Need help in Data Dictionary record upload
Hi All,
In my table I have 2 fields. Say FIELDA and FIELDB.
FIELDA is INT type and FIELDB is of CHAR type.
I have created a table maintenance generator and DB Utility is also done.
Now I want to upload the following record into the table.
FIELDA should be loaded with value '1'
FIELDB should be loaded with value '!' (Just Exclamatory sign)
When doing the same, FIELDA only gets populated into DB and not in FIELDB '!'. How can I over come this.
Points Assured,
Regards,
Viji
Hi there.
The best way to populate a table is with a program. However, you can do that in SM30. This may look stupid but to input the exclamation mark in SM30 you have to do it twice, i.e, put the mark and press enter. The mark will dissapear. After that, put it again and press enter again and it will be keeped.
This happens because it's a speccial character.
Best regards.
Valter Oliveira.

Sreekanth Note: Please vote/mark the post as answered if it answers your question/helps to solve your problem.*****Hello,
In SSRS, Report items within a report can be
kept together on a single page implicitly or explicitly by setting the keep with group or keep together properties.
In your case, you can try to specify the "KeepTogether" property to True on the Table properties windows.
If there are other report items under or above the Table and you want keep all items on the single page, you can try to add a Rectangle and put all items into the Rectangle.

I am printing a calendar and certain events will be helds on certain dates.
One can edit the event if it has not passed the date. Events in the past can be viewed but not edited.
When I query the database the date must be formatted dd-MMM-yy
I am able to get today's date by doing this:
java.util.Date today = new java.util.Date();
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
String today_str = sdf.format(today);
My code for printing the calendar: I left out some of the table formatting in the JSP page.
GregorianCalendar d = new GregorianCalendar();
int today = d.get(Calendar.DAY_OF_MONTH);
int month = d.get(Calendar.MONTH);
d.set(Calendar.DAY_OF_MONTH,1);
int weekday = d.get(Calendar.DAY_OF_WEEK);
for(int i = Calendar.SUNDAY; i < weekday; i++)
out.print("<td> </td>");
do {
int day = d.get(Calendar.DAY_OF_MONTH);
out.print("<td>" + day + "</td>");
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
if(weekday == Calendar.SATURDAY)
out.println("</tr><tr valign=top>");
d.add(Calendar.DAY_OF_MONTH,1);
weekday = d.get(Calendar.DAY_OF_WEEK);
} while(d.get(Calendar.MONTH) == month);
if(weekday != Calendar.SUNDAY)
System.out.println();
The part I need help on is this:
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
I'm looping through each day of the month to print the days. I have the month, day, year as integers. How can I create a date object out of that and compare it to today's date to test if it's before or after today???
All the function in the Date class that I think would do this have been deprecated.Need Help with Dates
Here is some information about dates:
There are many edible palm fruits, and one of the most widespread and favored of these is the data (Phoenix dactylifera). Dates were cultivated in ancient land from Mesopotamia to prehistoric Egypt, possibly as early as 6000 B.C. Then--as now--dates were a staple for the natives of those dry regions. Much later, Arabs spread dates around northern Africa, and dates were introduced into California by the Spaniards in 1765, around Mission San Ignacio.
The date prefers dry, hot climates, because date fruits are injured at temperatures of 20 degrees F, and the damp climate of the California coast was not favorable for fruit production. In the mid-1800s, the date industry developed in California's hot interior valleys and in Arizona. Now the date industry in the United States is localized mostly in the Coachella Valley, where the sandy soils permit the plants to be deeply irrigated. Today the new varieties, mostly introduced in this century, produce about 40 million pounds of dates per annum, or over 60% of the dates consumed in this country. The rest are imported mainly from Persia. According to one survey, about one million people are engaged entirely in date palm cultivation worldwide.
Hope that helps. -
Need help in date Validation Urgent
Hi ,
We need help in Date Validation.
we have 2 Date fields on the form Start Date, End Date
The requirement is: End Date (May not be greater than 30 years from the start date).
I have written following script on End Date Exit event. But the problem is its calculating 30 years from the Current Date not from the Start Date
var tDate = util.scand("mm/dd/yyyy", new Date());
var M = tDate.getMonth();
var D = tDate.getDate();
var Y = tDate.getFullYear();
var SRes = util.printd("yyyy-mm-dd", new Date((Y+30), M,D) );
//app.alert(SRes)if (SRes <= this.rawValue){
app.alert("May not be greater than 30 years from the start date")

this);}
can someone please help me

You'll need to get javascript date from LCD field, and calculate & compare with the future date in javascript date.
try following script;

