• Query to find records with more than 2 decimal places.

  I have written the below query to find records with more than 2 decimal places, but it is returning records with decimal places 1 & 2. 
  The datatype of the AMT column is NUMBER (without any precision).
  
  SELECT amt  FROM amount_table
   WHERE substr(amt, instr(amt, '.')) LIKE '.%'
         AND length(substr(amt, instr(amt, '.') + 1)) > 2

  select fee_amt from amount_table  where line_number = 100. this query shows the output as below
  
  fee_amt
  
  41591.1
  
  The fee_amt column has number as datatype (without precision)
  
  Why it is automatically shown rounded off as 41591.1?

  You use SQL * more your front end?

  SQL * Plus has a fixed width to display all columns. The default for numbers is 10 characters. If necessary, SQL * Plus will be round a number or the use of scientific notation, to represent the number of the expected number of characters.
  You can use the SQL * more "SET NUMLARGEUR" to change the default view for all the numbers of orders, or "COLUMN" to set a sepcific format in an individual column.
  If you explicitly convert your channel numbers in a query, SQL * Plus adjusts the column width to whatever is needed. For example

  SELECT  TO_CHAR (fee_amt, 'TM')     AS fee_amt_d
  

  "TM" is the default format; You can call TO_CHAR with a single argument, if you prefer.

• Find records overlapping start and end dates

  Hi all
  
  I have a table with begin and end date columns. I need to find the records that overlap with a few values in corresponding column.
  
  Table: MG_AUTH_AGNT

  You cannot declare a record type dynamically.

  You can, if you were really desperate, use dynamic PL/SQL construction instead of simply using dynamic SQL. It is very rare, however, that dynamic SQL is actually a good idea and it is extremely rare that the dynamic PL/SQL use is a good idea. You call yourself a newbie makes me strongly suspect that you really want to focus on learning to do things normally don't not focusing on features that are rarely used correctly and frequently abused.

• Form does not display the 'new' SQL database records

  I have a PDF form that retrieves data from a SQL Server.  The fields of

  record in a menu drop down and clicking a button called 'bridge '.
  The problem is that the drop-down list does not display new records that
  have been recently added to the database.  I have to open the form
  in the designer, and then save it, (* note - I change anything at this point.)
  Then, when the form is opened upward in Adobe drop-down list show all
  the documents, including the new ones.  I even put a manual on refresh
  form to try to solve the computer problem has not helped. Seriously left speechless.

  Any help is greatly appreciated.

  
  Here is my code for the menu drop down.

  Search with the command 'class name' node
  var nDBIndex = 0;
  While (oDB.nodes.item (nDBIndex) .className! = 'command')

• How to find records given a child parent key

  I have a main table that is parent for several children tables. I want to display a button to delete a record in the primary table. I would have preferred to see the this key conditionally so when a master record's child records, I don't show button Delete and no error is raised.
  Of course I could scan each child table to find the child records, but I think that must be a generic method
  
  How can I tell if a given parent key has child records?
  
  Thanks in advance

  PS: I use 10 gr 2

  There is no magic/generic way to verify that a main line has no associated detail line. As says Pavan, you must decide which detail the tables to check and them using SQL as usual. (In fact, there is a quick way - you remove the line if there is no child rows with foreign keys which is not cascade, the delete will fail; but of course you can't use this in case the deletion succeeds and the user never wants to push the button).

  An addition to the Pavan response: DO NOT under any circumstances to count all records in the table of every detail. Everything you want to know is, is it at least 1 record retail at least 1 tables. No need to count the lines 100 or 1000...

  You can do it like this in your PL/SQL

  FUNCTION check_children(p_master_id IN INTEGER) RETURN BOOLEAN
  IS
  
    CURSOR c_child1  IS
    select 1 from child_table_1 where master_id = check_children.p_master_id;
  
    CURSOR c_child2 IS
    select 1 from child_table_2 where master_id = check_children.p_master_id;
  
    -- etc for all child tables
  
  l_rec_present integer := null;
  
  BEGIN
  
      OPEN c_child_1;
      FETCH c_child_1 INTO l_rec_present;
      CLOSE c_child_1;
  
      IF l_rec_present i= 1 THEN
          -- there is a child in child_table_1
          RETURN TRUE;
      END IF;
  
      OPEN c_child_2;
      FETCH c_child_2 INTO l_rec_present;
      CLOSE c_child_2;
  
      IF l_rec_present i= 1 THEN
          RETURN TRUE;
      END IF;
  
  -- etc for each child; finally, if no child found:
  
     RETURN FALSE;
  END;
  

  This made sure that (1) you stop once you find any child, and (2) you get all NO_DATA_FOUND and TOO_MANY_ROWS exceptions thrown.

