• How to select the csv data stored in a BLOB column as if it were an external table?

  Hi all

  (Happy to be back after a while! )

  Currently I am working on a site where users should be able to load the data of csv (comma is the separator) of their client machines (APEX 3.2 application) in the Oracle 11.2.0.4.0 EE database.

  My problem is:

  I can't use an external table (for the first time in my life ) so I'm a little clueless what to do as the csv data is stored by the application of the APEX in a BLOB column, and I'm looking for an elegant way (at least SQL PL/SQL/maximization) to insert the data into the destination table (run validations by a MERGER would be the most effective way to do the job).

  I found a few examples, but I think they are too heavy and there could be a more elegant way in Oracle DB 11.2.

  Simple unit test:

  drop table CBC purge;

  drop table dst serving;

  create table src

  (myblob blob

  );

  create table dst

  (num number

  , varchar2 (6) str

  );

  Insert in src

  Select utl_raw.cast_to_raw (1; AAAAAA ;'|| Chr (10) |

  2; BATH; »

  )

  Double;

  Desired (of course) output based on the data in table SRC:

  SQL > select * DST;

  NUM STR

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

  1 ABDELKRIM

  2 BATH

  Does anybody know a solution for this?

  Any ideas/pointers/links/examples are welcome!

  Haha, wonder about regexp is like the blind leading the blind!

  However, it's my mistake: I forgot to put the starting position setting (so 1, 2, 3,... was in fact the starting position, not the nth occurrence. duh!)

  So, it should actually be:

  select x.*
  ,      regexp_substr(x.col1, '[^;]+', 1, 1)
  ,      regexp_substr(x.col1, '[^;]+', 1, 2)
  ,      regexp_substr(x.col1, '[^;]+', 1, 3)
  ,      regexp_substr(x.col1, '[^;]+', 1, 4)
  ,      regexp_substr(x.col1, '[^;]+', 1, 5)
  ,      regexp_substr(x.col1, '[^;]+', 1, 6)
  from  src
  ,      xmltable('/a/b'
                passing xmltype(''||replace(conv_to_clob(src.myblob), chr(10), '')||'')
                columns
                  col1 varchar2(100) path '.') x;
  

  Note: that's assuming that all the "columns" passed in the string won't be lame.

  If one of them might be null, then:

  select x.*
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 1)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 2)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 3)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 4)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 5)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 6)
  from   src
  ,      xmltable('/a/b'
                passing xmltype(replace(';'||replace(conv_to_clob(src.myblob), chr(10), ';')||'', ';;', '; ;'))
                columns
                  col1 varchar2(100) path '.') x;

  Partha thanks it works now.

  Still, I made a small change to my querry.

  Select ta_acct, shift, created_on track_alerts where to move is: shft and TRUNC (created_on) = TO_DATE (select double sysdate,'MON-DD-YYYY "");

  For this statement, it does not work.

  of course not...

  first: sysdate returns a date so no need of conversion here

  and

  second SYSDATE includes time, so your application should look like this:

  Select ta_acct, shift, created_on in track_alerts where to move is: Shift and TRUNC (created_on) = trunc (sysdate)

  or

  Select ta_acct, shift, created_on in track_alerts where to move is: shft and created_on > = trunc (sysdate) and created_on<>

• The number of heartbeat for the host data warehouses is 0, which is less than required: 2

  Hello

  First, I created the cluster, no problem with that, so the DRS storage was created and now I can see in the Summary tab

  "The number of heartbeat for the host data warehouses is 0, which is less than required: 2".

  I search the Web and there are similar problems when people has only a single data store (the one that came with ESXi) and need to add another but in my case... vcenter detects any...

  Thank you

  You probably only have local data warehouses, which are not that HA would require for this feature (pulsations datastore) to work properly.

  You will need either 2 iSCSI, FC 2 or 2 NFS volumes... Or a combination of the any of them, for this feature to work. If you don't want to use this feature, you can also turn it off:

  Because in the second example you also select rows that have a nonzero component.

  The first example selects only rows that are 00:00:00

• Recommended value for the BAM data expiration time

  Hello
  
  Can someone tell me what is the recommended value for the BAM data expiration time?
  
