• ORA-01445: cannot select ROWID, or sample, a view of join without key - preserved table form w/report and LOV

  I create a page "Form on a Table with Report" (APEX 5). Table I has 3 columns: cat_key, item_value, item_description. The cat_key is a foreign key in a table with columns cat_key, cat_value. I created the report and everything works fine.  The page of the report shows my domain cat_key in number, so I want it instead to display the cat_value. I change the field cat_key to a text based on LOV, select my LOV and now when I view the page of report I get the "'ORA-01445: cannot select ROWID from where sample, a join without key preserved table view ' error." The report uses the ROWID as a link to the edit page field.

  If I use the same tables and even shared LOV in a report page interactive, it works fine.

  What I am doing wrong?

  This is a limitation of the IR Apex will rewrite your query to a query that includes the lookup table and the columns. So now you have actually created a query on an inline view, which causes the error. You can see the query apex created when running in debug mode. APEX will join the table of choice with your primary table. For example from one of my IR:

  Select 'ID '...

  "MSL". "" HIS_COUNTRIES "=> my primary table

  ) ) b,

  (select rv_meaning d, rv_low_value r

  of msl_ref_codes_table

  where rv_domain = "JOHN".

  ) L1 = > query My LOV Lookup
  

  ...

  So, if possible, base your reports and forms on the real primary key, no rowid.

  You can also write the IR query with the search yourself:

  Select T1.rowid...

  of primary_table T1

  look_table L1

• Gel application - "the required samples are not yet acquired.

  Hello

  I have a vi that controls a test bench. The vi was created using Labview 8.6. Vi works fine and controls to the test correctly when running on the pc where it was created in the full version of software development (which is not converted into a stand-alone executable).

  The problem occurs when I create an executable file and try to run it in another pc. Initially the application seems to work ok but then after a random time (anything between 30 seconds and 12 hours), the application starts to turn slowly and then loses communication with the hardware (cDAQ-9178). After what happened when I opened MAX and try to run the task I get an error message that says that «some of the requested samples are not yet acquired...» »

  When the application starts to slow down, I see a reduction of the available physical memory and one of the CPU usage increases to 100%.

  I built the application using Labview 2012 and use MAX 5.3.1 on the pc hosting the executable file.

  Below, I have included a screenshot of the area of the block diagram which is probably more relevant to solve this problem. In MAX, the task is set to continuous samples, 1 k samples read at the rate of 1 k.

  Anyone have any suggestions for me to try please?

  Thank you

  So now, you can try what BCL@Servodan suggested. Create and launch tasks with DAQmx before your loop and see if it helps. Remove the timed loop would be also advised, and you set the sampling frequency before the normal while loop, as in the official example.

  This would not require too much effort and can help...

• Required SQL query

  Hello

  Suppose I need to check the number of records of 30 tables in the oracle database in a particular schema, it may have hundreds of tables.
  How to check with simple sql query.

  I know that under method,

  Select count (*) from
  Table1, table2, table3... table30;

  But I need in format below. If I use Group by we will get but we must specify all 30 tables to groupby, is any alternative group instead of keep all 30 tables

  
  SELECT TABLENAME, COUNT (*)
  OF table1, table2, table3... table30

  Group of table1, table2, table3... table30;

  Try the following query if all tables are present in the same pattern in the case otherwise you must use dba_tables:

  Abhijit

  Abhijit,

  Now that you have already re-created the table, it would be difficult to find the exact cause. But I suspect it could happen due to the creation of table in a way not recommended the use of quotes.

  If you use double quotes while creating the table/column names, you must always use capital letters. Better is not not to use quotes in all. Here is an example of a test that could be the cause of your error.

  SQL > drop table test;

  Deleted table.

  SQL > create table test ("col1" nvarchar2 (200), col2 varchar2 (200));

  Table created.

  SQL > select Col1 from test;

  Select Col1 from test

  *

  ERROR on line 1:

  ORA-00904: "COL1": invalid identifier - it is him you got. Even if there is col1 column in the table, but I'm unable to select due to the bad way to appoint.

  SQL > drop table test;

  Deleted table.

  SQL > create table test ("COL1" nvarchar2 (200), col2 varchar2 (200));

  Table created.

  SQL >

  SQL > select col1 from test;

  no selected line

  The test case above apply to the tables as well.

• Extraction of a node in an XMLtype table - selection of the previous query

  Hey all,.
  
  I work with a server Oracle 11 g r2 and basically need to be able to analyse and select nodes from it. I spent hours scouring the net and reading the manual oracle xml db trying to find an appropriate solution to my problem, but I can't seem to identify the correct way to do it. I have some experience in programming, but none with databases oracle, sql or xml in general so forgive me if this is a trivial question.
  
