• sql Update query after matching with the string

  I am trying to reach the query that updates a table column with the value of the other table, after that he finds an exact match.
  
  So here's the table data and sample to create.
  

  create table code1 
  (
      codeid number,
      codedesc varchar2(60)
  );
  
  Insert into code1 values ( 1,'R1 CONTRACTS');
  
  Insert into code1 values ( 2,'R2 CONTRACTS');
  
  Insert into code1 values ( 3,'R3 CONTRACTS');
  
  Insert into code1 values ( 4,'R5 CONTRACTS');
  
  Insert into code1 values ( 5,'R9 CONTRACTS');
  
  Insert into code1 values ( 6,'R10 CONTRACTS');
  
  create table table1 
  (   
      tablekey number,
      prefix  varchar2(25),
      codedesc    varchar2(60)
  );
  
  Insert into table1(tablekey,prefix) values (1,'1001PAC');
  
  Insert into table1(tablekey,prefix) values (2,'1001MXT');
  
  Insert into table1(tablekey,prefix) values (3,'1002PAE');
  
  Insert into table1(tablekey,prefix) values (4,'1003PCS');
  
  Insert into table1(tablekey,prefix) values (5,'1004BDX');
  
  Insert into table1(tablekey,prefix) values (6,'1005PAC');
  
  Insert into table1(tablekey,prefix) values (7,'1006PAC');
  
  Insert into table1(tablekey,prefix) values (8,'1007LDR');
  
  Insert into table1(tablekey,prefix) values (9,'1009LCR');
  
  Insert into table1(tablekey,prefix) values (10,'1010LBR');
  
  Insert into table1(tablekey,prefix) values (11,'ABCDEF');

  I'm writing a query that would update the value of column - codedesc (currently Null) of the table1 table: after it is a string of column - table code1 codedesc.
  
  The logic for the match is, - take - 2nd column of table-codedesc code value and get 2 characters. For example, when the string is - R1 CONTRACTS, the string will be 1. (Select substr ("R1 CONTRACTS, 2, 2) of the double). -Output will be 1.
  
  Now,.
  Look in table 1 for the 3rd position of the prefix that corresponds to the string returned by the query above. So, if the prefix is '1001PAC', it should look for 2 value of figures from the 3rd position. So, in this case it will be 01. Digitally 01 and 1 are equal, then the match is found for this line in the table1 table, so we will need to update the value of the column codedesc with the "contracts of R1.
  

      tablekey,    prefix            codedesc    
  ---------- ------------------------------------------------------------
  
        1               1001PAC     R1 CONTRACTS    -- Needs to be update with this value. 
        2               1001MXT     R1 CONTRACTS
        3               1002PAE      R2 CONTRACTS
  ...
        11             ABCDEF                                --Null ( No Need to update when no match found).

  Hello

  You want to avoid TO_NUMBER, given that will cause an error if even a line has a number no (except space) in the wrong place.
  Use RTRIM to remove extra spaces at the end of the match_key and LPAD to add '0', if necessary, at the beginning:

  MERGE INTO     table1          dst
  USING   (
            SELECT  LPAD ( RTRIM ( SUBSTR ( codedesc
                                   , 2
                                 , 2
                                 )
                            )
                       , 2
                       , '0'
                       )          AS match_key
            ,     codedesc
            FROM     code1
       )               src
  ON     (src.match_key     = SUBSTR ( dst.prefix
                         , 3
                       , 2
                       )
       )
  WHEN MATCHED THEN UPDATE
       SET     dst.codedesc     = src.codedesc

• Query SQL Report with condition (multiple settings) at the point of the apex?

  Hi all
  
  I have a small problem and cannot find a solution.
  
  I need to create reports based on a query, SQL or I.R. Nothing hard here.
  I need to add the WHERE clause dynamically with javascript to an element of the Apex.
  Even once is not very difficult. I set the agenda of the Summit, put my query like this "SELECT * FROM MYTAB WHERE COL1 =: P1_SEARCH" then I call the page by setting the P1_SEARCH value. For example, COL1 is rowid. It works very well.
  
