• JSON to the sql result set

  Hi all

  I have this requirement to convert the JSON format in the result set (with the lines and columns).

  is their in any case I can achieve this?

  I was able to successfully convert the sql result set in JSON format but difficult time to do the reverse.

  Flexibility:

  At some point, I expect the lines to return no more than 2 & about 50 columns maximum.

  Therefore, the JSON itself can be stored in varchar2 (4000) and not need to use CLOB. (If necessary to be passed as an argument to the function).

• Export a sql result with the right button of the mouse

  We do not have the ability to export the sql result to in Developer SQL EA 3.0.4. I have very difficult ofr me, because all day in my service allows us to export to excel or export format insert,...
  
  We have 2 versions of the SQL (3 and 2.1) developer only because there is no such thing as this feature in 3.0.
  
  Do you have a solution for Developer SQL EA 3.0?

  In the EA, it's called Unload , but do not get 3.0 production, where he's back for the export .

• dash line, show by sql result

  Hi, there are 2 choices to view the results for the guest (choices in the command prompt).
  
  "All values" and "SQL result."
  
  I found that for all values, the results are SEPARATE.
  for SQL result, if the sql code is "select... from...» ', the results may be unique (choice duplicated in the command prompt)
  If the sql code is "select DISTINCT... of...» ", the results are still not unqiue (double choice in the command prompt).
  
  is this a bug? or SEPARATE only is not supported?

  Hello

  I don't think that there is a need to SEPARATE in the select clause. Default BI Server will apply separate in the application and go to the database. This is true for all non-primary key columns only specific columns. Here is an example,

  There are some duplicate values in the column of the subregion. But even if I give the sql code following in guest of dashboard for the 'Results' option it again retrieves unique records.

  SELECT customers. Sub-region of countries "OF HS

  BI Server generated query:
  Select distinct T175. COUNTRY_SUBREGION C1
  Of
  SH COUNTRY T175

• Add the variable of presentation in a prompt SQL results

  Hello friends!
  
  I have a prompt with the time Dimension (year (p.v. v_year) and month (p.v. v_month)). Then I have another guest of departments in the same page and I want to compel departments depends on my year and selected months before.
  
  I know to do with variable presentation, if I go to SQL results in prompt Department and ADD the following: "WHERE"Sun Time"." Year=@{v_year}"it works but I want to add months also!

• Pivot SQL results

  Hello

  Can someone help me with a request to one of our business units.

  We have pieces of equipment that have IDS and descriptions. A piece of equipment can have between 0 and n descriptions. Most have 1 desc, some don't any others maybe 5 or 6.

  Therefore, currently the .NET application presents the data as follows (I've simplified it a lot...)

  Select equipment_id, desc

  of equipment_desc;

  equipment_id / / desc

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

  12345 xxxxx

  yyyyy 12345

  zzzzz 12345

  NULL 98765

  KKKKK 78910

  .

  .

  That request to the end-user at the moment is for data must be rotated and presented like this;

  equipment_id desc_1 desc_2 desc_3

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

  12345 xxxxx yyyyy-zzzzz

  NULL NULL NULL 98765

  KKKKK 78910 NULL NULL

  So, as you can see I still want 98765 even if there is no description.

  I did something similar to this was a CASE statement, but I knew exactly how much passes description there were, as mentioned previously, it is configurable, so it might be 0 or n?

  Guidance or advice much appreciated.

  Thank you

  Grand... and now you have a query that is generated dynamically, providing an unknown number of columns through a slider REF... so you're going to need either a 3rd layer application of party which can cope with a projection of a ref cursor dynamic SQL or you will have to write code PL/SQL dynamic to manage dynamic results. or, if in 11g, use the DBMS_SQL package to convert the ref cursor in a DBMS_SQL cursor and uses the code to analyze and process the results of the query on a base of column position rather than on basis of name of column.  It's a lot of work and is likely to lead to problems of heavy maintenance.