  Please check in Device Manager if the cd/dvd drive is correctly recognized.
  Additional if you can find the drive in the Device Manager, you could try to remove it and restart the laptop.
  After restarting the laptop should recognize the device again.
  Then you should check the functionality of the drive.

  We read the analog waveform records successfully in call back, and we look at samples - they are correct.
  We need to know the moment when trigger onset occurred for each acquisition.

  The data is read to the variable
  AnalogWaveform awf =...;

  and we do the following

  If (AWF. IsPrecisionTimingInitialized)
  {
  InitialXTimeSeconds = awf. PrecisionTiming.StartTime.WholeSeconds;
  InitialXTimeFraction = awf. PrecisionTiming.StartTime.FractionalSeconds;
  }

  The problem: InitialXTimeSeconds and InitialXTimeFraction are the same for all records and equal at the beginning of the task, i.e. time of the acquisition of the first record. What's wrong?

  Hey, I noticed that you posted this question in another forum here. Continue to work on this in this forum.

• SQL, find the MAX value and placing it as a QVariant

  I have a database that is loaded and defines the customerID as 0 which is ideal when the database is not be saved and restored, etc.  The question I have is that I added the possibility to users to restore a backup in the app, and now I have to do a query to select MAX (customerID) so that there is no duplicate CustomerID when you add or save items.  Here is the following code, I knew that I must settle, specifically the 0 highlighted in red.  I need zero to be the new customerID max value:

  int SettingsStorage::load(int& lastID, GroupDataModel *model)
  {
      // number of locations loaded.
      QSettings settings(m_author, m_appName);
      int loadedCount = 0;
  
      QVariant items;
      // Get the last customer id first.
      // ID's will be generated by incrementing this number
      // Note values coming from settings should be cast to the
      // required type.
       lastID = settings.value(m_lastCustomerIDKey, 0).toInt();
      items = m_sda->execute("SELECT * from items ORDER BY datefield");
      qDebug()<< "the ID" << items;
      // Load all the locations from the database.
      foreach( const QVariant& temp, items.value() ) {
          Location *p;
          if (loadLocation(temp.value(), p)) {
              model->insert(p);
              loadedCount++;
          }
      }
      return loadedCount;
  }
  

  Ive tried the following, but it doesn't seem to do anything:

  int SettingsStorage::load(int& lastID, GroupDataModel *model)
  {
      // number of locations loaded.
      QSettings settings(m_author, m_appName);
      int loadedCount = 0;
  
      QVariant items;
      // Get the last customer id first.
      // ID's will be generated by incrementing this number
      // Note values coming from settings should be cast to the
      // required type.
       QVariant endID = m_sda->execute("Select MAX(customerID) from items")
       lastID = settings.value(m_lastCustomerIDKey, endID).toInt();
      items = m_sda->execute("SELECT * from items ORDER BY datefield");
      qDebug()<< "the ID" << items;
      // Load all the locations from the database.
      foreach( const QVariant& temp, items.value() ) {
          Location *p;
          if (loadLocation(temp.value(), p)) {
              model->insert(p);
              loadedCount++;
          }
      }
      return loadedCount;
  }
  

  Any help will be loved and marked solutions.

  -Thanks in advance

  I was wrong about executeAndWait(). Somehow, I decided that you use the SqlConnection object, but seems his SqlDataAccess. So disregard my previous post. Keep your execute method, but you must change your code to something like this:

  QVariant endID = m_sda->execute("select max(customerID) as m from items");
  
  QVariantList vlist = endID.value();
  QVariantMap vmap = vlist.first().toMap();
  
  lastID = vmap["m"].toInt(&ok);
  

  So I changed your SQL query slightly and added "that m" so I will have something to refer later.

