Binary value to string

Hi,
I want to convert binary value to string format. How can i do that if possible please give me sample code.?
One more question is i want to do reverse thing also that is convert string value to binary format.?
Waiting for reply

There are methods in Integer, Long etc for transforming to binary.
I think there are probably also methods to go from binary to an int. Check out the JavaDoc

Assigning a hex value to a variable and getting binary value of a variable.

I try to develop java programs and I need to do a conversion unicode to EBCDIC and vice versa.
How can I assign hex values to variables to build UTF-EBCDIC and EBCDIC-UTF table and get hex or binary value of data to compare it to value of in the table?
I did a conversion like this with PL/1 before. I do not know how can I do it with Java. Because I am new to Java.
Thank you in advance.

I will run java code in mainframe and java uses
unicode for data in default and mainframe environment
is EBCDIC. So I have to translate the data from
unicode to ebcdic.I said I think String supports EBCDIC encoding...
String ebcdic = new String(ebcdicBytes, "Cp500");

Need to convert a binary value into decimal

Hi i need to convert a binary value which i would be getting as a string object to a decimal value......need code for the same

Assigning a binary value to an integer

Hi, I am trying to assign a binary value in my program to an integer. In some assembly languages you would do the following:
mov a, 00010101b
for binary and for hex:
mov a, 0E2h
In java, you can assign a hex value with:
int a=0x3F;
What should I do to assign a binary value? Is it possible?
Regards... Martin Schmiedel

The static method parseInt in the java.lang.Integer class can be used to convert a String representing a binary number into its decimal integer value. In addition to the string representing the number, you also pass in an integer representing the radix, which for binary would be 2, hex would be 16, etc. So for example:
int x = Integer.parseInt("00010110", 2);
Is that what you're trying to do? Cheers,

Binary Values unreadable - Database corrupt?

Hi,
I'm experiencing a really weird problem here, I have a table with some varchar columns and two binary columns. What I do now, is to select data from it via Python with the following select statement:
select * from torder where customerid=1624 order by torderid desc
What happens is, that only for this customerid some binary data is missing, they contain an empty string. If I do the select like this:
select * from torder where customerid=1624 order by torderid
It does work, the data is there. With this, it works too:
select * from torder order by torderid desc
So it seems, the combination of "customerid=1624" and "desc" somehow corrupts the results.
What's furthermore interesting is, that when I delete the last inserted row of the result, it works, and if I add a new one, it's broken again.
I could not check if the error is Python-related or not, as I found no way to retrieve/display the binary data in sqlcli, as it displays only something like 0x8002637A6F70652E6931 , but I doubt that this has something to do with Python.
Any clues of how to fix this?
My database version is Kernel 7.6.06 Build 003-121-202-135 | X32/LINUX 7.6.06 Build 003-121-20
2-135
Previously, I had 7.6.03 and updated it to the above version, hoping that this would fix the problem, but it did not.

Ok, first many thanks for your quick reply. I did not answer at first as the problem magically went away. But unfortunately the problem is back today.

The DDL statements look the following, there are no indexes on the table:

<pre>
CREATE TABLE torder (
 torderid INTEGER NOT NULL DEFAULT SERIAL,
 creation_date TIMESTAMP,
 transfer_date TIMESTAMP,
 signed_date TIMESTAMP,
 signed_with VARCHAR(3) CHECK (signed_with in ('TAN', 'BKU', 'MAN') OR signed_with IS NULL),
 revocation_date TIMESTAMP,
 done_date TIMESTAMP,
 formdata LONG BYTE NOT NULL,
 trans_function VARCHAR(30) NOT NULL CHECK (trans_function in ('do_bank_transfer', 'do_bank_collection',
 'do_cheque_transfer', 'do_cash', 'do_cashdraw')),
 trans_type VARCHAR(30) NOT NULL CHECK (trans_type in ('national','sepa','international')),
 applet_location VARCHAR(35),
 errors_text VARCHAR(100),

 PRIMARY KEY (torderid),
 FOREIGN KEY(customerid) REFERENCES kunde (kundeid),
 FOREIGN KEY(dbuserid) REFERENCES dbuser (dbuserid),
 FOREIGN KEY(torder_periodicid) REFERENCES torder_periodic (torder_periodicid)
</pre>

The insert statements look the following (They are copied out of the SQLAlchemy SQL log), one can see that the binary values are inserted here:

<pre>

All rows are inserted with binary data, so it's never NULL and it's also never set to an empty string ('').

But when reading back the rows, some binary values are an empty string.

