• best way to take a trace of a session

  Hello
  
  I always use dbms_system.set_ev (sid, serial #, trace_level...)
  
  What is the best way to take a trace of a session?
  There are other ways to run a trace of a session?
  
  See you soon,.
  
  EA

  Hello

  Here are a few ways to generate a trace:

  To activate the traces at the instance level

  (1) assign the parameter sql_trace the pfile or spfile. It will allow to trace for all sessions and the background
  process

  SQL_Trace = TRUE to enable or disable trace use sql_trace = FALSE

  (2) to activate the tracing without restarting the databasejust, run the following command using sqlplus:

  SQL > ALTER SYSTEM SET trace_enabled = TRUE; To start the trace
  SQL > ALTER SYSTEM SET trace_enabled = FALSE; To stop the trace

  To activate the traces at the session level

  If you need to generate trace your own sesion use:

  SQL > ALTER SESSION SET sql_trace = TRUE; to start the trace
  SQL > ALTER SESSION SET sql_trace = FALSE; to stop the trace

  or

  SQL > EXECUTE dbms_session.set_sql_trace (TRUE); to start the trace
  SQL > EXECUTE dbms_session.set_sql_trace (FALSE); to stop the trace

  or

  SQL > EXECUTE dbms_support.start_trace; to start the trace
  SQL > EXECUTE dbms_support.stop_trace; to stop the trace

  To enable tracing in a different session

  Discover the SID and the v SERIES No. $ session to help:

  SQL > SELECT * FROM v$ session WHERE osuser = OSUSER;

  and use:

  SQL > EXECUTE dbms_support.start_trace_in_session (SID, SERIAL #); to start the trace
  SQL > EXECUTE dbms_support.stop_trace_in_session (SID, SERIAL #); to stop the trace

  or

  SQL > EXECUTE dbms_system.set_sql_trace_in_session (SID, SERIAL #, TRUE); to start the trace
  SQL > EXECUTE dbms_system.set_sql_trace_in_session (SID, SERIAL #, FALSE); to stop the trace

• SQL Querry has worked in the workshop of SQL but not in series AnyChart.

  Hello

  I use the following statement in SQL Workshop:

  T3.fname | NULL, select ' ' | T3. Lname label, to_char (to_date (t1.total_time, 'sssss'), 'mi: ss') Week_2_Time, t2.total_weight week2_weight

  evt_scr_board t1, evt_scr_board t2, t3 mem_profile

  where t1.mem_serno = t2.mem_serno

  and t1.evt_rnd = 1

  and t2.evt_rnd = 2

  and (t1.rx_cd = 'RX' and t1.evt_rnd = 1)

  and (t2.rx_cd = 'RX' and t2.evt_rnd = 2)

  and t3.mem_serno = t1.mem_serno

  It produces the following as expected:

  

  However when I run the same querry in a series of anychart page shows "No Data".

  

  The querry works fine if I don't need to convert the number to a date format. Any help would be greatly appreciated.

  Thank you!!!

  Syntax for a series is:

  SELECT link, label, value
  FROM ...
  

  In your last example, sysdate week_2_time isn't a value or time.

  The format below for your query would work, but I doubt that is what your waiting for.

  SELECT NULL,
         'Me',
         TO_NUMBER (TO_CHAR (SYSDATE, 'mmddyyyy')) week_2_time,
         135 week_2_weight

• SQL serer: list of databases by using sqlcmd

  Hello

  I have MS SQL 2005 Express running on Windows 7.

  I don't have MS SQL Studio, Toad or etc. and must use only command prompt.

  I know that this server has tables and databases, etc.

  I first run this command:

  sqlcmd %-L

  It returns

  Then I run

  sqlcmd-s %

  1 exec sp_databases

  2. go

  It returns

  DATABASE_NAME DATABASE_SIZE REMARKS

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

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

  1.

  And that's all... that is, it did not return any name database.

  Then I run:

  "' sqlcmd-s % q" select * from information_schema.tables '.

  and it returns 5 names of tables.

  My question: how could I find the database name? Why it is not visible in my case?

  I guess that after I found the base name I could do ' use and then select the declaration...

  Thank you

• OR 9206 Delta sigma or SAR module?

  Hello

  I intend to use the library of waveform for cRIO OR cRIO 9074. I'm having the NI 9206 C series analog input module.