  OK, so the question:
  
  I have a very simple XML file saved under catalog.xml and it is as follows:
  
  <>Catalog
  < cd >
  < title > hide your heart < /title >
  < artist > Bonnie Tyler < / artist >
  < Country > UK < / country >
  < company > CBS Records < / company >
  < price > 9.90 < / price >
  < year > 1988 < / year >
  < CD >
  < cd >
  Empire Burlesque < title > < /title >
  < artist > Bob Dylan < / artist >
  < country > USA < / country >
  < company > Columbia < / company >
  < price > 10.90 < / price >
  < year > 1985 < / year >
  < CD >
  < / catalogue >
  
  Now, I want to be able to extract the title of the given cd a certain artist. So, for example, if the artist is "bob dylan", the title should be "empire burlesque".
  
  Now I created an XMLType table in Oracle as follows:
  
  CREATE BINARY XMLTYPE STORE AS XML BINARY XMLType TABLE.
  
  I then load my xml file into oracle by:
  
  Insert the BINARY values (XMLTYPE (BFILENAME ('XML_DIR', 'catalog.xml'), nls_charset_id ('AL32UTF8')));
  
  So far so good.
  
  Now for the part of the excerpt:
  
  First of all I've tried:
  
  SELECT extract (b.object_value, ' / catalogue/cd/title ')
  Binary b
  WHERE existsNode (b.object_value,'/catalog/cd [artist = "Bob Dylan"]') = 1;
  
  EXTRACT(B.OBJECT_VALUE,'/CATALOG/CD/TITLE')
  --------------------------------------------------------------------------------
  
  < title > hide your heart < /title >
  Burlesque Empire < title > < /title >
  
  1 selected line.
  
  
  
  It did not work because the xml file was all in 1 row then I realized that I had to split my xml in separate rows. Doing that, I had to convert the nodes < title > a virtual table using the functions XMLSequence() and table(). These functions convert nodes two title returned by the extract() function in a virtual table composed of two XMLType objects, each of which contains a single title element.
  
  Second test:
  
  SELECT value (d)
  Binary B,
  Table (xmlsequence(extract(b.object_value,'/catalog/cd'))) d
  WHERE existsNode (b.object_value,'/catalog/cd [artist = "Bob Dylan"]') = 1;
  
  VALUE (D)
  --------------------------------------------------------------------------------
  
  < cd >
  < title > hide your heart < /title >
  < artist > Bonnie Tyler < / artist >
  < Country > UK < / country >
  < company > CBS Records < / company >
  < price > 9.90 < / price >
  < year > 1988 < / year >
  < CD >
  
  < cd >
  Empire Burlesque < title > < /title >
  < artist > Bob Dylan < / artist >
  < country > USA < / country >
  < company > Columbia < / company >
  < price > 10.90 < / price >
  < year > 1985 < / year >
  < CD >
  
  2 selected lines.
  
  
  It's better because it is now divided into 2 different lines so I should be able to make a selection - where, and then select the title from the artist.
  
  However, this is where I have questions, I tried to literally hours but I can't understand how to use the results of the query above in my next. So I tried to use a suquery in this way:
  
  Select extract (sub1, ' cd/title')
  Of
  (
  SELECT value (d)
  Binary B,
  Table (xmlsequence(extract(b.object_value,'/catalog/cd'))) d
  ) sub1
  WHERE existsNode (sub1,'/ cd [artist = "Bob Dylan"]') = 1;
  
  However, sql * plus displays an error:
  
  ORA-00904: "SUB1": invalid identifier.
  
  I've tried dozens of variations to try to use subqueries but I simly can't do things.
  
  I heard you can do also do this using variables or pl/sql, but I don't know where to start.
  
  Any help would be greatly appreciated I tried everything at my disposal.

  This should help you get started!

• selection of values to query where clause

  Hi guys, it of maybe a silly question but do not know if I approach the solution in the correct engineering.
  
  At the top of my form, I framed that the user fills out the different values. These values are then used to refine the query results in the block below. I know that I can go in the datablock being interrogated and set the where the clause equal to the value of the text boxes above, but I don't feel it is the right place to do it.
  
  If I do like this when the above text box is empty, it returns no results when infact I want to ask all if the values are left white. So should I put it in motion pre? If so how should we do?
  
  Any help would be greatly appreciated.
  
  Thank you.

  In the trigger of the QUERY before block you, just put the value in the corresponding element

    :block.name := :ctrl.selection ;

  Works perfectly! I'm wondering now if I had the - ticked instead of +. Seems as if could be the answer and if it does not work in the future I'll check everything here first. Thanks for your time and your help.