The following Python code illustrates the problem:
<pre>
import sapdb.dbapi
def true_false_result(result):
 if result:
 return 'Bug begins'
 else:
 return 'Bug ends'
def check_bincols(bdb, sqlcmd):
 print "----
 print "QUERY: %s" % sqlcmd
 print "----
 bdbc = bdb.cursor()
 bdbe = bdbc.execute(sqlcmd)
 bug_occured = False
 stored_bin_result = False
 while 1:
 row = bdbe.fetchone()
 if row is None:
 break
Now check if the binary data results to an empty string,
This should never happen (= the database bug)
 bin_result = (row[7]() == '')
 if bin_result != stored_bin_result:
 bug_occured = True
 print "Toggle to %s at torderid %s" % (
 true_false_result(bin_result),
 row[0])
 stored_bin_result = bin_result
 if not bug_occured:
 print "No Bug for this query"
 bdbe.close()
 bdbc.close()
#bdb.close()
if __name__ == '__main__':
 bdb = sapdb.dbapi.connect('USER', 'PASS', 'DBNAME', 'LOCALHOST')
First try the original query, which results in a bug
 sqlcmd = 'select * from torder where customerid=1624 order by torderid desc'
 check_bincols(bdb, sqlcmd)
This query normally is bugfree
 sqlcmd = 'select * from torder where customerid=1624 order by torderid'
 check_bincols(bdb, sqlcmd)
This query has a bug, too
 sqlcmd = 'select * from torder order by torderid desc'
 check_bincols(bdb, sqlcmd)
But this one not
 sqlcmd = 'select * from torder order by torderid'
 check_bincols(bdb, sqlcmd)
This triggers the bug, too, which is curious as there's practically no ordering
 sqlcmd = 'select * from torder where customerid=1624 order by customerid desc'
 check_bincols(bdb, sqlcmd)
So, it seems that the bug occurs only when using "DESC" for descending
ordering.
</pre>

The output of this program is:

<pre>
QUERY: select * from torder where customerid=1624 order by torderid desc
Toggle to Bug begins at torderid 1355
Toggle to Bug ends at torderid 582
QUERY: select * from torder where customerid=1624 order by torderid
No Bug for this query
QUERY: select * from torder order by torderid desc
No Bug for this query
QUERY: select * from torder order by torderid
No Bug for this query
QUERY: select * from torder where customerid=1624 order by customerid desc
Toggle to Bug begins at torderid 1355
Toggle to Bug ends at torderid 582
</pre>

So, it can be seen that the problem occurs ONLY when using descending ordering. Moreover it's interesting that the result for "select * from torder order by torderid desc" is sometimes buggy, sometimes not, which seems to be related if someone inserted some more rows or not. What's furthermore interesting is the last query, as there the order is applied to "customerid", which is the very same for every row, so there is no ordering and the bug occurs here, too.

All this happens on my production instance. I have a testing environment, where I imported the very same data set (same database version etc.) and there is no such problem (for now), so it's quite complicated to nail down the problem further as I cannot easily disrupt the availability of the production instance.

All I could do for now is not to use the "DESC" command and reorder the data in my application, but that is really suboptimal as I have to keep all results in memory.

Any help is really appreciated!

Hermann Himmelbauer

Update: I tried the same query with the following code with C++ / SQLDBC (I modified one of the SQLDBC examples):