  But here's my problem. Consider that P1_SEARCH contains several ROWID, and I don't know the number of these values,
  (no I don't create a large number of items and create a query with so much GOLD!), I would sotheming like "SELECT * FROM MYTAB WHERE ROWID IN (: P1_SEARCH) with something like: ROWID1, ROWID2 in P1_SEARCH."
  
  I also tried: 'ROWID1, ROWID2' and 'ROWID1', 'ROWID2 '.
  but I can't get anything else than the mistake of filter. It works with a value, but as soon as there are two values or more, it seems that the Apex is unable to read the string.
  
  
  How can I do it please?
  
  Thanks for your help.

  For a standard report, see + {message identifier: = 9609120} +.

  For an IR - and improve safety by avoiding the risk of SQL Injection, use a collection containing the values in a column instead of a CSV list:
  {code}
  SELECT * FROM MYTAB WHERE ROWID IN (SELECT c001 FROM apex_collections WHERE collection_name = "P1_SEARCH")
  {code}

• PL/SQL Query return function, adding the column links

  Hi all
  
  I'm working on a SQL report with the area type = function from PL/SQL Query to return
  All columns are generated dynamically based on my mapping table and a column of ID.
  So whenever the page is loaded, according to the ID mapping table returns a set of columns in a particular order.
  So not only the columns are dynamic, but the order of the columns varies also.
  But the first 1 column is standard (it doesn't come from the mapping table) and is coded in my pl/sql block hard.
  
  I'm fighting with the addition of a link to this column. The link must be a Javascript function which takes the parameters in the form of 2 columns in the mapping table.
  My pl/sql block is something like that...

  v_select := 'SELECT <g href=javascript:f_report1(#map_id#,#comments#)><img src=""></a> as report1, ';  // g=a
  v_cols := 'contains all columns from the mapping table based on a ID(hidden item)';
  v_from := 'FROM table';
  v_where := 'where condition is put in here';
  v_query := v_select||v_from||v_where;
  return v_query;

  Now, I'm not able to transmit the values of this #map_id # and #comments # correctly. I tried so many different combinations of channels, but could not make it work.
  
  I'm not sure that the order of this map_id and commentscolumn and therefore cannot connect through the report attributes.
  How can I go to a column value to the function?
  
  
  
  Thank you

  select  owner,

• SQL query to find out the version of discoverer

  Hello
  As a developer, is there a query sql DB the dorsal (or script) that can be run on DB to find out the version of Oracle Discoverer installed?
  The query will be different if the discoverer is used with the Oracle Applications (R12.1.3) compared to a Scout running on a plain stand alone Oracle database (Oracle applications not)?
  
  Thank you
  GG.

  Hello gg

  The VER_NAME and the VER_DESCRIPTION are usually never filled and can be ignnored.

  The VER_RELEASE is the NLY version as you rightly summised. This version is 100% compatible with the discoverer 11g and if you already have it you can go from 10g to 11g without changing anything in the EUL

  VER_MIN_CODE_VER is the minimum version of Oracle Discoverer which can be used with this EUL. In this case, 10.1.2.45.20 is 10g Release 2

  VER_EUL_TIMESTAMP is the date and time, this version of the EUL was published by Oracle - again you can ignore it

  Important fields are VER_RELEASE and VER_MIN_CODE_VER

  Hope this helps

• How to escape text in the query pattern to avoid the SQL Injection

  We plan to use Oracle Text to search for in a Java web application and use a query template as shown below, but are concerned about SQL Injection attacks. In general, we use a parameter query, but that does not seem possible with these search patterns. Is there advice or recommended to avoid SQL Injection when using query patterns - what characters need to be escaped or cleaned the entry user, etc? Or is there another approach to query patterns which does the same thing, but can use the settings?
  
  Select (1) score, my_id from my_table where CONTAINS (search_dummy,
  ' < query >

  ORDER BY SCORE (1) DESC;
  
  Thanks in advance for any help or advice!

