• analyze the table & dbms_stats (chained lines)

  Hi guys,.
  
  Understand that dbms_stats collect statistics on (chained rows).
  To get chained lines, we can use one of the below:
  1. analyze the < table_name > table list chained rows;
  2 analyze the table < table_name > statistical calculation;
  
  the first lists the information chained rows in the CHAINED_ROWS table.
  the 2nd is best so that the information of chain_cnt are fulfilled in dba_tables. I can easily get the percentage of channel count by diviiding with the num_rows (for example if you need to list tables with 10 > string cnt percentage it would be easy).
  
  Right now, I'm leaving the need to collect statistics for night work by default oracle (who gather for table with variation in percentage of stale or > 10)... However, come together to string cnts.
  Can advise how can I get the string cnt without risking my existing services?
  
  And also will analyze statistics of table < table_name > estimate; replace my existing histograms?
  
  Thank you

• Automatic text of lines-placement of the table from one line to the other

  Hello

  can someone help me with a problem of formatting with tables;

  I would like to set up a table with multiple lines and the text automatically flow to the next line when you type once we're full... any help would be greatly appreciated

  Hey there,

  I just do the 1st rank.

  During the ENTIRE event, I changed the Javascript and insert the following code:

  xfa.host.setFocus(xfa.resolveNode("form1.#subform.Table1.Row3[1].Cell1"));
  

  Now it's working. You can do the rest.
  Tip: when coding, if you hold down Ctrl + Shift and click on any field, you get the name of the field instantly.

• Separating the sections of the table with black lines

  I am trying to add black lines to separate groups of cells in a table. I am using CSS, but know little things about it.
  
  The table is here: form
  
  And that's what I do: form.jpg
  
  Does anyone know how to go about it? I tried to add border-bottom-color in the CSS panel, but it applies the line to the top of the "total" fields
  
  Thanks, Dren.

• Update the table, exclude NULL lines...

  Hi all
  
  I have 2 tables.

  SRNO VARCHAR2 (10)
  FLAG VARCHAR2 (20)
  
  TABLE_B
  SNO VARCHAR2 (10)
  VARCHAR2 (20) IND
  
  I wan to update the INDICATOR in the IND of TABLE_B TABLE_A where SRNO both table games.
  
  Here I wrote
  UPDATE TABLE_A HAS
  SET A.FLAG = (SELECT B.IND FROM TABLE_B B WHERE B.SNO = A.SRNO)
  
  Here, the problem is, I don't want to update SRNO in TABLE_A where IND is set to null to TABLE_B. (or exclude the ONS of innerquery where IND is null)
  How can I change this query to do this?
  
  I tried to use
  UPDATE TABLE_A HAS
  SET A.FLAG = (SELECT B.IND FROM TABLE_B B WHERE B.SNO = A.SRNO AND B.IND IS NOT NULL)
  
  When I run this query, yet it updates all lines and updates to null FLAG where IND is set to null in the table B for SRNO even.

  Hello

  Try

  UPDATE TABLE_A A
  SET A.FLAG = (SELECT B.IND FROM TABLE_B B WHERE B.SNO = A.SRNO AND B.IND IS NOT NULL)
  WHERE EXISTS (SELECT B.IND FROM TABLE_B B WHERE B.SNO = A.SRNO AND B.IND IS NOT NULL)

• expand the table "static" or line

  I have a form in a format "table" with columns in subforms. One of the columns contains text fields that are set to develop to adapt because they are filled with text. Other subforms have simple text but with a color background. I want these to do, is extend according to the column of text expanding field, so the 'row' seems OK in all of the page. I also want the color backgrounds to expand.

  Not sure if this is possible (or if I make sense). Thanks for any help.

  Hello

  If you use the Table object, each cell would expand to match the row height automatically.

  If you are usign subforms, can you apply the color for filling of subform and not filling of individual objects?

  Otherwise, you will need a script to the output of each field event, making the height of the other fields in the subform the same height as the largest field. I thought I had a script, but can't find it at the moment.

• Created the form based on the table - created new line - how to retrieve line editing?

  Hello

  Sorry for such a stupid question, but being new in APEX, I don't know much about how the end user on a form.

  I have created a new form (not in a table), based on a table.

  I ran the form and created a new line.

  After the line was created, the form comes back ready to create another line (all the values in the fields).

  How can I go on the recovery of the line, I added just to make a few changes?

