• Gears - error when you try to insert values into a table with multiple columns

  Hello

  I started playing with the gears and SQlLite today and I get an error when I try to insert values into a table with multiple columns.

  I have:

  var db = google.gears.factory.create('beta.database');
      db.open('developerSet');
      db.execute('create table if not exists Developers (DeveloperName text, DeveloperAge int)');
  
      var devName = "Davy"
      var devAge = 32;
  
      try {
          db.execute('insert into Developers values (?, ?)', [devName, devAge]);
          alert('success');
      }
      catch (e) {
          alert(e);
      }
  

  I get the error:

  net.rim.device.api.database.DatabaseException; insert into developers values (?,?): SQL logic error or missing database.

  I use this reference: http://code.google.com/apis/gears/api_database.html

  Everything works if I have only one field as:

  var db = google.gears.factory.create('beta.database');
      db.open('developerSet');
      db.execute('create table if not exists Developers (DeveloperName text)');
  
      var devName = "Davy"
      var devAge = 32;
  
      try {
          db.execute('insert into Developers values (?)', [devName]);
          alert('success');
      }
      catch (e) {
          alert(e);
      }
  

  I use the plug-in Visual Studio 2.0 for 2008 that are running Windows XP SP and Simulator 2.13.0.56

  Yes, a SQLite database will persist between battery pulls.  The database is registered either to internal MEM or removable media (not the device memory), depending on which is available on your device.

  In general, its not considered a best practice to remove your table as soon as it is empty and re - create it again when you want to add data.  This adds extra overhead fresh for the final, delete and insert first for a given table.  Instead, define and finalize your drawing before you create your table.  Once created, review the static schema.

  That being said, for development purposes, it may be easier to provide an easy way to drop your tables while you develop your schema.

  See you soon,.

• Call a select stmt with multiple columns inside another column

  Hi all
  
  I have a question about the appeal of a select statement, which is to have multiple columns inside another select statement.
  
  I know that we can use inline views to retrieve data from another table within a query as shown below.
  
  SELECT (SELECT dname FROM dept WHERE deptno = e.deptno), deptno, sal FROM emp e;
  
  Now, I'm going to pull the loc also column within the same view of inline. But oracle is not allowing me to do the same thing.
  
  Is there a way we can achieve the same thing because I don't want to hit the area two times table each time for each emp record.
  
  Appreciate your valuable suggestions.
  
  Thank you
  Madhu K.

  Maybe just a simple outer join?

  select ut.subscriberid

• Declare a type of table with multiple columns

  I have a table with a column of type, and I want to create one with two columns.

• ComboBox with multiple columns

  Is it possible to make a ComboBox with two columns in the drop-down list box?

• Group by returning multiple columns in a single request

  Hello
  
  Sorry to ask this simple question, I suppose, but here's my problem.
  
  I am building a query to get to say the smallest user_id of workers in society by Department.
  
  The query goes like:
  
  Select emp... Department,
  min (EMP.user_id)
  employee emp
  Emp.department group
  
  It gives me the smallest user by Department id, which is what I want. But how can I also get the name of this person?
  
  I know that the condition of 'min' distinguishes a single record (there are no two people with the same user_id in the Department).
  But how can I also get the name without turning the query above in a subquery that I would like to once again a link to the table of employees?
  
  I know that the following works, but I don't think it's the best option:
  
  Select v1.department,
  v1.user_id,
  Emp1.name
  employee emp1.
  (select emp... Department,
  min (EMP.user_id)
  employee emp
  Group emp.department) v1
  where emp1.user_id = v1.user_id
  
  
  This is just one example of data. This is the principle which I don't understand.
  
  Any advice would be much appreciated.

  Hi, Cyril.

  To find the name of the person who has the lowest user_id

  SELECT    department
  ,         MIN (user_id)   AS lowest_user_id
  ,         MIN (name) KEEP (DENSE_RANK FIRST ORDER BY user_id)  AS person_with_lowest_user_id
  FROM      emp
  GROUP BY  department;
  

  'MIN (name)' above means that if there is a link for the lowest user_id, you will choose the candidate with the first name.

