• I want to analyze the values from a string

  Hello.. I want to analyze certain values in a string... it's values in my channel...

  anyType{NewDataSet=anyType{Table=anyType
  {SINo=5; ProductId=33;productname=aaa;
  price=543;};Table=anyType{SINo=1;
  ProductId=111;productname=bbb;price=543;};};}
  

  I need to display my SINo, ProductId, productname and price... everything separately... is it possible? or is it possible to convert this string to an xml and then parse the values?

  You can write a function to split this string with respect to the level of a delimiter, in this case '=' can be used, like the Split function available in the string for the Desktop Java class.

  This function returns an array of strings in which the split string values is stored.

• Install Oracle GoldenGate Linux to synchronize two schemas from database on a single server

  Hi all

  I have to synchronize two schemas from database (Oracle 12 c) in a single host RedHat Linux to demonstrate and understand the use of OGG V12.1.2.1.0. I try to do. But it's complicated and confused me because I am new to Oracle and Linux. I followed this tutorial ( install Oracle GoldenGate for Oracle 12.1.2 on CentOS/6.x to 6.x/RHEL Linux 6.x EL ). But it is difficult to understand how I can match with two diagrams of database on a single server.

  
  And I found this tutorial (Oracle GoldenGate on Linux: two-way replication of Oracle 11 GR 2 to Oracle 11 g 2). He said: "" If you have that one host, it may be useful to change the /etc/hosts file to create aliases forhost01.example.com and host02.example.com.". What it really means?

  The other seems to be useful. But it's totally different from 1. Is that this will help my job since I use 12 c Oracle Server?

  Can I get some tips to continue my task?

  Here's another tutorial - http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/goldengate/12c/OGG12c_Integrated_Replicat/index.html

  It has everything set up on a single Linux host.

     </s:Body>

  I need to retrieve the Id of the node FacilitySiteInteraction - in this case, the values are 78104 and 78105.
  
  I tried to use extractvalue just, but he hesitates with error ORA-19025.
  

  select extractvalue(x,'//FacilitySiteInteractionList/FacilitySiteInteraction/Id','xmlns="urn:WA.Ecy.ADS.FacilitySite.Services"')
  from my_tab;
  
  ERROR at line 2:
  ORA-19025: EXTRACTVALUE returns value of only one node
  
  -- note: column my_tab.x is an xmltype data type

  If I use just extracted I see there the rub

  select extract(x,'//FacilitySiteInteractionList/FacilitySiteInteraction/Id',
  'xmlns="urn:WA.Ecy.ADS.FacilitySite.Services"')
  from my_tab;
  
  <Id xmlns="urn:WA.Ecy.ADS.FacilitySite.Services">78105</Id><Id xmlns="urn:WA.Ecy.ADS.FacilitySite.Services">78104</Id>

  The format of the XML document does not have to consider another records/lines.
  
  So, the next thing I tried was using the value of the iterator:
  

  select extractvalue(x,'//FacilitySiteInteractionList/FacilitySiteInteraction[2]/Id',
  'xmlns="urn:WA.Ecy.ADS.FacilitySite.Services"')
  from my_tab;
  
  78104

  The downside of what I see is that I must first enter the TotalRowCount value and then more wrap XML Document TotalRowCount times
  in order to get these values. So I was wondering if it is a more effective approach to enter these data?
  
  Thank you, Tony

• Another REGEXP question: how to extract multiple values from a string

  Hi, how can I retrieve multiple values to a string with RegExp with Oracle SQL constructs?
  
  Have looked at the various examples, I cannot understand this.
  the following Sql code

  select
     regexp_substr(sessie."rollen", 'CN=A_role') "A_role"
     from ( 
  select '
  CN=A_role,OU=a_org_unit,OU=another_org_unit,DC=bz,DC=ad,DC=min,DC=local
  CN=Another_role,OU=some_org_unit,DC=bz,DC=ad,DC=min,DC=local
  CN=Users,OU=Dep,DC=bz,DC=ad,DC=min,DC=local
  '   "rollen" from dual
  ) sessie;

  Returns CN = A_role.
  I want him back all of the CN = concatenated values with a semicolon and stripped of the CN = bit.
  So: A_role; Another_role; Users .
  
  Any help would be much appreciated. Here I use database 11g 11.2.0.2.0.
  
  Does anyone have an idea how to do this in SQL?
  
  best regards Mike

• Insertion and extraction of data from a database by USING SQL Developer al32UTF8

  Hi guys,.
  
  Before I post my questions, I think it's better for me to give you guys my first understandings so that it is easier to understand where / if I have gone wrong...
  
  I use Windows XP and Oracle 10 g
  ------------------------------------------------------------------------------------------------------------------------------------------------------------------
  
  Non-unicode client - a client program that needs to use the code page of the operating system for the mapping of unicode data retrieved from the database as well as the support to display/insert characters from the code page to the database.
  For example sqlplusw.exe
  
  Therefore, when you use a non-unicode client
  
  (1) we define the code page of the OS (Control Panel - regional and language of the parameter - advance - the language for non-unicode programs) to the code page that contain the characters that we will view/insert.
  
