• How to find the name of the Oracle database server?

  People,

  Hello. I installed Oracle Database 11 g 2 OS Oracle Linux 5. The installed directory is/home/user/OracleDB_Home and/home/user/OracleDB_Base.

  Host name is "mylinux". Name of the database instance is PT853.

  I use "mylinux" as the name of the database server, it does not work. I use another way to do as below:

  Export ORACLE_HOME = / home/user/OracleDB_Home

  Can I use "mylinux ORACLE_HOME" as the name of the database server, it does not work either.

  
  My question is:

  How to find the name of the database server Oracle with Oracle Linux 5 OS?

  
  Thank you.

  You must learn the basic of database Oracle.

  Please don't regard it not same as SQL server in terms of configuration.

  You never specify the database server name in Oracle.

  You specify the host name in only two places, 1) Tnsnames.ora/JDBC/ODBC (or any client you want to connect) and listener.ora) 2.

  There was nothing called specify the name of the Oracle database from an oracle database server.

  Hello francy77

  In fact, it is not possible. There is a SQL "soundex" function, which "returns a string containing the phonetic representation of the char . This function allows you to compare the words that are spelled differently, but sound as well in English. »

  Example: Smith could be written as "SMYTHE".

  Try this:

  SELECT first_name

  FROM (SELECT 'Smith' AS the name OF DOUBLE UNION ALL

  SELECT 'Sophie' AS the name OF THE DOUBLE)

  WHERE SOUNDEX (first_name) = SOUNDEX ('Smythe')

  ;

  You get two records...

  But if you have a specific logic, then you must create a function and he set what text - what you want text input.

  Is it useful or the solution for you?

• How to find the name of the image in E10?

  Hi all

  This may be a simple question, but the question in the moment: is there a way to tell what image name is E10? I have an email with two images that I can't find the names. I tried hover, right-click, looking for a possible name, etc, nothing works! I believe in E9, you could just look at the details of the image, or open the HTML, y at - it something like this in E10? HTML is not an option, as this was built using the e-mail writer.

  Thank you very much!

  Hi Hayley,

  The best way to find the name of an image that was inserted in an email is to send a test e-mail. Upon receipt of the email, use the "Open web version" link to open the email in your browser. Once opened in your browser, right click on the email address and select the "View Page Source" option, this will display the HTML for email. If you follow the natural progression of the email from top to bottom, in among all the content text and code, you should be able to find the names of the image. They will look something like this http://images.response. "/ EloquaImages/clients***/{b823ae52-fb21-4532-882f-b1f4e9cb423b}_facebook.png" width = "27" height = "26" alt = "Facebook" > where facebook.png is the name of the image.

  I hope this helps.

• With CVI SQL Toolkit, how to add the new variable param column in a table.

  Dear all:

  I used the CVI Sql toolkit to create a database, but now I don't know how to add a new column to a table in variable param.

  I know, to add a column with the name of constant column could be down by below:

  DBImmediateSQL ((hdbc, "alter table table1 add column1 char [100]");

  But if Column1 is a param variablae how can I write the code? Please advise?  It will be appreciated if you could give me an example.

  Best regards!

  HI -.

  If you look at the parameters that you pass to the SQL function, you can see that the second parameter is a string constant. In your code, you can create an array of characters (string). You can then use sprintf to programmatically determine what will be the contents of this variable. In the function call, you can put the variable instead of the literal string, and you will have a customizable SQL statement.

  Hope this helps-

• How to set the value of a column in a table according to another column?

  Hello world!
  
  I use Apex 4.1.
  My question is how can I set the value of a column in a table according to another column?
  I have a table and when I insert the value in the column content, I want to change this value in the note column with the note, which is generated with pl/sql function (function of string returned if the typed value is in the range).
  
  I tried to use javascript as

   $('input[name=f02]').live('change', function(){
  if($(this).val()!='1'){
  $('input[name=f03]').val("test")}
  }); 

  for the development of the column note to test if the value typed in the content of the column is not 1, but this code assigns the value to all the lines and I need to set only the specified line.
  
  Can someone give me a hint in any way to do this if possible?
  