<pre>
First you have to include SQLDBC.h
#include "SQLDBC.h"
#include <stdio.h>
typedef struct ConnectArgsT {
 char * username;
 char * password;
 char * dbname;
 char * host;
} ConnectArgsT;
static void parseArgs (ConnectArgsT * connectArgs, int argc, char **argv);
using namespace SQLDBC;
Let start your program with a main function
int main(int argc, char *argv[])
 ConnectArgsT connectArgs;
 parseArgs (&connectArgs, argc, argv);
 char errorText[200];
Every application has to initialize the SQLDBC library by getting a
reference to the ClientRuntime and calling the SQLDBC_Environment constructor.
 SQLDBC_IRuntime *runtime;
 runtime = SQLDBC::GetClientRuntime(errorText, sizeof(errorText));
 if (!runtime) {
 fprintf(stderr, "Getting instance of the ClientRuntime failed %s", errorText);
 return (1);
 SQLDBC_Environment env(runtime);
Create a new connection object and open a session to the database.
 SQLDBC_Connection *conn = env.createConnection();
 SQLDBC_Retcode rc;
 rc = conn->connect(connectArgs.host, connectArgs.dbname,
 connectArgs.username, connectArgs.password);
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Connecting to the database failed %s", conn->error().getErrorText());
 return (1);
 printf("Sucessfull connected to %s as user %s\n",
 connectArgs.dbname, connectArgs.username);
Create a new statment object and execute it.
 SQLDBC_Statement *stmt = conn->createStatement();
 rc = stmt->execute("select * from torder where customerid=1624 order by torderid desc");
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Execution failed %s", stmt->error().getErrorText());
 return (1);
Check if the SQL command return a resultset and get a result set object.
 SQLDBC_ResultSet *result;
 result = stmt->getResultSet();
 if(!result) {
 fprintf(stderr, "SQL command doesn't return a result set %s", stmt->error().getErrorText());
 return (1);
Position the curors within the resultset by doing a fetch next call.
 while (1) {
 rc = result->next();
 if(SQLDBC_OK != rc) {
 break;
 //fprintf(stderr, "Error fetching data %s", stmt->error().getErrorText());
 //return (1);
 char szString[30];
 char szString1[3000];
 SQLDBC_Length ind;
Get a string value from the column.
 rc = result->getObject(1, SQLDBC_HOSTTYPE_ASCII, szString, &ind, sizeof(szString));
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Error getObject %s", stmt->error().getErrorText());
 return (1);
 rc = result->getObject(8, SQLDBC_HOSTTYPE_ASCII, szString1, &ind, sizeof(szString1));
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Error getObject %s", stmt->error().getErrorText());
 return (1);
 printf("%s %s\n", szString, szString1);
Finish your program with a returncode.
 return 0;
static void parseArgs (ConnectArgsT * connectArgs, int argc, char **argv)
setting defaults for demo database
 connectArgs->username = (char*)"USER";
 connectArgs->password = (char*)"PASS";
 connectArgs->dbname = (char*)"MYDB";
 connectArgs->host = (char*)"localhost";
use values from command line
 if (argc > 4) {
 connectArgs->host = argv [4];
 if (argc > 3) {
 connectArgs->dbname = argv [3];
 if (argc > 2) {
 connectArgs->password = argv [2];
 if (argc > 1) {
 connectArgs->username = argv [1];
</pre>

This works!! So it seems, that the problem is related to the Python module, which is interesting, as adding "DESC" should not be any difference to it. I personally suspect that there are some memory leaks in the code, which result in this strange behavior.

Any suggestions?

Losing the leading zero in binary values

Hi all,
I�m currently creating some basic examples of bitwise operations and I�ve just noticed that I�m losing the leadnig zero of a binary value ( e.g.
decimal 1 (expecting to see bin of 0001) is manifesting as 1
decimal 16 (expecting to see bin of 00010000) is manifesting as 10000
below is a full example
import static java.lang.Integer.*;
public class BitExample {
public static void main(String[] args) {
System.out.println(
     toBinaryString(0x1) + '\n' +
     toBinaryString(0x16) + '\n' +
     toBinaryString(0x6a) + '\n' +
     toBinaryString(0x80)
I can see I�m missing something, but not sure what. Can you help?
Many Thanks
Giles

which obviously returns a very different resultNo it does not ... let's translate the example to decimal (with additions instead of bitwise operations, but that doesn't change anything:
1234 +
0001
1235and
1234 +
1
1235both notations are correct, aren't they? Now the second one doesn't look so nice (and usually the 1 should be right-aligned to be easily readable, but it isn't wrong, because of this.
The same is true for binary operations. The problem is, that while learning bitwise operations it's easier to unserstand if you always write the leading zero (as you do in your example).

Binary Stored as String

Hi,
I am storing Binary Data into Varchar(Max) field, while migrating to another binary field, since it is stored earlier in the table with the varchar and then insert into Binary will again convert the string into Binary data. which is corrupting data.
How to Insert Varchar(max) field to Binary Field in another table
Thanks, Parth

Hi Parth,
Regarding your description, the binary data is stored in a varchar(max) column, do you mean the values of the varchar(max) column are like ‘0x5445535420535452494E47’? So when you tried to migrate it to a binary field, the string ‘0x5445535420535452494E47’
was converted into binary other than the value the string stands for?
If my understanding is correct, you may reference the code as below, just use the built-in
COVERT with one more optional parameter, you can read more details under
Binary Styles in the covert page.
DECLARE @srcTbl TABLE(str1 VARCHAR(MAX))
DECLARE @tarTbl TABLE(str1 VARBINARY(MAX))
INSERT INTO @srcTbl SELECT '0x5445535420535452494E47'
INSERT INTO @tarTbl SELECT CONVERT(VARBINARY(MAX),str1,1) FROM @srcTbl -- 1 here is necessary
SELECT str1 FROM @srcTbl
SELECT str1 FROM @tarTbl
If you have any question, feel free to let me know.

