• Calculate totals for multiple columns

  I want to add totals for the two columns in a table and a total end with these two subtotals. I can not know how to do this and how to reference the rows and cells. Can someone please? Thank you. Deepa

  

  Give a name for each line of the footer... (For ex: FotterRow1, FooterRow2)...

  Then your code will work without a lot of complications.

  Sum (FooterRow1.TotalA1 + FooterRow2.TotalA2)

  Thank you

• CSS3 multiple columns and Internet Exploder

  I have developed a web page that needs a two column layout and has decided to use CSS3 to describe the columns: very simple:

  {.twocol}

  border-style: solid;

  border width: 7px;

  border-color: #0476ac;

  -webkit-border-radius: 20px;

  -moz-border-radius: 20px;

  border-radius: 20px;

  -moz-column-count: 2;

  -moz-column-gap: 20px;

  -webkit-column-count: 2;

  -webkit-column-gap: 20px;

  number of columns: 2;

  column interval: 20px;

  padding: 10px;

  height: 300px;

  }

  CSS bold described the two-column layout that I want.

  Looked in Internet Exploiter version 9 and it failed. And, since the text was missing I did the 'old skool' method:

  {.colLeft}

  Width: 410px;

  }

  {.colRight}

  Width: 410px;

  float: right;

  }

  Then in HTML:

  < section class = "twocol" >

  < div class = "colRight" >

  < p > right column of things comes here < /p >

  < / div >

  < div class = "colLeft" >

  Insert here the stuff left column < p > < /p >

  < / div >

  < / section >

  I have commented things in "BOLD" in my style sheet.

  Here's my question:

  Since I'm on the HTML5 Shiv, shouldn't that have created the support for multiple columns in CSS3 declarations or is it simply too complex?

  HTML5 Shiv, as its name suggests, is strictly for the support of HTML5 tags in pre - IE9.  It will not help you with CSS level 3.

• 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

  Thank you

  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,.

• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

• Make multiple columns while placing text in InDesign CC 2015

  I used to be able to drag all by placing a text file and press the right arrow key before releasing the mouse to create multiple columns within a text. Which seems more to work in InDesign CC 2015.

  Is this a bug or Adobe changed the way it works?

  I just tested in CC 2015 and CS6.

  What works is when you slide on a block of empty text with the text tool, by pressing the right arrow key divides the image into two columns. (This works also when creating other images).

  In both versions of InDesign, when you place a text file or Word, this shortcut does not work.

  We must therefore create first part of two columns of text, then place the text in the frame.

• 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

• GROUP BY with multiple columns.

  I have a little query on the GROUP BY clause.
  
  Sometimes, we will give several names of columns in GROUP BY. If it behaves in the same way as ORDER BY (multi-column) I wish I had an example where I can use GROUP BY multiple columns. in any case regardless of his behaviour, it will be really appreciated if someone can explain a scenario where GROUP BY with multiple columns can be used.
  
  I know about the use of GROUP BY aggregate functions, but using a single column.
  
  Thank you.. !!!

  No, not like that

  I think that Group by does not follow any order...

  If we execute like this

  SELECT registrationid, dateofbirth, sum (age) FROM prawin62 WHERE registrationid = 22 GROUP BY dateofbirth, registrationid.

  22     1/23/1975     54
  22     5/18/2011     330
  

  It will give the same result based on date of birth...

• Sort order incorrect in datagrid sort multiple columns

  Hello
  
  I'm a little confused about sort multiple columns in a datagrid. The following code sorts, but not the sort, I expect or what you are doing the thing about a coming O alphabetically before or after P. In my opinion, the code must sort stadt, vname by clicking on the city column, and name, the VNAME by clicking on the column name, but obviously he disobeys correctly? You see an error in the code or is this a bug?

  Allright! So the column index begins with zero don't step one! It was the first.

  Secondly, once you have defined your own sorter, you don't want the default behavior of the event to pass by so you will add

  Event.preventDefault ();

  just after myData.refresh (); line.

  Give it a shot. should work.

• How to load a multiple column table in the coherence of caches?

  How to load a multiple column table in the coherence of caches?
  I want to load a multi-column (about 20 columns) table in cache coherence. How to change the following code (spatially how to change the SQL SELECT statement)?
  Is the following select statement enough: Select the key, the value of EMPLOYEES ?
  

  public static void bulkLoad(NamedCache cache, Connection conn)
      {
      Statement s;
      ResultSet rs;
      
      try
          {
          s = conn.createStatement();
          rs = s.executeQuery("select key, value from table");

              }
          ...
          }
      catch (SQLException e)
          {...}
      }

  First of all, you need a class to hold your 20 fields:

  Then you can use it to store data in you original code

  public static void bulkLoad(NamedCache cache, Connection conn)

      try
          {
          s = conn.createStatement();
          String sql = "select key, value, value2, " +
                  "value3, value4, value5, value6, " +
                  "value7, value8, value9, value10 " +
                  "value11, value12, value13, value14, " +
                  "value15, value16, value17, value18, " +
                  "value19, value120 from table";
  
          rs = s.executeQuery(sql);
          while (rs.next())
              {
              Integer key   = new Integer(rs.getInt(1));
              Data data = new Data();
              data.setField1(rs.getString(2));
              data.setField2(rs.getString(3));
              data.setField3(rs.getString(4));
              data.setField4(rs.getString(5));

              data.setField8(rs.getString(9));
              data.setField9(rs.getString(10));
              data.setField10(rs.getString(11));

              data.setField12(rs.getString(13));
              data.setField13(rs.getString(14));
              data.setField14(rs.getString(15));
              data.setField15(rs.getString(16));
              data.setField16(rs.getString(17));
              data.setField17(rs.getString(18));
              data.setField18(rs.getString(19));
              data.setField19(rs.getString(20));
              data.setField20(rs.getString(21));
              cache.put(key, data);
              }
          ...
          }
      catch (SQLException e)
          {...}
      }    
  

  Of course your data object would need the appropriate field names and you will have no channels for all types. It must also implement equals and hashCode and ideally PortableObject.

  I need to perform queries dynamically and the return values. I need to retrieve the values of the queries in a single column only by concatenating multiple columns. I can't use the PL/SQL in my scenario.
