Coverting from a string to an integer
Hi:
Is it possible to covert a string to an integer?
For example I want to convert the following string values to integers so that I can develop a method to use java.util.Date to test for overlapping appointments.
Ex:
markCalendar.addApp(new Appointment("June 1","3pm","4pm", "dentist"));
I want to convert the startTime and the endTime to integers. And compare the startTime and endTime to a vector of appointments.
Should this approch work?
Thanks.

First I would like to suggest, DONT use the class names that have already being defined in JAVA, Here you have used, CALENDAR class, this approach should be avoided, If this class is in the same project where you also want to use the JAVA CALENDAR class, then you mite not be able to do so.
As for the conversion, A simple way is that:
You already know that the time cannot go more than 2 digits (Specifically not more than 24 hours in case of hours and 60 in case of minutes) and the (am) (pm) takes 2 more places, so what you can do is validate if the string size is 4 or 3, if 4 then take the first 2 substrings i.e. somestring.substring(0,2) and then use the Ineteger.parseInt(some string) method.
similarly if the String size is 3 then take the first substring
e.g. somestring.substring(0,1)
This is how you can convert the string to the Integer and compare it, You can store it as an Integer Object and store it in the Vector If you want to.
Hope this helps

Converting a String to an integer?
i need to convert a string to an integer..i searched through the site but i didn't find anything...
Is this conversion possible?You didn't look very hard - it's right in the javadocs:
String s = "44";
int x = Integer.parseInt(s);I'll leave the exception handling for you. -
Conversion from string "20041023 " to type 'Date' is not valid.
Hi ,
I have a table with one of the column(EmpHiredate) datatype is char(10). It has value like "20141023". I need to display this value as date format(dd/mm/yyyy) in report.
Following methods i tried in textbox expression but no luck.
=Format(Fields!EmpHireDate.Value,"dd/MM/yyyy")
=Cdate(Fields!EmpHireDate.Value)
Error:
[rsRuntimeErrorInExpression] The Value expression for the textrun ‘EmpHireDate.Paragraphs[0].TextRuns[0]’ contains an error: Conversion from string "20041023 " to type 'Date' is not valid.
Is it possible to convert string to date using SSRS textbox expression ? Can anyone help me with the solution.
Thanks,
KittuHi Jmcmullen,
Found one more issue on the same. I have one value like "00000000" for the column(EmpHiredate)
, when i use above expression values(ex:"20141023")
are displaying in dd/MM/yyyy format in report except value like "00000000" and giving following error:
[rsRuntimeErrorInExpression] The Value expression for the textrun ‘EmpHireDate.Paragraphs[0].TextRuns[0]’ contains an error: Conversion from string "0000/00/00" to type 'Date' is not valid.
Even i tried to pass its original value("00000000") as below but no luck.
=IIF(Fields!EmpHireDate.Value = "00000000","00000000",Format(CDATE(MID(Fields!EmpHireDate.Value,1,4) + "/" + MID(Fields!EmpHireDate.Value,5,2) + "/" + MID(Fields!EmpHireDate.Value,7,2)),"dd/MM/yyyy"))
Also tried this:
=IIF(Fields!EmpHireDate.Value = "00000000","2000/10/21",Format(CDATE(MID(Fields!EmpHireDate.Value,1,4) + "/" + MID(Fields!EmpHireDate.Value,5,2) + "/" + MID(Fields!EmpHireDate.Value,7,2)),"dd/MM/yyyy"))
Please Suggest.
Thanks ,