  The question I have is can I use the example of application of Delta-Sigma or the example of SAR acquisition mode.

  Basically, I want to know if the NI 9206 module is a module of delta sigma or a SAR.

  Appreciate your help.

  Swami HI,.

  9206 is a module of SAR, the Delta-Sigma tend to be 24 bits and they have very fixed sampling frequencies that they can run to, if you can set any rate sampling within a range, so it's SAR.

• Canon lens EF 70-200mm L F4 USM + 2 X L series extender

  Hi, I have a Canon lens EF 70-200mm L F4 USM. Now, I want to buy an extension of series X L 2. Can someone help me by informing that AF can work with EF 70-200mm L USM F4 + 2 X Extender mounted on 650 d device and how much image quality I have to make compromises for the same thing.

  mithun_pal129 wrote:

  Thank you all for your valuable comments. I forgot to mention that my intension of extender to my EF 70-200mm L F4 USM in a telephoto lens for wildlife / birds. But now that I'm your stay in Abu Dhabi, he is not paid a lot of bird / wild life. This is why I don't want to spend a lot on super telephoto, and personally, I don't want to go to cheap Sigma lens. So I wanted to do objective 70-200mm + 2 Expander x 140-400 mm. As I myself feel 1.4 X extender is pretty good, but it will give me up to 280mm. I know that's not very good lens for bird / wild raise photography. But you want to know still is feasible or if I use 2 x Extender to make the 400mm autofocus lens is required for the wild life or manual focus can still operate at F8. I don't have a lot of experience in the photography of wild life that's why I wanted to know things.

  In a Word... N °

  Of a 2 X teleconverter on a 70-200/4 made for a lens of 140-400/8 "effective." Due to the reduction of light reaching the AF sensors, your camera will turn off autofocus. A stronger 2 X also "costs" more loss of quality of the image due to the deterioration.

  It is possible to tape on some of the electronic contacts on the focal length multiplier, so that the camera does not know it is there and always try to auto focus. However, the autofocus will be much slower and will tend to hunt much more.

  In some situations, you may be able to manually update. However, effective f8 makes for a pretty weak sight, most cameras update automatic modern as you do not have some fo the features allowing the development manual, vintage cameras designed for the manual focus had in the past. Some people change to one-third of frosted glass to add functionality to support manual focus (split finder image, micro diaprisms, for example). However this requires careful work to install the screen and the display of different can affect precision measurement of the camera, especially in the incorrect Spot metering.

  Addition of a lower 1.4 X teleconverter makes your lens in effect 112-280mm f5.6, who will still be updated with auto focus and will be much less loss of image quality, but not as much 'reach. If yours is a goal IS, it can reasonably be handholdable. If it is not a goal IS, you will need to watch your shutter speeds than blur carefully, probably should keep to 1/500 or more quickly to avoid the camera. Or use a tripod, as suggested by ebibgs, or at least a monopod. You also need to limit the autofocus on your camera to the central AF point only, I think.

  ebiggs1 wrote:

  On your camera, the 70-200mm f4 is like a 112-320mm f4.  With a converter 1. 4 x, looking at 448mm f5.6 and th elong end.  + 400 mm should be long enough for you to get photos of some birds.  BTW, use a tripod.

  While it is technically correct, citing the "crop camera lens factor" in this way may not help much, can be confusing.

  The original poster has simply a 70-200mm lens which they are accustomed to using on a crop sensor camera. They would now like to double the range of this lens on their camera. Crop sensor lens incorporating conversation factor is very useful when the user goes from frame of film/full to reframe the camera or vice versa. For someone who has never used a film camera or has not used one for many years and is now completely accustomed to how behaves a lens of focal length on their device to harvest, it is a completely moot point.

  But what he's basically saying that while you can add a 2 X, it is probably not a good idea for several reasons. Auto focus will work or not, with a few tips, won't work only weakly. Manual focus will be difficult. And the picture quality might take too big a hit, combining a 2 X with your goal. .

  I have a 70-200/4 IS, 70-200/2.8 IS ("Mark I"), 1. 4 X II and 2 X Teleconverters II. I also have long telephoto lenses, so rarely need to add these zooms teleconverter. However if necessary I would use 1.4 X on one of them. But even if AF still work on the 70-200/2.8 + 2 X combo, I won't use it because of the amount of loss of image quality (the most recent IS of 70 - 200/2.8 Mark II and 2 X Mark III are supposed to work together better, than my older versions of each).

