Populating data from an array to a database

given a text file in the format like:
player1,p1,0,0,0
player2,p2,0,0,0
player3,p3,0,0,0
(Username,password,win,lost,draw) --
i use the readLine method of the BufferedReader obect to read each of the line . and then use the split(",") , the returned value of the split(",") is an array of that type , so given an database with an empty table "users", how can i use the SQL insert statement to put those data into a database, therefore there are three record in the databse . i spend quite a while to figure it out but fail : ) , can any one give me some hint? appreciated

Want JTree e.g. of populating data from database.

I want ur JTree example of populating data from database, can u plz give me that eg.?
Awaiting 4 ur reply.

Hi,
AFAIK, there is no direct approach to populate a JTree directly from a resultset. However, JTree can use a DOM tree as its model by using the adapter pattern. The procedure to do this is well-documented in the SUN website and the link is provided below. The code to convert a resultset to XML is provided below:
protected void resultSetToXML(OutputStream out,
ResultSet rs,
String stylesheet)
throws IOException, ServletException {
// Create reader and source objects
SqlXMLReader sxreader = new SqlXMLReader();
SqlInputSource sis = new SqlInputSource(rs);
// Create SAX source and StreamResult for transform
SAXSource source = new SAXSource(sxreader, sis);
StreamResult result = new StreamResult(out);
// Perform XSLT transform to get results. If "stylesheet"
// is NULL, then use identity transform. Otherwise, parse
// stylesheet and build transformer for it.
try {
// Create XSLT transformer
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t;
if (stylesheet == null) {
t = tf.newTransformer();
} else {
// Read XSL stylesheet from app archive and wrap it as
// a StreamSource. Then use it to construct a transformer.
InputStream xslstream = _config.getServletContext().
getResourceAsStream(stylesheet);
StreamSource xslsource = new StreamSource(xslstream);
t = tf.newTransformer(xslsource);
// Do transform
t.transform(source, result);
} catch (TransformerException tx) {
throw new ServletException(tx);
The classes SQLXMLReader and other classes used in this example are available in the following java packages.
import java.sql.*;
import javax.sql.DataSource;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.sax.*;
import javax.xml.transform.stream.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import org.xml.sax.helpers.AttributesImpl;
The following is the link that explains how to load a JTree from DOM.

Error while retrieving data from an ARRAY resultset

We hava an Oracle stroed procedure which has a table type as its OUT parameter and where the data is being entered into. This data requries to be returned to the Java client through a JDBC connection. We have used the OracleTypes' ARRAY object for this. We are facing errors when retieving data from the ARRAY resultset
The Oracle Package
----I created a table type called "PlSqlTable":
CREATE OR REPLACE TYPE PlSqlTable IS TABLE OF VARCHAR2(20);
----I defined this as the out parameter for my procedure :
PROCEDURE testSQL
arrayOutID OUT PlSqlTable
Then populated the object :
arrayOutID := PlSqlTable();
arrayOutID.extend(4);
arrayOutID(1):= 'Hello';
arrayOutID(2) := 'Test';
arrayOutID(3) := 'Ora';
----The procedure executes fine - all debug statements are printed ----right till the end of execution.
The Java class
----Here is how I have defined the parameters :
OracleCallableStatement stmnt = (OracleCallableStatement)connection.prepareCall("begin testSQL(?);end;");
stmnt.registerOutParameter(2,OracleTypes.ARRAY,"PLSQLTABLE");
System.out.println("Executing..");
stmnt.execute();
System.out.println("Executed..");
ARRAY outArray = stmnt.getARRAY(1);
System.out.println("Got array");
ResultSet rset = outArray.getResultSet();
System.out.println("Got Resultset..");
int i = 1;
while(rset.next()){
System.out.println("VALUE : " + rset.getString(i));
i = i+1;
----On execution, the debug messages display :
Executing..
Executed..
Got array
Got Resultset..
VALUE : 1
VALUE : Test
ERROR : java.sql.SQLException: Invalid column index
----But I have populated upto 3 values in th e procedure. Then why this error ?
PLLLEEEASE help me out on this.
Thanks, Sathya

haven't worked with db arrays but I think your problem is here:int i = 1;
while(rset.next()){
     System.out.println("VALUE : " + rset.getString(i));
     i = i+1;
}In the first loop you are retrieving the value from column 1(rs.getString(1)), which is OK, but in the second loop, you are trying to retrieve a value from the second column(rs.getString(2)) which doesn't exist. Try this code which only reads from column1:
while(rset.next()){
     System.out.println("VALUE : " + rset.getString(1));

Without loops how can i read data from associative Array??