  You should be able to put the entire query to the CONTAINS clause argument in a variable binding. Prevent SQL injection. It is possible they could do 'contains the injection' and perform research of the else clause contains this as your intention, but unless you are relying on a part of contains the clause to implement security, that shouldn't be a problem.

• Production PL/SQL query: can not find the error

  I have a PL/SQL which produces a query for me, which is used to fill out a report. I use this to supply a filter/search form. Since I want to only filter using xxx movies WHERE = yyy when yyy actually has something else NULL, I use a PL/SQL script in the query I need to produce. However, it does not work as expected and I can't understand why. Here is my code:
  

  DECLARE
    query VARCHAR(1000);
  BEGIN
    query := 'SELECT * FROM F_OBJEKTE WHERE 1=1 ';
    IF :P15_REGION != null THEN
      query := query || 'AND REGION = :P15_REGION ';
    END IF; 
    RETURN query;
  END;

  However, the report still contains all lines, as if P15_REGION has not been defined - and so I guess that the script never enters the IF part. Everyone around who can enlighten me, why it is?
  
  Just another little thing: is there a way I can print debugging messages I see when I press the "Debug" button on the lower bar of APEX? It would help a lot of debugging such PL/SQL functions.

  Try changing

  IF: P15_REGION! = null THEN

• Question related to the execution of the query by using the links to the DB

  Hi all

  I have a source and target database. Both are 11.2.0.3.

  I have a query that is running on the source database and load data into the target database.

  I created synonyms in the target for all of the tables referenced in the query, remaining at the source.

  I run the query in the target using synonyms that I created. I see that the entire query became transferred to the source database and executed. The execution plan of the source was exactly the same as the way in which we could, if the query has been run directly there.

  No problems so far.

  Now, I have a database from different sources. Version 11.2.0.4.

  When I try to mimic the same behavior using this data source, the complete query will NOT be transferred to the source. He made on the source (remote site) full table scans, transfer of data to the target (local site) and then by performing sort operations & the index range scans (min/max) on the target.

  In both cases, all of the tables referenced in the query are accessible through the link in the DB.

  Please let me know if there is no setting of database / everything which could control how or where a query with all accessible by link DB tables are optimized and executed? Ideally, I want the entire query to be transferred to the remote and executed site.

  I can provide more details if necessary.

  Thanks in advance.

  Thank you sol.beach. Queries I tried both sources are in fact different. I failed to mention that.

  @John,

  We did recommend the creation of a view of the source, which is synonym on target and run the query. The client was not ready to create any object on the source system and so to test this workaround solution.

  ********************************************

  After some time, I realized that there is a hardcoded as SYSDATE column. Whenever I took it / I did as null, because the entire query is getting transferred to the source DB.

  "I changed 'SYSDATE column-name' to ' col_name (select SYSDATE from dual@remote_db_link). But this also seems to stop the query to be sent to the remote db as a whole.

  Try to work around this problem, but any ideas are much appreciated.

• Are constants of body of the PL/SQL Package in the shared or private area

  Based on that it is not clear to me if body Package PL/SQL constants are stored in the shared or private area.

  "PL/SQL program units and the Shared Pool
  
  Oracle database treats PL/SQL program units (anonymous blocks, procedures, functions, packages and triggers in database) much the same way he treats the individual SQL statements. Oracle database allocates a shared area to hold the shape analyzed, compiled a program unit. Oracle database allocates a private space to hold values specific to the session who runs the program unit, including local, global and package variables (also known as the package is instantiated) and stamps of SQL execution. If more than one user is running the same program unit, a place unique and shared is used by all users, while each user runs a separate copy of his own private SQL area containing session-specific values.
  
  The individual SQL statements contained in a PL/SQL program unit are processed as described in the previous sections. Despite their origins within a PL/SQL program unit, these SQL statements use a shared area to hold their analysed representations and a private space for each session, who executes the statement. »

  But I still have to ask because it seems still more particularly in example 1 that the constant can be attributed to the use that the actual value could be a pointer to a constant string value in a table of symbols or something related to the compilation unit. I'm always curious in a perspective of management of memory if there is a difference between the example 1 and example 2, and if one is better and why.

