SQL count (*) with Group of

• Using the function count with grouped records

  Hi all
  
  This seems like it should be very easy, but I still have to find a simple way to do it.
  
  Suppose I want to count the possibilities which are grouped by Sales Rep at run time I filter this list with a parameter for sales stage and created date.
  I've simplified this greatly, but here's what my setup looks like now:
  
  Sales representative*-Count* _
  <? for-each-group: opportunity [SalesStage = param1 and creation > param2]; /SalesRep? >
  <? SalesRep? >-<? count (current - group (available))? >
  <? end for each group -? >
  _ Total
  
  The only solution I have to get my grand total so far is to create a variable and permanently keep a total that I will then display in the Total column. It all works, it seems that there should be an easier way, want to do a simple count (Id) for a total general. But given that the Total amount will appear after the end of each group-, I lose the filter that has been applied to the group so that the count is not valid.
  
  Ideas of the experts?
  Thank you!

  To get the total general
  use

  param2]/Id)?>
  

  Since you have not mentioned the complete xml code, I assumed, as the root.
  If this isn't the case, put the full path from the root.

  If you give some xml examples and explain the output you want, we can fix it immediately.

  go through these too... something can be drawn from here.

• Max, Min, and Count with Group By

  Hello

  I want the max, min and the meter of a table that is grouped by a column

  I need a combination of these two selects:

  select
       max(COUNTRY_S) MAXVALUE,
       min(COUNTRY_S) MINVALUE
  from
       tab_Country
  
  

  select
       count(*)

  The result should be a line with the maximum and minimum of the table value and the County grouped by table, not the max and min of each group! -J' hope you understand my question?

  Is this possible in a SQL-select?

  It is not clear what you want.  Maybe

  SELECT MAX (country_s) AS max_country_s

  MIN (country_s) AS min_country_s

  COUNT (DISTINCT country_txt) AS count_country_txt

  OF tab_country

  ;

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  You have a column named "COUNT" in your table? NOT! You probably intend to use the COUNT function: ditch the prefix aliases, functions use a prefix.
  >
  WHERE ACCESS_EFF_DATE > = 31 DECEMBER 12 '

  Don't use strings to DATE values. Use the dates and the TO_DATE function if you need to convert a string to a date literal.

  This Cartesian join between the tables is unlikely to be what you want to do.

  There are three different names in each of the departments. But in total, there are only 5 different.

  You can get the total that you want using analytical functions:

  SQL> select

    3  count(distinct e.job) cnt,
    4  sum(count(distinct e.job)) over () totalcnt
    5  from scott.emp e

          30          3          9
  

  But this gives you the total in a column, not a line.
  If you need as a line, you might be able to do something like this:

  SQL> select
    2  decode(grouping(s.deptno),1,'Total',s.deptno) dept,
    3  sum(s.cnt) cnt
    4  from (
    5     select
    6     e.deptno,
    7     count(distinct e.job) cnt
    8     from scott.emp e
    9     group by
   10     e.deptno
   11  ) s
   12  group by rollup(
   13  s.deptno
   14  )
   15  order by
   16  grouping(s.deptno),
   17  s.deptno
   18  ;
  
  DEPT                                            CNT

  30                                                3
  Total                                             9
  

  In the Interior, you select count (distinct but without rollup. Then an external selection where you do a sum for rollup your meter internal.

  Maybe an idea for you - maybe your solution two columns would work OK ;-)

• How Oracle performs with 'COUNT' when to go with "GROUP BY"?

  Hello

  I am aware that count return 0 there is still no data found a 'WHERE' clause

  However, when he goes with "GROUP BY", he goes to the "EXCEPTION block".

  declare

  a number: = 0;

  Start

  Select COUNT (1) in the doubles where 1 = 2

  Group 1;

  dbms_output.put_line ('a =' | a);

  exception

  While OTHERS then

  dbms_output.put_line ('Exception =' |) SQLERRM);

  end;

  /

  output:

  Exception = ORA-01403: no data found

  Why is Oracle jumps in the 'EXCEPTION' block when "GROUP BY" is added?

  Why may not behave in the same way as it did without "GROUP BY"?

  Please help me understand.

  Hello

  ...

  This is not true.  A query using COUNTY won't necessarily produce anything.  The query you posted is an example:

  Select COUNT (1) in DOUBLE where 1 = 2

  Group 1;

  does not 0; It produces nothing at all.

  Why is Oracle jumps in the 'EXCEPTION' block when "GROUP BY" is added?

  SELECT... INTO will trigger an error ("no data found" or "too many rows"), except if the query produces exactly 1 row.

  Why may not behave in the same way as it did without "GROUP BY"?

  GROUP BY means that the query will produce 1 row of output for each group (after the WHERE clause has been applied).

  A query using an aggregate (such as COUNT) without a GROUP BY clause function will always produce exactly 1 row.  (If you have a HAVING clause, then it can remove this row from the result set.)

  What you trying to do?

  Why do you use a GROUP BY clause in this case?  If you want a query which behaves as if it doesn't have a GROUP BY clause, then do not add a GROUP BY clause.

  This is not unusual. Another app could analyze for example hard the most often used SQLs in upstairs app - making benefit of further processing (in theory) of sweet analysis when you use these SQLs.

  In fact, I remember reading something to this effect as a performance for some factor or another Oracle document or note?

  So unless you have serious questions of shared pool, why bother with these sliders? What would be the problem?

• PL/SQL: Cursor with list filling can do IF EXISTS on Table

  Here's my problem. The DB I work with is a database of events (network events). I have a task to take a list of nodes of 2600 and see whether these nodes exist in a set of events that would be with a certain WHERE clause. On my first pass, I did WHERE AND NŒUD clause in (list of 2600 nodes). Well you can put only 1,000 items in a list so I've divided into 3 reports and served while a UNION all between them. This used 15% of the resources of the db and ran for hours and the Group dba like me to find a better way. They would prefer that I use PL/SQL.
  