  Enterprise Server default is 24 hours, but I would like to be able to raise the average runtime instance after several months. Is it reasonable to the value of the time-out value a high value? Or it will have an impact on the performance of BPM/BAM?
  
  Thanks in advance.
  
  Best regards
  CA

  Normally, we keep the BAM data expiration time at halfway with 24 to 72 hours. For historical reports that you are looking for the Data Mart / Data Warehouse DB are more logical. This database stores the data forever and takes pictures at longer intervals, normally 24 hours. These data are not in time real normally then because a capture instant is only taken once per day but will give you historical reports that you are looking for. The data from this database structure is almost identical to the BAM DB.

• For the complex data type, how to generate the Dll with compatible interface to C/C++

  Hello

  I used the Labview FPGA module to develop test equipment. Now, I need to write a driver that is to be a Dll with compatible interface to C/C++ for this equipment. So that my client who is familiar with C/C++ can call the driver without any study on labview. But I had a few problem on how to convert labview for C/C++ data complex data type. To clearly explain to my question, I have attached a simple example. (see attachment) I try to generate a Dll for the attached example VI and get the the function prototype at the head of the files as below:

  ' void OpenFpgaReference (LStrHandle * RIODevice, TD1 * errorIn, LVRefNum * FPGAVIReferenceOut, TD1 * errorOut).

  As you have known, the type of data "LStrHandle * RIODevice" and "LVRefNum * FPGAVIReferenceOut" Labview data format are. C/C++ do not have this kind of data type and can not reconige it. As a result, I can't call the Dll of C/C++ programming language. How to convert these two data type of labview for the C/C++ compatible data format, and then build the Dll? Anyone know about this?

  The answer is really apprecaited! Thank you in advanced.

  As I found in the following article:

  LVRefNum is the name of resource of LabVIEW VISA or refnum, and "it is impossible to convert LabVIEW VISA name of resource or refnum VISession valid ID."
  This means that external code modules can not access & control the session VISA which is open by labview. But for my purposes, I will not attempt to access this VISA extenal code(C/C++) session. I just hope that save this session VISA in the external code once I opened it in Labview dll; and pass it to the labview dll when needed. While I have not need to login again when I need to control the device. Is it possible to do?

  A LVRefNum is really just a single int32 value. Its meaning is useless for other environments than those who created it so that you Michael not any what in C/C++ caller but pass it back to other functions in your DLL, but this often isn't a problem at all.

  You can take the following statement of the LabVIEW extcode.h headers and add them to your delabviewed header files to make it work in such a way.

  #define Private (T) typedef struct T # _t {void * p ;} * T}

  Private (LVRefNum);

  The LStrHandle you must set a standard C string instead in your export DLL and document what is the size of the string buffer should have if it is an output parameter.

  TD1 error clusters should also be divided into their parameters (C compatible) separate for all items or just to the left of suite entirely.

• Filter KeywordFilterField customized for the tabular data model

  I am currently looking for the rows in the table that is filtered through the KeywordFilterField. The underlying data are in table form:

  Contact {name, phone, etc etc}

  The KeywordFilterField shows only what I pass to it (Contact.Name) by calling setSourceList() and filters that the channels in the list. So if I get the numbers, which will return a list empty, because none of the Contacts have numbers in their names.

  However, what I want to do is query the table, like a SQL query, retrieve lines that correspond to a part of Contact.Name or Contact.Phone. (Remember this application don't use SQLite.) I'm using RMS to persistent storage and I created my database and queries of base by hand.)

  Is there a way I could customize/override the filter query so that the KeywordFilterField calls my query functions rather than it's default filter String? It is a base with search CRUD application. I use KeywordFilterField because it's everything I need.

  Any help would be useful.

  It is possible with a text field and a list field, this way you can make your own personalized search for the keyword filter field does not search your data the way you want. In addition, I know that the keyword filter field is broken and that it was returning always completely incorrect search result for me.

