• I need a little help with the INSTR function

  Hello everyone,
  
  im still new to pl sql and experienced an issue with the INSTR function. I need to analyze some values of a CLOB containing the xml code and use INSTR to determine the beginning and end of the value, I would like to analyze.
  
  the data I need is in a <!-[CDATA [[Some Text]]]-> block. up to this point, I managed to take the start of the word, but I can't seem to capture the end of the CDATA block. I use this statement:
  
  POS: = INSTR (TO_CHAR (input_clob) [,'] ', pos2 + 6, 1);
  
  but it doesn't have the desired effect. [It seems to sort of go back to the length of the string, while the]-sign is actually in the xml file. my result would look to "Some Text]]--> < xmlxml >... < / xmlxml >...» ». [I tried to escape by writing ' \] "but if I do, the function returns zero and my parsed string is left blank.
  
  Unfortunately I can't use regular expressions, because I work with oracle 9.2i. Anyone know what I'm doing wrong?
  
  Thank you

  + and = are allowed in URLS. You just have to URL encode like this EncodeURLForQueryString(&AttachUserFileURL) before adding them to your URL:
  GenerateScriptContentURL("EMPLOYEE", "HRMS", Record.WEBLIB_REPT_SJ, Field.ISCRIPT1, "FieldFormula", "IScript_GetAttachment") | "?FileName=" | EncodeURLForQueryString(&AttachUserFileURL);
  
  Here is the entrance of PeopleBook for EncodeURLForQueryString:

• Frame using Vector with the trace function

  Hi all

  When I convert a raster to vector with the trace function, the result is excellent but I want to reduce the number of points, so I have less layers when I import it to the painter. Can anyone advise how to do?

  Rayne

  RayneMaker,

  You can select everything on every layer, Ctrl/CmdClicking on the names of layers, Ctrl / Cmd + A and Ctrl / Cmd + C to copy the whole and then open a new document, deselect the layers of dough remembers in the layers flyout and Ctrl / Cmd + F to insert a single layer.

  I'm still with 10, and there may be more easy/more smart solutions (in later versions).

• Need help with the analytic function

  I want to get the highest employee details and the 2nd highest employee for a particular service. But also the Department should have more than 1 employee.
  I tried the query and it gave me the correct results. But I wonder if there is another solution than to use the subquery.
  
  Here is the table and the query result:
  

  with t as
  (
  select 1 emp_id,3 mgr_id,'Rajesh' emp_name,3999 salary,677 bonus,'HR' dpt_nme from dual union
  select 2 ,3 ,'Gangz',4500,800,'Finance' from dual  union
  select 3 ,4 ,'Sid',8000,12000,'IT' from dual  union
  select 4 ,null,'Ram',5000,677,'HR' from dual  union
  select 5 ,4,'Shyam',6000,677,'IT' from dual union
  select 6 ,4 ,'Ravi',9000,12000,'IT' from dual   
  )
  select * from 
  (select emp_id, mgr_id, emp_name, dpt_nme, salary, row_number() over (partition by dpt_nme order by salary desc) rn from t where dpt_nme in 
  (select dpt_nme from t group by dpt_nme having count(*) > 1)) where rn < 3

  Hello

  You need a subquery, but you don't need more than that.
  Here's a way to eliminate the additional subquery:

  WITH     got_analytics     AS
  (
       SELECT  emp_id,     mgr_id,     emp_name, dpt_nme, salary
       ,     ROW_NUMBER () OVER ( PARTITION BY  dpt_nme
                                 ORDER BY          salary     DESC
                         )         AS rn
       ,     COUNT (*)     OVER ( PARTITION BY  dpt_nme
                                     )         AS dpt_cnt
       FROM     t
  )
  SELECT  emp_id,     mgr_id,     emp_name, dpt_nme, salary
  ,     rn
  FROM     got_analytics
  WHERE     rn     < 3
  AND     dpt_cnt     > 1
  ;
  

  Analytical functions are calculated after the clause WHERE is applied. Since we need to use the results of the analytical ROW_NUMBER function in a WHERE clause, which means that we have to calculate ROW_NUMBER in a subquery and use the results in the WHERE clause of the main query. We can call the COUNT function analytical in the same auxiliary request and use the results in the same WHERE clause of the main query.

  Would what results you if there is a link for the 2nd highest salary in some Department? For example, if you add this line to your sample data:

  select 7 ,3 ,'Sunil',8000,12000,'IT' from dual  union
  

  ? You can use RANK rather than ROW_NUMBER.

  You could be in one of the rare cases where the index should be rebuild, take a look in the following thread:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6601312252730 #69571308712887 (search for 'index of Sweeper')
  Make sure that you have checked if you are in this case before going for an expensive index rebuild.

  Can you help me?

  Published by: Dom Brooks on January 28, 2011 11:26

  Sorry too hasty.

  If you have an index on COL1 and your predicate can use this index, then you might get a BITMAP CONVERSION.

  If you do not have an index on COL1 or you cannot use it, then you will do a FTS.

  Useful relevant info:

  Based on an index function are not used in the expansion of GOLD in 10gR 1 (or beyond - restriction still documented in 11 GR 2)

• Problems with the sound function and scrolling on the touchpad on my Satellite A500/026

  Hello

  I just brought a new laptop A500/026 and when I play music from my ipod I get a little static pop sound at regular intervals during the song... this happens on all my music. I accidentally scroll horizontally through my touhpad and my screen minimizes or maximizes. I try to find how I did it, but can never seem to return to its normal state. There is obviously some sort of function here, can someone help me with it? I installed the x 64 bit version of windows 7.