Conversion of string into XML object
Hi
I am having some problems with conversion of string (containing XML data) into Flex XML object and binding it later to UI elements to output/maintain this data.
Binding of XML structure to UI elements works perfectly fine if I will do following:
1) Hardcode XML object within Flex file
2) Read xml file from repository (xml file inside the Flex project)
3) Use HTTP request to retrieve XML data
Unfortunately none of the above scenarios suits my solution.
I am developing a prototype application for processing Flex forms inside SAP system. I have decided to make data bindings using XML structure stored in Data Base. When rendering form inside web browser based application I am retrieving corresponding XML schema (empty for new forms and populated for saved forms) and pass it to Flex form as a string type import parameter. Data is being passed correctly (I can display it on TextArea control for instance) but after conversion to XML and binding to DataGrid I am not getting any results.
I am converting string (containing XML) to XML object in following way:
Private var xml_obj:XML = new XML(string_xml );
I am catching any potential errors but conversion is going well. After conversion I am not getting any results after binding it to DataGrid control and I am not able to access any of the nodes using AS code either. At the same time variable xml_obj is not empty (not null).
Any help would be much appreciated.
Regards
MichaelDavid
First of all sorry for not stating it clearly but I am using Flex 3 for this development (at the moment it is the only choice when embedding Flex objects inside SAP applications).
You must have missed the bit where I am describing how this XML data finds its way inside Flex. I am passing it to Flex as String type parameter during rendering (directly from DB where it is stored).
Now, following code works perfect (XML is embedded inside Flex project):
<mx:XML id="form_data" source="../assets/example_xml_data.xml"/>
<mx:Script>
<![CDATA[
import mx.collections.XMLListCollection;
import mx.controls.Alert;
[Bindable]
public var XML_list:XMLListCollection;
private function setParameters():void
XML_list = new XMLListCollection(form_data.*);
]]>
</mx:Script>
<mx:DataGrid id="myDataGrid" dataProvider="{XML_list}">
<mx:columns>
<mx:DataGridColumn dataField="COMMON" headerText="Popular name"/>
<mx:DataGridColumn dataField="BOTANICAL" headerText="Botanical name"/>
<mx:DataGridColumn dataField="ZONE" headerText="Zone"/>
<mx:DataGridColumn dataField="LIGHT" headerText="Light"/>
<mx:DataGridColumn dataField="PRICE" headerText="Price"/>
<mx:DataGridColumn dataField="AVAILABILITY" headerText="Availability"/>
</mx:columns>
</mx:DataGrid>
But following code does not work (XML passed to Flex form as String input parameter):
import sap.FlashIsland;
import mx.controls.Alert;
import mx.collections.XMLListCollection;
[Bindable]
public var xml_data:String;
private var form_data:XML;
[Bindable]
private var XML_list:XMLListCollection;
private function initApp():void
FlashIsland.register(this);
private function setParameters():void
try
form_data=new XML(xml_data);
catch (error:Error)
Alert.show(error.toString());
XML_list = new XMLListCollection(form_data.*);
XML string does find its way inside Flex form. I can display content of variable xml_data in TextArea and all looks fine. Conversion to XML (variable form_data) goes well (no error)
Please helpJ

"Conversion to String failed" When attempting to call rs.getString()
Hello All,
I'm getting a "Conversion to String failed" exception being thrown from oracle jdbc when I attempting to call the rs.getString(1) method on a column type of DATE.
During investigations we've found the following:
1. The query is fine, and is performing a "select * from table".
2. I see this problem when using 9i database (v 9.2.0.7) with 9i jdbc drivers (v9.2.0.7).
3. Strangely enough, if I use 10g jdbc drivers with the 9i database this problem goes away, and naturally I don't see this problem at all using a 10g driver working against a 10g database.
4. Grabbing the DATE value using the getDate() instead of getString() API works just fine in 9i.
5. The 9i rs.getString() API call will work with some date values in the database and not with others.
6. The data placed into the DATE column in question could have been placed there using different driver type from the 9i.
So, the 9i getString() API seems to be a problem.
At this point, based upon points 5 and 6 above, I'm thinking there is a bug in the oracle 9i jdbc drivers that is unable to convert DATE type data using the getString() API if the data was initially placed into the database using a different driver type. But, this would mean that the format of the data in the database would be different depending upon the means of getting the data there in the first place (which doesn't make much sense).
Here is the pertinent Stack Trace:
java.sql.SQLException: Conversion to String failed
at oracle.sql.Datum.stringValue(Datum.java:173)
at oracle.jdbc.driver.ScrollableResultSet.getString(ScrollableResultSet.java:684)
at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:1549)
at com.revenuesolutionsinc.dali.sql.DALResultSet.getString(DALResultSet.java:325)
Any help on this matter would be greatly appreciated.
Thanks,
Doug NewcombDoug,
Pardon me for stating the obvious, but is there a
reason why you cannot use method "getDate()" instead
of method "getString()"?
For your information, you can report bugs via the
MetaLink
Web site.
Good Luck,
Avi.Thanks for the reply Avi,
The main reason is that we've got mountains of code that would need to be refactored. Also, the getString() method worked fine for over a year.
So we are looking towards finding out why this is happening before making the decision to refactor.
I will be placing a TAR with Oracle on Monday, but I thought I'd try to find out if anyone else has run into a similar problem. -
Regional settings impact JavaScript Number conversion to String in applet
Environment:
XP, IE6 and IE7, JDK 1.6.0_13,1.6.0_10,1.6.0_7, Apache
Hi,
We recently converted our application from the MS JVM to Sun JVM 1.6 and have since had numerous problems with a user's regional setting impacting the application's behaviour.
The application is using an applet, passing JavaScript Number values to an Applet where the input argument in the Java function is declared as a String.
We have users with various regional settings, most don't impact the application, but we have found problems when the regional settings are set to "French (France)" or "German (Germany)".
With "French (France)" JavaScript Number values >=10000000 get truncated to a Java String value of just the first character.e.g. 10000000 is converted to "1", 200000000 is converted to "2".
With "German (Germany)" a trailing "0" is added to the converted String, and for values >=10000000 we get the String value with an additional 6 "0"s and then 2 additional "0"s as the input Number value is increments by each power of 10.
A simple example follows.
Any help understanding why this is happening and any coding solution would be appreciated.
The default number format for the various regional settings seems to be impacting the implicit conversion to String in LiveConnect.
We can re-code to convert the Number value to a String in the JavaScript before calling the applet, but this involves significant re-coding of the application.
We also have a workaround to verify that navigator.userLanguage returns one of the list of supported languages and exit the application if the language is unsupported.
Thanks
Rob