  The real need to have a dynamic number of columns output is something that is often necessary to run reports on the data.

  As a result, most report writing tools are perfectly capable to query the data in the normal way and then rotate dynamically for the presentation of the report.

  SQL and PL/SQL are not the best tools for rotating dynamics.

• AWR time model statistics vs SQL Statistics

  Looking at an AWR report took on a unique snapshot interval, I note the following:
  
  In time model statistics, DB time is listed as 161,47 seconds, with sql execute represents the time of 127,83 seconds.
  
  When I DBA_HIST_SQLSTAT to queries on the same cliché and summarize all the elapsed_time_delta of each SQL stored in AWR, I find that it's 132,05 seconds, even after filtering of all PL/SQL (command_type 47) and each SQL with parsing_schema_name SYS.
  
  If anything, I expect this sum less than that contained in the statistics of the model time, thinking that only the top n sql is included in DBA_HISSQLSTAT.
  
  Does anyone know where my reasoning was an error?

  Yes, I understand. Here you can not because the statistical statement have no knowledge of what what call. This is probably why Oracle introduced the chronological model: it gives information that you can't derive from other sources.

  Any timed operation will be buffer at most 5 seconds of time data. This means that if a timed (such as the SQL execution) takes a long period of time to perform, the data published to this point of view lack maximum 5 seconds of the time accumulated for the operation.

  Can't really make sense of interpretation which

  means that the value may be missed for 5 seconds for each running of instruction.

  Is it really what you see? "Do not enter value for DDMMYYYY '?
  Be sure to view the results you get in fact from the code you post.

  Probably the best way is to explicitly set substritution variables before you start curling, like this:

  set serveroutput off
  set feed off
  set lines 200
  set pages 2000
  set verify off
  set term on
  column object_name format a30
  
  ACCEPT  schema_name       PROMPT "Please enter the schema name (case-sensitive, e.g. CUSTOM): "
  ACCEPT     ddmmyyyy       PROMPT "Please enter the minimum created date (DDMMYYY, e.g. 28022011): "
  
  spool result_ddl.lst
  
  select     dbms_metadata.get_ddl(object_type,object_name)
       ||     ';'
  from    dba_objects
  where      owner_name     ='&schema_name'
  and     created          >= to_date ('&DDMMYYYY', 'DDMMYYYY')
  ;
  
  ...
  

  Beware of round-trip conversions, such as

  to_date(to_char ...
  

  They are almost never necessary in Oracle. If you have a reason why you can't use just created, then it is almost certainly to get the same results without changing the types of data more efficiently (and less confusing).

• Display SQL results in flash

  Hi all

  Can someone tell me how I would go about setting up flash to display the results returned by a query SQL, one at a time.  I can work on the query and PHP, but want I want to know, how to do flash take each of them and animate it, including the suspension and the compensation of the full screen, and then continues on a screen of 'new '.  That's essentially a list of events in a database.

  So, while watching the movie in action, you'd see

  White screen

  Event 1 (break)

  Tournament 2 (pause)

  Event 3 (pause)

  (make one pause and fade out)

  New screen

  Event 4

  Event 5

  Event 6

  .. and so on until all the results have been posted.

  Any help much appreciated.  In fact, it is possible that what I need is help as to how to achieve this returning from xml.  It's really the actionscript code that I am lost.

  Thank you

  James

  If you do not have a handle on the management of dynamic content in Flash, and then to the time you should focus on solving just this aspect and save with php/sql/xml eventually.  To creat now just a stufff array you want to treat it the way you want and it works from there.  Eventually, that's what you get when you feed the file, the data anyway.

  As far as the break and the animation of the aspects go, your best bet will be to search Google for a tutorial on perhaps a slideshow or marquee that runs automatically.  Understand how it works, and then find a way to turn it into something that suits your needs.