  I am new to pl/sql (but not programming or SQL). So the first thing I've done is just figure out how to get my list in a Varray, which I then went to a table because I couldn't find examples, after hours and hours of searching the Web,.
  referencing a Varray with SQL syntax.
  
  START CODE sample 1 *.
  DECLARE
  DECLARE
  TYPE NodeList IS TABLE OF VARCHAR2 (255);
  Node NodeList: = NodeList ('node1', node2', [.. .list of 2597 nodes..], 'node2600')
  
  BEGIN
  dbms_output. Enable (1000000);
  FOR i IN Nodes.FIRST... Nodes.LAST
  LOOP
  DBMS_OUTPUT. Put_line (' relevant points: ' |) Nodes (i));
  END LOOP;
  END
  END CODE Sample 1 *.
  
  The pseudo-code I'm envisioning goes something like this:
  
  IF one of these nodes (nodes of 2600 list),
  There are in the nodes for this WHERE clause (which is taken from the event db table).
  then print the records (of the events in the event db table) that contains the nodes (ie the list nodes).
  
  I think I found an example with 2 sliders, but I can't find this example once again. And anyway, I can't figure out how to get my list in a cursor. I have many examples of how to complete a cursor on a select statement against a database.
  
  I tried this but it did not work:
  START the CODE sample 2 *.
  DECLARE
  DECLARE
  TYPE NodeList IS TABLE OF VARCHAR2 (255);
  Node NodeList: = NodeList ('node1', node2', [.. .list of 2597 nodes..], 'node2600')
  
  CURSOR MOM_OVO_NODES IS
  SELECT the node
  OF NodeList
  ORDER BY node;
  
  BEGIN
  dbms_output. Enable (1000000);
  
  FOR nodelist_rec IN MOM_OVO_NODES
  LOOP
  dbms_output.put_line (' relevant nodes: ' | nodelist_rec.) Node);
  END LOOP;
  
  END
  END CODE sample 2 *.
  
  Is there a way to get this list in a slider? Or I think about this correctly?

  PL/SQL is probably going to be a slower solution, then SQL. It's almost always.

  Your best bet would be to maintain a table of nodes. You can then use a single SQL query with an IN WHERE clause as:

  WHERE node in (SELECT node FROM node_table)
  

  Or you can use a join (the method preferred honestly, gives Oracle more optimization options).

  If you don't want to maintain a table of node, you can always create a global temporary Table or the external Table that could be loaded prior to running your report.

  If you have tried these methods, and it is still too low or high intensity of resources, then we should look at the SQL and chorus only. See the PL/SQL FAQ's for more information on setting the SQL statements.

• Count (*) with the nested query

  Hello
  I have a question about the count (*) with the nested query.
  
  I have a table T1 with these columns:
  Number of C1
  Number of C2
  Number of C3
  Number of C4
  Number of C5
  
  (The type of each column is not relevant for example).
  
  This query:
  Select C1, C2, C3, C4
  from T1
  Group C1, C2
  
  It is not correct becausa C3 and C4 are the columns specified in the GROUP BY expression.
  
  If you run this query:
  Select count (*)
  (select C1, C2, C3, C4
  from T1
  Group C1, C2)
  
  I don't have an error message (properly, the result is the number of records).
  
  Why?
  
  Thank you.

  ErrChk DAQmxCfgImplicitTiming(hCnt1, DAQmx_Val_ContSamps, 2);

  ErrChk DAQmxStartTask (hCnt1);

  When I run it, I get an error-50103 "the resource specified is reserved". If I change the FiniteSamps to ContSamps on the first counter, everything works fine.

  If I use only one counter with FiniteSamps, everything works very well.

  Is this a bug in DAQmx or the use of double counter on M Series devices is limited to ContSamps?

  Hey Vic,

  It is actually planned on a device of the M series.  Here's a time diagram of the M Series user manual which might make this a little clearer:

  

  The device uses actually one counter for the other door so the result is a generation of finite pulse.  If you can provide the door from another source, you can configure a generation of continuous pulses on two counters and their door (DAQmx calls it a "relaxing break") of this external signal.

  You can also look at the use of the digital I/o correlated to generate impulses over multiple (up to 32 lines on your 6229 and 6259).  You could use one of the counters to generate a time base for digital lines and build the waveform as a result.

  One thing to note is that our new X series cards can generate a generation of impulses finished on a "single" counter (it was actually a paired internal counter that allows this).  There are four accessible counters by the user on the X series devices, which means you could generate four pulse trains finished.

  Best regards

• How to build a single Point (On-Demand) edge counting with relaxing break

  Hi, I am building a clock as shown below. It is also called 'Single Point (On-Demand) Edge Counting with relaxing break'.

  "

  I have problem to find the code example. So far, I can only build a counter edge without a controller trigger like below. Could someone help me?

  

  
  

• Internet Explorer 8 XP configuration with group policy

  I'm trying to update the zone information of IE8 via the group policy on the xp computers.  I don't get any errors, but the parameters are not get applied to the computers in the ORGANIZATIONAL unit.  I created a test organizational unit placed a few inside computers and created a group policy I linked to the test OU.  I blocked the legacy on the OU.  Gpresult displays that it is the only political hitting the computer.  Some Internet Explorer settings are updated while others are not?  I imported the inetres.adm file in the new policy.  I use a server of w2k8 Windows with Group Policy Management to update the policy and run gpresult.

  For customers it does not implement try to use the GPupdate command in these machines. Also, you try to apply a restart on these machines and may also attempt to refrech domain and Active Directory.