String equivalent of Integer.parseInt()
Hey..
Integer.parseInt() reads an integer that is being inputted right? what im looking though is some sort of a String equivalent of Integer.parseInt.
ex:
nString = JOptionPane.showInputDialog("Enter number:");
n = Integer.parseInt(nString);
what im looking:
nString = JOptionPane.showInputDialog("Enter text:");
n = ? (nString);
a keyword that reads the text inputted.how do i reset the counter to 0 if the user tries again? because it doesn't reset and it makes a logical error if the user tries again.
while (trya != 0){
if ((trya > 1) || (trya < 0))
break;
else{
z=JOptionPane.showInputDialog("Choose Difficulty:\n[1]BATHROOM SINGER\n[2]MAINSTREAM MUSICIAN\n[3]GRAMMY WINNER");
x=Integer.parseInt(z);
switch(x){
case 1:
JOptionPane.showMessageDialog(null,"DIFFICULTY: BATHROOM SINGER");
String stringInput = JOptionPane.showInputDialog(q1);
if (stringInput.equals(a1)){
JOptionPane.showMessageDialog(null, "Correct!");
i++;
} else {
j++;
JOptionPane.showMessageDialog(null,"Wrong");
String stringInput29 = JOptionPane.showInputDialog(q15);
if (stringInput29.equals(a15)){
JOptionPane.showMessageDialog(null, "Correct!");
i++;
} else {
j++;
JOptionPane.showMessageDialog(null,"Wrong");
JOptionPane.showMessageDialog(null,"Correct answers: "+i+"\nWrong answers: "+j+"\nTHANKS FOR PLAYING");
break;
default:
JOptionPane.showMessageDialog(null,"Press either [1] [2] or [3]", "ERROR",JOptionPane.WARNING_MESSAGE);
break;
stry = JOptionPane.showInputDialog("Do you want to PLAY AGAIN? \n Press [1] for YES \n Press [0] for NO");

Conversion from string "" to type 'Double' is not valid
We're using BPC 7.5 MS and on patch level 111.02
There's two front-end servers and one back-end. we have about 100 users but concurrency is likely in the 50 range.
We've been running extremely well for about 4 years but are now starting to run into problems.
There are about 5-6 applications but none greater than 10 million records. We optimize regularly.
However over the past two months admin processes seem to take a lot longer. Optimization now times out after about 1.25 hours and none used to take greater than 15 minutes.
Today after processing dimensions we checked the application status and we were not able to check if it was available or not. We got a pop up box saying
conversion from string "" to type 'Double' is not valid
I've processed dimensions and applications since and still this error persists.
We're attempting a reboot to see if that helps but I've never seen this before and in combination with the slower admin processing I'm wondering if there's something drastic going to happen.
MichaelHi Michael,
for the poor performances you have to check the guides about performance on bpc if you have scheduled regurarly optimize during day and night (just verify that never factwb reach 50.000 and fac2 500.000 records) maybe you need to change some parameter on the server as MaxThreads.
For the conversion string error on admin console see please this note 1803092 - Set application set status error