Need Help With File Matching Records
I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do. -
Need help with date range searches for Table Sources in SES
Hi all,
I need help, please. I am trying to satisfy a Level 1 client requirement for the ability to search for records in crawled table sources by a date and/or date range. I have performed the following steps, and did not get accurate results from Advanced searching for date. Please help me understand what I am doing wrong, and/or if there is a way to define a date search attribute without creating a LOV for a date column. (My tables have 500,00 rows.)
I am using SES 10.1.8.3 on Windows 32.
My Oracle 10g Spatial Table is called REPORTS and this table has the following columns:
TRACKNUM Varchar2
TITLE Varchar2
SUMMARY CLOB
SYMBOLCODE Varchar2
Timestamp Date
OBSDATE Date
GEOM SDO_GEOMETRY
I set up the REPORTS table source in SES, using TRACKNUM as the Primary Key (unique and not null), and SUMMARY as the CONTENT Column. In the Table Column Mappings I defined TITLE as String and TITLE.
Under Global Settings > Search Attributes I defined a new Search Attribute (type Date) called DATE OCCURRED (DD-MON-YY).
Went back to REPORTS source previously defined and added a new Table Column Mapping - mapping OBSDATE to the newly defined DATE OCCURRED (DD-MON-YY) search attribute.
I then modified the Schedule for the REPORTS source Crawler Policy to “Process All Documents”.
Schedule crawls and indexes entire REPORTS table.
In SES Advanced Search page, I enter my search keyword, select Specific Source Group as REPORTS, select All Match, and used the pick list to select the DATE OCCURRED (DD-MON-YY) Attribute Name, operator of Greater than equal, and entered the Value 01-JAN-07. Then the second attribute name of DATE_OCCURRED (DD-MON-YY), less than equals, 10-JAN-07.
Search results gave me 38,000 documents, and the first 25 I looked at had dates NOT within the 01-JAN-07 / 10-JAN-07 range. (e.g. OBSDATE= 10-MAR-07, 22-SEP-07, 02-FEB-08, etc.)
And, none of the results I opened had ANY dates within the SUMMARY CLOB…in case that’s what was being found in the search.
Can someone help me figure out how to allow my client to search for specific dated records in a db table using a single column for the date? This is a major requirement and they are anxiously awaiting my solution.
Thanks very much, in advance….raford,
Thanks very much for your reply. However, from what I've read in the SES Admin Document is that (I think) the date format DD/MM/YYYY pertains only to searches on "file system" sources (e.g. Word, Excel, Powerpoint, PDF, etc.). We have 3 file system sources among our 25 total sources. The remaining 22 sources are all TABLE or DATABASE sources. The DBA here has done a great job getting the data standardized using the typical/default Oracle DATE type format in our TABLE sources (DD-MON-YY). Our tables have anywhere from 1500 rows to 2 million rows.
I tested your theory that the dates we are entering are being changed to Strings behind the scenes and on the Advanced Page, searched for results using OBSDATE equals 01/02/2007 in an attempt to find data that I know for certain to be in the mapped OBSDATE table column as 01-FEB-07. My result set contained data that had an OBSDATE of 03-MAR-07 and none containing 01-FEB-07.
Here is the big issue...in order for my client to fulfill his primary mission, one of the top 5 requirements is that he/she be able to find specific table rows that are contain a specific date or range of dates.
thanks very much! -
Need Help with data type conversion
Hello People,
I am new to java, i need some help with data type conversion:
I have variable(string) storing IP Address
IPAddr="10.10.103.10"
I have to call a library function which passes IP Address and does something and returns me a value.
The problem I have is that external function call in this library excepts IP Address in form of a byte array.
Here is the syntax for the function I am calling through my program
int createDevice (byte[] ipAddress).
now my problem is I don't know how to convert the string IPAddr variable into a byte[] ipAddress to pass it through method.Class InetAddress has a method
byte[] getAddress() You can create an instance using the static method getByName() providing the IP address string as argument. -