  Again, please forgive my ignorance.

• In a table not displaying the correct number of lines

  I have Apex 3.2.0.00.27. I have a tabular presentation over a simple table (update only). I'm trying to get the page to display more than 15 lines at a time. I think it does default to 10 when I created the page. I put "Number of Rows" to 100 in the report attributes, but only 15 lines are evidence. I played with all the parameters of paging and looked around at the other definition of report/region settings and can't seem to find out why he is not respect the value I set "Number of Rows".
  
  I had this same problem in point 2.2, as well and upgraded to 3.2 in the hope that he could have a bug (we do not have something superior to currently available in our dev environment 3.2).
  
  Is this a known limitation (I don't see it documented anywhere, but maybe I forgot) or I do something wrong? Is it possible that I can get a tabular presentation on top of the table, showing more lines?
  
  Thank you

  Hello

  "Number of Rows" value of 100 and check that you have nothing on 'Number of lines (element)' or 'number of maximum rows.
  Request disconnection then disconnecting from the constructor of the Apex.
  Back of connection and your form should show more lines

• Question from beginner on the fusion of the Recrords in the Table

  This question is about question 10-b of merger on page 3-41, it says:
  (page 3-41 "Oracle Database 10g SQL Fund. II Vol.1")
  
  Merge the data into the EMP_DATA table that is created in the lab last in the data in the table emp_hist. assume
  EMP_DATA external table data corresponds to the EMP_HIST of table, update the email column
  table EMP_HIST to match the row in the EMP_DATA table. If a row in the EMP_DATA table is not
  match, to be inserted in the tables of EMP_HIST lines are considered as corresponding whenever his first and
  family name are the same.
  
  For me, this issue is built wrong. First of all in the last lab we have not been asked to create EMP_DATA. Secondly, EMP_DATA is empty.
  Thirdly, this question asks us to merge into the table EMP_HIST while EMP_DATA is empty.
  
  Table EMP_HIST currently copied data from the employees table. Structure EMP_HIST:
  
  FIRST NAME VARCHAR2 (20)
  LAST_NAME NOT NULL VARCHAR2 (25)
  EMAIL NOT NULL VARCHAR2 (45)
  
  EMP_DATA table is empty. I created it as follows:
  
  create or replace directory emp_dir
  like 'F:\emp_dir ';
  
  drop table emp_data;
  
  CREATE TABLE emp_data
  (first name VARCHAR2 (20))
  , last_name VARCHAR2 (20)
  , email VARCHAR2 (30)

  FIELDS
  (first name POSITION (01:20) TANK)
  , last_name POSITION (22:41) TANK
  CHAR POSITION (43:72) by email)
  )
  LOCATION ('emp.dat'));
  
  Back to our question, I've done the merger as follows:
  
  merge into e emp_hist
  with the help of emp_data d
  on (e.first_name = d.first_name)
  When matched then
  game update
  Select = d.last_name,
  e.email = d.email
  When not matched then
  Insert values (d.first_name, d.last_name, d.email);
  
  I get this error:
  
  Error report:
  SQL error: ORA-29913: error in executing ODCIEXTTABLEOPEN legend

  29913 00000 - "error in the execution of %s legend".
  * Cause: The execution of the specified legend caused an error.
  * Action: Examine the error messages take appropriate measures.
  
  On the other hand, I said I'm going to try this:
  
  merge into emp_data d
  using e emp_hist
  on (d.first_name = e.first_name)
  When matched then
  game update
  d.last_name = select,
  d.email = e.email
  When not matched then
  Insert values (e.first_name, select, e.email);
  
  I get this error because the external table's final after its creation (no update, insert, delete authorized) as far as I know:
  
  Error report:
  SQL error: ORA-30657: operation not supported on external organized table
  30657.0000 - "operation not supported on external-organized table".
  * Cause: User attempted on the operation on an external table which is

  What happens if I want to import large data set in the external table?

  Hmm, external table is just a definition on how you want to watch a file as a table in the database. Think of it as a tool to import data.

  1. first of all, have a ready file (with data).

  2. create an external table using the format of the file.

  3. now you should be able to see the data when you do this. Select * from my_external_table.

  4. now, create an ordinary table where you want the data to insert permanently.

  5 insert into permanent_table select * from my_external_table.

  I hope this helps.

• The table of fixed size control: avoid behavior "scroll enter."