  If you want to display several columns in the row with the lowest user_id, you must have an expression of 'KEEP (DENSE_RANK...)' separate for each column. In this case, you will find may be easier to use the RANK or the analytical ROW_NUMBER in a subquery, like this:

  WITH  sub_query  AS
  (
       SELECT  department
       ,     user_id
       ,     name
       ,     col2, col3, col4, col5
       ,     RANK () OVER ( PARTITION BY  department
                             ORDER BY          user_id
                      )  AS r_num
       FROM     emp
  )
  SELECT     *     -- or list all columns EXCEPT r_num
  FROM     sub_query
  WHERE     r_num = 1;

  I run a XMLEXISTS query to return documents that contain a specific search template. The search model is based on two distinct XPATHS. I tried to create an XML Index structured to support the request. While I can make it work when I specify that a XPATH, I can't make it work when I specify both.

  This should work better, with the caveat explained above:

  SELECT t.*
  FROM extendeddata t
  WHERE XMLEXISTS('declare default element namespace "urn:iso:std:iso:20022:tech:xsd:camt.054.001.02";(::)
                 /Document/BkToCstmrDbtCdtNtfctn/Ntfctn[Acct/Id/IBAN=$iban]'
          Passing Xmlcontent,
                  'XXXXXXXXXXXXXXXXXXXXXX' AS "iban"
             )
  and XMLEXISTS('declare default element namespace "urn:iso:std:iso:20022:tech:xsd:camt.054.001.02";(::)
                 /Document/BkToCstmrDbtCdtNtfctn/Ntfctn[Ntry/CdtDbtInd=$ctddbtind]'
          Passing Xmlcontent,
                  'DBIT' as "ctddbtind")
  AND rowinsertdate >= TO_DATE(' 2014-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
  AND rowinsertdate < TO_DATE(' 2014-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
  ;
  

  (see how the predicates in each XQuery expression corresponds to the structure of the index)

  BTW, this kind of "DIY" XMLEXISTS works just as well.

  It emulates what we would have hoped for a single XMLExists in the first place:

   12                 , CTDDBTIND VARCHAR2(4)  PATH 'Ntry/CdtDbtInd'
   13         ) x
   14    WHERE x.iban = 'XXXXXXXXXXXXXXXXXXXXXX'

How do the records to retrieve all the columns above, but with a unique combination of fixture_name and reorder_number. It has no keys defined on the table.
  
  I guess that it is a simple problem but the fact I'm trying to retrieve all the columns I'm stumbling.
  
  Thanks in advance.

  I don't see a column named reorder_number. Do you mean fixture_reorder_number or part_reorder_number_9?

  So, you want only one row for each distinct combination of fixture_name and some other column (I'll assume it's fixture_reorder_number). Does it matter which line? They will not necessarily have the same values for the other columns.
  The following query returns the one with the first pogname (in sort order):

  WITH     got_r_num     AS
  (
       SELECT  pogname, index#version, pog_model_status, pog_layout_type
       ,     pog_market_specific, pog_contact_number, fixture_name
       ,     ROW_NUMBER () OVER ( PARTITION BY  fixture_name
                                 ,                    fixture_reorder_number
                           ORDER BY        pogname
                         )         AS r_num
       FROM    sps_prod
  )
  SELECT  pogname, index#version, pog_model_status, pog_layout_type
  ,     pog_market_specific, pog_contact_number, fixture_name
  FROM     got_r_num
  WHERE     r_num     = 1
  ;
  

  If there be a tie (i.e. two or more lines with the same fixture_name, fixture_number and pogname first) and then the will be chosen arbitrarily.

  Instead of "ORDER BY pogname", you can ORDER all the other columns OR expressions, but you must have an ORDER byclause of analytics. You can do "ORDER BY NULL" If you really want pcik an arbitrary line.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements), and also publish the results you want from these data (or some examples of acceptable results).