I need help restoring data from my time machine.
1) On the time machine, where do I find the TRASH file that is located on the dock in my desktop? I'd like to restore that to a prior date but can't find it.
2) I DID A VERY BAD THING & need help to get back to where I was before. I wanted to delete files that were taking up lots of space. My OTHER section was using 160G. I downloaded OmniDiskSweep and found that 120G was being used by my virtual machine (I run Quicken in Windows, through VMware). I started to delete files that were called Snapshots assuming these were the snapshots that the program regularly takes of my files. Apparently they were not. I also deleted the program Windows XP Professional because that was never used. When I try to open VM or quicken program, it says it is missing a particular snapshot, i.e. Snapshot 11104. I deleted about 20 of these. I left all the other files that said Windows XP Home Edition. But now it shows that I only have the Professional Edition, even though that's what I deleted. I'm trying to restore from Time Machine and it looks like the information is not there - I've tried various different backups and nothing seems to have the information I need. The earliest back up I have is from 5/7 when I started time machine on a new external 1TB HD. Would that have the information I need since it's the very first back up? Please Help.I am assuming it's real data because it's taking up storage on my HD. It falls in the category "other" and the total of this section is 160G. Here is a snapshot of the virtual machine.
I also took a shot of the VM snapshots & it tells how much space is being taken up by the snapshots.
I've now changed the number of snapshots taken down to 12 (didn't know I had this option) & I can delete alot of the 21 snapshots that have already been saved. I have no idea how much of the HD was set aside for the VM because someone else installed it for me 5 years ago. I've had enough problems with it over the years that I've wanted to switch to Quicken for Mac or find another financial program to use. I've upgraded the VM 2x over the years, but didn't want to spend $100 for Version 5. I understand the concept of a VM but that's about all.
I did do the disk cleanup in Windows on the C drive. I deleted 700 MB of temporary files and then compressed 4G of data down to 2G. While the cleanup was progressing it said that the C drive was 30.99G and 78% of it was free. That just doesn't make sense to me. It recommended a defrag, so I did that also.
I'm pretty sure it's real data because I recently had to switch from a 320G external HD for TM, to a 1T HD. One TM backup was over 300G which I found to be excessive because I basically use my computer for mail, some word processing, and my financial data.
Thanks again for all your help. I really appreciate it. -

Hi,
I need to print date in the following format:
Jan 21, 2007
11:23 AM 21/01/2007
21-01-2007 18:23
Now as per condition of assignment the year, month, day and hour, min, sec all are entered as separate integer values.
my code:
import java.util.*;
import java.text.*;
public class stringToDate
// Integer value of date and time variables
int day=21;
int month = 1;
int year=07;
int hour=18;
int min=23;
int sec=14;
// Converting integer value into date
public void convertIntoDate()
String strTmp= day+"/"+month+"/"+year+" "+hour+":"+min+":"+sec;
System.out.println("String: " + strTmp);
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
try
Date outDate = dateFormat.parse(strTmp);
System.out.println("Converted: " + dateFormat.format(outDate));
catch(Exception e){ System.out.println("Exception: " + e);}
public static void main(String args[]) {
stringToDate dF = new stringToDate();
dF.convertIntoDate();
}Now as per my code i am able to print in the following format:
String: 21/1/7 18:23:14
Converted: 21/01/0007 18:23:14
But if i try to print in other formats it gives me following error message:
Exception: java.text.ParseException: Unparseable date: "21/1/07"
Please help me....vinee wrote:
