Group by returning multiple columns in a single request

Similar Questions

• 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...

• Merge multiple columns into a single column?

  Hello
  
  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.
  is it possible to run a query and the result will be extracted in a single column (multiple column values must be concatenated)?

• 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;

  You posted the SQL code. Not PL/SQL code.

  Group, but in the meantime, firstname and lastname.

  Of course, you will also need to group by firstname and lastname for this SQL query.

  With a Group of SQL, you have basically 2 types of values that can be returned:
  -the value of Group of
  -l' aggregated/calculated the value of this group

  If you could watch the first name and the last name by code:

  select
    code, MIN(firstname), MAX(lastname)
  from customer
  group by code
  

  You can see the number of unique name and surname by code:

  select
    code, COUNT(DISTINCT firstname), COUNT(DISTINCT lastname)
  from customer
  group by code
  

  Think of the clause group by in size (for example the code in the SQL above) and measures (calculations by code in the SQL above).

  I'm sure that the LISTAGG function should solve this problem, the problem is that I expected to find a solution on pure SQL or PL/SQL, perhaps with a nested Select statement.

  My version of Oracle's 10g Express Edition.

  LISTAGG is pure SQL, but it was introduced only in Oracle 11.2. All mentioned below should work in Oracle 10.

  The STRAGG from this page is very useful. You must copy and install approximately 60 line of PL/SQL code. Do it once, and then you can use hundreds of times in hundreds of motions, as if it were a built-in function. The main problem with STRAGG, it is difficult to get the output soprted. There is a modified version, designed for output sorted on this thread:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:15637744429336
  Never used. Can't vouch for it.

  SYS_CONNECT_BY_PATH seems to be the most popular way after the aggregation of the chain in Oracle 10. The example given on the page of the Oracle Base (that I posted in my last post) is a little clumsy and inefficient. See the next thread for a better example, using CONNECT_BY_ISLEAF:
  Re: Concatenate strings more lines in a single line.
  or, now that I see it, Pollywog example above.

• 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,

• Return multiple values from a function in a SELECT statement

  I hope I've provided enough information here. If not, let me know what I'm missing.
  
  I create a view that will combine the information from several tables. Most are pretty simple, but there are a couple of columns in the view that I need to get by running a function within a package. Even if this is quite simple (I have a function named action_date in a package called rp, for example, that I can use to return the date that I need through SOME rp.action_date (sequence_number).
  
  Here is the question: I really need to return several bits of information of the same record (not only action_date, but also action_office, action_value, etc.)-a join of the tables will work not here, as I will explain below. I can, of course, perform a function separate for each statement, but this is obviously inefficient. Within the select statement of the view, however, I don't know how each of the values that I need to get back.
  
  For example, right now, I have:
  
  Table 1:
  sequence_number NUMBER (10),
  name varchar (30),
  ...
  
  Table2:
  Table1_seq NUMBER (10),
  action_seq NUMBER (10),
  action_date DATE,
  action_office VARCHAR (3),
  action_value VARCHAR (60),
  ...
  
  I can't just simply join Table1 and Table2 because I have to perform processing in order to determine the rows returned matching, I really need to select. If the package opens a cursor and treats each line until it finds the one I need.
  
  The following works but is ineffective since all calls to the package returns the columns of the same record. I don't know how to put all the values that I need in the SELECT statement.
  CREATE VIEW all_this_stuff AS
  SELECT sequence_number, name,
  RP.action_date (sequence_number) action_date,
  RP.action_office (sequence_number) action_office,
  RP.action_value (sequence_number) action_value
  FROM table1
  
  Is there a way to return multiple values in my SELECT statement or I'm going about this all wrong?
  
  Any suggestions?
  
  Thank you very much!