  Here's an overview of what to do. Some things I can't tell you how for example to what is happening in the function "searchContacts" since it is up to you to write the code to do whatever custom search you want.

  class CustomKeywordFilterScreen extends MainScreen implements FieldChangeListener, ListFieldCallback
  {
      //just a slightly modified edit field for use in entering keywords
      private CustomKeywordField _filterEdit;
      //a standard list field
      private ListField _countryList;
  
      //temp variable to hold the last keyword searched so we don't search for it again
      //you'll see this used later on

• PLSQL - to_date coded for the American date strings regardless of the machine?

  I do a code to deal with some issues that originally come from an Excel... There are some fields being a string containing a date value. So my code is to take the string and turn it into a variable date so I can insert it into a date field Oracle. The format of the dates in Excel is like this: "DD/MONTH/YYYY" "MONTH" is written in American English.

  So, if I do something like this:

  Select to_date (April 1, 2013 ',' DD/MONTH/YYYY ')

  in: myDate

  OF THE DOUBLE

  ;

  It works fine when I run it on my own machine English/American.

  But... When I run the same on my client machine (which is in another country, Brazil)... I get an error "Invalid month.

  Of course, if I had to do this:

  Select to_date (' 01/ABR/2013 ',' MON/DD/YYYY "")

  in: myDate

  OF THE DOUBLE

  ;

  Then it works fine.

  And... It seems that even if their machine settings are Brazilian, they provide the date field in Excel (which they provide) in a USA-English format.

  Then... What is a good way I can interpret their date field (which is in English)? I hope for a command that completes the to_date function that also tells the Oracle "interpret this" DD/MONTH/YYYY"format, where the MONTH is written in American English" regardless of work on a non-English machine?

  Not sure it's what you're asking. Have you tried TO_DATE (April 1, 2013 ', ' DD/MONTH/YYYY', 'NLS_DATE_LANGUAGE = American') when inserting?

• Using the interval function works well for the end of the month

  
  I need to be able to get 1 year, 2 years, etc and also 1 month 2 months ago for each date in the calendar.  I can use the function of the INTERVAL for the most part, but it does not work if there is 1 month (year) would produce an invalid date.

  For example, the monitoring generates an error.

  Select TO_DATE (February 29, 2012 ')- INTERVAL of '1' YEAR  FROM DUAL; 

  Select TO_DATE('31-MAR-2011') - MONTH INTERVAL '1' FROM DUAL;

  Is there a way to get chosen to return on February 28, 2011?

  Thank you for your help.

  Hi, Sandy,

  ADD_MONTHs always returns a valid DATE.

  ADD_MONTHS (TO_DATE ((29 février 2012 ', «DD-MON-YYYY»), 12 * n))

  will return on February 29, n years after 2012, if this year is a leap year and February 28 this year, if it is not a leap year.

  In general

  ADD_MONTHS (d, m)

  Returns the date months after DATE m d.  If d is located near the end of his month and months m months in the future is for several days, then ADD_MONTHS returns the last day of that month.  By example, if d is on 31 March and 1 m, then ADD_MONTHS returns the last day in April (1 month after March), because there is no day 31 in April.

• Logic required for the following data

  
  Hi all

  I have the procedure that I call a cursor to retrieve records. This query returns the following data

  DI	SZ	DII	CWT	Back to top	down
  9 1/2	9.625	8.921	36	18	1602
  13 1/2	13.375	12.515	61	19	1962
  18 1/2	18.625	17.755	87.5	20	503
  26	26	24.75	105	20	103
  9 1/2	9.625	8.835	40	1602	3858
  7	7	6.276	26	1683	6352

  I want to print only those values...

  9 1/2	9.625	8.921	36	18	1602
  9 1/2	9.625	8.835	40	1602	3858
  7	7	6.276	26	1683	6352

  As you can see in these first values and down overlap.

  I tried several ways to sort the query on the fields and have a logic, but I always get an extra line that is not overlapping.

  Can someone give me please the logic to get the desired result through conditions of procedure/function/formula

  Thank you

  Hey Maher,

  Thanks for the reply, but I'm looking at some generic logic /Algorithm, I don't want to play with a fixed set of values. Values can change with the evolution of other structures.

  Kind regards

  I showed with fixed values for explanation.

  You can use my select statement on your table

  Select * from

  (select di, dii, ctw, sz, offset (down) on ldown (top control)

  of )

  where downstairs > = nvl (ldown, down);