Hi all,
I am facing scenario like...
i need to read data from associative array without using loops is it possible,
CREATE OR REPLACE PACKAGE BODY test_pkg IS
    TYPE t1 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
   -- in array we can expect more than one row or sometimes no data also.
FUNCTION test1(vt1 T1 DEFAULT CAST(NULL AS t1)) RETURN NUMBER IS
BEGIN
    -- basically in array we'll get data of column2
    -- this loop should satisfies table1.colum2 = nvl(NULL, table2.colum2 )if array is null.
    -- if array is not null then only compare with array values
    FOR i IN (SELECT t1.colum1,t1.column2
                     FROM table1 t1, table1 t2
                          WHERE t1.colum1 = t2.column1
                            AND t1.colum2 = nvl(vt1, t2.colum2)
      LOOP
        generateTEXT(i.colum1, i.colum2);
     END LOOP;
END test1;
END test_pkg;
in table1 we have date like...
colum1          column2
Jan                  1
Feb                  2
Mar                  3
if i call select test_pkg.test1(1) from dual then output should
be Jan..
and
select test_pkg.test1(null) from dual then it should display all elements from table1.
Jan                  1
Feb                  2
Mar                  3,
Thanks for your quick replay..

i need to read data from associative array without using loops is it possible,
No - you would need to create a SQL type and then use the TABLE operator to unnest the collection.
create or replace TYPE my_nums IS TABLE OF INTEGER;
DECLARE
-- TYPE my_nums IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
v_nums my_nums := my_nums(1, 2, 3);
v_total number;
BEGIN
select sum(column_value) into v_total from table(v_nums);
DBMS_OUTPUT.PUT_LINE
    ('Sum of the numbers is ' || TO_CHAR(v_total));
END;
Sum of the numbers is 6

I need to copy data from a table in one database (db1) to another table in

Hi
I need to copy data from a table in one database (db1) to another table in another database (db2).
I am not sure if the table exists in db2,,,if it doesnot it needs to be created as well data also needs to be inserted...
How am I supposed to this using sql statements..?
I shall be happy if it is explained SQL also...
Thanking in advance

How many rows does the table contains? There are manyway you can achieve this.
1. export and import.
2. create a dblink between two databases and use create table as select, if structure doesnot exists in other database, if structure exists, use, insert into table select command.
example:
create a dblink in db2 database for db1 database.
create table table1 as select * from table1@db1 -- when there is no structure present
-- you need to add constraints manually, if any exists.
insert into table1 select * from table1@db1 -- when there is structure present.
If the table contains large volume of data, I would suggest you to use export and import.

Buddy, it seems to me that you are describing data that belongs together -- a class. You are probably better off with one arraylist of objects of this class, each object having a String type variable, an int num variable, and a float price variable, make that a double price variable.
For examples of arraylists in action, please see the Sun java tutorials.

What is the best way to move data from one array to another

I'm going to be moving data from one array to a larger array on the same RAID but different controller. (I have some extra extra drives I'm also going to be installing Retrospect so I can't just restore from a backup.)
The RAID has 450GB of production files, fonts etc.
What is the best way to move the data over?
I saw that someone had suggested using ditto. Would that be better than MacMV?
I also own Bru LE so I could use that.
Any advice would be appreciated.
Thanks,
Paul

Ditto is a great option -- probably the best.

Extract data from XML file to Oracle database

Dear All
Please let me know, how to extract data from XML file to Oracle database which includes texts & images.
Thanking You
Regards Lakmal Marasinghe

I would do it from the database, but then again, I am a database / PL/SQL guy.
IMHO the database will deliver you with more options. I don't know about "speed" between the two.