  I use mostly 2 X on 300/2.8 and 500/4 lenses privileged where the image quality is still good. (Note: Yes, on some of my cameras 2 X 500/4 causes AF to stop working, as it would on your f4 lens, so I only use the combo on a limited basis.)

  mithun_pal129... I would say the more you get a 1. 4 X and use it with your goal. See if the image quality is to your expectations. Then work to get closer to your subjects. Or bring them closer to you. Practice the techniques of stalking and to study the behaviors of your subjects to discover ways to get closer. Work in a blind and use bait (food, calls). And start saving for a lens of longer focal length.

  The Canon 1.4 X II and III teleconverters are excellent. All Canon teleconverters have mated before elements that limit the lenses that they physically can be attached, but the 70-200 are among those where this is possible. Teleconverter Kenko is another that I see quite often recommended. They have two different levels of quality: a more expensive "Pro 300" version and a cheaper "MC - 4". These are currently offered in versions "DGX" whose operation is very similar to Canon teleconverters. Old Kenko teleconverters "DG" not "reported" to the camera, the camera didn't know they were there, so try to focus.  In the view of users and tests I've seen, the current Kenko Pro 300 DGX is pretty good overall of the entire image area. The MC - 4 cheaper is actually a little sharper in the Center, but not as strong in the corners and the edges of the image. Tamron and Sigma teleconverters also do, but I have little experience or knowledge of the current versions of the people.

  The wildlife/bird photography is not easy. Since no matter how long a goal that you have, there are times when the subjects are just out of reach and all you can go is to sit back and enjoy the show.

  These photos of small subjects with different, but close to or less than the effective focal length even lenses like your 70-200 mm + a 1. 4 X teleconverter would be on your camera...

• PL/SQL dynamic content

  

  I use APEX 4.2.3 on Oracle 11 g R2.

  On my page, I have an IR base I have a column value up as a link to a URL that calls my function javascript in him passing a value of the report line.  Now, I want to display my modal window to display the data in the database for the value that was passed.  The pain I feel is the value of DOM in session state while my content area of pl/sql can be displayed.  The content of pl/sql is just a query that displays data in a tabular presentation specialist.  There are too many values to display in a report the reason for this type of area.  How can I get my DOM value in session state?  My javscript function is stuck.

  Thanks in advance.

  scottm wrote:

  Once again, my IR, a user clicks on the link and the modal display detailed information about the line that has been selected.  I can't really give a lot more other that my query will return just one row of data that will contain 34 columns.  If I set it up as a classic report, it works perfectly, but my users want not displayed like this because they will have to scroll to see all the content.  So my specialized table is really a series of tables stacked with 4 columns each.  I keep thinking of a way to make a report model to view it as I want to, but do not find a way to do it again.  I tried the model "attribute value pairs", but it did not fit on the page completely.  The image below is what I'm shooting.

  

  This layout of the table can be created in a custom report named column model, convert query result of single line into several lines of an HTML table. Something like this:

  Front of the lines

  
  Model of line 1
    
    ...
  and so on
  After the lines
  
  
  
  
  Plant Name
  Plant Type
  Plant Owner
  Year Built
    
  #PLANT_NAME#
  #PLANT_TYPE#
  #PLANT_OWNER#
  #YEAR_BUILT#
    
  Vessel Length
  Disposal Type
  Empty Displacement
  Ocean Certified
    
  #VESSEL_LENGTH#
  #DISPOSAL_TYPE#
  #EMPTY_DISPLACEMENT#
  #OCEAN_CERTFIED#
  
  
  
  

  However, in my opinion, this is limit his use of a table, and I agree with you that the attribute/value pairs (i.e. a list of description) is the correct HTML representation for this data. Assuming suitable browser support, the report can use the model of attribute/value pairs, and then enroll in the space required by displaying it on several columns using a CSS3 multi-column layout.

• SQL question on natural joins

  I am a newbie to SQL and I studied the book of Fundamentals SQL Server Oracle OCA 12 c, but a section on natural joins to confuse me.

