Multiple queries in a single request

• Group by returning multiple columns in a single request

  Hello
  
  Sorry to ask this simple question, I suppose, but here's my problem.
  
  I am building a query to get to say the smallest user_id of workers in society by Department.
  
  The query goes like:
  
  Select emp... Department,
  min (EMP.user_id)
  employee emp
  Emp.department group
  
  It gives me the smallest user by Department id, which is what I want. But how can I also get the name of this person?
  
  I know that the condition of 'min' distinguishes a single record (there are no two people with the same user_id in the Department).
  But how can I also get the name without turning the query above in a subquery that I would like to once again a link to the table of employees?
  
  I know that the following works, but I don't think it's the best option:
  
  Select v1.department,
  v1.user_id,
  Emp1.name
  employee emp1.
  (select emp... Department,
  min (EMP.user_id)
  employee emp
  Group emp.department) v1
  where emp1.user_id = v1.user_id
  
  
  This is just one example of data. This is the principle which I don't understand.
  
  Any advice would be much appreciated.

  Hi, Cyril.

  To find the name of the person who has the lowest user_id

  SELECT    department
  ,         MIN (user_id)   AS lowest_user_id
  ,         MIN (name) KEEP (DENSE_RANK FIRST ORDER BY user_id)  AS person_with_lowest_user_id
  FROM      emp
  GROUP BY  department;
  

  'MIN (name)' above means that if there is a link for the lowest user_id, you will choose the candidate with the first name.

  If you want to display several columns in the row with the lowest user_id, you must have an expression of 'KEEP (DENSE_RANK...)' separate for each column. In this case, you will find may be easier to use the RANK or the analytical ROW_NUMBER in a subquery, like this:

  WITH  sub_query  AS
  (
       SELECT  department
       ,     user_id
       ,     name
       ,     col2, col3, col4, col5
       ,     RANK () OVER ( PARTITION BY  department
                             ORDER BY          user_id
                      )  AS r_num
       FROM     emp
  )
  SELECT     *     -- or list all columns EXCEPT r_num
  FROM     sub_query
  WHERE     r_num = 1;
  

• 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,

  ;

• Break with multiple queries

  I built a relationship with the data model and two requests. I set up the break-up on it. The two queries contain the Department and select it. The Department is the key to the outbreak. The breakdown by item in the bursting may be alone. So if I specify, for the split by element the Department in the first query, only the first request is divided by Department, but the second query is not distributed. Breaking for queries longer divide? How to divide multiple queries in the logic of failure?
  
  Can you help me please?

• scripts / block of multiple queries in a query from CF in Oracle

  Greetings:
  
  I am above all a MS SQL programmer and I wonder how to execute multiple statements within a block request unique cfquery. For example, on MS SQL, I can do multiple delete queries, or update and select a block of cfquery, but I get an error when I try to do this on ORACLE. Is there a way to do this on ORACLE?
  
  Thank you!

  Your best bet is to use multiple CFQUERY CFTRANSACTION tags tags if you want them to all be handled in a "block" or "session". Or, put all your SQL queries in a PL/SQL stored procedure.

• 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)?
  
  Thank you

• HP Deskjet 2540: Cannot scan multiple pages into a single PDF for printer Deskjet 2540 Windows 10

  I'm scanning several pages (5) in a single document.  I followed the instructions in the other answers to the questions - I chose the type of pdf file, I chose a less than 300 DPI resolution (I use the default value of 200 dpi), and I clicked on Preview (and not scan).  However, there was no option 'Add' page when you preview is posted.

  

  I don't know that I've scanned multiple pages in a single document, following the intructions of same, before moving on to Windows 10.  It is no longer possible with Windows 10?

  Thank you.

  Is this program, the program of HP that was loaded with the drivers and full software?

• Track of multiple graphs on a single diagram of waveform with dynamic data types

  I'm putting multiple charts on a single diagram of waveform and data contract error. I was wondering if it has something to do with the fact that the dynamic data is used (I have had no problem with other types of data in the past). Does anyone know how to fix this? I have attached the following .VI. There will be a lot of. Live on the bottom which does not load, but they are not related to this problem.

  Thank you!

  I don't know what you're doing now, but a part of your origianl code is simply ridiculous. Your DAQ assistant takes a single point. You convert that into an array. If you had converted into a scalar value (which is) first place, your graphics update would have been fine.

  If you want to remove the DAQ Assistant, and then select generate DAQmx code. You'll be a little more closely, but it seems that it generates a NChan DAQmx Read 1Samp instead of a 1Chan 1Samp DAQmx read.

• scanning multiple pages to the single PDF using HP ENVY 4500

  The guide says scan of the computer (as opposed to scanning from printer).  I do that and still can't scan multiple pages into a single PDF file.  Is it still possible?

  Hi griff0530,

  I understand that you want to scan multipage documents into a single .pdf file using your HP Envy 4500, yes it is quite possible.  When you use the HP software on your computer, follow the steps below:

  1. loading the document.

  2. click on scan . An overview of the analysis is displayed (by default).

  Important : the Preview Scan function must be enabled for scan multiple pages into one file documents. Additional pages from the original are added for the single file in the Scan preview window.

  3. in the scan preview is displayed, do one of the following actions:

  Click the sign Plus () on the left side of the window to scan additional pages. If you do not use an ADF, you must load the next page of the document on the glass of the scanner to add to each additional page.

  4. click on Save to capture the scanned file, but leave open the HP Scan.

  5. click on done to capture the scanned file and close HP Scan.

  I found this great information here: how Scan: Windows 7

  If you are using any other operating system, it's ok the same steps apply. I hope that's what need you!

  Thank you

  I'm trying to scan multiple pages into a single document.  I use an all-in-one HP Envy 4501 and 8.1 of Windows running.  I used to be able to do this at some point, but for some reason, lately I'm not able to.  I read the other posts that spoke of a sign "+" on the left side of the screen, but it isn't there for me.  Also, I can not just save the page and scan the other without having to save them in different files.  Please notify.

  The HP software click on scan a Document or Photo and make sure that Scan to sow preview is checked.