while (rset.next())
s= rset.getString("accid"); this line give me error
System.out.println (rset.getString("accid"));
System.out.println (s);

ADF7,
I'm not sure I understand what you are up to.
As far as I understand you want to get the display value instead of the index
I use this code
 public void StatusChangedListener(ValueChangeEvent valueChangeEvent)
 BindingContext lBindingContext = BindingContext.getCurrent();
 BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry();
 JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status");
 int newindex = (Integer) valueChangeEvent.getNewValue();
 Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!!
 Row lFromList = (Row) list.getValueFromList(newindex);
 Object lAttribute = lFromList.getAttribute("Value");
 String newVal = (String) lAttribute;
 }to get the value from a selectOneChoice component...

Determine which value of string is greater

Hi everybody,
I have a fairly complex problem which i hope you can help me with..
The solution is not probably not very hard (i assume), just hard to explain it but I'll give it a try.
I'm working with arrays. These arrays are "declared" as strings, see below:
                 String[] aa;
              aa= new String[5];
              String[] bb;
              bb=new String [5];
              String [] cc;
              cc=new String[5];The programs asks the "tester" to type in three random numbers (see code below)
System.out.println("First number:");
               aa=TextIO.getWord();
                    System.out.println("Second number:");
                    bb[i]= TextIO.getWord();
                              System.out.println("Third number");
                                   cc[i]=TextIO.getWord();
The program is then supposed to print the greater of the typed values.
eg. First number is greater._
How do i make the program to say which one of the three numbers (the numbers can be anything from 0 - 1000000) is greater?
Since the values are +"Strings,"+ I assume you just can't say
if aa > bb && aa > cc print("first number is greater") etc SO, i tried to write it like this:* (but ended up with the error: +"operator && cannot be applied to boolean,int"+
if (Integer.parseInt(aa) > Integer.parseInt(bb[i]) && Integer.parseInt(aa[i]) > Integer.parseInt(cc[i]))
                    correctanswer = Integer.parseInt(aa[i]);
               else if (Integer.parseInt(bb[i]) > Integer.parseInt(cc[i]) && Integer.parseInt(aa[i]))
                         correctanswer = Integer.parseInt(bb[i]);
                    else { correctanswer = Integer.parseInt(cc[i]); }
So the question is: How can i change the code (without changing the strings to int) so it will work?
I hope i have provided you with enough information, if not, please let me know.
Thanks

First off your array declaration is weird for strings. If you don't know the size of the string you are getting from the user then just declare your array like String aa = new String(). Leave it to an untold size!
Secondly, when you parse you are trying to parse a char. Characters already have an integer value. You need to parse the whole string.
Thirdly, when actaully getting the input from the user dump the parse into another variable...makes it easier.
ex: int firstNum = Integer.parseInt(aa) (when you declare it like I did above).
Fourthly, you need to check each greater than for every instance of the comparison. I.E.
if(a > b && a > c) {...}
if(b > a && b > c) {...}
if(c > a && c > b) {...}
Note: this goal can be accomplished dozens of different ways its up to you.
Quick fix: when you do this:
if (Integer.parseInt(aa) > Integer.parseInt(bb[i]) && Integer.parseInt(aa[i]) > Integer.parseInt(cc[i]))
                    correctanswer = Integer.parseInt(aa[i]);
               else if (Integer.parseInt(bb[i]) > Integer.parseInt(cc[i]) && Integer.parseInt(aa[i]))
                         correctanswer = Integer.parseInt(bb[i]);
                    else { correctanswer = Integer.parseInt(cc[i]); }
do this instead:
if (Integer.parseInt(aa) > Integer.parseInt(bb) && Integer.parseInt(aa) > Integer.parseInt(cc))
                    correctanswer = Integer.parseInt(aa);
               else if (Integer.parseInt(bb) > Integer.parseInt(cc) && Integer.parseInt(aa))
                         correctanswer = Integer.parseInt(bb);
                    else { correctanswer = Integer.parseInt(cc); }

Binary values corrupted in Content Manager

Hello,
When I copy and paste (or move) a content that has a property binary, in the second instance (the copy) these properties are corrupted. When I try to access to these properties, I receive the next exception:
com.bea.content.RepositoryException: No binary value could be found for property.
I'm working with WLPortal 10.3.
Is this a bug of Portal?
Is there any way to do this and the data are not corrupted?
Thanks.

When I copy or move there isn't exception, but when I access to the binary property of copy, it log this exception:
An error occurred while attempting to download the file. Use the browser back button to continue working.