  The storage is real, references to this storage internal to the PL/SQL engine. And irrelevant to the PL/SQL programmer.

  This question is really a disagreement over the shape is better: example 1 or example 2. I prefer the 1 example, for readability, testability, etc., and so the question is where is the performance of the memory/differences and or is it just preference of developer.

  I agree with rp0428 - he raised a very important point that it is a problem of scope and nothing else.

  Basically is there any trade-off between using one shape on the other insofar as the performance and memory management?

  Not really. Most runtime engines release not just actual system memory when a variable is out of range. the malloc() calls are expensive. Free() calls are expensive (and are not always the result in usable free memory which can be malloc'ed again).

  Several execution engines use what is called a managed heap. A malloc is made of a new process when it is initialized. The heap memory / managed malloc'ed is adjacent. Pointer allocation of memory for this process is initially pointing to the base of the managed heap. As the process allocates / uses memory, the pointer is moved just advance in the managed heap, which indicates the HWM as such - the beginning of the 'free' memory in the heap. Allocation is sequential.

  Reset of your variable execution, or releasing your runtime object, does not reset the HWM as other objects/variables can still be used and located after this place in the bunch. In this case set him free memory by releasing / resetting the language variables does not restore the kernel memory.

  Memory management is a sophisticated process entirely processed by the engine running - and best left to the runtime engine. As you as a programmer do not explicitly control the memory management, it is not a good idea to try to write code that artificially attempt to use 'better' for the runtime engine memory management. The next version of the runtime of that aura of new features, optimizations and so on — and your interference in your code to get the "valorisation" of memory can happen just bite you not bad after an upgrade to execution.

  Regarding the performance aspect - variable initialization is dependent on scope. In order to have a global scope means a one-time initialization, whereas a private scope (created each call) is a multiple unit. If the first is a little faster than the latter.

  However, the performance differences are tiny - IMO too small to justify this as a valid consideration to spend in addition to the decision of functional design on what possibilities a variable or a constant need to have.

  A second difference 0.0000046 in a single execution for FooLib.Exec between the use of package for the constant scope, against increased private. Which means that the issue of the scope is not a decision of the performance. Not when improving performance overhead is 0,0046 millisecs.

• SQL Server, get the event ID 10016 hourly

  Hi guys,.

  We get the error message below on our SQL with OS WS2012 server every hour.

  "The application-specific permission settings do not grant permission to local Activation for the application server COM with the CLSID.

  {FDC3723D-1588-4BA3-92D4-42C430735D7D}

  and APPID

  {83B33982-693D-4824-B42E-7196AE61BB05}

  the user NT SERVICE\SQLAgent$ IBSQL2012 SID (S-1-5-80-485265429-2350460967-4062759752-2586802043-2488535659) from address LocalHost (using LRPC) running in the container of the application unavailable SID (not available). This security permission can be modified using the Component Services administrative tool. »

  I have been through a few threats and read it from another post on the internet, but under Component Services, tab of the particular service related to this message (based on its APPID) I see that SYSTEM is already added and it has the Launch Local and local Activation permissions granted to the security.

  Why are we always get that number, because instead of local authorities, we should give remote "..." from LocalHost (using LRPC) address... » ?

• Query SQL with DB data across links

  Hi Experts,

  Please give some guidance on below question.

  I have a pre-built SQL that I use to develop a report of BI Publisher and this query uses a database link to get values from another database instance.

  Now when I try to create a data set, I get the error "ORA-02019: description of the connection to the remote database not found. '

  I'm assuming that when I try to point to a data source, the editor of BI is pick the link of database as another data source and he could not find it and as well throw this error.

  Let me know how we can manage the links of the db in the data set.

  Thank you

  Thanks for the reply KKT.

  I solved the problem. It was related to the issue of access to the db link. The BI user in the JDBC connection did not have access to the db link.

  The DBA team gave related and resulting access fixed.

  Thank you
