• How do I rotate my result of a query from a line to a SQL column?

  Hey, guys:
  
  Is it possible that I can rotate my result of a query from a line to a SQL column?
  
  It's a certain type of pivot example
  Instead of
  DEPTNO DNAME
  -------- ---------------
  10 accounting
  It would be
  DEPTNO: 10
  DNOM: ACCOUNTING

  Hello

  When you have N columns to rank 1 and you want to display in the form of 1 column on several lines, it's called Unpivoting . Here's a way to do it:

  WITH     cntr     AS
  (
       SELECT     LEVEL     AS n
       FROM     dual
       CONNECT BY     LEVEL <= 2     -- number of columns to be unpivoted
  )
  SELECT     CASE c.n
           WHEN  1  THEN  'DEPTNO'
           WHEN  2  THEN  'DNAME'
       END || ':'        AS label
  ,     CASE c.n
           WHEN  1  THEN  TO_CHAR (d.deptno)
           WHEN  2  THEN  d.dname
       END || ':'        AS val
  ,     d.deptno               -- PK, if needed
  FROM         cntr        c
  CROSS JOIN  scott.dept  d
  WHERE   deptno = 10               -- or whatever
  ;
  

  The query above works in Oracle 9.1 or more.
  From Oracle 11.1, you can also use the SELECT... Function of the UNPIVOT operator.

• How to remove the name of the column in the select clause

  Hello guys,.
  
  I want to just delete a column name in the select clause. Because I don't want to write all the names of columns. I hope I am.
  
  In other words, I want the following.
  

  Select   * - unwanted_column  from table;
  
  instead of this 
  
  Select col1, col2, col3, col4, ........ col 10000 from table;

  Hello

  There is nothing in SQL, which means "all columns * except *...» ». As others have said, the only way to achieve these results in SQL is to list all the columns you want.

  Your front end may have a feature that allows you to hide a specific column. For example, in SQL * Plus, you can use COLUMN... NOPRINT , like this:

  COLUMN      dname     NOPRINT
  
  SELECT       *
  FROM       scott.dept
  ORDER BY  dname
  ;
  

  Output:

  `   DEPTNO LOC
  ---------- -------------
          10 NEW YORK
          40 BOSTON
          20 DALLAS
          30 CHICAGO
  

  There is a column called dname in the scott.dept table; the query above uses actually. But, because of the order of the COLUMN, SQL * Plus will not display this column.

  You can create a custom procedure to generate data in csv format and print to the browser.

• Select the anchor point of the Group and anchor it to the PointInsertion

  Hi all

  How to select the anchor point of the Group and dock it at the point of insertion of the document in indesign cs5.5 using javascript or vb.net

  You need get a reference to your group - call the myGroup - and the other to the PointInsertion where you want it anchored - call - the myIP. Given those, you can achieve your goal (in CS5 or later) by:

  myGroup.anchoredObjectSettings.insertAnchoredObject (myIP);

  You can specify a second parameter, if you want that specifies the position of anchor:

  myGroup.anchoredObjectSettings.insertAnchoredObject (myIP, AnchorPosition.anchored);

  That should help you get started.

• Need help with PL/SQL so and then select

  Hello guys, I am new to the PL/SQl programming (only Java experience) and I'm pretty stuck to my task. It would be great if you could help me. I am in programming with Oracle SQL * Plus Version 10.2.0.3.0

  Whenever a user logs on to the server a database entry is created with information about the logged-on user. I need to create a PL/SQL command that selects all the information from last month. Unfortunately, the date_stamp column has a certain weird format: 1131210 for December 10, 2013

  
  

  My idea so far:
  

  
  

  DECLARE

  v_today NUMBER;

  BEGIN

  v_today: = TO_NUMBER (TO_CHAR (SYSDATE, 'MM'));       -Save the number of the month (e.g.12) in v_today

  IF v_today = 01 THEN

  SELECT * from audittrl

  WHERE the date_stamp between 1131201 AND the 1131231;

  ELSIF v_today = 02 THEN

  SELECT * from audittrl

  WHERE the date_stamp between the 1130131 AND 1130101;

  .......

  END IF;

  END;

  /

  Error code: "an INTO clause in this SELECT statement.

  I do not want to save the result to select a variable, hope you can help me. Thanks in advance.

  Thanks, I'll try that, if still get caught once, I'll be back. Anway I'm not sure of the solution of Chris227, because I can't test it right now. From my point of view it gives you information the current month (e.g., December) and not the month previous (-online November), or have I missed something. ?

  You are right.  In addition, it does not for a given year.  If you have data from several years in the table, it will select lines for the month of December 2012, 2011, 2010,... but also of 2013.

