  Thank you very much!

  Someone better than me can probably provide some ideas on exactly how to analyze the current value of VARCHAR_DATE

  The fact is that any analysis fails for a date like 10/11/12.
  You have only one chance if you know for sure that the order of the months of the year and the day is always the same. otherwise you can only guess.

  If guess is good enough depends on the importance of the process of using it for the success of your business...

• help me create a column with the time format

  Hi all
  
  Please help me find the query to create a table with 3 columns and insert the following data
  
  ENTITYID | CHGDATE | CHGTIME
  
  ======= ==================== ========
  
  4214984 | 2 OCTOBER 06 12.00.00.000000 AM | 07:23:57
  
  4214985 | 12.00.00.000000 11-SEP-08 AM | 10:52:19
  
  and update of the first line of the above table as follows
  ---------------------
  4214984 | 2 OCTOBER 06 07.23.57.000000 AM | 07:23:57
  ------------------------
  you will need to update the CHGDATE column with the time of the CHGTIME column.

  Sorry, we need a new format around the to_date

  select to_date(to_char(chgdate, 'mm/dd/yyyy') || ' ' || to_char(chgtime, 'hh24:mi:ss'), 'mm/dd/yyyy hh24:mi:ss') from etime3;
  

  This should telll Oracle to the format of the generated string. If this isn't the case, run select with the to_char two as separate columns to see that get us the data that we expect.

• [8i & 10g XE] How to compare a column with the text of a column with numbers

  This is probably a simple question, but I can't seem to find the answer. I tried variations on use to_number to_char and interpreters, all nothing will do.
  
  The real problem is that I have a table with a column of numbers in a database 8i (datatype = NUMBER (3)) and a column with the text (datatype = CHAR (3)), and I need to compare two values.
  
  This table has thousands of lines, but here's an example of the data in these two columns:

  TXT     CHR
  -----------
  001     1
  001     2
  002     2
  XXX     1
  003     3

  What I want to do is select the lines where the TXT and CHR VALUES do not match, then it would be (given my example):

  TXT     CHR
  -----------
  001     2
  XXX     1

  But, I'm having difficulties in comparing two columns, because they are not the same type of data.
  
  I tried to work on a simplified version of the problem in the 8i database both my 10g XE database:

  SELECT     *
  FROM     (
       SELECT     1.000               AS nbr
       ,     TO_CHAR(1.000,'000')     AS txt
       ,     CAST('001' AS CHAR(3))     AS chr
       FROM     dual
       )
  WHERE     txt = chr
  ;

  But this also returns any line, and it isn't even the "XXX" in the text column to treat in this example.
  
  Can someone help me understand what it is that I'm missing?
  
  Thank you!

       FROM     dual
       )
  WHERE     txt = chr
  ;
  

  Try:

  TO_CHAR (1.000, 'FM000')
  

  By default, TO_CHAR leaves place the beginning of the string to a sign less, in which case he should ever one, TO_CHAR (1,000, '000') returns makes 4 characters, not 3. "FM" in the format said TO_CHAR do not add a space.

  If it does not, after the release of DUMP (txt) for the few lines that you can't match, so that we can see exactly what is in them.

• Documentation about adding column with the DEFAULT value.

  Hello
  
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241
  
  < quote >
  If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
  < quote >
  
  I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.
  
  According to the documents of 11 g
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105
  
  n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.
  
  This insistence is intended? If not, IMO, it should be changed.
  
  Kind regards

  Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

  When you add a column, the initial value of each row in the new column is null.

  * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

  This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

  * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

  Hope that helps to clarify the matter further.

  Kind regards

• Querying the oracle table that has a column with the name of "FILE".

  Hi all

  I need to have an oracle table that has the column with the name "FILE".

  I can query all columns with the query "select * from table".

  But I'm not able to use the query "select the table file.

  This table is converted from ms access to oracle and I need to have this column with the name "FILE".

  Any suggestions?

  Hello

  FILE is a keyword from Oracle, so it's not a good name,

  Use FILEDATE, or DATE_FILED, or something else that is not in V$ RESERVED_WORDS. KEYWORD as the name column.

  If you need to use the FILE, then you must use quotation marks.

