How to compare two date Objects
Hi,
I have two Calendar Objects, one is coming from client and one is my server time, I need to evaluate that incoming time with server time so that if it is sent before an hour back then i should not do anything on that request Object. I have converted the incoming String into Calendar Object and how can i evaluate these two Calendar Objects including their hours and minutes.
Thanks in advance

Also make sure that the two date objects are in the same date format..
public static String DateToDateString(java.util.Date d, String dateFormat)
throws ParseException {
SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
sdf.setLenient(false); // this is required else it will convert
String dateString = sdf.format(d);

Hi,
I have two colums(start date &end date) of data type date in my page and both are optional ones.
I need to have a validation on those date columns,
End date should not be greater than Start Date.
This validation should be triggered once i click on Apply button.
Pseudo Code:
If (endate>startdate)
raise form_trigger_failure;
Can anyone suggest how/where to implement the code, if possible please provide the sample code.
Thanks,
Maheshsorry, I was thinking java and not oaf
there is similar thing thats done in tutorials exercise create page part2
this is the code snippet from jdev guide...but you may want to go through the chapter before you put this code in your EO file.
Step 10.2 Add a validateEndDate() method Add the following new method to your EmployeeEOImpl class. /*
* Verifies that the employee's End Date is valid.
* Business Rules:
* This is an optional value which can be updated at any time.
* Cannot be earlier than sysdate.
protected void validateEndDate(Date value)
// If a value has been set, validate it.
if (value != null)
OADBTransaction transaction = getOADBTransaction();
// Note that we want to truncate these values to allow for the possibility
// that we're trying to set them to be the same day. Calling // dateValue( ) does not include time. Were we to want the time element,
// we would call timestampValue(). Finally, you cannot compare
// oracle.jbo.domain.Date objects directly. Instead, convert the value to
// a long as shown.
long sysdate = transaction.getCurrentDBDate().dateValue().getTime();
long endDate = value.dateValue().getTime();
if (endDate < sysdate)
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // EO name
getPrimaryKey(), // EO PK
"EndDate", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_END_DATE_PAST"); // Message name
} // end validateEndDate() -
How to compare two database objects?
Hi,
I need to compare two objects with embedded objects/collections in it to tell exact difference between the two.
e.g.,
create type t1 as object (name varchar2(10), age number);
create type t2 as table of t1;
create type t3 as object (user t1, family t2);
... and so on.. this type hirarechy is big in my case..
I want a procedure/function which can tell me what and where is the difference.
PROCEDURE (obj1 T1 , obj2 T1) IS
BEGIN
END;
e.g., t1.name = 'John' and t2.name = 'Mich' then it should return t1.name etc..
Is it possible?

How to compare two Objects !!!!
Hi All,
I know that this question has been asked 100 times till now. But trust me I have checked all of them but couldn`t find answer. Here is my question:
I have an objecs. In that object I am setting (Id,Name,DOJ). Now I want to check whether the object I am trying to save in database already exists or not. If exists then I need to check whether all the setters are same for the two objects. Now can anyone tell me ,how to compare two objects directly without comparing the setters individually.
Thanks in advance.pavan13 wrote:
That is pretty good idea. However I have a query. Does that code actually compare all the setters in a two beans. I don`t want to check each setter seperately.Well, it's pretty meaningless to talk about "comparing setters", setters are methods, they don't have values to compare. Because equals is inside the class, you can simply compare the fields that get set by the setters. "Properties" is probably a better name.
In principal you could write something that tried to find all relevant fields and compare them, using reflection or bean info stuff. The resulting code would be about 50 times longer and take about 50 times longer to run. It's hardly asking a lot to put three comparisons between && operators.
Remember, though, not to compare string fields with ==, you should call .equals on the string fields.
p.s. don't let the bean terminology confuse you. Beans are just ordinary objects which follow a few rules. Personally I wish the term had never been coined.

??how to compare two resultsets??
hi all!
i need to find out whether two resultsets contain the same data.
the only way i know how to do it in java is to put them into a while loop and fetch the contents first and then compare the contents.
but is there an easier way to compare resultsets?
does anyone know how to compare two resultsets without extracting the data?
the code example here executes two identical queries on an oracle database, compare and print the resultsets.
public ResultSet getResultset(String query)
ResultSet rs=null;
try { rs=Stmt.executeQuery(query); }
catch(Exception e) { e.printStackTrace(); }
return rs;
public static void main(String[] args) {
ResultSet r1=null;
ResultSet r2=null;
try {
database db = new ddatabase();
r1=db.getResultset("Select 'name' from person");
r2=db.getResultset("Select 'name' from person");
if (r1 == r2) {
System.out.println("ok");
System.out.print(r1);
System.out.println();
System.out.print(r2);
else {
System.out.println("not ok");
System.out.print(r1);
System.out.println();
System.out.print(r2);
jdbc.cleanup();
catch(Exception e) {e.printStackTrace();}
and here is the output:
F:\java rs_compare
not ok
oracle.jdbc.driver.OracleResultSetImpl@4413ee
oracle.jdbc.driver.OracleResultSetImpl@786e64
as you can see the resultsets are different though the data they contain have to be the same.
so the 'if(resultset#1 == resultset#2)' does not work.
thanks for any help
best regards
5ithl0rdDon't cross-post.
I'll bet ResultSet implementations don't override equals() to provide "deep equals" behavior, in which case it'll be no different than using "==".
It's a bad idea to compare two ResultSets this way. You'll have to load both into objects or data structures and compare those in a "deep" way.
Besides, the ONLY way two ResultSets could be different, given the same query, would be if there were multiple clients that could write to the table between queries and change the underlying data. If your two queries are sufficiently isolated, I'd say that the same query will return the same ResultSet.

How to compare table data and table field
Hi buddy,
I have some question about how to compare table data and table field.
1. I know there is one method: CL_ABAP_UNIT_ASSERT=>ASSERT_TABLE_CONTAINS , it use in unit test to compare the table data(A and B) , you can loop table A into structure A1, then use this mehtod it can compare whether table B contain structure A1. but when I try to use this in main program it will dump.
CL_ABAP_UNIT_ASSERT=>ASSERT_TABLE_CONTAINS(
LINE = A1
TABLE = B ).
Is there any method or FM can be used to compare the table data ?
2. I also want to compare two table field , try to find out the different. How to realize this.
Thank you for your sincerely answer.Hi Zongjie,
What`s the difference, if you using loop A into wa_A, read table B into wa_B with all field, then compare with wa_A and wa_B.
The question 2, seems no standard FM available here.
Loop A into wa_A.
Loop B into wa_B.
if wa_A-field1 eq wa_B-field1.
endif.
if wa_A-field2 eq wa_B-field2.
endif.
endloop.
endloop.

Comparing two dates and adding days to date
Hi,
I want to compare two dates(like 2006/10/21 and 2006/11/2),how can i compare these two dates,like which is greater.And if to the second date,i want to add some number of days like 10 days,how can i add so that the date becomes 2006/11/12).
Please reply soon.ThanksNo,all other queries are different,as they have the
date in this format
'2006-03-06 " but i have the date in this format
"2006-03-06 10:26:46.0",
i.e the time is also assciated with it.
If I have only the date(in string format or date
date format 2000/12/1),then I can easily do it,but
I have the time also.If I have the date only,then I
can split the date into three strings,and after
converting into integer I can pass it to the
constructor,but what about the time?SimpleDateFormat can parse "2006-03-06 10:26:46.0" date too:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.SS");
Date date = dateFormat.parse("2006-03-06 10:26:46.0");
System.out.println("date = " +date); -
