• Need for clarification to varchar2 column

  I get xml that will be inserted in the local table messages
  It is, I don't really know the size of the incoming xml message data.
  Design of the structure of the table is now difficult.
  If I design the column in the table for column varchar2 with VARCHAR2 (4000) and if the message contains the value
  as 'SAM', 'GEORGE' (no more than 10 characters) then it does not seem good for the VARCHAR2 COLUMN (4000)
  Oracle does not create the table with VARCHAR2 (without specifying the size)

  Any suggestions?

  S

  There's no real difference if you use varchar2 (4000) or varchar2 (100). Apart from the obvious that you can store up to 4000 bytes, against only 100/characters multibyte.

  However, there are a few minor side effects. Few of them and a comparison of the performance is described here: http://arjudba.blogspot.de/2009/08/does-oversize-of-datatype-varchar2.html

  (1) the varchar2 column indexing 4000 could be a problem (the ora-01450 exceeded max key length).

  (2) the size of the table could be actually smaller for tables with many sparesly populated varchar2 4000 columns. I can't find the source for that at the moment, but it had to do with the way oracle reserves future space required for the column.

  (3) migration of rank is more likely to happen if the great texts are added (= update) later.

  (4) If you define a variable with % rowtype in the table, it will use more expensive space PGA

  (5) some tools like TOAD could get questions or need of more resources to operate on 4 k columns.

  TIMESTAMP is not time column. Look at him as a date with a better accuracy - it supports the franctional part of a second. In any case, use:

  Select to_timestamp (date, "DD/MM/YYYY HH: mi AM'") twice;

• VARCHAR2 columns stored as anything other than letters

  Hey guys out there.
  I use Oracle Forms, but I need to know all the columns in a table (columns VARCHAR2) that have data that was not saved as uppercase. That is why I posted my question here and not in the forms. Any help would be great. The shape, that I'm looking tables and many albums and a lot of VARCHAR2 columns :-)
  
  I looked at the description of all_tab_columns but I doubt that could give me the information I'm looking for.
  
  Thank you

  There is no data dictionary attribute that indicates if the column given tiny inside. So the only option would be to check each column.

  Of course, you could write a bit of dynamic SQL to do this

  DECLARE
    l_sql_stmt varchar2(32000);
    l_cnt pls_integer;
  BEGIN
    FOR x IN (SELECT * FROM all_tab_columns WHERE data_type = 'VARCHAR2')
    LOOP
      l_sql_stmt := 'SELECT COUNT(*) FROM ' || x.owner || '.' || x.table_name || ' WHERE ' || x.column_name || ' != upper(' || x.column_name || ')';
      EXECUTE IMMEDIATE l_sql_stmt INTO l_cnt;
      IF( l_cnt > 0 )
      THEN
        <>
      END IF;
    END LOOP;
  END;
  

  This is going to be rather ineffective, however, particularly if the tables are large.

• Can we do Union between 2 fields in OBIEE formula column?

  Hello gurus,
  
  Can we do the union between 2 fields and calculate a column that in the criteria of the obiee report?

  Vieira says:
  Hey David,

  I m using the same method to evaulte year and MOnthname

  Year: YEAR (CURRENT_DATE)

  Name of the month: MONTHNAME (TIMESTAMPADD (SQL_TSI_MONTH-1, CURRENT_DATE))

  but I want both values in unique colmun...
  Because I have to create a report that runs to the year and last month both at the same time.
  so once I have it calculate such doin union between YEAR and MONTHNAME column, I'll use the PivotTable to create this report...
  So basically I want a column that has the CURRENT YEAR, LAST MONTHNAME as list of values. and that's the reason why I want the union in the formula in the column...

  Let me know if you need more information...

  OK, got it.

  So follow these steps:

  (1) in your first report, put your attribute columns and measure your column a dummy column.

  (2) place a filter on the column "equal to / in".

  MONTH = MONTH (table.date) (TIMESTAMPADD (SQL_TSI_MONTH-1, CURRENT_DATE))

  (3) in the fx of the dummy column, delete content and enter 'Previous month' and name the 'Date Range' column (or whatever you want).

  This will generate a report where the measure is for the previous month.

  (4) in your second report, put the same attribute columns and measure your column a dummy column.

  (5) place a filter on the column "equal to / in".

  Year (table.date) = YEAR (CURRENT_DATE)

  (6) in the fx of the dummy column, delete the content and enter "current Year-to-Date" and name the 'Date Range' column (or what you want).

  This will generate a report where the measure is for the current year.

  (7) combine queries into a UNION.

