  Best thing you can do is to start a new thread.
  This is after you have completed :
  -Documentation

  and found nothing.
  Do not start new threads that are FAQ...

  Adding questions to existing threads is called 'diversion' a thread and is not appreciated. Especially when you're digging up old threads.

• Quotes in a column alias

  Possible to have double-quotes in a column alias in a projection of SQL? Long story involving Apex, Anychart v5 and how Apex appoints series of data in the XML generated for several Y axis.
  
  This problem can be solved easily if I can add a quotation mark in a column alias. For example

  select
    some_col as "COL1"" param1=123"
  from dual

  No comment on the Apex by using column labels to generate XML tag name values... {noformat} ;-) {noformat}
  
  Of course, the SQL parser like quite the format above.
  
  Had a look at the SQL reference guide and it does not say much in this regard. It seems that there is no work around - correct?

  Column alias is also to respect the rules of naming of object databases? :

  »
  ...
  7 nonquoted identifiers can contain only your database character set alphanumeric characters and the underscore (_), dollar sign ($) and sign pound (#). Database links can also contain periods (.) and 'at' sign (@).
  Oracle strongly advise to use $ and # in nonquoted identifiers.

  Quoted identifiers can contain any characters and punctuation marks and spaces.
  However, or quoted or nonquoted identifiers can contain double quotes or the null (\0) character.

• MySQL - Alias Question

  Hi Chaps,
  
  Have a fast for you...
  
  I know that in a SQL query, you can create an alias for column name, for example.
  

  ...tbl_jobxml.job1 as job2

  
  but you can create an alias for the value contained in this column, for example.
  

  ...tbl_jobxml.job1='y' as job2='Complete'

  
  Sorry if this is a stupid question, but it is better to ask than claim ignorance!
  
  ????

  I don't think it will work, as you say the query to find the 'y' in the field.

  If the field has contributed to 'y' as a value, it will work fine.

  But I don't think that an alias will work on value.

  I use oracle 11.2.0. I'm trying to get a report of repairs, so I put a condition if:
  3. WHERE RETURNED > 1; - then it will only show the repair costs

  I got an error after exec report_cursor

  SQL > exec report_cursor;

  ERROR on line 1:
  ORA-06550: line 1, column 7:
  PLS-00201: identifier 'REPORT_CURSOR' must be declared.
  ORA-06550: line 1, column 7:
  PL/SQL: Statement ignored

  ---------PL/PSQL-----------------------------

  The line above shows what is simply boredom!
  What follows is not just the PL/SQL code. Like many scripts, it's a mixture of SQL * more and PL/SQL (and, unwittingly, pure SQL, too).
  'SET SERVEROUTPUT ON' is a SQL * Plus command. Like all SQL * most orders, be completed before the end of the line. In this case, it means "DECLARE CURSOR report_cursor IS" is taken as part of the SET command. When I run it, I get a SQL * Plus error message "SP2-0158: unknown SET"declare"option

  SQL >
  1 set serveroutput on DECLARE CURSOR report_cursor IS

  If the first line is ignored. Since you have not started a block PL/SQL, lines 2 and 3 are considered as being a pure SQL query.

  2. SELECT INVID REFERRED, INVOICEDA, REPAIRDETAIL OF THE INVOICE
  3. WHERE RETURNED > 1;
  4 I_INVID INVOICE. INVID % TYPE;
  5 I_REPAIRFEE INVOICE. SENT % TYPE;
  6 I_DATE INVOICE. TYPE % INVOICEDA;
  7 I_DETAIL INVOICE. TYPE % REPAIRDETAIL;

  I know not why the lines 4-7 do not cause any errors, because the DECLARE has been ignored.
  From line 8, the script is interpreted as PL/SQL: it looks like an anonymous block that does not have the optional DECLARE section.

  BEGIN 8
  9 DBMS_OUTPUT. Put_line ('ID, cost and Scooter fixed Details'); ...

  Please formatting your code. It will help you as well as others.

  All you have to do is to start the DECLARE statement on a charge line:

  set serveroutput on 
  
  DECLARE
      CURSOR report_cursor IS
              SELECT  INVID

  The datatypes/names/sizes and the number of columns in a query is called the 'projection' and is determined at the time of the analysis. This is why he cannot be determined by data without using 2 passes data (to determine what should look like the projection and a dynamic to query the data again with that dynamically generated projection).

  What you're trying to do is basically abuses the SQL engine and it's really something that is the best reporting tools that data from the request and then treat for formatting the output based on the data itself.

  You have me working for the kuddos

  OK, in this case fixed the objective to the shape that you did earlier.

  In the name field, create an element in the page on this page (or change the properties of the current which generates the error) and the properties of the item to:

  Source: Source Type: PL/SQL Expression

  Source: Source of value or Expression:

  : P9_INDSNAME | : P9_INDFNAME

  or an expression of function/pl-sql like this.

  Make sure that P9_INDSNAME and P9_INDFNAME exist on this form and are normal database fields (which can be hidden if you don't show them)

  OK maybe I interpreted in the wrong sense :))

  Can you help with this problem.

  I have an EMP table with more than 10,000 rows and 500 columns.

  The developer was asked to edit a column ATTRIBUTE1 of VARCHAR2 (10) number;

  It is said that the column must be empty to change the data type, so I created a backup:

  CREATE TABLE EMP_BAK AS SELECT * FROM EMP;
  TRUNCATE TABLE EMP;
  ALTER TABLE EMP MODIFY (ATTRIBUTE1 NUMBER);

  How can I insert it using the... INSERT INTO EMP SELECT * FROM EMP_BAK;

  To aggraviate the situation the designer wants to move the position of the column in the 100th place in 10th place.
  Assuming that you can't reason with out them, how to make this task easier?