  Basically, the author says:

  SELECT r.region_name, d.department_name, l.city, c.country_name

  DEPARTMENTS d

  NATURAL JOIN places l, c countries, regions r;

  The natural join between DEPARTMENTS and LOCATIONS creates a provisional result, consisting of 27 lines since they are implicitly attached on the column of location_id. This set is then Cartesian-joined to the table of the COUNTRY as a join condition is not implicitly or explicitly specified. 27 interim lines are attached to 25 lines in the COUNTRY table, which gives a new temp results set with 675 (27 × 25) rows and three columns: DEPARTMENT_NAME, CITY and COUNTRY_NAME. This set is then attached to the REGION table. Once more, a Cartesian join occurs because column REGION_ID is absent from any join condition. The final result set contains rows and four columns (675 × 4) 2700.

  I can understand because you evaluate joins from the left. But then he wrote:

  The JOIN... USE and JOIN... ON the syntaxes are better suited to join multiple tables. The following query joins four tables using the natural join syntax:

  SELECT country_id region_id, c.country_name, l.city, d.department_name

  DEPARTMENTS d

  NATURAL JOIN places l

  NATURAL JOIN country c

  NATURAL JOIN region r;

  This query generates correctly 27 lines in the final results set since the required join columns are listed in the SELECT clause. The following query illustrates how the JOIN... CLAUSE is used to extract the same 27 lines. A join condition can reference columns only in its scope. In the following example, the join of DEPARTMENTS slots can not reference columns in the COUNTRIES or REGIONS of tables, but the join between the COUNTRIES and REGIONS may refer to any column of four tables involved in the query.

  This second method of the part of the natural writing joined confuses me. I don't understand the logic behind the 2nd series of States of Natural Join. For me, it seems that the first series and the 2nd set look alike, but they are apparently not.

  Can someone tell me the differences?

  Thank you!!

  Hello

  The more important thing to learn more about NATURAL JOIN is: never use it.  If you add new columns, joins can get different results.  I've never heard of someone uisng NATURAL JOIN apart from a manual or a question like yours.

  There are a lot of things in Oracle that take the time to learn and are useful.  All the time you spend learning things is better spent on them.

• Using SQL to ensure the matching records are mutually exclusive.

  There are two tables defined in the following way:

  Table A

  Number 1

  Number 2

  Date

  ROWID

  Table B

  Number 1

  Number 2

  Date

  Identifier of the line

  Each table stores a call between number 1 and 2 on a specific date. The goal is to map exactly one entry of table A with exactly the record in table B

  in a mutually exclusive way. So a single call to a table must be associated with exactly one call the other table (the key is here

  A.Number1 is B.Number1 and A.Number2 = B.Number2). Because it is a relationship is many to many (the number of source and destination may be paired multiple)

  (time), I'm not able to build a series of sql statements that will allow me to get a relationship one between pairs of telephone numbers.

  I'm not allowed to develop a PL/SQL procedure, which would easily solve this problem.

  I was able to find a solution using MIN(Number 1) KEEP (DENSE_RANK FIRST ORDER BY Date) to THE (PARTITION BY x) the form x

  using temporary tables, which allows me to reach a breaking successively much many relationships (i.e. three broken bones in a 01:58 after

  an iteration, and after one iteration, I arrive at a one to one relationship). However, I can't break these relations some n number of times because it requires number n

  hard curls. Therefore, I need a sophisticated solution that will allow me to achieve a relationship one by one.

  Example of

  Table A

  Record 1

  Number 1:451923456789

  Number 2:541969432045

  Date: 29/07/2015-09:01

  Worksheet 2

  Number 1: 451923456789

  Number 2: 541969432045

  Date: 29/07/2015-09:03

  Table B

  Record 1

  Number 1: 451923456789

  Number 2: 541969432045

  Date: 29/07/2015-09:04

  Worksheet 2

  Number 1: 451923456789

  Number 2: 541969432045

  Date: 29/07/2015-09:05

  If we unite our table A and B by A.Number1 = B.Number1 and A.Number2 = B.Number2, we have 4 records. I'm looking for exactly two records.

  The criteria is to associate by the minimum of the sum of the date of the table A table B date. Therefore, the final result should match:

  (1) record 1 of table A with record 1 of table B.

  sheet 2) 2 table A with 2 record in table B.

  So we must do something to reduce the 4 records resulting from the join of two records describe as we see above.

