• conversion of the date string

  Hello
  
  I've recently become involved with databases, and I hit a little snag.
  I have strings that represent a date, they are very oddly formatted and need to store them as dates. the format string looks like this:
  
  "Monday, May 13, 2001"
  
  How can I effectively convert DATE type?
  I hope it's more simple I think.
  Thanks in advance

  /* Formatted on 2012/06/26 04:31 (Formatter Plus v4.8.8) */
  SELECT TO_DATE (REGEXP_REPLACE ('SUNDAY,May the 13th of 2001', 'the|th|of',
                                  ''),
                  'DAY,MONTH DD RRRR'
                 )

• problem with implicit to the conversion of the date in oracle

  Next date functions will work fine as long as string confirms for the next model of the date
  
  D MY separator2 R separator1
  
  the separator can be any sign of punctuation (/ $ % & *, ^) sapces, tabs...
  
  as
  Select ADD_MONTHS('21$MAY*2010',2) from DUAL;
  
  SELECT MONTHS_BETWEEN (23 ^ FEB & 2010', ' 11% jan(2011') FROM DUAL;)
  
  the two works perfectly, but it does not work in the ROUND functions (date) and TRUNC (date);
  
  SELECT ROUND('12-FEB-2010') FROM DUAL; -gives error
  
  It needs explicit conversion using TO_DATE();
  
  My question is why what is happening?
  Is it because we have two functions ROUND (NUMBER) and ROUND (DATE)?

  All of the built-in functions will work fine as long as use you them as directed; in particular, pass arguments that have the correct data type. If a function requires a DATE for an argument, always place a DATE, not a VARCHAR2 you hope will be be implicitly converted to DATE.

  D MY separator2 R separator1

  the separator can be any sign of punctuation (/ $ % & *, ^) sapces, tabs...

  This applies to explicitly call the functions where a format string is used, for example, TO_DATE.

  as
  Select ADD_MONTHS('21$MAY*2010',2) from DUAL;

  SELECT MONTHS_BETWEEN ('23 ^ FEB & 2010', ' 11% jan(2011') FROM DUAL;)

  the two works perfectly,

  As the respondent previous said, the two work may , depends on several factors, such as your NLS parameters. It's a very bad habit to rely on such things. The 1st argument to ADD_MONTHS and two arguments to MONTHS_BETWEEN, are supposed to be DATEs, so always call these functions with the DATEs.

  but this does not work in the ROUND functions (date) and TRUNC (date);
  SELECT ROUND('12-FEB-2010') FROM DUAL; -gives error

  It needs explicit conversion using TO_DATE();

  My question is why what is happening?
  Is it because we have two functions ROUND (NUMBER) and ROUND (DATE)?

  No, it's because there is no ROUND function (VARCHAR2).
  The use of strings which are expected of the DATEs is simply asking for trouble. Sometimes, you get what you're asking.

• Need help for the conversion of the Date

  Hi all

  Your expert input is much appreciated.

  Have a problem where it is my master table structure, whenever there is an update/delete/insert on the main table
  There's a trigger that insert an entry in the Audit table.
  
  SQL > cpp_Master Desc;
  Number of Ent_id
  Date of Ent_date
  
  SQL > Desc Cpp_Master_Audit
  Number of Ent_id
  Date of Ent_date,
  Insert_type varchar2 (1)
  
  The problem is that when we insert the Sub record in the table, the ent_date column appears in this way.
  
  SQL > INSERT INTO CED.cpp_Master (ENT_ID, Ent_date)
  VALUES (6030902, TO_DATE (1 JANUARY 01 00:00:00 ', ' HH24: PUT DD/MM/YYYY "));

  SQL > SELECT * FROM CED.cpp_Master;

  6030902 01/01/0001

  SQL > SELECT * FROM CDS. Cpp_Master_Audit;

  6030902 01/01/0001

  But when I update the date is coming up as below

  SQL > update ced.cpp_Master set Ent_date = to_date (' 1 March 01', ' dd-mon-YYYY "") where ent_id = '6030902';
  SQL > commit;

  Tried under updates so

  (

  Update ced.cpp_Master set Ent_date = ' March 1 01' where ent_id = '6030902';

  Update ced.cpp_Master set Ent_date = to_char (' 1 March 01', ' dd-mon-YYYY "") where ent_id = '6030902';

  )

  Whenever the output below always. (Insert has no problem, just update a problem)

  I wonder why when there is an insertion of the date value is "01/01/01" in (Cpp_Master_Audit), but when I update the date value is "01/01/2001" ".

  I need the value to insert as "01/01/01", as all that was updated in Master table (Cpp_Master)

  SQL > SELECT * FROM CED.cpp_Master;

  6030902 01/01/2001

  
  
  My request to trigger:
  
  CREATE OR REPLACE TRIGGER CDS. CPP_AUDT
  AFTER INSERT OR UPDATE OR DELETE
  ON CED.cpp_Master REFERENCING OLD AS OLD AGAIN AS NEW
  FOR EACH LINE
  DECLARE
  l_action_code VARCHAR2 (1);
  BEGIN

  IF THE INSERTION
  THEN
  l_action_code: = 'I ';
  ELSIF UPDATE
  THEN

  END IF;
  END;

  You wrote that ent_date is of type DATE

  SQL > cpp_Master Desc;

  Number of Ent_id

  Date of Ent_date

  so DO NOT fill with a chain, but with a date, and you have correct data in it.

  This:

  Update ced.cpp_Master set Ent_date = 1 March 01 ' where ent_id = '6030902';

  is simply wrong that fill you your column DATE with a string and your NUMBER column with a string filter too.
  