  Thank you

  Rather than create a new table and your complications mentioned above, you can follow the Sub method I guess.

  ALTER TABLE DUMMY_ATTRIBUTE1 ADD EMP NUMBER;

  UPDATE EMP
  ATTRIBUTE1 SET = DUMMY_ATTRIBUTE1
  WHERE 1 = 1;

  COMMIT;

  UPDATE EMP
  ATTRIBUTE1 SET = NULL
  WHERE 1 = 1;

  COMMIT;

  ALTER TABLE EMP CHANGE ATTRIBUTE1 NUMBER;

  UPDATE EMP
  SET DUMMY_ATTRIBUTE1 = ATTRIBUTE1
  WHERE 1 = 1;

  COMMIT;

  ALTER TABLE DROP COLUMN DUMMY_ATTRIBUTE1 EMP;

• Stacked column linking question

  APEX 4.0
  Anychart 5
  
  
  Setting SQL shaped for a stacked column or a bar chart is pretty simple.
  
  SELECT
  link,
  label,
  Value1,
  [value2],
  [value3,]...
  Of...
  
  
  This will allow your entire column/bar become a link.
  
  Is there a way to allow each value in a column/bar to post a link to another location?
  
  For example -.
  In view of the data set:
  
  Label: balls football: baseballs: Tennisballs
  East: 100:30:20
  West: 40:50:60
  North: 50:50:50
  
  A stacked bar will create three bars, each with three regions. If a link was specified according to the format described above, each region in the East bar link to the same place. Ditto for the bars of the West and the North. However, I have a 9 different links for this data set. Is this possible?
  
  Austin

  Hi Austin,.

  Yes, it is possible to define a different link to each item in your series on the chart. It goes down just in the way you write the query in the chart series. You can use a CASE statement to define a different link according to the value of the LABEL of your query, or you could make a UNION of several statements, with a different link defined in each select statement. Using your example data set, I've implemented the following example on my sample application - http://apex.oracle.com/pls/apex/f?p=36648:59 - and I have stressed the three queries used to generate the graph. The query of the 1 series uses a CASE statement, and other queries of two series are a UNION of several select statements. Is looking to achieve?

  I hope this helps.

• DataGrid width column resize question

  Is it possible to implement a DataGrid with absolute width columns AND columns of relative width?
  
  I have a datagrid that resizes with the browser window and widths of columns can be resized by the user, but the itemRenderer buttons still have to do the same width(resizable='false').
  
  I tried different combinations to attack this problem manually resize the columns in the resize event DataGrid, binding the function column widths, but nothing seems to work well.
  
  any tips/suggestions/ideas out there?
  
  I can post some samples of failed attempts if requested.

  OK, try this. It's 'force-TI-in-la submission' programming and isn't usually my style, but good, the other stuff apparently do not work.

• join column Muti question

  We recently had a problem where we ran out of process on a single instance of the cluster so I will try to ask the DBA_HIST_ACTIVE_SESS_HISTORY to see which application has most of the sessions connected at the time.  After much research, I came with a view online but I can't figure out how to get the join condition to match the session ID and the session_serial # as a whole rather than individually.

  So if I run this query:

  Select distinct session_id, session_serial #.

  of DBA_HIST_ACTIVE_SESS_HISTORY

  where sample_time between to_date (28 Aug 14 12:01:00 am "," DD-MON-YY hh: mi: ss pm') and to_date (28 Aug 14 12:32:00 am ',' DD-MON-YY hh: mi: ss pm')

  and user_id! = 0

  and instance_number = 1;

  He returned 1507 lines.  That looks all right as a process parameter is set to 2000, when he made a mistake on.

  But when I try to get the number of session and group by user_id, charges are way off:

  Select e.user_id, count count (user_id)

  Join e DBA_HIST_ACTIVE_SESS_HISTORY

  (select distinct session_id, session_serial #)

  of DBA_HIST_ACTIVE_SESS_HISTORY

  where sample_time between to_date (28 Aug 14 12:01:00 am "," DD-MON-YY hh: mi: ss pm') and to_date (28 Aug 14 12:32:00 am ',' DD-MON-YY hh: mi: ss pm')

  and user_id! = 0

  and instance_number = 1) all_sess

  on e.session_id = all_sess.session_id

  and e.session_serial #= all_sess.session_serial #.

  E.user_id group;

  USER_ID COUNTY

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

  30                     6

  494 16921

  479 147385

  486 779

  490                    48

  I think that if I can get the join to match somehow the session_id and session_serial # together as a pair rather than compare each session_id and session_serial # separately, it might work.  Any help would be appreciated.

  I think it is because you are trying to reach the subquery for the entire table, not only the rows in the specified period.

  2. (select user_id, session_id, session_serial #)
  3. of dba_hist_active_sess_history
  4. where sample_time between to_date (28 Aug 14 12:01:00 am "," DD-MON-YY hh: mi: ss pm') and to_date (28 Aug 14 12:32:00 am ',' DD-MON-YY hh: mi: ss pm')

  You list a version if this solution works under at least 10.2.0.3 and superior. You must use evalname(). I know it does not work sur.1 and I'm not sure what maniere.2 looks.

  declare