  The synthesis report will have the values "previous month" and "current year-to-date" in the same column you want.

  (8) in your PivotTable, put the attribute columns in the Section of lines, as in measures Section and the 'Date Range' column in the columns Section.

  That should do it.

• OBIEE 11 g: variable presentation use in the column header

  Hello world
  
  I was playing around with app sample dashboards and I saw a prompt of dashboard that they turned into a column selector. I liked and it reproduced in my own sandbox.
  
  I love the results, however, I would also like to change the column heading to indicate clearly how much has been selected. It's pretty clear when you're looking in the dashboard, but once you export the data, it can be confusing to what extent has been selected.
  
  This is why I would like to use a variable of presentation in the column header section. I tried to do, but he he interpreted as a literal instead of evaluation of the declaration.
  
  Is there anyway to get a variable in the column header?
  
  Thank you!

  Hello

  Take a look at the following links:

  http://oraclebizint.WordPress.com/2008/01/25/Oracle-BI-EE-101332-dynamic-column-headers-using-presentation-variables-sets-and-conditional-formatting/

  display the variable of presentation on the table column header

  Set the presentation variable in the column header

  It will be useful.

• the list of columns separated by commas of a dictionary table table

  I use the following question.
  
  CONNECT_BY_ROOT SELECT table_name TopLevel, level,
  connect_by_isleaf IS_Node_leaf,
  substr (SYS_CONNECT_BY_PATH (column_name, ','), 2) column_name
  Of all_tab_cols
  where connect_by_isleaf = 1
  and column_id < (select max (column_id) + 1 all_tab_cols
  where table_name = 'Table_test')
  and column_id > (select min (column_id) - all_tab_cols 1
  where table_name = 'Table_test')
  START WITH table_name = "Table_test."
  CONNECT BY PRIOR column_id = nocycle (column_id - 1).
  AND table_name = "Table_test."
  
  The only problem with this query is that it goes into infinite loop. Can someone suggest a better solution?

  Why you ask all_tab_cols, I think will realize you that it will pull all tables in your database.

  If you want to retrieve the name of the table and the columns (separated by commas) your schema, you must query user_tab_cols.

  and here is the sql code

  select table_name,ltrim(sys_Connect_by_path(column_name,','),',') column_names
  from
  (select table_name,column_name,row_number() over (partition by table_name order by column_id) rn
  from user_tab_cols)
  where connect_by_isleaf = 1
  start with rn=1
  connect by prior rn=rn-1 and prior table_name = table_name
  /
  

  Or, you can use all_tab_cols to query a specific table by passing the name of the table and the name of the owner

• Changing a varchar2 column (11) to varchar2 (15)

  Hello
  
  I have a table of 600GO containing nearly 200 columns. This picture is obviously not truncated, it is a table partitioned and sous-partitionnée. I have a varchar2 column I need to increase the length. This table is in a production database and so I don't have TO run any risk with him even if I have to find a way to increase the size of the relevant column. Let's say that the table name is XLARGE_TABLE and the column I need to edit is called FIRST_COLUMN. I would like to know the safety and execution of the execution of the following simple ALTER statement:
  
  ALTER TABLE XLARGE_TABLE CHANGE FIRST_COLUMN varchar2 (15).
  
  NOTE: FIRST_COLUMN is filled throughout with millions of rows table.
  
  Thank you very much for your attention to help me in this regard.

• Select the value of the field in the database column stores xml as a varchar

  Hi all

  Oracle version is 11 GR 2.

  I have a column of a database in which we store the XML string varchar2.

  In this case my answer would be - maker16

  select extractvalue(datacolumn,'/changeinfo/property name[@property name="modifiedBy"]/newvalue') from t;
  
  

  How to write a select statement to get the above result?

  Thank you

  SID

  You can do it like

  1. get the name and NewValue as columns and then create a filter with the WHERE clause.

  2. or you can filter when you set the path itself.

  --I have not applied the WHERE clause to filter the NAME. You can do that.

• Organize PDF fields to populate the columns in the order in Excel

  I created a PDF form to transfer customer data received by the *.xml format, but the headers of the columns (field names) and data (field entries) fill on the same line in Excel.  Is there a way to define a the names of the fields to fill in a specific order in the first line and field entries to fill in the second row?  If not, is there a simple function to rearrange the data in Excel?

  Any help would be greatly appreciated.

  If you export data to a text file, it will be a file delimited by tabs that you can open in Excel with the field names in the first row and their values in the second.

  If you want to customize the order of the fields, you must use a script, however.