  
  

  Use

  Update ced.cpp_Master

  Set Ent_date = TO_DATE('01-MAR-0001','DD-MON-YYYY') where ent_id = 6030902;

  and you will have no problems (as long as the NLS_DATE_LANGUAGE parameter is set correctly to support abbreviations English months)

• Download data - problems with the conversion of the date

  Hello
  
  I have a picture that I downloaded from a database of oracle using SAS. It has a column with dates in the following format: 10/31/2012 11:00
  
  When I download the data (via workshop SQL-> utilities-> data workshop-> load data) by categorizing my dates as varchar2, everything works fine... but fails when I choose my type in the Date column.
  
  Please advice how to fix this
  
  Thank you

  K I import my data with other tools. Looking at the workshop of data utility, no doubt you would put MM/DD/YYYY HH: mi: SS AM in the 'Format' field for this column.

• OpenScript / database: String obtained from the data bank cannot be used for parameters

  Hello
  
  I add a jar to java code OpenScript file. Since the need to enter the settings of the front console run the jar file, I think that it can read the settings from the database and then run it as "java-jar filename.jar para1, para2 para3", 2 3 para1 is synonymous with three parameters obtained from the database "
  
  I get the value of the database as follows:
  String para1 = "{{db.caseName.para1}}";
  String para2 = "{{db.caseName.para2}}";
  String para3 = "{{db.caseName.para3}}";
  
  However, it does not work and it looks that this string has the database cannot used as settings in 'java-jar filename.jar para1, para2 para3.
  I'm trying to assign the value directly as: String para1 = 'PARA1 '; String para2 = "PARA2; String = 'PARA3; then can run 'java-jar filename.jar para1, para2 para3' and this can work.
  
  So, how can I use parameters got in 'java-jar filename.jar para1, para2 para3' database successfully?
  Thank you very much ^ _ ^!
  
  Kind regards
  Angyoung

  Hello

  You can use eval() for this. That is to say. Use the following method

  String para1 = eval ("{{db.caseName.para1}}");
  String para2 = eval ("{{db.caseName.para2}}");
  String para3 = eval ("{{db.caseName.para3}}");

  then run "java-jar filename.jar para1, para2 para3.

  No it's not.

  You're not extract all lines, you use Toad or some other GUI to confuse you. Enter the results data grid and type CTRL + end to fetch the last row. Or use sqlplus. The selection will fail too.

  Your requirement is to get the "parentcustomdetails" inside the node 'parentruledetails '.

  The following code will do that.

  NodeList children = doc.getDocumentElement().getChildNodes();
  for (int i = 0; i < children.getLength(); i++) {
       Node parentRule = children.item(i);
       if (parentRule.getNodeName().equals("Parentrule")) {
            NodeList nlParentRule = parentRule.getChildNodes();
  
            for (int j = 0; j < nlParentRule.getLength(); j++) {
                 Node parentRuleDetails = nlParentRule.item(j);
                 if (parentRuleDetails.getNodeName().equals(
                           "parentruledetails")) {

                                .getChildNodes();
  
                      for (int k = 0; k < nlParentRuleDetails.getLength(); k++) {
                           Node parentCustomDetails = nlParentRuleDetails
                                     .item(k);
                           if (parentCustomDetails.getNodeName().equals(
                                     "parentcustomdetails")) {

• Reliability of the data in the conversion to &amp; from a Variant...

  It is possible to convert any data type to a variant, and then turn it back on.  In doing so, are there data types who will lose information during the conversion process?  If so, why?

  Yes, you can convert any type to a variable ranging and back. There is a VI called "Variant data" which will have a type as input. He continued to convert the variant the correct data. The side variant must know what type of data to expect. He can pull of the Variant. However, you can use a cluster of generic data that consists of a username and a Variant. Then you can have different types of data which can handle the side reception. It is a two-step process. One of conversion the variant of general type (data type and Variant cluster). The second would be a case statement uses the type then covert the internal variant to the specified type. This approach is used for generic messaging systems. The upper levels of the code will know what to do with the data. The lower levels are just generic data passing around.

  I'm not aware of any information that get lost during the conversion of the data to and from a variant. Of course, I not had no problem using them.

• the date conversion problem

  Hi friends,

  I have a problem with the conversion of the date in my PB.

  SELECT eff_dt, TO_CHAR (TO_DATE (eff_dt, 'Dd-mon-yy'), 'dd-mm-yyyy') DATE from une_table;

  It gives me o/p as -.

  DATE OF EFF_DT

  01.01.1950 00:00:00 01/01/2050

  as you can see here the year is wrong, while I convert the date that I use the substr() also to cut the year of first line, but it gives me the 50 i.e. onle last (YY)

  So, if someone can help me with this prob.

  If eff_dt is a column DATE, then stop calling to_date on it.

  If this is not the case, consider making it into a DATE column. If you are unable to do this, use the format mask appropriate when you call to_date

• How to read the date of the day of the day of the year?

  I want to put 30 days for the test of endurance for the application of the components. the user will have the current value of 30 days with specify them the end of the day.

  I saw that the "seconds to Date/Time.vi" sure I checked the day of the year. If I can use this day of the year, I can add + 30 read 30 date.

  Barros,

  What I gave was the answer you were looking for originally because I believe.  You will not just be able to read the date in a coherent way and then add 30.  You can either use the function Get time in seconds or a few varaint it and then add the offset you want (you could use the get a Date/time string and enter the date directly, but this digital conversion which will be useful in the monitoring of the time elapsed will be much more difficult than what I provided only).  If you want to stop the test, simply to keep track of the amount of time the test is in pause and extension at the time where that amount.
