• How to get the sql query result?

  Hello

  Currently I use LV2012 to connect to an Oracle database server. After the Oracle Express and Oracle ODBC driver facilities/settings made.

  I managed to use the SQL command to query the data through my command prompt window.

  Now the problem is, how to do the same task in Labview using database connectivity tools?

  I have build a VI to query as being attached, but I have no idea of what range to use to get the result of the query.

  Please help me ~ ~

  Here is a piece of code that I use to test the SQL commands, you can use the part that retrieves the results of sql.

  It is also possible to get the rear column headers, but it's for the next lesson!

  I use JDeveloper 11.1.2.3.0. I have a page where I've set up an af:query and an array of result. The problem is that I can't get the exact query that is used during the execution of this component in a managed bean method. Is it possible to get the query string that is run within the af: query?

  Hello

  Method of the ViewObject getQuery() returns what you need;

  You can replace the executeQueryForCollection(), and prior to calling super, you can print the result of getQuery() method:

  public void executeQueryForCollection (rowset Object,

  Object [] params,

  {int noUserParams)

  System.out.println ("SQL =" + getQuery());

  call the super method here...

  @Boris - you don't have to have an additional connection to the database. The thing is that if you don't have additional logging, Oracle will give you only the ROWID of the records and if it is not the same database or something has changed (as "alter table... move"), ROWID is not relevant. If you enable additional logging, you will get more information on the line (like the other columns or PK) which will help you a lot to identify RELEVANT changes. As I said, it is not mandatory, but as you say, if you want extra logging, it must be turned on BEFORE the changes in the database.

  Hope that's clear,

  Any help please,.

  Hello

  It is not very hard in SQL * more.

  First of all, put your query in a script file, like this one, called hour_query.sql:

  --     hour_query.sql          Show data from my_table for a given time period
  
  PROMPT     The data below shows the period from &1 to &2
  PROMPT
  
  SELECT     *
  FROM     my_table
  WHERE     accounting_start_time     <= '&2'
  AND     '&1'               <= accounting_stop_time
  ;
  

  Parameters & 1 and & 2 are beginning and end of time, for example "2011-08-12 09:00".
  Note that this does not use TO_DATE. If you have incorrect strings in columns that must be DATEs, no errors occur.

  Assuming that hour_query.sql is located on p:\some_dir\, you want another script that runs hour_query.sql 24 times, like this one, which I will call all_hours.sql:

  @p:\some_dir\hour_query  "2011-08-12 09:00:00"  "2011-08-12 10:00:00"
  @p:\some_dir\hour_query  "2011-08-12 10:00:00"  "2011-08-12 11:00:00"
  @p:\some_dir\hour_query  "2011-08-12 11:00:00"  "2011-08-12 12:00:00"
  ...
  

  (I just did 3 hours to test. You can easily make that 24 hours).

  The following code creates and then runs all_hours.sql:

  -- Turn off SQL*Plus features that interfere with raw output
  SET     FEEDBACK     OFF
  SET     PAGESIZE     0
  SET     VERIFY          OFF
  
  -- Write all_hours.sql
  SPOOL     p:\&some_dir\all_hours.sql
  
  WITH     got_start_time     AS
  (
       SELECT TO_DATE ( '2011-08-12 09:00:00'
                          , 'YYYY-MM-DD HH24:MI:SS'
                   ) AS start_time
       FROM    dual
  )
  SELECT     '@p:\some_dir\hour_query  "'
      ||  TO_CHAR ( start_time + ((LEVEL - 1) / 24)
            , 'YYYY-MM-DD HH24:MI:SS'
            )
      ||  '"  "'
      ||  TO_CHAR ( start_time + ( LEVEL      / 24)
            , 'YYYY-MM-DD HH24:MI:SS'
            )
      ||  '"'
  FROM    got_start_time
  CONNECT BY     LEVEL <= 3     -- You can make this 24, or any other number
  ;
  
  SPOOL     OFF
  
  -- Turn on SQL*Plus features turned off earlier
  SET     FEEDBACK     ON
  SET     PAGESIZE     50
  -- Except VERIFY.  leave that OFF while all_hours runs
  --SET     VERIFY          OFF
  
  -- Run all_hours.sql
  @p:\some_dir\all_hours.sql
  
  SET     VERIFY     ON
  

• Satellite 1800-814: how to measure the temperature of the processor?

  I replaced the radiator component on my laptop as it freezes suddenly during the operation. Now everything seems to be better, but still a last question. How to measure the temperature of the processor?

  Dominic displays only HDD temp and MBM profile for 1800-224 display cases and the cpu. But if I can use this profile? Any other ideas how to meausre CPU temp?

  MBM shows me around 40 to 49 ° C for the cpu. Is this normal or too high just to run windows?

  Thanks in advance

• How to select only the part by using the sql query

  Hello

  I have the task to retrieve only the integral of the input text by using the sql query.

  The entry is as follows

  Entry for the price setting

  $12.5 (FYI without space)

  $ 12.5 (FYI single space)

  $ 12.5 (double space FYI)

  $12.5 (FYI multiple space)

  $12.5 (FYI multiple space)

  Output expected of 12.5

  The price is the type varchar2 column in the store_price table.

  Please let me know how to achieve this.

  Thanks in advance.

  If this is always the case that you get a $ followed by a number of places, you can use something like:

  Select to_number (ltrim ('$ 12.5',' $')) DOUBLE

  or

  SELECT ltrim ('$ 12.5',' $') OF double

  but take care of your nls_numeric_character settings if they are defined so that, for example, a comma is the decimal separator, you will have a problem.

• How to get the SQL if I get exception

  I get this exception and do not know what was the actual sql with the variables of liaison who was executed.
  
  
  
  sqlmesg = error in the select query to retrieve the segment associated with a pair of cables: ORA-01006: there is no bind variable
  
  y at - it a way to get the real sql executed so I know what mistake I did.

  I thought your question was about how to view the SQL statement and bind variables in the exception. The answer to that is to put variables in the exception message.

  The root cause of the problem seems to be that your dynamic SQL statement may require 3 or4 variable bind but your USING clause specifies always 4 values if the underlying SQL statement has 3 positions, it will lead to an error.

• How to convert the hierarchical query of SQL Server (CTE) to Oracle?

  How to convert the hierarchical query of SQL Server (CTE) to Oracle?
  
  WITH cte (col1, col2) AS
  (
  SELECT col1, col2
  FROM dbo. [tb1]
  WHERE col1 = 12
  UNION ALL
  SELECT c.col1, c.col2
  FROM dbo. [tb1] AS c INNER JOIN cte AS p ON c.col2 = p.col1
  )
  DELETE one
  FROM dbo. [tb1] AS an INNER JOIN b cte
  ON a.col1 = b.col1

  Hello
  Something like this maybe:

  DELETE FROM dbo.tb1 a
   WHERE EXISTS (
    SELECT 1
      FROM dbo.tb1 b
    WHERE a.co11 = b.col1
        AND a.col2 = b.col2
     START WITH b.col1 = 12
    CONNECT BY b.col2 = PRIOR b.col1)
  

  Although you need to do here is to check that CONNECT it BY SELECT, returns records you wait first, then the DELETION should work too.

• How to find the sql queries executed in one day with the sql and runtime text

  Hi Experts,

  Please reply urgent.

  Thanks in advance

  Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

  AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

  To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?
