/text()').getstringval();
  

  It's a pretty lazy way of just looping through my results and picking a specific value.

  Now, I need to extract just the addresses zip_code of XML component and can't do in the same way.  Someone at - it ideas?

  A call to the example is:

  https://maps.googleapis.com/maps/API/geocode/XML?address=London+Eye & Bounds = 49.90878, - 7.69042. 60.88770,-0.83496 & key =

  but you need to add your own key to operate.  There are several components of the address and I just want to identify who has the type "zip_code".

  Thank you!

  It's a pretty lazy way of just looping through my results and picking a specific value.

  And what about using a more friendly approach, XMLTABLE namely:

  Extract data from complex XML of XMLType with nodes parents containing several internal nodes

  Use an XPath predicate to target only the required component, for example:

  select x.long_name
  from xmltable('/GeocodeResponse/result'
         passing px_xml
         columns
           long_name   varchar2(200) path 'address_component[type="postal_code"]/long_name'
       ) x

  How can I create an index on these tables of the ordered collection to improve performance?

  I found the example at http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_rewrite.htm#ADXDB5859 but am not able to apply to this particular case...

  Thank you in advance...

  If the schema is not annotated and XS: Integer and XS: String are mapped to types of data NUMBER and VARCHAR2 (4000), so you must use in your query to avoid typecasting unnecessary operations.

  You must also use XMLTABLEs chained when accessing a parent/child instead of a FLWOR expression relationship, otherwise the CBO cannot rewrite the XQuery query correctly (maybe it's fixed in the latest version).

  If you make these changes, the plan should show the cleaner predicates:

  SQL > SELECT EVENT_ID, MESSAGE_ID, ACTION_TYPE, ACTION_SUB_ID, ACTION_TIMESTAMP

  2 FROM test_table

  3 XMLTABLE ('/ monitoring ')

  4 COLUMNS XML_CONTENT OF PASSAGE

  5 WAY of VARCHAR2 (4000) EVENT_ID "ID."

  6 actions for XMLTYPE PATH 'action '.

  (7) T1,

  8 XMLTABLE ('/ action')

  Shares of PASSAGE 9 COLUMNS

  NUMBER of ACTION_SUB_ID 10 PATH "actionSubId."

  11 PATH of VARCHAR2 (4000) ACTION_TYPE "type."

  12 WAY of NUMBER ACTION_TIMESTAMP 'time '.

  (13) T2

  14 WHERE EVENT_ID IS NOT NULL

  15 AND ACTION_SUB_ID IS NOT NULL

  16;

  Now, if it is still necessary, everything boils down to choosing a technique for index NULL values:

  -FBI

  -bitmap image

  Choose the one that best fits your data, the selectivity and activity on the tables.

• Object Table of XMLType vs single column of XMLType Table

  What are the differences between the XMLType table object and a table with a single column of XMLType?
  
  It's
  
  CREATE TABLE XMLType xml_table;
  
  and
  
  CREATE TABLE xml_table (xml_field XMLTYPE);
  
  That should be used and when? Both may be declared to be aware of schema.

  The main difference is that an XMLType object array allows the use of the XML DB Repository to store and retrieve XML content.
  The relationship between a resource and its content is maintained by a "pointer" (REF XMLType) line in the XMLType table:

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb03usg.htm#ADXDB4223
  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb03usg.htm#BJFBDEJE

  Tables based on the patterns of XMLType (including the associated nested structure) can also be created automatically through recording scheme, which is very convenient when the pattern becomes complex.
  In addition, a registred schema-compliant documents that go into the repository automatically stored in the table by default (see the annotation xdb:defaultTable).
  We can also use ACLs to control access to specific rows in a table of object XMLType.

  This is not possible with XMLType columns in a relational table.

  Hello

  Namespace problem.
  You must declare it in the XQuery Prolog:

  DELETE FROM document
  WHERE XMLExists( 'declare default element namespace "urn:hl7-org:v3"; (::)
                    $p/document/id[@root=$root_value]'
                   passing object_value as "p",
                           '03d6a2cd-fdda-4fe1-865d-da0db9212f34' as "root_value" )

• Difference between an XMLType table and one table with an XMLType column?

  Hi all
  
  Still trying to get my mind on all that XML stuff.
  
  Can someone explain briefly the difference between:

  create table this_is_xmltype_tab of xmltype;

  and

  create table this_is_tab_w_xmltpe_col(id number, document xmltype);

  What are the advantages and disadvantages of each solution? How are they really different?
  
  Thank you
  
  -Mark

  Sorry Mark, as far as I know it is not a real difference despite the fact that you can use the table with the column (ID), probably more effective for document-focused while driving the query via the ID column and anything else I can think off automatically about XMLType contra XMLType table columns is that (as far as I KNOW) you can not use a column of XMLType to shred the data into it via WebDAV o FTP. But then again I never really tried to do an XMLType column-based. Alternatives, for example, a binary XML column begins with a column of $ sys_nc_oid which is indexed, so in principle you shouldn't need an ID (number) column that has an index (a read also on http://www.liberidu.com/blog/?p=494). If there has been non-null that you could use this index for document oriented applications.