  Then I cast QVariantList because it is where are the results.

  Then because we know its going to be the only record, I took the 1st element in the list and converted to QVariantMap.

  Last step is to get the maximum.

  Should work this time

• Need help with Oracle SQL merge records according to date and term dates

  Hi all

  I need help to find this little challenge.

  I have groups and flags and effective dashboards and dates of term against these indicators according to the following example:

  GroupName	Flag_A	Flag_B	Eff_date	Term_date
  Group_A	THERE	THERE	20110101	99991231
  Group_A	N	N	20100101	20101231
  Group_A	N	N	20090101	20091231
  Group_A	N	N	20060101	20081231
  Group_A	N	THERE	20040101	20051231
  Group_A	THERE	THERE	20030101	20031231
  Group_B	N	THERE	20040101	99991231
  Group_B	N	THERE	20030101	20031231

  As you can see, group_A had the same combination of (N, N) flag for three successive periods. I want to merge all the time periods with the same indicators in one. Where entry into force will be the most early (underlined) time period and end date will be later (underlined)

  So the final result should look like this:

  GroupName	Flag_A	Flag_B	Eff_date	Term_date
  Group_A	THERE	THERE	20110101	99991231
  Group_A	N	N	20060101	20101231
  Group_A	N	THERE	20040101	20051231
  Group_A	THERE	THERE	20030101	20031231
  Group_B	N	THERE	20030101	99991231

  Thanks for your help

  Here's the DDL script

  It is the closest, I went to the solution
  

  
  

  I create two rows;

  Rnk1: partition by group name, order of eff_date / / desc: this grade will sort the records of the most recent and handed to zero for each group\

  Rnk2: (dense) partition by group name, flag_A, flagb: this grade for each combination of group\flag gives a number so that they are classified as "families".

  Then I use the function analytic min

  Min (eff_date) more (partition of GroupName, rnk2): the idea is that, for each Member of the same family, the new date is the min of the family (and the max for the date of the term), at the end I just need separate so that the duplicates are gone

  Now the problem. As you can see from the query below, records of 1 and 6 (as identified by rownum) are identified in the same family, because they have the same combination of flag, but they are not successive, so everyone must keep its own date of entry into force.

  If only I can make the distinction between these two that would solve my problem

  
  

  Query:

  
  

  Select rowNum,GroupName, flag_a, flag_b, eff_date, term_date, rnk1, rnk2

  , min (eff_date) more than (partition by GroupName rnk2( ) min_eff

  Of

  (

  Select rowNum,

  GroupName , flag_a , flag_b , eff_date , term_date

  rank() more than (partition by GroupName stopped by eff_date desc) rnk1

  DENSE_RANK() more than (partition by GroupName order by flag_A flag_B ( ) rnk2

  de dsreports . tmp_group_test

  ) order by rowNum

  Hi KSI.

  Thanks for your comments, you were able to distinguish between these lines highlight, but lost lines 2,3,4 which are supposed to have the same date min = 20060101.

  Please see the table wanted to see the final result I want to reach

  Thanks again

  This first answer is basically correct, but in the main query, you want to use the function MIN, not the analytical function aggregation and GROUP BY columns with common values, like this:

  WITH got_output_group AS

  (

  SELECT GroupName, flag_a, flag_b, eff_date, term_date

  ROW_NUMBER () OVER (PARTITION BY GroupName

  ORDER BY eff_date

  )

  -ROW_NUMBER () OVER (PARTITION BY GroupName, flag_a, flag_b)

  ORDER BY eff_date

  ) AS output_group

  OF tmp_group_test

  )

  SELECT GroupName, flag_a, flag_b

  MIN (eff_date) AS eff_date

  MAX (term_date) AS term_date

  OF got_output_group

  GROUP BY GroupName, flag_a, flag_b

  output_group

  ORDER BY GroupName

  eff_date DESC

  ;

  The result I get is

  GROUP_NA F F EFF_DATE TERM_DAT

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

  Group_A Y 20110101 99991231 Y

  N Group_A 20101231 20060101 N

  Group_A N 20051231 20040101 Y

  Group_A Y Y 20031231-20030101

  Group_B N Y 99991231 20030101

  which is what you asked for.