• Report with multiple columns NUMBER of counts of the same table

  I am new to discoverer, so I'm a little lost.
  
  I work to create a report to show usage data and Knowledge Base of e-business. I have written using subqueries in SQL query that is in the format:
  
  Solution number | Soultion title | Solution views. Positive feedback | Negative feedback
  Title of 12345 _ 345 _ 98 34
  
  
  The entries 'Views', 'Positive' and 'Negative' are stored in the same table, so I do a count where setid = setid and usedtype = VS, then count where usedtype = usedtype and PF = NF
  
  Discoverer, I can get the number of solution, the title and THE totals but I can't seem to understand how to get an ACCOUNT for three different things from the same table in the columns on the same line.
  
  When I go on change map-> select the items once I select the option NUMBER of the UsedType column in the CS_KB_SET_USED_HISTS table, I can't select it again. I also found way now to add a column based on a query entered.
  
  If someone could help it would be much appreciated.
  
  Thank you

  Hello
  You can separate the column with a case or decode.
  for example to create 2 calculations:

  case
  When usedtype = "PF".
  then - that contain both
  0 otherwise
  end

  case
  When usedtype = 'NF '.
  then - that contain both
  0 otherwise
  end

  After that, you can create the aggregation count on those.

• Histogram with multiple columns

  I use a CFC to enter data in a database.  Data from looks like this

  Jan 100 cars

  Jan 150 trucks

  Jan 125 bikes

  Feb 112 cars

  Feb 132 trucks

  Feb 121 bikes

  etc.  I want a chart bar to see the numbers on the left and the month along the bottom.

  When I import it, it leaves two empty columns then shows the bikes from Jan.  When I add another series, it does the same thing.  What I want is for the data to be left aligned and have Jan and a column for each item, then have Feb and a column for each element.

  Coming from my data via

  event.result = inventory

  as Collection ArrayCollection;

  < mx:ColumnChart

  y=" 40 "

  ID ="

  myChart "

  dataProvider ="

  {inventory} "

  showDataTips ="

  true "

  selectionMode ="

  unique "

  width ="

  100% "height =" " 100% " >

  <! - vertical axis - >

  < mx:verticalAxis >

  < mx:LinearAxis " baseAtZero = ' true "

  < / mx:verticalAxis >

  < mx:horizontalAxis >

  < mx:CategoryAxis

  dataProvider ="

  {inventory} "

  categoryField ="

  sale " />

  < / mx:horizontalAxis >

  < mx:series >

  < mx:ColumnSeries

  Color ='

  #FFFFFF "

  xField ="

  month "

  yField ="

  sale " >

  < / mx:ColumnSeries >

  < mx:ColumnSeries

  Color ='

  #FFFFFF "

  xField ="

  month "

  yField ="

  sale " >

  < / mx:ColumnSeries >

  < / mx:ColumnChart >

  You need three ColumnSeries. Set the dataProvider of each directly (instead of setting for the ColumnChart) something like this:

  var car: ListCollectionView = new ListCollectionView();

  cars. List = inventory;

  cars.filterFunction = {function(item:Object):Boolean}

  return item ['category' / * or whatever your category field * /] == "cars."

  };

  Do something similar for the motorcycles and trucks. You can do something like this if you do not know the number of categories as well, but it's rather more complicated (and left as an exercise for the reader).

• Unique table with several columns or several tables split?

  A table with multiple columns inside or divided into several tables. Why?

  I have a table EMP that has column EMP_ID, EMP_NAME MGR_ID, MGR_NAME, SALARY, EXP_IN_MNTHS, EXP_IN_YRS... etc with multiple columns

  I have the following tables
  EMP-> EMP_ID, EMP_NAME

  Each row in the table emp thie represents a separate employee. I guess other columns in the emp table might be birth_date, social_security_number and status (by example, 'Active', 'Leave', 'complete'). Here's what an employee has (at least) one of. If there is a one-to-many relationship between an employee and an attribute, then you probably want another table for this attribute.