  Hello

  What you want is a Query of Top - N , what you can do using the ROW_NUMBER analytic function in a subquery, like this:

  WITH     got_rnum     AS
  (
       SELECT     action_seq, action_dt, action_office, action_type, action_value
       ,     ROW_NUMBER () OVER ( ORDER BY  action_date
                                 ,            action_seq
                           ,            action_serial
                         ) AS rnum
       FROM     table2
       WHERE     action_code     = 'AB'
       AND     action_office     LIKE 'E'     -- Is this right?
  )
  SELECT     action_seq, action_dt, action_office, action_type, action_value
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  

  As written, this returns a single line (at most).
  I suspect you'll actually get a rank for each group , where a group is defined by a value in a table in which you join.
  In this case, add a PARTITION BY clause to the ROW_NUMBER function.
  If post you a small example of data (CREATE TABLE and INSERT statements), I could show you exactly how.
  As I don't have your tables, I'll show you the use of the tables in the scott schema.
  This is a view containing data in the scott.dept table and also to scott.emp, but only for the highest employee in each Department (in other words, the employee whose oldest hire date). If there be a tie for the first hire date, while the candidate with the lowest empno is selected.

  CREATE OR REPLACE VIEW     senior_emp
  AS
  WITH     got_rnum     AS
  (
       SELECT     d.deptno
       ,     d.dname
       ,     e.empno
       ,     e.ename
       ,     e.hiredate
       ,     ROW_NUMBER () OVER ( PARTITION BY  d.deptno
                                 ORDER BY          e.hiredate
                           ,                e.empno
                         ) AS rnum
       FROM     scott.dept     d
       JOIN     scott.emp     e     ON     d.deptno     = e.deptno
  )
  SELECT     deptno
  ,     dname
  ,     empno
  ,     ename
  ,     hiredate
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  
  SELECT     *
  FROM     senior_emp
  ;
  

  Output:

  Moreover, one of the conditions to the query you posted has been

  action_office     LIKE 'E'
  

  which equals

  action_office     = 'E'
  

  (AS is always equivalent to = if the string that follows AS does not contain the winning cards.)
  Did you mean say that or did you mean something like this:

  action_office     LIKE 'E%'
  

  Instead?

  Hello

  Here's another way.  It's like the solution in response #1, but it does not use a subquery:

  SELECT t.col1

  CASE

  WHEN COUNT (DISTINCT t2.col2) > 1

  THEN "Multiple."

  For ANOTHER MIN (t2.col2)

  END AS rnd_col

  T

  LEFT OUTER JOIN t2 ON t2.col1 = t.col1

  GROUP OF t.col1, t.col2, t.col3

  ORDER BY t.col1

  ;

  This assumes that in table t (col1, col2, col3) combination is unique.  If theat is not the case, change the GROUP BY clause, but you need to ensure that all lines of t becomes a separate group.

• HP Envy printer 4501: HP Envy 4501 scan multiple pages into a single document

  My HP Envy 4501 printer won't let me not scan multiple pages into a single pdf document.

  I already made sure the box 'Create a separate file for each scanned page' is unchecked under the section of the file in the advanced settings .

  After I scan the first page, I do not get a screen with a + (plus sign) which is supposed to allow you to scan additional pages in the same document.

  Is it possible that I can get a fix/update my HP Envy 4501 printer software which would show the screen with the + (plus sign) which allows to scan additional pages in the same document after the first page that you scanned?

  At this point, if I don't get this problem fixed soon, I'm about to return my HP Envy 4501 printer to the store I bought so I can get my money back and buy a printer from one of the competitors of HP before my store warranty runs out.

  I am very displeased with the printing software HP, support services and web presence that does not work half the time.

  Thank you

  Hello

  Lower the resolution of scan equal or lower to 300 DPI, scanning multiple pages is supported only on lower resolutions.

• Return multiple values at once of the listOfValues region

  Friends,
  
  I created a (listOfValues) region that has 4 fields/columns
  
  ResponsibilityName, ResponsibilityId, ApplicationName, ApplicationId
  
  I assigned a responsibility field ResponsibilityName of the listOfValues in a page.
  
  It works fine when I select a value in this LOV. It returns a value to the field of 'Responsibility' of the page.
  
  Is it possible to return the other 3 fields so while selecting ResponsibilityName in LOV. for example while you select a value for the field 'Responsibility', can the LOV return ResponsibilityId LOV to the 'ResponsibilityId' field in the page, at the same time?
  
  1 selection can return values 1 to the fields?

  You can return multiple values in the LOV. Simply create a result to the mapping of the array element Lov to the basic element of page. Once you select a value from the LOV, the element of basic page could get filled in with the value on the table of lov whereby it has been mapped.
