Converting a Date to a suitable String?

I want to use a Date or GregorianCalendar variable for storing a date (year, month and day).
I need a way to get a string in that format: "19000101". I need a Date in this format because of the SQL statement.
Are there any Classes and Methods I can use for that?

It would go something like this:
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
String convertedDate = sdf.format(new Date());

Convert a date in String format to a Date

Hi,
How can I convert a date in String format to a Date object?
I have tried:
import java.text.*;
import java.io.*;
import java.util.Date;
import java.util.Locale;
import java.sql.*;
public class casa {
public static Connection con = null;
public static Statement s = null;
public static String sql = null;
public static String mydate = "01.01.2001";
/** Creates a new instance of casa */
public casa() {
public static void main(String[] args) throws SQLException{
try {
DateFormat shortFormat = DateFormat.getDateInstance(DateFormat.SHORT);
Date date = shortFormat.parse(mydate);
//Open Database
con = getConnection();
s = con.createStatement();
sql = "select date1 from table1 where date1 <= '"+date+"'";
ResultSet rs = s.executeQuery(sql);
while(rs.next()){
String aba = rs.getString("datum");
System.out.println("New Datum = "+aba);
} catch (Exception ex ) {
ex.printStackTrace();
closeConnection(s, con);
//Connection
private static Connection getConnection() {
Connection con = null;
String user ="aouzi";
String passe ="aouzi";
String url = "jdbc:db2:EjbTest";
try {
//Datenbanktreiber laden
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
//Verbindung herstellen
con = DriverManager.getConnection(url,user,passe);
}catch(ClassNotFoundException e){
} catch(SQLException e){}
return con;
//close Connection
private static void closeConnection(Statement s, Connection con) {
try {
s.close();
} catch (SQLException e) {}
try {
con.close();
} catch (SQLException e) {}
I'm getting the following errors:
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0180N
The syntax of the representation of a date/time of day value as character sequence is false. .SQLSTATE=22007

I'm pretty sure it won't understand what date.toString() returns. If you know what format the database understands, you do it like this:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yy"); // e.g. 18-Apr-02
String datestring = sdf.parse(date);
and use that instead of date in your sql string. Some databases understands it if you do
"to_date('18-Apr-02')"
so you could include that in your sql string as well..
You could also try to make it a java.sql.Date and hope your jdbc driver knows how to convert it to a string that the database understands if you don't know the format:
con = getConnection();
PreparedStatement ps = con.prepareStatement("select date1 from table1 where date1 <= ?");
ps.setDate(new java.sql.Date(date.getTime()));
ResultSet rs = s.executeQuery(sql);

How to convert BLOB data into string format.

Hi,
I have problem while converting blob data into string format.
for example,
Select dbms_lob.substr(c.shape.Get_wkb(),4000,1) from geotable c
will get me the first 4000 byte of BLOB .
When i using SQL as i did above,the max length is 4000, but i can get 32K using plsql as below:
declare
my_var CLOB;
BEGIN
for x in (Select X from T)
loop
my_var:=dbms_lob.substr(x.X,32767,1)
end loop
return my_var;
I comfortably convert 32k BLOB field to string.
My problem is how to convert blob to varchar having size more than 32K.
Please help me to resolve this,
Thanx in advance for the support,
Nilesh

Nilesh,
. . . .The result of get_wkb() will not be human readable (all values are encoded into some binary format).
SELECT utl_raw.cast_to_varchar2(tbl.geometry.get_wkt()) from FeatureTable tbl;
-- resulting string:
☺AW(⌂özßHAA
Å\(÷. . . .You may also want to have a look at { dbms_lob | http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i1015792 } "The DBMS_LOB package provides subprograms to operate on BLOBs, CLOBs, NCLOBs, BFILEs, and temporary LOBs."

Convert the date of string to datetime format 'MM/dd/yyyy' when the system date format is 'dd/MM/yyyy'.

I need convert the date of string format 'MM/dd/yyyy' to datetime format 'MM/dd/yyyy' when the system date format is 'dd/MM/yyyy'.Since
I need to search values based on date where my database datetime is 'MM/dd/yyyy' format.

In my opinion you should re-consider the assumption that the date picker returns a string. Maybe it is able to return a
DateTime object directly instead of string. Then you will pass this value as a parameter of SQL query. This should work regardless of computer configuration.
Otherwise, follow the previous string-based approaches.

Converting any date string to GMT standard

Hi All,
I want to convert any date string to GMT standard.
The date string may be like this.
"Sat Sep 15 14:23:40 IST 2001"
I have tried to change my defaultTimeZone .
But I don't know why it's not working.
Is there something to do with Locals?
Can anyone please tell me the way to
accomplish that ?
Thanks in advance.
Sujoy

Java stores all the dates in GMT Format , considering the machines TimeZone Setting ....and also i guess date has methods like toGMTString() and toLocaleString() . To convert the date to GMT i guess u can just say toGMTString() of the date . If u have the stringified version of date
just make a new Date(String) and then calling toGMTString of it .

How to convert DateField date to String ?

Hi,
I'm trying to convert DateField date to String.
How can I do it because Data class does not have String converting
methods...
Thanks
Krzysztof

Hello,
you can get an instance of Calendar and use it with the date as a long integer.
public Calendar cal=Calendar.getInstance();
myDate=dateField.getDate();
cal.setTime(myDate);
myDateString=cal.get(Calendar.DATE)+"."+cal.get(Calendar.MONTH)+"."+cal.get(Calendar.YEAR));
Try it.
Unfortunately I have found that the MIDlet get a day less when I use the same long integer that I got from an application on PC. I don't realy understand why but I' still searching.
I hope it is usefull for you.