  BISHOP-> EMP_ID, MGR_ID, MGR_NAME

  There is a one-to-many relationship between employees and managers? In other words, an employee may have 2 or more managers? If Yes, then you need another table.
  If there is only a one-to-one relationship between employees and managers (in other words, if an employee is never more than 1 Manager) so why don't you just have a mgr_id column in the emp table?
  Managers are also used for? (This is often the case, as in scott.emp and hr.employees.) If so, do not store their names in the EME and tables of mgr. Store name (and date of birth and other information) in the table emp only and, if you need a table of Bishop, just the emp_id and mgr_id column.

  SAL-> EMP_ID, SALARY

  There is a one-to-many relationship between the employees and wages? In other words, an employee may have 2 or more treatments? If so, how will you use the values? Is a special treatments in some way, as it will be used more often than others? (In other words, you may have a current and past wages salary, but the last wages are rarely used.)
  If you never have more than 1 salary for a given employee, why not just have a sal column in the emp table?

  EXP-> EMP_ID, EXP_IN_MNTHS, EXP_IN_YRS

  There is a one-to-many relationship between the employees and what whether you store in this table?

  etc. with more tables

  What is the best based on

  (1) performance and data recovery
  (2) ease of use
  (3) maintainability

  A one-to-many relationship requires an additional table. If an employee can have up to 3 managers, don't have mgr1, mgr2 and mgr3 columns in the emp table. Use a separate table, with up to 3 lines for the same employee, instead.
  For 1-1 relationships, it is usually best to not have separate tables.

  Of course, it is possible.  According to what the text file looks like to, you can create an external table that treats the text file as if it were a table.  Otherwise, you can always read the file in PL/SQL, using the utl_file package and INSERT of PL/SQL commands.

  You have problems whatever you wantt?  If so, your zip code and explain what the problem is.

  Whenever you have any questions, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the exact results you want from these data, so that people who want to help you can recreate the problem and test their ideas.  In this case, also post a small sample of the text involved file.

  If you ask about a DML operation, such as INSERT, then INSERT statements, you post should show what looks like the tables before the DML, and the results will be the content of the table changed after the DML.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Concatenate multiple columns in a single string

  Hello
  
  I use Oracle 11.2, how can I concatenate values from multiple columns in a string with an SQL:
  
  create table testTb (number (5) classId, class varchar2 (32));
  
  Insert into the testTb value (101, 'room101');
  Insert into the testTb value (101, 'room201');
  Insert into the testTb value (101, 'room301');
  Insert into the testTb value (202, 'room444');
  Insert into the testTb value (202, 'room555');
  
  I would like to generate the result as following:
  
  Class 101 is room101, room201, room301
  202 class is located in room444, room555
  
  Thank you

  Please post sample data.
  11.2 you can use LISTAGG:

  SQL> select 'Class '||classid||' is in '||listagg(classroom, ', ') within group (order by classroom)
   str
    2  from   testtb
    3  group by classid;

• How to make the Web Gallery with 3 columns of thumbnails?

  Hi all

  I used the gallery photo web to build a few sites, but always with thumbnails in a single, vertical, column within a framework that scrolls. and I have never mch liked this scroll bar.

  I came across this page:

  http://www.mariannekolb.com/recent.html

  that, as I look at the code, cannot even make use of web photo gallery, but is very similar.

  in any case, someone in this group has an idea how this miniature of multiple column (without scroll bar) is completed?

  Thank you

  the person that I'm building the site hate scrolling.

  In this case, choose a skin different (several to choose) and / or modify the CSS code to meet your needs.  jAlbum forums can help you.

  How to select entire groups or to multiple recipients in MAIL, rather than one at a time?

  One way is to use the app to create a group with the intended recipients. Then when composing the email just type the group name in the To: field.
