• delete all the records in a table, the speed of insertion is not change.

  I have an empty table, and I insert a record need 100ms.
  During this table a 40,0000 trace, I insert a record need 1 s, it's ok, because I need to make a comparison according to an index before inserting a record need, so more record, more time.
  The problem is when I delete all the record in this table, the insertion time is always 1s, not reduce to 100ms. Why?

  Hello

  Read this part of the oracle documentation

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/logical.htm#CNCPT004

  The reason is always 1s, because when you inserted 400ko record as HWM (high tide is the border between old and new space in a segment.) moved to the top. And when you remove all records of your HWM still in the same coordinate system and that you have not reset to 0. So when you insert 1 it save free space and after finding faces (usually a regular insertions got 6 steps it inserts data). If you truncate your table you and try it again it will be faster that your HWM is reset to 0.

  Thanks for the request

  The query does not work with the following documents

  insert into test_dep
  select 16,'AS',750664,'PG',750758 FROM dual 
  
  insert into test_prs
  select 4,750758,750668 from dual
  

  the r_id should not be put in correspondence with the columns in the test_dep table. P_id must only be put in correspondence

  OK, you want to match against the de_id and the de_u_id p_id? Or a line where either p_id concordances r_id de_u_id or de_id must not be returned?

  To match p_id against de_id and de_u_id, you can write the query like this:

  select id, p_id, r_id from test_prs where
  p_id in
  (select p_id from test_prs
  minus
  select de_id from test_dep
  minus
  select de_u_id from test_dep);

• Comments of the column when the description (desc), one table

  Hello. Is any way to associate a comment with a table column that appear during the description (Desc), one table? I added a column to a table, and I'm almost certain the wire while it will become clear what this column contains exactly. I hope there is a way to add a comment or a Description of a column in my table.
  
  Any help would be greatly appreciated.

  You can use the

  comment on [table].[column] is 'some text here';
  

  command.

  However the DESCRIBE of sqlplus command appears not only. You will need to write your own table-description using USER_TABLES and USER_TAB_COLUMNS USER_COL_COMMENTS report query.

• Transpose the text column of the Oracle using ODI table

  Here's what I'm trying to do:
  Source table that contains the columns:
  Time, Blob, Item-ID
  
  The expected target has the columns:
  Time, data, Item1, Item2. ItemN
  
  1. where Item1, Item2 are as shown: say for example the source table has 10 rows of different IDS, there are 10 columns in the table target from Item1 to article 10. (Assuming that no. different IDs are fixed)
  How to do this? I learn ODI for a few weeks now. Understand the basics and terminology, I don't know how to do this.
  
  2 data (the target table) is a return value from a stored procedure that would transform the Blob (of the Source table)
  The stored procedure is ready, but how do you use the procedure to get the target to the source.
  
  Any help/direction would be greatly helpful.

  1. a question: How do you who would determine row goes to which column? You can say that the 1st line value becomes item1, but without a rank ORDER 1 will always random. If you have a way to ensure the order of the rows (say, a column that can store the rownum) then what you need is in the interface, you specify for n - th element mapping must be MAX (Case when n = rownum then point else ' ' end). Who should take care of it.

  2. There is a way to do this in ODI. Because you are a beginner, I would recommend that you create a temporary table and you use a PL/SQL block to generate data of BLOB and serve another table of the source that can update the column of data in the temporary table target table.

  Can you share the code? This seems to be the opposite of what JPA or any ORM package is intended; you would usually the ORM package produce SQL statements based on an object model and a query of high level object, but you try here to feed a sort of a pre-existing query object model. As I said - back. You may want to use executeNativeQuery?

  Whenever I am confronted with a situation where a request starts to do involving the unions, subqueries, etc.. I keep the side JPA as stupid as possible. I create a view on the side of the database and that you simply map my entity to this point of view. With appropriate indexing in place which usually performs very well.

• Validation form column against the value of another Table

  Hello

  I'm new to this forum, so please bear with me a bit!  I only have a small amount of writing PL/SQL experience, and I've never written Javascript or JQuery before.  I am an Oracle DBA and I coding experience C and PERL, so I have a strong technical background.  But I need some advice on the best way to approach a problem.

  I have an application of data base in Oracle Apex (version 4.2) with a tabular form on a table: Let's say that #1 with the conditions of licence 1 a, 1 b, and1C.  I have to make sure that the value entered in col B is not greater than the value of a column in another table (for example table #2 pass 2 (a).  From a conceptual point of view, the amount of money available is in the #2 table, and my tabular form lines are an act of spending money (such as orders or invoices), so I have to make sure that we spend more that we have.  Who is?