SSIS Package : While Extracting Sharepoint Lookup column, getting error 'Cannnot convert between unicode and non-unicode string data types'

Hello,
I am working on one project and there is need to extract Sharepoint list data and import them to SQL Server table. I have few lookup columns in the list.
Steps in my Data Flow :
Sharepoint List Source
Derived Column
its formula : SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1))
Data Conversion
OLE DB Destination
But I am getting the error of not converting between unicode and non-unicode string data types.
I am not sure what I am missing here.
In Data Conversion, what should be the Data Type for the Look up column?
Please suggest here.
Thank you,
Mittal.

You have a data conversion transformation. Now, in the destination are you assigning the results of the derived column transformation or the data conversion transformation. To avoid this error you need use the data conversion output.
You can eliminate the need for the data conversion with the following in the derived column (creating a new column):
(DT_STR,100,1252)(SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1)))
The 100 is the length and 1252 is the code page (I almost always use 1252) for interpreting the string.

Column "A" cannot convert between unicode and non-unicode string data types

I am following the SSIS overview video-
https://secure.cbtnuggets.com/it-training-videos/series/microsoft-sql-server-2008-business-development/6143?autostart=true
I have a flat file that i want to import the contents onto a SQL database.
I created a Dataflow task, source file and oledb destination.
I am getting the folliwung error -
"column "A" cannot convert between unicode and non-unicode string data types"
in the origin file the data type is coming as string[DT_STR] and in the destination object it is coming as "Unicode string [DT_WSTR]"
I used a data conversion object in between, dosent works very well
Please help what to do

I see this often.
Right Click on FlatFileSource --> Show Advanced Editor --> 'Input and Output Properties' tab --> Expand 'Flat File Source Output' --> Expand 'Output Columns' --> Select your field and set the datatype to DT_WSTR.
Let me know if you still have issues.
Thank You,
Jay

Cannot convert between unicode and non-unicode string data types.

I'm trying to copy the data from 21 tables in a SQL 2005 database to a MS Access database using SSIS. Before converting the SQL database from 2000 to 2005 we had this process set up as a DTS package that ran every month for years with no problem. The only way I can get it to work now is to delete all of the tables from the Access DB and have SSIS create new tables each time. But when I try to create an SSIS package using the SSIS Import and Export Wizard to copy the SQL 2005 data to the same tables that SSIS itself created in Access I get the "cannot convert between unicode and non-unicode string data types" error message. The first few columns I hit this problem on were created by SSIS as the Memo datatype in Access and when I changed them to Text in Access they started to work. The column I'm stuck on now is defined as Text in the SQL 2005 DB and in Access, but it still gives me the "cannot convert" error.

I was getting same error while tranfering data from SQL 2005 to Excel , but using following method i was able to tranfer data. Hopefully it may also help you.
1) Using Data Conversion transformation
data types you need to select is DT_WSTR (unicode in terms of SQL: 2005)
2) derived coloumn transformation
expression you need to use is :
(DT_WSTR, 20) (note : 20 can be replace by your character size)
Note:
Above teo method create replica of your esting coloumn (default name will be copy of <coloumn name>).
while mapping data do not map actual coloumn to the destination but select the coloumn that were created by any of above data transformer (replicated coloumn).

How to fix "cannot convert between unicode and non-unicode string data types" :/

Environment: SQL Server 2008 R2
Introduction:Staging_table is a table where data is being stored from source file. Individual and ind_subject_scores are destination tables.
Purpose: To load the data from a source file .csv while SSIS define table fields with 50 varchar, I can still transfer the data to the entity table/ destination and keeping the table definition.
I'm getting validation error "Cannot convert between a unicode and a non-unicode string data types" for all the columns.

Converting a date to a string

Post Author: ralc002
CA Forum: Formula
I have done a quick search of the forums but did not find what I needed so here it goes:
I have a date field (which is really a date time field - sql). I only use the date so the time is always 00:00:00
Now I have a formula which shows "The last stored date is " & ToText()"
Obviously doing that would show the time (00:00:00). Now I realize that I could format it to exclude the time (e.g. ToText(,"dd/MM/yyyy"), but the problem is doing that hard codes the format. If I create a report for international use, the date format I used in the example would not be valid in the US for example, since it is in british format.
Is there a way to convert a datetime field to a string so that only the date (and not the time) is displayed in the proper format for the current locale?
Thanks

How about just
"The last stored date is " & date()
and that way no matter who sees the report, their local settings will determine how the date is displayed.

Converting premitive data types into strings

Hello everybody,
I have a small doubt. Is it possible to convert all data types like int, boolean etc to strings. I know it is possible to convert them individually. But I would like to have it a common method to convert them all. Because I am reading the whole line, so it is taking as strings. I am unable to read their original data types, all are reading as strings.
Can anybody tell me how to solve this problem?
Thank you in advance,
Kashi.

Hi all,
Thanx for your answers. But as I told you before I don't know the exact data type of those. Because I am reading whole file by using DataInputStream's readLine() method. It returns the whole line as String. If there are any integer or boolean etc, it converts them as strings. So I could not read the exact data type of them.
for example:
int a = 10;
boolean b = true;
String str = "The Values are" + a + b;
this code is in one file. If I read this file from another file, the line
String str = "The Values are" + a + b;
reads as a string, but I couldn�t get the 'a' as ineger and 'b' as boolean. it gives they are of strings.
Thanx,
Kashi.

Hi,
did you show the id-value in the user interface as a input-component, and did the input-component include a converter?
If yes, show the id as output-text and remove any existing converter-components.
Best Regards
