  Hello

  In a relational database, each column of each row needs to store a value, not a repleating group of values, such as a delimited list. It is so basic to the design of database it is called "First Normal Form." You don't have to follow the rules like that, but if you do not, your code will be complicated, inefficient and prone to errors. It might be better to re-design your application so that each value was on a separate line.

  If you can't do that, then you can start by dividing your lists of delimitd in separate lines. Then you can easily fond distinct values and use any technique of chain aggregation to combine the results into an output line.
  Here's a way to do this:

  WITH     got_params     AS
  (
       SELECT     'A,B,C,D,F' AS str, 1 AS str_id     FROM dual     UNION ALL
       SELECT     'C,F,H,B,A,K',          2            FROM dual
  )
  ,     got_part_cnt     AS
  (
       SELECT     str
       ,     1 + LENGTH (str)
              - LENGTH (REPLACE (str, ','))     AS part_cnt
       FROM    got_params
  )
  ,     cntr          AS
  (
       SELECT     LEVEL     AS n
       FROM     (
                SELECT  MAX (part_cnt)     AS max_part_cnt
                FROM    got_part_cnt
            )
       CONNECT BY     LEVEL     <= max_part_cnt
  )
  ,     got_substr     AS
  (
       SELECT DISTINCT
              REGEXP_SUBSTR ( p.str
                             , '[^,]+'
                      , 1
                      , c.n
                      )          AS sub_str
       FROM    got_part_cnt p
       JOIN     cntr          c  ON     c.n     <= p.part_cnt
  )
  ,     got_r_num     AS
  (
       SELECT     sub_str
       ,     ROW_NUMBER () OVER (ORDER BY  sub_str)     AS r_num
       ,     ROWNUM                                        AS r
       FROM     got_substr
  )
  SELECT     MIN ( SUBSTR ( SYS_CONNECT_BY_PATH (sub_str, ',')
                        , 2
                        )
           )          AS unique_sub_strs
  FROM    got_r_num
  WHERE     CONNECT_BY_ISLEAF     = 1
  -- START WITH     r_num     = 1
  CONNECT BY     r_num     = 1 + PRIOR r_num
  ;
  

  It works in 10.2.0.2.0 Oracle Express Edition, which is the only database, can I use it right now. For the main query, you should be able to say:

  SELECT     SUBSTR ( SYS_CONNECT_BY_PATH (sub_str, ',')
              , 2
              )     AS unique_sub_strs
  FROM    got_r_num
  WHERE     CONNECT_BY_ISLEAF     = 1
  START WITH     r_num     = 1
  CONNECT BY     r_num     = 1 + PRIOR r_num
  ;
  

  but, when I try it on my database, I get only "A, B" as output. CONNECT is very buggy in Oracle 10.2; If you have Oracle 10.1, simplest form might work.

  The above query can be shortened, some, but I wrote it this way to make it easier to understand.
  For example, you can combine got_sub_str and got_r_num subqueries. If you do so, substitute DENSE_RANK, ROW_NUMBER.

  This does not imply that the sub-qtrings are all 1 characters long. If they are, the query can be simplified.

• How to run DBMS_SQLTUNE.report_sql_monitor of SQL Developer 4.0

  Hello-

  We have new SQL Developer 4.0 as a single stop for all reports of performance tuning.

  (So far, we know how to generate the AWR and ASH ADDM directly from SQL DEV 4.0 and we can do as a NON-privileged user)

  Now, the question is how to run DBMS_SQLTUNE.report_sql_monitor API SQL DEV 4.0?

  I tried this way:

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  SELECT DBMS_SQLTUNE.report_sql_monitor)

  sql_id = >: SQL_ID

  Type = > 'TEXT ',.

  report_level = > 'ALL') AS myreport

  DOUBLE;

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  and then right button click of the mouse on the line "myreport" and the EXPORT of 'text' in the menu drop down and save in the. FichierTSV on the local file system.

  It works this way, as expected, but seems to be a lot of hassle: too many steps.

  Then I tried the HTML format:

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  SELECT DBMS_SQLTUNE.report_sql_monitor)

  sql_id = >: SQL_ID

  Type = > 'HTML. "

  report_level = > 'ALL') AS myreport

  DOUBLE;

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  and it didn't work well at all SQL dev 4.0

  Any help will be greatly appreciated.

  (once again, the idea here is to set up our development and QA groups with full access to performance all reports without having them call DBA for help in the production of any SQL tuning report).

  Thank you

  VR

  There is certainly a 'room' to improve the interface, just tell me what you would like to be like him. For example, you want an overview of the SGS of all SQLIDs running on the nodes you could then select this option to run a report for? Don't say it is what we would do, but I was wondering what it is that you ask for.

  The listed application is good, but does not limit the output of your session - it should return data from all sessions.

  You must add an AND condition in the WHERE clause to limit your session. You can try this (untested)

   where audsid=(select userenv('sessionid') from dual);
  

  You can also perform a SQL trace and tkprof to obtain data to SQL executed the trace start and end of the trace.

  I'm new to OFA. I have a requirement on a Page of the OAF that when a new record is created system must check whether the same value already exists in one of our custom paintings, then it should trigger a warning.

  context of the page get the value of the code and action.

  String codeValue = pageContext.getParameter ('Code');

  String actionValue = pageContext.getParameter ("Action");

  String stdSeqNumValue = pageContext.getParameter ("PacelineStdSeqNum");

  declare the variable to count the number of records returned by the query.

  int result = 0;

  get the JDBC connection.

• How to read the BIT of SQL Server value in CVI

  Hello

  I try to get a value of SQL Server 2005 (ture or false) bit in CVI (with SQL toolkit). I use the DBBindInt, but overall the return value is - 1.

  How can I get the real value of SQL?

  Thanks for your help

  Region

  Do you mean that you never receive the value FALSE, IE 0? Or you expect a TRUE value to be exactly 1? It is very common for TRUE to be represented as -1; If you are concerned just hide all the bits in the value returned with the exception of bit 0 - this will then give your alternative 0/1.