  I have a table control that will be always 6 rows of 8 columns.  I want to prevent the display of scroll that would display one or more empty lines at the end of the table.

  I tried to turn off 'Scrolling selection' in the menu contextual and disabling "vertical scroll bar see the" under properties - appearance.  However, even with these two parameters, if the user creates an entry in the last row and press the Enter key, the table scrolls a line and exposes an empty line at the bottom.

  Is it possible to remove this behavior?

  Return will scroll, enter will not, use a key event filter: http://forums.ni.com/t5/LabVIEW/Detecting-change-in-edit-position-of-a-table-control/m-p/1829131#M62...

• Transform the data in the column marked in lines

  I've already implemented Tom Kytes solution for dynamic / variant in the list that is found here and on his own works very well when passing a variable.  I'm trying to use it to decode several rows in a table.  Each row has a column of delimited data and I want to turn these data delimited by lines.

  Here is the configuration.

  create table data_source

  (upload_id number not null,

  data_source_id integer not null,

  sources varchar2 (50).

  ERROR_MESSAGE varchar2 (100)

  );

  insert into data_source (upload_id, data_source_id, sources) values (1, 1, 'a');

  insert into data_source (upload_id, data_source_id, sources) values (1,2, 'A:B:C:X');

  insert into data_source (upload_id, data_source_id, sources) values (1, 3, 'c');

  insert into data_source (upload_id, data_source_id, sources) values (1, 4, 'B');

  insert into data_source (upload_id, data_source_id, sources) values (1.5, 'Y');

  create the table data_source_lookup

  (varchar2 (10) sources non-null)

  ;

  insert into data_source_lookup (sources) values('A');

  insert into data_source_lookup (sources) values('B');

  insert into data_source_lookup (sources) values('C');

  My goal is to update the table data_source for lines where there is an invalid data source, in the example above that would be 2 and 5 lines.  I can do this individually using the in_list solution:

  Select * from table (in_list ('A:B:C:X',' :'))))

  If column_value not in (select data_source_lookup sources)

  Returns 'X' as expected.

  What I am struggling with is a method to make it through all the lines for a given loading ID:

  Update data_source

  ERROR_MESSAGE = "Source of data" is not a valid value

  where upload_id = 1 and...

  I tried to create a join cross- like this:

  Select ds.data_source_id, ds.sources, x.column_value

  DS data_source cross join (select column_value in the table (in_list (ds.sources,' :'))) x)))

  but as you can imagine passing in the function ds.sources has failed, returning "ORA-00904:"DS".» "SOURCES": invalid identifier.

  I'm sure I can solve this problem in a loop, but that seems inefficient.  Anyone know of a method by which I can pass the content of the column to the table function (in_list ()) for each line?

  For someone else it may call a function table in several lines, here's what I came with.  First of all, I changed my data to test a bit to add some very incorrect values.

  setting a day from sources set data_source = 'A:B:C:X:Y' where data_source_id = 1;

  This query will not return a list of lines that contain invalid values, including their wrong value:

  Select the rowid, sources, column_value

  de)

  Select the rowid, data_source sources)

  x cross table junction (utils.in_list (x.sources,' :'))))

  where column_value is not null

  and not exists (select null from data_source_lookup l where l.sources = column_value)

  AABk3MAAjAAAKd8AAA A:B:C:X:Y X

  AABk3MAAjAAAKd8AAA A:B:C:X:Y Y

  AABk3MAAjAAAKd8AAB A:B:C:X X

  AABk3MAAjAAAKd8AAE Y Y

  With this work, I can then modify cela a little bit to turn it back in a delimited list bad values that I can put in the error column.

  Update data_source x 2

  ERROR_MESSAGE = value

  (by selecting bad_value in)

  Select RID, "Invalid Data Source - ' |" listagg(column_value,':') within the Group (column_value control) bad_value

  de)

  Select the rowid RID, data_source sources)

  x cross table junction (utils.in_list (x.sources,' :'))))

  where column_value is not null

  and not exists (select null from data_source_lookup l where l.sources = column_value)

  (Group of RID) where rid = x 2 .rowid)

  where x 2 .upload_id = 1

  and x2.rowid in (select RID)

  de)

  Select the rowid RID, data_source sources)

  x cross table junction (utils.in_list (x.sources,' :'))))

  where column_value is not null

  and not exists (select null from data_source_lookup l where l.sources = column_value))

  ;

  It works well, and I find myself with:

  Error sources

  Source of invalid data in A:B:C:X:Y - x: y

  Invalid Data Source - X A:B:C:X

  C

  B

  Valid source of data Y - Y

• Rows in the table are break on separate pages...