  Thank you

  Hello

  The touchpad settings are placed in Control Panel-> mouse
  You can find the additional tab which would be you can access touchpad properties.

  As I know the touchpad properties contains many different options that allows you to configure the scrolling function, to activate and assign different actions to the touchpad corners, etc.

  Check it!

• Control values defined by the Index function only works for a running VI?

  I've never used set of control values based on the Index before so I decided to compare it against two other ways to set the controls on the front panel, by using the invoke Ctrl.Val.Set node and nodes for the value property. But if the VI which I am trying to set the controls does not work I get error 1000 say "The VI isn't in a State compatible with this operation." When I run the VI which I am trying to set the controls, I get an error. This is VI really only work if the VI is running? I can't set the values before calling the VI to run dynamically?

  I wonder why you do so in the first place.

  a bit of history. This feature was added to the problem write to items in front by reference is about 1000 times slower than writing to the Terminal. I think that this feature works by writing directly to the transfer buffer. It always ends up by being slower than writing to the Terminal, but only about 10 times slower.

  My company made use of this new feature. We needed it because we have updated thousands of values of frontage on the same VI by reference and labview couldn't keep it up (Yes, probably could have worked around him in a different way, but there is more detail than this...). If your ' e does not update thousands of articles, probably you should not use this feature. Performance savings is not worth the additional development effort it takes.

  It does not work probably because the transfer buffer does not exist when the vi is not running

• Using the data logged in an interface with the aggragate function

  Hello
  
  I'm trying to use logged data from a source table in one of my interfaces in ODI. The problem is that one of the mappings on the columns target implies a function (sum) overall. When I run the interface, I get an error saying not "a group by expression. I checked the code and found that the columns jrn_subscriber, jrn_flag, and jrn_date are included in the select statement, but not in the group by statement (the statement group contains only remiaining two columns of the target table).
  
  Is there a way to get around this? I have to manually change the km? If so how would I go to do it?
  
  Also I'm using Oracle GoldenGate JKM (OGG oracle for oracle).

  "ORA-00979"when the CDC feature (logging) using ODI with Modules of knowledge including the aggregate SQL function works [ID 424344.1]
  Updated 11 March 2009 Type status MODERATE PROBLEM

  In this Document
  Symptoms
  Cause
  Solution
  Alternatives:

  This document is available to you through process of rapid visibility (RaV) of the Oracle's Support and therefore was not subject to an independent technical review.

  Applies to:
  Oracle Data Integrator - Version: 3.2.03.01
  This problem can occur on any platform.
  Symptoms
  After successfully testing UI integration ODI using a function of aggregation such as MIN, MAX, SUM, it is necessary to implement change using tables of Journalized Data Capture operations.

  However, during the execution of the integration Interface to retrieve only records from Journalized, has problems to step load module loading knowledge data and the following message appears in the log of ODI:

  ORA-00979: not a GROUP BY expression
  Cause
  Using the two CDC - logging and functions of aggregation gives rise to complex problems.
  Solution

  Technically, there is a work around for this problem (see below).
  WARNING: Problem of engineers Oracle a severe cautioned that such a type of establishment may give results that are not what could be expected. This is related to how ODI logging is applied in the form of specific logging tables. In this case, the aggregate function works only on the subset that is stored (referenced) in the table of logging and on completeness of the Source table.

  We recommend that you avoid this type of integration set ups Interface.
  Alternatives:

  1. the problem is due to the JRN_ * missing columns in the clause of "group by" SQL generated.

  The work around is to duplicate the knowledge (LKM) loading Module and the clone, change step "Load Data" by editing the tab 'Source on command' and substituting the following statement:
  <%=odiRef.getGrpBy()%>

  with
  <%=odiRef.getGrpBy()%>
  <%if ((odiRef.getGrpBy().length() > 0) && (odiRef.getPop("HAS_JRN").equals("1"))) {%>
  JRN_FLAG, JRN_SUBSCRIBER, JRN_DATE
  <%}%>

  2. it is possible to develop two alternative solutions:

  (a) develop two separate and distinct integration Interfaces:

  * The first integration Interface loads the data into a temporary Table and specify aggregate functions to use in this initial integration Interface.
  * The second integration Interfaces uses the temporary Table as Source. Note that if you create the Table in the Interface, it is necessary to drag and drop Interface for integration into the Source Panel.

  (b) define the two connections to the database so that separate and distinct references to the Interface of two integration server Data Sources (one for the newspaper, one of the other Tables). In this case, the aggregate function will be executed on the schema of the Source.

• STUCK - indexing a list and with the index as a variable

  Hello world. I imagine that this is not a difficult task, but I can't find any information on exactly what I need to accomplish.
  Let's say I have a table with fruits. The name of the fruitid and fruitname fields.
  I have query select * from fruit by fruitname. Then I take this data and create a list (or a table?) with the fruitnames.
  What I want to do is list the results with their place in the list or a table. Not their fruitid. For example:
  1 Apple
  2 Orange
  3 pears
  Where the 1,2,3 is the order of the list and not any recovered data form the query. I need to use the 1,2,3 as variables separately form the Apple, Orange, pear.
  I've been search in the online help, CFWACK and search for information about indexed lists is cheating on me. I was looking at listgetat but the results will be different each time and it just didn't seem like the solution ListGetAt returns the variable... for example:
  Apple Apple
  Orange Orange
  PEAR PEAR
  Any thoughts? Any help in a new direction is welcome. I use CF7.01 on WinServer2003 and SQLServer2008.
  

  Google "".  Find the cfml reference manual page and read it.  Pay special attention to the variables are produced by cfquery.