  Does anyone have tips for the best way to do it?  I'm figuring that the biggest problem here is perhaps to account for people who enter multiple lines in the form of tables at the same time, right?  So, if a person is entered 3/invoices, I need a total to ensure that they do not have spend more than we have in the #2 table.

  I really appreciate your help!

  Best regards

  Laurie Baublitz

  Ah, I was not totally with you on this charge then. My validation works overall, but it totals the amount for each line, regardless of the task. Okay - who was not totally my solution but more a demonstration of the technique that you can use to validate your tabular presentation in this way.

  You could solve this issue with a safe collection, or with a table plsql where you add an entry for each task name and keep the amount stored in there.

  Anyway, it would be better for you to spend a little time on playback on the plsql collections or collections apex!

  • 5 use PL/SQL of Collections and records
  • APEX_COLLECTION

        t_taskamount(l_task) := t_taskamount(l_task) + l_amount;

      -- it's not the best idea to perform a select each time and could be

• need help to correct the records in a table

  Hi all
  
  I loaded a content file in a single table with a single column, the file is to have the data as below
  

  Record 1.  ABC|AVC1|1234|
                 xyz|abc
  Record 2.  ABC1|AVC1|12334|
                 xyz
                 |ABC
  Record 3. ABC1|AVC1|12334|xyz|ABC

  I need to correct the data in the table above, the 3 reviews. is the correct format I need record1 and record2 look like.
  
  Note Record1... 3. the text above, I've added. (it's just a real example table a 5million rec)
  
  Can any of you help me correct this file using plsql query or sql by creating another table which has corrected data
  
  Logical I think is
  
  All records must have 4 delimiter if less then wear the next record in the line to the previous line for example
  
  Record 1. ABC | AVC1 | 1234 | XYZ | ABC
  
  Even if there is no delimiter on line then also make the next record in the line to the previous line for example
  
  Record 2. ABC1. AVC1 | 12334 | XYZ
  | ABC
  
  
  Like wise cleaning the table and placing it in a new table, to export.
  
  Oracle version I have is 10g
  
  
  Kind regards

  This is because you have not changed the subquery factoring section (aka the WITH clause) properly (I suggest that you are looking for this - it's a very useful piece of syntax to have under your belt). You must change as follows:

  with res as (select rn,
                      txt,
                      ceil(sum(length(txt) - length(replace(txt, '|'))) over (order by rn)/4) grp
               from   t), -- assuming that your table is called t.
     final as (select replace(sys_connect_by_path(txt, '$'), '$') full_txt,
                      level
               from   res
               WHERE CONNECT_BY_ISLEAF = 1
               connect by grp = prior grp
               and        rn = prior rn + 1)
  select case when length(full_txt) - length(replace(full_txt, '|')) = 4 then full_txt end full_txt
  from   final
  where  case when length(full_txt) - length(replace(full_txt, '|')) = 4 then full_txt end is not null;
  

  ETA: where 4 appears in my query, you will need to change the number of pipes in your line.
  ETA2: and I suspect that you need to change the 5 in the BluShadow query to 1 + the number of pipes in your line.

• Update trigger that inserts the record in another table

  I searched the forum and the web for an example like this and I can not find a:
  
  A field is updated in the TABLE_A and it triggers a single record TABLE_B insert that has the old and the new value of the field.
  
  I write a lot of complex data warehouse SQL-based reports, but very rarely do much PL/SQL, any help would be appreciated.
  Thanks in advance.

  Hello

  You can specify that the trigger should fire only when certain columns are referenced, like this:

  create or replace trigger test_fund_trig
  before update OF FUNDING
  on table_a
  ...
  

  If you do this, the trigger will not draw on statements such as:

  UPDATE  table_a
  SET     mod_date = SYSDATE;
  

  You should always use an IF statement, as I mentioned earlier, if you do not want to follow the updates where the value of this column has not really changed.

• Column of the row on a table (using the SQL query)

  Data in my table looks like this.

  COL_1, COL_2

  ----------    ----------

  1 ABCD

  2 ABC

  3 ABCDE

  Now, he must, for the entire line, length COL_2 text exceeds 3, display the text remaining in the new line. For example, the first row (COL_1 = 1), COL_2 length is 4, so in SQL output two lines will be displayed as shown below. Also, the last row (COL_1 = 5), the length is 8, then, in SQL, output 3 lines will be displayed as below. And for the COL_1 = 2 & 4, only 1 rank will be displayed as the text COL_2 length is less than or equal to 3.