  The basic tools that you will be after will be the Tween class to animate the Timer class to trigger a break/motion, as well as their respective event listeners.  If you can find some simple tutorials just for these two things separately, you might be able to reason about the merger for what you are after.

• Odd SQL results

  I have a SQL statement which shows a strange behavior. When I run the present:
  
  SELECT vfn.cat
  IN v_mult_category
  OF vfn, valid_fishery vf vps_fishery_ner
  WHERE vfn.plan = vf.plan
  AND vfn.cat = vf.cat
  AND vf.permit_year = p_Fishing_Year
  AND vf.moratorium_fishery 't ='
  AND vfn.vp_num = p_permit_number
  AND vfn.ap_year = p_Fishing_Year
  AND vfn.plan = 'MUL '.
  AND date_issued = (SELECT MAX (date_issued)
  OF vps_fishery_ner vfn
  WHERE vfn.vp_num = p_Permit_Number
  AND vfn.ap_year = p_Fishing_Year);
  
  This is supposed to go back to the category "A" for the number of permits given and the fishing year.
  But it returns nothing. But when I add TRUNC at both sides of the line of date_issued, as seen below, it does not return the "a."
  
  SELECT vfn.cat
  OF vfn, valid_fishery vf vps_fishery_ner
  WHERE vfn.plan = vf.plan
  AND vfn.cat = vf.cat
  AND vf.permit_year = 2010
  AND vf.moratorium_fishery 't ='
  AND vfn.vp_num = 111111
  AND vfn.ap_year = 2010
  AND vfn.plan = 'MUL '.
  AND TRUNC (date_issued) = (SELECT MAX (TRUNC (date_issued))
  OF vps_fishery_ner vfn
  WHERE vfn.vp_num = 111111
  AND vfn.ap_year = 2010);
  
  I don't know why it would work. If truncating the two sides works, should not do not truncate each side return a value?

  Well your subquery to set the maximum date is not all clauses that are in the body of the request. It therefore generates a maximum based on a larger result set then the dates you compare it with that.
  Coincidentally, the maximum date is the same day as one of the files in the body of the request, in order to for the truncated dates. but it's at a different time, so direct comparison does not work.

  It should work

  SELECT vfn.cat
  INTO v_mult_category
  FROM vps_fishery_ner vfn, valid_fishery vf
  WHERE vfn.plan = vf.plan
  AND vfn.cat = vf.cat
  AND vf.permit_year = p_Fishing_Year
  AND vf.moratorium_fishery = 'T'
  AND vfn.vp_num = p_permit_number
  AND vfn.ap_year = p_Fishing_Year
  AND vfn.plan = 'MUL'
  AND date_issued = (SELECT MAX(date_issued)
  FROM vps_fishery_ner vfn, valid_fishery vf
  WHERE vfn.plan = vf.plan
  AND vfn.cat = vf.cat
  AND vf.permit_year = p_Fishing_Year
  AND vf.moratorium_fishery = 'T'
  AND vfn.vp_num = p_permit_number
  AND vfn.ap_year = p_Fishing_Year
  AND vfn.plan = 'MUL');
  

• want to extract two values from rows in a single sql result

  Let me first of all explain the situation
  
  I have two tables
  1 Animal_details(animal_id,and other details)
  2 Animal_weight(animal_id,seq_no,weight,date_weighed)
  
  in fact situation here is that for each weight I am inserting a new line with seq_no say
  1 for the first weight
  2 for the second weight...
  with their weight and date
  for example. animal_id = 1 seq_no = 1, weight = 200, date_weighed = 12-may-2000;
  animal_id = 1, seq_no = 2, weight = 250, date_weighed = June 12, 2000;
  
  means seq_no = 1 represents 1 weight of animals
  seq_no = 2 represents 2 weight of animals
  
  how an animal can have any number. weighted times.
  
  now what I want, I want to show a result with
  
  animal_id, weight_1, weight_2 with other animals details in a single line
  
  How can I get first weight and the second or more weight in the same line for any animal?
  