XSU error oracle.xml.sql.OracleXMLSQLException: Conversion to String failed
Appication Server: 10g, Database: Oracle 9i and Oracle 10g
I have a table 'sw_icd2' in the database that has one column of XMLType.
The code below, attempts to query this table as 'select * from sw_icd2' and display the result. I was able to execute this query in sqlplus.
But when I run a program using XSU in JDeveloper:
OracleXMLQuery qry = new OracleXMLQuery(conn, "select * from sw_icd2");
XMLDocument domDoc = (XMLDocument)qry.getXMLDOM();
domDoc.print(System.out);
StringWriter s = new StringWriter(10000);
domDoc.print(new PrintWriter(s));
System.out.println(s.toString());
qry.close();
I get the following Error:
"oracle.xml.sql.OracleXMLSQLException: Conversion to String failed"
Any ideas on how I can resolve this issue? Your help would be appreciated.
Thanks!Okay, it looks like the problem has something to do with the TIMESTAMP data type in tables.
oracle.xml.sql.query.OracleXMLQuery can't seem to handle tables with the TIMESTAMP data type.
this code ran fine on my machine :
import oracle.jdbc.driver.*;
import oracle.xml.sql.query.OracleXMLQuery;
import java.lang.*;
import java.sql.*;
public class testXMLSQL {
public static void main(String[] args) {
try {
// Create the connection
System.out.println("before getConnection ");
Connection conn = getConnection("scott","tiger");
System.out.println("after getConnection ");
// Create the query class
OracleXMLQuery qry = new OracleXMLQuery(conn, "SELECT * FROM EMP");
System.out.println("after OracleXMLQuery object created ");
// Get the XML string
String str = qry.getXMLString();
// Print the XML output
System.out.println("The XML output is:\n"+str);
// Always close the query to get rid of any resources..
qry.close();
} catch(SQLException e) {
System.out.println(e.toString());
// Get the connection given the user name and password.!
private static Connection getConnection(String username,
String password)
throws SQLException
// register the JDBC driver..
DriverManager.registerDriver(new
oracle.jdbc.driver.OracleDriver());
// Create the connection using the OCI8 driver
Connection conn =
DriverManager.getConnection(
"jdbc:oracle:thin:@<server_name>:1521:<sid>",
username,password);
return conn;
Then I created another table :
create table emp_test as select * from emp;
added a timestamp to it :
alter table emp_test add (time timestamp(6));
and filled it with timestamp information :
update emp_test set time = timestamp'2005-09-22 09:26:50.124';
ran the same code but changed the SQL to :
"SELECT * FROM EMP_TEST"
and got the error message :
The XML output is:

Splitting a string when an integer is reached
Hi,
I'm trying to figure out how, if possible, to split a string when an integer comes in the strong. What I'm doing is reading from a web page and the output is "1930Stella" as an example. What I want to do is insert those into a table, so it's like this:
String | Integer
Stella 1930I'm not sure how I can go about doing this, please help!YoungWinston wrote:

WinstonNo, it can't ever be anything other than "1930Stella" or "Stella1930", but it will always be integerString in the format that I'm reading from the site.

Just a thought...
Why not make this function return something like this:

"1930Stella" -> parseString -> "1930|Stella"

You're obviously halfway there, but right now if you want to get both the number and the string out of the input, you have to loop over the input twice. Why not just loop over the input once, insert a delimiter between your 'fields', and call split on the resulting string later? Then again, you know the overall requirements for the issue at hand.
Also, is the input string always a number followed by characters (i.e. 1930Stella), or can it be something ridiculous like "1234abc56d7e8"? I only ask because right now your method only handles the first case nicely, on the assumption that your result will always be "number followed by characters".As I said above, the method works for what I need (only integerString/stringInteger format). I was looking at the delimiter idea but couldn't quite fully understand it. I'll give it another go, though! -
Hi,
I have set db_4k_cache_size.
SQL> alter system set db_4k_cache_size=4k scope=spfile;
System altered.
After shutdown and startup, I see the value as follows,
db_4k_cache_size big integer 4194304
What is this? 4194304 = 4k*1024, why set Oracle the value*1024?SQL> alter system set db_4k_cache_size=4k
scope=spfile;
After shutdown and startup, I see the value as
follows,
db_4k_cache_size big integer
4194304First of all, it must be clear what you are configuring with the db_4k_cache_size. This is a special cache you setup to allow your database to manage different sizes of datablocks. Here you are willing to manage a 4K blocksize Tablespace along with your default block sized tablespaces. A db_block_size different from 4K is assumed.
Next, you are declaring an space of 4K ?! Too short for a database buffer cache. What's the use of reserving a 4K block sized cache to store just one single 4K block?
So a more suitable value must be defined. Let's think about 8M, you could store up to 2,048 4K blocks; a much more reasonable value than 1.