  The result of the join:

  1st row: TableA.Record1 with TableB.Record1

  2nd place: TableA.Record1 with TableB.Record2

  Rank 3: TableA.Record2 with TableB.Record1

  4th place: TableA.Record2 with TableB.Record2

  What I'm looking for, which is easily achievable with a slider, but not with SQL:

  1st row: TableA.Record1 with TableB.Record1

  4th place: TableA.Record2 with TableB.Record2

  Note that if the minimum date condition allows us to select the necessary records, we won't get the expected results. In other words, using the minimum date.

  the results will be:

  1st row: TableA.Record1 with TableB.Record1

  Rank 3: TableA.Record2 with TableB.Record1

  (criteria - table a minimum date)

  or

  1st row: TableA.Record1 with TableB.Record1

  2nd place: TableA.Record1 with TableB.Record2

  (criteria - date minimum table B)

  Two of these results to break the rule are mutually exclusive.

• case in PL/SQL where clause statement

  • Hello
  • I have a research procedure where the user can search on the city, street, zip code.
  • I need meet the 6 different combinations as I don't know what value the user will pass.
  • It should be checked if the user passes the value or not, and then look on values passed.
  • But the procedure below is out.it the slightest mistake can be transformed with if-then-else, but case statement seems much cleaner in the code.
  • procedure searchaddress (pc_town IN SEARCHADDRESS. CITY % TYPE,

  pc_street IN SEARCHADDRESS. TYPICAL STREET %,

  pc_postcode IN SEARCHADDRESS. POSTCODE % TYPE,

  pResultSet to ref_cursor) as

  Start

  Open the pResultset for

  Select searchaddress_pk from searchaddress

  where

  case

  When pc_town is null then ((street = pc_street) and (ZipCode = pc_postcode))

  When pc_street is null then ((town = pc_town) and (ZipCode = pc_postcode))

  When pc_postcode is null then ((town = pc_town) and (street = pc_street))

  When pc_town is null and pc_street is null then (postal code = pc_postcode)

  When pc_street is null and pc_postcode is null then (city = pc_town)

  When pc_town is null and pc_postcode is null then (street = pc_street)

  end

  end searchaddress;

  Thank you

  A basic concept that is important to understand - sliders aren't 'sets of results' (sets of data in memory). A cursor is a series of executable steps (see plans run to cursor). It's like a program. An extraction run the program and output data. In general, which is repeated until the cursor (aka program) is no longer found the corresponding lines.

  A ref cursor is a pointer or a handle for a such slider, passed to a caller, allowing the appellant to interface directly with this slider/program.

  The slider more effective to create a search would be one without superfluous code and predicates and filters. Consider the following approach - a beefier PL/SQL procedure, do not try and play little tricks with SQL predicates in an attempt to create one (and probably not optimal) SQL.

  (not tested/compiled code)

  create or replace procedure SearchAddress(
    town     IN SEARCHADDRESS.TOWN%TYPE,
    street   IN SEARCHADDRESS.STREET%TYPE,
    postcode IN SEARCHADDRESS.POSTCODE%TYPE,
    refCur out ref_cursor
  ) is
    curHandle integer;
    res integer;
    searchSQL varchar2(1000);
  begin
    -- create base query
    searchSQL := 'select searchaddress_pk from searchaddress where 1 = 1 ';
  
    -- add dynamic predicates as needed
    if town is not null then
      searchSQL := searchSQL || 'and town = :town';
    end if;
  
    if street is not null then
      searchSQL := searchSQL || ' and street = :street';
    end if;
  
    if postcode is not null then
      searchSQL := searchSQL || ' and postcode = :postcode';
    end if;
  
    -- create a DBMS_SQL cursor
    curHandle := DBMS_SQL.open_cursor;
    DBMS_SQL.parse( curHandle, searchSQL, DBMS_SQL.NATIVE );
  
     -- bind the dynamic bind variables added as predicate values
    if town is not null then
      DBMS_SQL.Bind_Variable( curHandle, 'town', town );
    end if;
  
    if street is not null then
      DBMS_SQL.Bind_Variable( curHandle, 'street', street );
    end if;
  
    if postcode is not null then
      DBMS_SQL.Bind_Variable( curHandle, 'postcode', postcode );
    end if;
  
    -- execute cursor (to create the cursor program) and pass it back as a ref cursor
    res := DBMS_SQL.Execute( curHandle );
    refCur := DBMS_SQL.To_RefCursor( curHandle );
  end;