  Please answer soon, its urgency.
  
  Thank you

  You cannot issue a SQL with dynamic column list of 100%. What you can do is something like the questions:

  with t as (
             select  animal_id,
                     max(case seq_no = 1 then weight end) first_weight,
                     max(case seq_no = 2 then weight end) second_weight,
                     max(case seq_no = 3 then weight end) third_weight
               from  animal _weight
               where seq_no <= 3
               group by animal_id
            )
  select  t1.animal_id,
          first_weight,
          second_weight,
          third_weight,
          other_details
    from  t t1,
          animal_details t2

• Model for caching the results of database queries?

  I am interested in the caching of certain common and slow query results in a cache consistency and would like some suggestions on models of 'good '.
  
  In this case you would use a cache next to the model to the data stored in the cache/database where all updates are written to the cache and the database using a XA transaction (we need to do it this way because there are certain requirements of coherence that are difficult to check (at least with correct performance) by using only the cache). We intend to use a "near cache" with a rear limited size.
  
  We plan to invalidate the "saved query result cache" as part of each transaction update (we have a few simple rules which determine what query results that must be discarded for each change).
  
  The part that is a bit tricky is to make sure that no application is perhaps underway while an update of the data related to the query is also underway where the invalidation might be carried out until the result of the query is inserted in result cache... I am not concerned about order of exact time between queries and updates that are ongoing at the same time, but must be 100% sure that no "outdated" information remains (or can be inserted!) in the cache after the update was signed...
  
  It is not enough to rely on the expiration of the time based on the result cache (I would have to set the time so short that the cache would not give a lot of improvement)
  
  I think something like the following:
  
  When you perform a query (which can already caching):
  
  1. do a dirty read against the result cache to determine if a query with the specified result already exists here - if so use it!
  2. If it is not found lock, a key with the specified parameter, and when the lock is obtained to check once more that there is still no value, if there now to unlock and use it!
  3. If there is still no value run the database query, save the result in the cache, unlock and use the result
  
  
  When you make a change using a XA transaction:
  Remove records from query results in the cache corresponding to the changes - this can be done without first checking if there is really no result for the parameter or not.
  I guess the stage of preparation of the transaction will lock the deleted records in the cache of query result preventing the invalidations and simultaneous updates...
  
  Everyone sees a few windows of vulnerability here? For example, it is possible that the cache owned by the XA transaction lock is released before the update of the database has finished (thus a request could be carried out against the old data and be stored in the cache after the invalidation have been performed) or what exactly the kind of problems that the XA protocol designed to prevent?
  
  An alternative I've been thinking about how to run the database query / caching the result would be to leave a store class hides (for query result cache) execute queries when no entries exist in the cache, but I don't know how I would change the locking protocol to make it work - can I still lock a cache by this type or component entry , or which would result in a block?
  
  Suggestions, thoughts etc. are much appreciated!
  
  Best regards
  Magnus

  Hi Magnus,

  Everyone sees a few windows of vulnerability here? For example, it is possible that the cache owned by the XA transaction lock is released before the update of the database has finished (thus a request could be carried out against the old data and be stored in the cache after the invalidation have been performed) or what exactly the kind of problems that the XA protocol designed to prevent?

  If the query is executed as you described and your application can take the same lock of keys to query before you update the data and only released the lock, once the transaction is complete, you can be assured that a query based on outdated information will not be cached after the transaction. If you want to be sure that no stale query results will be returned, remove the result cached outside of the transaction just before the validation of the transaction.

  An alternative I've been thinking about how to run the database query / caching the result would be to leave a store class hides (for query result cache) execute queries when no entries exist in the cache, but I don't know how I would change the locking protocol to make it work - can I still lock a cache by this type or component entry , or which would result in a block?

  I think that you can implement a class of dumps for query result cache that can be used to provide the appropriate locking device. If implemented correctly, I don't think that there is a risk of blocking.

  Kind regards