• column with the only format of loading time

  My DB, 11 2 on OEL 5.5 GR
  Hi all
  I have a problem with the loading of the external table. I have a txt file with a format of columns HH24:MI:SS

  START_TIME
  00:10:20
  01:15:11
  02:11:10

  And I don't know which data type use in external table because in the future, I'll have to do some calculations on this column, so I should load as a DATE, but miss me "mm/dd/yy" to the front. Any suggestion how to do properly?

  You could use a data type CHAR or date for the outer table and do your math with this column correctly.

  The key is that convert a time string to a date data type will add the current date to it. For example:

  SQL> alter session set nls_date_format='dd/mm/yyyy hh24:mi:ss';
  
  Session altered.
  
  SQL> select to_date('00:10:20', 'hh24:mi:ss') from dual;
  
  TO_DATE('00:10:20',
  -------------------
  01/02/2011 00:10:20
  

  Some examples of code for both cases, by using the DATE and CHAR data type. I tested it on 11.2.0.1:

  CREATE OR REPLACE DIRECTORY ext_tab_dir AS '/tmp';
  
  -- /tmp/info.txt
  1,00:10:20
  2,01:15:11
  3,02:11:10
  
  alter session set nls_date_format='dd/mm/yyyy hh24:mi:ss';
  

  (1) using the DATE data type

  drop table tab_time_date;
  
  CREATE TABLE tab_time_date (
    key VARCHAR2(5),
    start_time date)
    ORGANIZATION EXTERNAL (

         )
        )

• Insert/update the column with the clob data type

  Hi all

  ORCL Version: 11g.

  I have a table with the clob data type.

  Test12

  (col1 clob);

  I'm trying to insert/update to update the column with more than 4000 characters.

  But due to the limitation of tank 4000, I could not Insert/Update.

  Need your help in resolving this issue.

  THX

  Rod.

  The limit of 4000 characters is incorrect.  That pertains only to the varchar2 data type.  A clob can hold more than 4 G.

  Here is an example that shows how to insert it, I found...

  Otherwise, here is a way 'dirty' to do.

  insert into your_table (COLA, COLB)

  values

  (PRIMARY_KEY, PART 1 OF DATA)

  ;

  Update your_table

  Define COLB = COLB | PART 2 OF BIG DATA

  where COLA = PRIMARY_KEY;

  Update your_table

  Define COLB = COLB | PART 3 OF BIG DATA

  where COLA = PRIMARY_KEY;

  .. and so on...

  I don't know that I personally recommend the second style...  But he could do the job.

• Format of column with the percent sign (%)

  Y at - it shaped the column put percent signs (%)?
  
  Currently, one of the fields in the report shows a number, for example "3.75", but we must add the percent (%) sign, for example "3.75%".
  
  I found the following:
  * To view '$5 234,10', I use "FML999G999G999G999G990D00", these formats with a dollar sign ($) and two decimal places.
  * To display "-5,234.10", I can use "S999G999G999G999G990D00", these formats with the sign (+) or (-) and two decimal places.
  
  However, I can't find how to add the percent (%) sign...

• update of NULL in the column with the values of the adjacent column

  Examples of data

  union all
  select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual)

  This is one of those cases, the case may be where any value of a column can be null

  or two similar columns can be null. If the column is null then I want to update the adjacent column

  average value of the column, if the first column is null so I want to take the next non-null column and update, if the last column is null

  so I want to take prev not zero column and to update.

  In this case would be my expected output

  Any data type, this column is or what are the values it contains, as long as you can derive from the order of the rows of values in the column.  (Of course, the values can be consecutive integers, only they do not have to be).  If you do not have this type of column, you don't have any order to your lines, and what you request is impossible.

  Since you have a load_order column, here's a way to get the results you requested:

  MERGE INTO dst t2

  WITH THE HELP OF)

  WITH got_grp AS

  (

  SELECT load_order

  paramlocation

  paramtype

  ROW_NUMBER () OVER (ORDER BY load_order)

  -ROW_NUMBER () OVER (PARTITION BY CASE

  THEN 0

  END

  ORDER BY load_order

  ) AS the grp

  THE t2

  SELECT load_order