  Here's a way to get around that:

  DECLARE

  prev_month_start PLS_INTEGER: = TO_NUMBER (TO_CHAR (ADD_MONTHS (SYSDATE-1)

  , "YYMM"1' "01"

  )

  );

  this_month_start PLS_INTEGER: = TO_NUMBER (TO_CHAR (SYSDATE

  , "YYMM"1' "01"

  )

  );

  BEGIN
  FOR (IN) rec
  SELECT *.
  Of audittrl
  WHERE the date_stamp > = prev_month_start
  AND date_stamp< >
  ORDER BY user_id, date_stamp - or other

  )
  LOOP
  dbms_output.put_line (rec.date_stamp);
  dbms_output.put_line (rec.event);
  dbms_output.put_line (rec.user_id)
  dbms_output.put_line (rec.host_name);
  END LOOP;
  END;

  This should also be more effective, because it will allow the optimizer to use an index on date_stamp.  Even if there is no index, it will be more effective because it avoids calling any function (for example, SUBSTR) on each line of the table.

  You needn't PL/SQL to get these results.  Just use SQL, you might say:

  SELECT event, host_name, user_id and date_stamp
  Of audittrl
  WHERE the date_stamp > = TO_NUMBER (TO_CHAR (ADD_MONTHS (SYSDATE-1)
  , "YYMM"1' "01"
  )
  )
  AND date_stamp<  to_number="" (="" to_char="" (="" sysdate="" to_number="" (="" to_char="" (="">

  
  , "YYMM"1' "01"
  )
  )

  ORDER BY user_id, date_stamp - or other

  ;

  Your front end will provide column headers and touch the data so that the columns line up.  It can also set the output to a file.  (For example, if your front-end is SQL * Plus, you can use the command of the COIL.)

  I guess date_stamp is a NUMBER.  If it is a string, the solutions above can be simplified a bit.

  This problem (and many other problems) would be so much simpler if date_stamp was a DATE column.  Using numbers or strings to store the date information is simply asking for trouble.

  Thank you

  Abhijit

  Abhijit,

  Now that you have already re-created the table, it would be difficult to find the exact cause. But I suspect it could happen due to the creation of table in a way not recommended the use of quotes.

  If you use double quotes while creating the table/column names, you must always use capital letters. Better is not not to use quotes in all. Here is an example of a test that could be the cause of your error.

  SQL > drop table test;

  Deleted table.

  SQL > create table test ("col1" nvarchar2 (200), col2 varchar2 (200));

  Table created.

  SQL > select Col1 from test;

  Select Col1 from test

  *

  ERROR on line 1:

  ORA-00904: "COL1": invalid identifier - it is him you got. Even if there is col1 column in the table, but I'm unable to select due to the bad way to appoint.

  SQL > drop table test;

  Deleted table.

  SQL > create table test ("COL1" nvarchar2 (200), col2 varchar2 (200));

  Table created.

  SQL >

  SQL > select col1 from test;

  no selected line

  The test case above apply to the tables as well.

  In general, Yes, if the function is a function table, you can do something like:

  select  t.col1,
          t.col2,
          f.col1,
          f.col2,

• Calculation of layer of sql column

  V: 10.2.0.3
  
  I want to calculate column-layer of a sql query:
  

  select a "column1", "column1" + 1
  from ...

  but it does not work...
  Anyone know how?

  Hello

  If the function is declared as DETERMINISTIC, then it could be called only once, although you have coded the two calls.

  In general, you can call the function and give the result one alias, in a subquery. Then, in a super-requete, you can use this alias anywhere and as often as you want
  for example:

  WITH     got_column1     AS
  (
      SELECT  a (1, 2)      AS column1
      ,         ...
      FROM    actual_table
      ...
  )
  SELECT  column1
  ,     column1 + 1     AS column2
  ...
  FROM     got_column1

  In addition there are errors in your code and it won't work, it is unclear what exactly you want as you have not explained with sample data and expected results.

  You select the number of columns to collect your in bulk.
  You collect the commission for an entire Department without regard to the employee for each employee record, so you would end up duplicating your data in your pl/sql collection (don't call them paintings, they are not really tables).
  You have not initialized l_num_index1 so it will never be incremented
  You have added an unnecessary error handler.
  etc.

  I'm guessing that you are looking for something in this direction...

  declare
    type EmpTabType2 is table of emp_commision%ROWTYPE index by binary_integer;
    emp_tab2 EmpTabType2;
  begin
    select ec.*
    bulk collect into emp_tab2

  Well, I still have no idea why you are wanting to use dynamic SQL statements for this (it will only add a memory load, especially if your routine is frequently called) but I have at least understood your problem.

  The first anonymous block shows using the static SQL, the second shows how to use dynamic (and you reference a declared local variable, where your problem is).

• Generate CSV with pl.sql column names

  Hi guys,.
  
  Well, I am back after a long hiatus in this form, was occupied by SAP BI project.
  
  Now do some oralce - sap project, well here, I needed to generate a CSV of many many queries,
  
  I can do via sql, but I tot it would be better to write a package or a common procedure to generate csv files
  
  ex, if I pass the query to the proceudre it should generate csv on the server directory file, later I send these file to the users concerned.
  
  The e-mail part is later, but first of all is to have a package of generic to launch and run the query n generate the csv file.
  
  I guess this should be possible using native dynamic sql and utl_ package, but I don't know how to get the columns name,
  
  If one has implemented this please explain me the way,.
  
  ex:
  

  Select emp,mgr, empno from emp;
  
  emp mgr empno
   1    1    123
    2   1    234
  
  something like that
  hope my question is clear 

  Maybe try this