  Kind regards

  You will need create a process on your page type PLSQL and develop this process "we demand" of the page. In this process, you can run the PLSQL you need. That is to say to retrieve the note value as described in your PC:

  and when I insert the value in the column content, I want to change this value in the note column with the note, which is generated with pl/sql function (function of string returned if the typed value is in the range).

  In this process, you must provide a return value of the call, and you can do this by using htp.p. Example:

  DECLARE
     --putting x01 in a var to simplify
     l_test_var VARCHAR2(200) := apex_application.g_x01;
     l_return VARCHAR2(200);
  BEGIN
     -- a simplistic test
     IF LENGTH(l_test_var) BETWEEN 10 AND 20 THEN
        l_return := 'String is between 10 and 20';
     END IF;
  
     --this will write l_return to the buffer, and the ajax callback will receive this
     htp.p(l_return);
  END;
  

  And the code that I wrote above, which is javascript, would need to go where your current code is that binds to the onchange event. The result should be that, when a change is made to this element, an ajax request is made on the server. When the call is finished, it will be the value returned in the item you want.

  PL/SQL: digital or value error: NULL index key value table

  What happens if the PL/SQL table has NULL values. Question is how you want to handle NULL values. You want to ignore nulls as GROUP BY do? If you want to consider NULL values, you can say if you want to order the NULLS FIRST or NULLS LAST. I guess that logical GROUP BY:

• ORA-01438: how to find the name of the column?

  Hello
  
  I'm trying to find the column which is causing ORA-01438 when inserting into a table.
  
  The insertion is made by a C program that reads from a socket and written in an oracle 10 g database using Oracle Pro * C.
  
  I tried to identify the column by printing the values (about 250) just before the insert statement is executed, but check these values has been a task heavy and error prone and did not help to correct the mistake (I found a bunch of values which out of reach, but changing these values has not resolved the issue).
  
  Abandon this idea, I tried to track the session to help
  (1) DBMS_SYSTEM. SET_SQL_TRACE_IN_SESSION,
  (2) DBMS_MONITOR.session_trace_enable/disable and still
  (3) change the context name system set events 10046 trace forever, level 12' and;
  (4) alter system set sql_trace = true scope = mΘmoire;
  
  DBMS_MONITOR.session_trace_enable only gave me a few tips (the insert statement) in a trace file. But it worked for a simple example of a test database.
  
  When I try to turn on tracing on the database, where the error occurs, then I'm still not able to set SQL_TRACE in V$ SESSION true, even if no error is returned by the statement "DBMS_MONITOR.session_trace_enable". The value of SQL_TRACE in V$ SESSION does not change and I have no idea why. On the test database, it works fine and I can find the trace file in the user_dump_destination directory.
  
  Anyone have any suggestions on how to fix this?
  
  Any help is appreciated.
  Thanks in advance!

• How to find the name of the table where the paricular column is common to all the tables...

  Hi all
  
  any help please...
  
  I have a lot of tables in the diagram
  
  Select * from tab; show all tables...
  
  Now, there is a single table called has columns as name like this, dept, empno, joindate, sal...
  now the description column in table present in so many other tables in the schema above...
  
  How can I know the names of tables where this 'Description' column shows.
  
  Note: I use the 10 g version and I do not have DBA privilege on the diagram...
  
  Thanks in advance
  ASP.

  Are you logged in as owner of these tables? Otherwise (and it seems that you're not), you have privileges on these table? If you do, use:

  SELECT  OWNER,
          TABLE_NAME
    FROM  ALL_TAB_COLUMNS
    WHERE COLUMN_NAME = 'DESIGNATION'
  / 
  

  If you don't have privileges, but you can choose from DBA_TAB_COLUMNS, use:

  SELECT  OWNER,
          TABLE_NAME
    FROM  DBA_TAB_COLUMNS
    WHERE COLUMN_NAME = 'DESIGNATION'
  / 
  

  Otherwise ask your DBA to run it.

  thanx

  AFAIK, you must query dba_audit_session to see who connected to the database. Dba_audit_trail contains all the audit records, we cannot know if the records that show you are records of connection.
