• How to get SQL Developer 4.1 to display the query result?

  SQL DEV 4.0.3.16.84 execution of a SELECT statement is stored in a .sql file causes the window of the query result of pop-up indicating the result of a SELECT statement.  SQL DEV 4.1 is not to do so.

  Oops on my part; my SQL formatting has been the root cause.  I got used to insert split without any character of comment lines in front of them.  For example:

  ==================================================

  Select funny business;

  The foregoing indicates the behavior described.

  --==================================================

  Select funny business;

  With the dash double comment shows, the SQL works very well.

  This is different than previous versions of SQL Developer, but is probably better functionality.  I'll try to mark it as answered, but anyone with the admin should certainly do so if I can't.

• Need help to understand the query result

  Hi gurus

  I was reading one of the question here in this forum and its link is below:

  Query required for scenario

  I had some confusion related to this code and don't understand the logic of the out put, see query below:

  Query

  with sub_services as

  (

  )

  Select *.

  of sub_services b

  where exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  )

  order by 2;

  The query result

  12323 A09 3

  12333 6 A09

  12323 HLR1 1

  12323 HLR2 2

  12333 M0CR 7

  12333 4 MO1

  12333 5 MO2

  According to my understanding, the above query should return records in red only because of her is below command

  It exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  but don't know why he's back 7 files, can someone help me understand the result...

  It is query is functionally identical to the PL/SQL block, but much more effective.

  declare

  number of l_res;

  Start

  for line (select *)

  sub_services) loop

  Start

  Select 1 from l_res

  of sub_services

  where su_seq = row.su_seq and

  so_id = "A09" and

  rownum = 1;

  exception when

  NO_DATA_FOUND then

  null;

  end;

  end loop;

  end;

  Essentially every row in the outer query are tested against him exists query.  Given the correlation between two requests is based only on su_seq each line with a su_seq value returned by him is returned in the output.

  Another way to think he uses instead a join condition.  This query is equivalent to the query to exist

  Select the main

  of main sub_services

  Join select (separate su_seq

  of sub_services

  where so_id = "A09") cond

  We main.su_seq = cond.su_seq;

• new to 4.02, no grid or column names in the query results

  It is a bit strange, I have SQL Developer 4.02 just installed, and I don't see grid or column names in the query results.  Don't see anything useful in tools > Preferences, what don't get me?

  The worksheet gives you a couple of different ways to run a query...

  1. instruction execute sheet icon toolbar (large green arrow, or Ctrl + Enter).

  This produces a results tab of the query with the data displayed in a grid.

  2. worksheet icon toolbar Execute the Script (the small tip of the green arrow on lined paper, or F5).

  This produces a tab out of the Script with the data displayed on the printer.

  If execution of the statement to Execute the Script, using some SQL * most orders will remove the column headers:

  1. set the position

  2. set the pagesize 0 (or 1 or 2).

  Pagesize and linesize default is - 1.  By default, the spreadsheet is free for formatting output script as he wishes.  If you have not changed these settings in the spreadsheet, then see if you point to a startup script in Tools > Preferences > Database > name of the connection startup script file

• Consider the function result Cache

  Hello

  Have a question about the function result to cache.

  Follow this link: http://www.oracle.com/technetwork/articles/sql/11g-caching-pooling-088320.html

  I use the following version of oracle: Oracle Database 11g Express Edition Release 11.2.0.2.0

  employees.salary%type result_cache relies_on (employees) is back

  l_salary employees.salary%type;

  Start

  Have a doubt on the am I missed something / do wrong to the result of the setting of the cache settings.

  Have you tried with the following result cache settings

  ALTER SYSTEM SET result_cache_max_size = 2M RANGE = MΘMOIRE

  ALTER SYSTEM SET result_cache_remote_expiration = 2;

  ALTER SYSTEM SET result_cache_mode = {MANUAL |} STRENGTH} - two similar agronomic results

  The wait was to reduce the execution time after its first execution if the data remains the same.

  Please guide me in this regard.

  Thanks in advance,

  PL/SQL function result Cache is only available in Oracle Database Enterprise Edition (EE).

  Concerning

• The query results: extract all lines?