  (2) we also defined the NLS_LANG characterset on the character set of code page, that we'll insert so that when we do an insert (for example in thai), oracle will and automatic conversion to Unicode can take place. This is also true when recover us the database unicode data so that the correct character set conversion can take place.
  
  INSERTION OF
  THAI->-> UNICODE conversion
  
  RECOVERY OF
  THAI <-conversion <-UNICODE
  
  I hope that my basic understanding is correct up to this point.
  ---------------------------------------------------------------------------------------------------------------
  
  Unicode client - a client program that supports display/inserting unicode characters without the need to set the code page of the operating system (Control Panel - regional and language setting - control - language for non-unicode programs advance)
  For example isqlplus http or SQL Developer
  
  However,.
  
  (1) there are still set the NLS_LANG so that the correct conversion can take place between the client and the database.
  For example, when the recovery if we set NLS_LANG value ZHS16GBK (Chinese) character and store data in Unicode in the database is for example (THAI), then the conversion would be a mistake.
  It's a supported unicode client, then the NLS_LANG character set should be set to UNICODE as well.
  
  ---------------------------------------------------------------------------------------------------------------------------
  
  Those are my questions
  * Important - please help if you're busy and don't have the time to answer the remaining questions
  
  (* Q1) if I had to use a unicode client, what should I put my character NLS_LANG set?
  AMERICAN_AMERICA. UTF8?
  
  (* T2) where can I put the NLS_LANG information of character in SQL Developer, I know there is a metalink for setting NLS_LANG using isqlplus but I cant seem to google each led for SQL developer.
  
  Q3) is my basic understanding of up to this point? If no, please explain in a term more widespread that I'm really not familiar with character sets code page, unicode and fonts, glyphs...
  
  A unicode client (Q4) didn't need to refer to the OS codepage (regional and language updates), y at - it a code page UNICODE for the customer to refer to, or is there an available window API?
  
  Q5)

  , there are still set the NLS_LANG so that the correct conversion can take place between the customer and the > > database.
  For example, when recovery if we set NLS_LANG value ZHS16GBK (Chinese) character and the data store in > > unicode in the database is for example (THAI), then the conversion would be erroneous.

  I'm just on this point for customer UNICODE supported?
  --------------------------------------------------------------------------------------------------------------------------
  
  Thank you for spending the time to read my questions and I hope to hear soon tips from you guys.
  Million thanks again for sharing.
  
  Best regards
  Noob, but eager to learn

  The requirement to always set NLS_LANG is not true for JDBC, which ignores the NLS_LANG altogether. Java programs extract the textual data in string variables, which uses Unicode UTF-16 by design. JDBC defines the conversion of character sets so that data is converted between UTF - 16 and the database or the national character set.

  The obligation to set NLS_LANG is not generally true for the OIC, either. The first call to a problem of the BEAK may be OCIEnvNlsCreate(). This call has two parameters that allow the caller to set the character set to use for the text of VARCHAR2/TANK/LONG/CLOB/statement and the character set to be used for NCHAR/NVARCHAR2/NCLOB. Only if these character sets is specified as 0, character set NLS_LANG is used. Also, the OIC programs can specify different character for each binding sets or set the variable (i.e. the buffer input/output). Note: The OIC programs always use NLS_LANG to initialize the language settings and the territory for the client program and the database session. Only the character set can be specified is OCIEnvNlsCreate().

  OCIEnvNlsCreate() can specify the client character set to UTF-16 (platform boutien) format. This is not possible with NLS_LANG.

  Various interfaces based on the BEAK, such as ODBC Oracle and .NET for the ODP, explicitly initialize OCI with character set Unicode and therefore ignore the NLS_LANG character set as well.

  Thnx,

• How to extract a string from a varchar column value

• How to return two values of a function?

  Hi all
  I have a function which returns a varchar2 value. This value is used in the SQL of a ref cursor
  
  Now I want this function returns two values. I tried to use varray, but could not accomplish the task.
  
  Can you tell me how can I find the two values from a function? and how this function can be called in a SQL query?
  
  Thank you very much

  The query should look like:

  SELECT v.col.name AS name
       , v.col.flag AS flag
  FROM   ( SELECT kk_test_kk(t.somecolumn,t.someothercolumn,42) AS col
           FROM   sometable t ) v;
  

  Note that you need to prefix with the name of view inline ('v' in the example) and the expression of the function ('col' in the example).

• Synchronize two schemas from database on a linux server using Oracle GoldenGate

  I followed this guide ( http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/goldengate/12c/OGG12c_Installation/index.html?cid=9167 & ssid = 0 ) and for two different databases running on the same instance of database schemas.

  
  What I have now is a Linux server with two Oracle database schemas. I have access through my Linux virtual machine. I want to do the synchronization possible between them.

  I use Oracle GoldenGate to make this possible. What should I do now? Goldengate is must be installed in the server too? I'm totally new to this situation. Can someone give me at least the major steps before going to the more comprehensive study?