  I have 20 lines equipped table:

  first 3 lines are on one page, then half of the page is empty hen remaining 17 rows is on the second page.

  How can I keep table to break the lines. I want all rows in the table to succeed himself.

  Help, please. Thank you.

  Keep them with parameters are in the table > Format > Format line...

  

  Note: the first row on the second page may also have a start parameter that indicates that it is at the top of a page or column.

  The control of widows and orphans just specifies how many rows to keep together (widow is the first page; ( orphan , is the second page) when a table has over a page. The higher the number, the more lines are forced to remain together.

• How to get the selected row in the table without SelectedRowKeys

  Greetings,

  I use JDeveloper 11.1.2.4.0 ADF application.

  and I have a few table containing only 1 and sometimes 2 rows. When the load table.

  by default, the first line is selected, and I can't call a selection listener (by selecting a line by calling

  a function). What I did (and it worked on the past, I don't know why now it doesn't) is:

  I removed the "SelectedRowKeys" property, so it will not automatically select 1st row loading,

  and on the events of selection, I use the code in this function:

  {} public void selectDisease (SelectionEvent selectionEvent)

  Object _selectedRowData = Disease_Table.getSelectedRowData (); the table select a line

  JUCtrlHierNodeBinding _nodeBinding = (JUCtrlHierNodeBinding) _selectedRowData;

  Line rw = _nodeBinding.getRow (); get the error here

  OperationBinding operation = bindings.getOperationBinding("ExecuteWithParams7");

  operation.getParamsMap () .put ("disease_id", rw.getAttribute("disease_id").toString ());

  Operation.Execute ();

  AdfFacesContext.getCurrentInstance () .addPartialTarget (panelTabbed);

  }

  I use the same method on the past on a different application on the same version of jdeveloper and it worked, I don't understand

  what I'm doing wrong here,

  Thanks for any help.

  I finally found the solution, since I do not use the property to a current line, I add programmatically:

  public static Object invokeEL (el String, class [] paramTypes, Object [] params) {}

  FacesContext facesContext = FacesContext.getCurrentInstance ();

  ELContext elContext = facesContext.getELContext ();

  ExpressionFactory expressionFactory = facesContext.getApplication () .getExpressionFactory ();

  MethodExpression exp = expressionFactory.createMethodExpression (elContext, el, Object.class, paramTypes);

  Return exp.invoke (elContext, params);

  }

  public static Object evaluateEL (String el) {}

  FacesContext facesContext = FacesContext.getCurrentInstance ();

  ELContext elContext = facesContext.getELContext ();

  ExpressionFactory expressionFactory = facesContext.getApplication () .getExpressionFactory ();

  ValueExpression exp = expressionFactory.createValueExpression (elContext, el, Object.class);

  Return exp.getValue (elContext);

  }

  {} public void rowSelected (SelectionEvent selectionEvent)

  invokeEL ("#{bindings.") MyVO.collectionModel.makeCurrent} «»

  new class [] {SelectionEvent.class},

  (New Object() {selectionEvent});

  Line = rw

  (Row), evaluateEL ("#{bindings.") MyVOIterator.currentRow}");

  rw.getAttribute("TheAttribueINeed").toString ()); etc...

  }

• addInstance does not work when the table has no rows

  I am trying to add a line to an empty table (no line) and it seems that addInstance does not work.

  table. Row. instanceManager.addInstance (1);

  Is there a different syntex if the table has no line?

  Thank you

  Try to use the shortcut to underscore for the instance Manager, it allows you to get items that do not yet exist.

  Then

  table.row.instanceManager.addInstance (1);

  becomes

  table._Row.addInstance (1);

• Total number of records in the table read

  Here is the procedure to read total no of record in the table specified by the user during execution. But it still gives the same answer for all the table. Can someone help me?
  
  create or replace procedure p3 (varchar2, not on the number tab)
  as
  Start
  Select count (*) from no tab;
  end;

  You need dynamic SQL statements.

  Or:

  To get the name of the Table and no lines

  Or simply use the data dictionary, collect statistics of the table, then:
  Select table_name, num_rows from user_tables;