  I was looking for a feature that will allow me to choose to return "all records" in the query results window. The current behavior is fetching 50 files at a time (for example fetch 50 records when you scroll the results = s-l-o-w). What I would do, that is 'Recover all lines' and then use for the scroll bar to scroll "smoothly" to the last record. For example, the 8.0.6 Query Builder version has this feature and SQL Developer 3.0, if I right click on the results. I choose 'Count lines... ". ", looks like it would be a perfect place to put an option"retrieve all rows.

  If your application is to be able to quickly reach the last record in a query you can press Ctrl + Page Down (with emphasis in the grid of results) and you will automatically position your view to the last record in the query automatically go get all the results in the process.

  You have no need to do anything with the mouse scroll is actually the fastest way to reach the desired line.

• Using the Client result Cache

  Hi all

  I have a question about the use of the result of the client cache but first of all, here is the information on my database:

  SQL> SELECT * FROM v$version;
  
  BANNER
  --------------------------------------------------------------------------------
  Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
  PL/SQL Release 11.2.0.1.0 - Production
  CORE    11.2.0.1.0    Production
  TNS for Linux: Version 11.2.0.1.0 - Production
  NLSRTL Version 11.2.0.1.0 - Production
  
  

  I installed the Oracle Client Tools on my clientmachine. There a tnsnames.ora like this:

  ORCL =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = FEA11-119SRV)(PORT = 1521))
      )
      (CONNECT_DATA =
        (SERVICE_NAME = orcl.local)
      )
    )
  
  

  The result of the Client Cache is configured in the sqlnet.ora.

  ADR_BASE = /u01/app/oracle
  OCI_RESULT_CACHE_MAX_SIZE= 2048000
  OCI_RESULT_CACHE_MAX_RSET_SIZE = 1024000
  NAMES.DIRECTORY_PATH = (EZCONNECT, TNSNAMES, HOSTNAME)
  
  

  The Databaseserver is configured like this:

  
  SQL> col name format a30
  SQL> col value format a30
  SQL> SELECT name, value
    2  FROM   v$system_parameter
    3  WHERE  name LIKE '%result_cache%';
  
  NAME                   VALUE
  ------------------------------ ------------------------------
  result_cache_mode           MANUAL
  result_cache_max_size           0
  result_cache_max_result        5
  result_cache_remote_expiration 0
  client_result_cache_size       1073741824
  client_result_cache_lag        3000
  
  

  After you set up a client's server, I try the SQL query on the clientmachine followign:

  sqlplus oracle/password@orcl
  
  set autotrace traceonly explain
  
  SELECT /*+ result_cache */ *
  FROM testtable;
  

  You cannot enable the customer with SQL result cache * more, no matter what you do with parameters. If you install the CD examples, you will find examples of code in cdemoqc.c and cdemoqc2.c that shows how with the OCI calls.

  You probably want to use the result of the server cache, there is a full demo of this here,

• Keep the query results set all paging

  I have a query back thouands of records. For do not impact performance display and paging, which would be the best way without use of query caching? Is it possible to keep the first recordset query time she and her use in Exchange?

  Load balancing definitely throws a wrinkle by using shared memory.  There are ways to address these problems, but they all come with the pros and cons, just basically choose what pros like you and what the disadvantages that you can live with.

  I.E. you can use sessions.  So when a user first access your application, all future queries are sent to the same server that processes requests for first.  But this means that if this server will see, all users currently glued to it are s.o.l.

  I saw other people using databases for the persistent memory.  But then, you have the LAG involved in obtaining data from the database on every request, although it should be easy fast queries to do this.  Side pro, it does not matter which server processes the request.

  It would be different then just re - run the original query every time, but rather store the original query results into a temporary table space so that any complexity which may exist should not be repeated.

• Need help to build the query/pl-sql block to get the query result and the name of column from DB table in the form of key-value pairs.

  Hi Experts,

  I have a DB table has columns of more than 50.

  I question this table, it should only return one line at any time. as sqldeveloper below image.

  

  here, I need to build block pl/sql-query, Discover the column in the table as a key and query result as values.

  Eg:     Key                         -  Value

  TASK_EVENT_ID - 1765

  EVENT_TYPE - ASR_UPDATE

  ... etc until all of the columns in my table.

  Experts please comment on that point, appreciate your help on this.

  Thanks before.

  1. THE query? Sorry, I'm not psychic, but actually write to me.
  2 CTRL-SHIFT-C