Can we update the data from SSRS report to any database ?

Hi Team,
Greetings !!!!
Can we update the data from SSRS report to any database ?
Thanks,
Anand Gavle.

Nope SSRS doesnt have write back options. Its just a reporting tool
However one thing you can do is to link a webpage from SSRS report and do the changes through it
SSRS has the ability to navigate to web page through which you can capture any data inputs from users and save it to your db.

Adding data from an array to a table

How can i add information from an array to a table via JDBC? I have tried:
stmt.executeUpdate("INSERT INTO TEMP " + "VALUES (" + carData[0] + ", " + carData[1]);
but i get the error:
SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO statement.
Also, can i only add data to some columns of a row and not all?

If your TEMP table has only two columns and both of
them are of number
types, and your array contains only numeric types
(int[], long[] etc., it should not be a problem.
If your table contains more than two columns (and the
remaining columns are nullable) you need to list the
column names in the insert statement. Check your table
definition in the database and see SQL syntax for
insert.
If your columns are of string type, you need to
enclose the values in quotes (alternatively, use
PreparedStatement).I agree with this.
Here is the syntax that he was talking about
//if the values are numeric
stmt.executeUpdate("INSERT INTO TEMP(<COLUMN NAME>,<COLUMN NAME>) "
+ "VALUES(" + carData[0] + "," + carData[1] + ")";
//if the values are text
stmt.executeUpdate("INSERT INTO TEMP(<COLUMN NAME>,<COLUMN NAME>) "
+ "VALUES('" + carData[0] + "','" + carData[1] + "')";
Notice that the last part of your original query was incorrect. You forgot to put the bracket in quotes again.

Comparing data from an array

Hi all
I have a little problem regarding the use of arrays and obtaining the integer value from an index of one of the columns. I need to implement a program that reads data from serial ports. There are four serial ports and it is assumed that independant sets of data will be retrieved from each of these. I need my program to continuously loop and check to see if the data has changed at any of the serial ports (i've got this part working). The way it can be manually determined is if the file is opened and at the top of the data there is the error number which is incremented every time the data is changed. I have put the data into a 2D array for later use and have then put just the first column into a single array in the hope of bein
g able to convert it to an integer or some form that can be compared. I need the highest error number for each peripheral to be stored (probably need separate loops/case for each serial port? - multitasking?) and when the data is next sent, i need to be able to compare it to see if the error number has changed and if it hasn't just continue looping and if it has make the new value the highest (in which case the rest of the data needs to manipulated and automatically updated in the database). I have been thrown head first into this project and to this date had only been a casual Labview programmer (V6i)
Can anyone help?
Ive attached the snippet that is for comapring the data only if anyone can build upon it (or scrap it!)
Thanks
Ridge

To compare the error is easy,attached is a little modification to your vi with shift register and Array max and min function. I'm not sure if this is the only problem.

Unable to pull data from 2 tables of a database linked to a 2nd database

I have a Crystal V7 Report I'm upgrading to Crystal 10 or 11. It uses the following formula that works (data is in ONE MS Access database containing all three tables):
If {PayrollCalc.qSource}=0 then {AuthorizedWithholding.qDesc
else If {PayrollCalc.qSource}=1 or {PayrollCalc.qSource}= 2 then {UnionBenefitDetail.qUBDesc}
else
If {PayrollCalc.qSource}=4 then "Extra Tax" + {PayrollCalc.qID} else
If {PayrollCalc.qSource}=5 then "Payroll Insurance" else
If {PayrollCalc.qSource}=6 then {PayrollCalc.qID} else
Mid ({PayrollCalc.qID},2 )
The upgraded application software uses TWO SQL 2005 Express databases, replacing the one Access database. PayrollCalc is a table in database A while UnionBenefitDetail & AuthorizedWithholding are tables in database B. The links are left outer joined from PayrollCalc table to each of the others (I've tried all the enforcement options) but the formula no longer works. If I remark out the part of the formula from one or the other of the "extra" tables, then the one still active works great but I can't get both to work in the same subreport. There's no error, I just get a blank returned for the formula. I'm not familiar with using the Add Command so I haven't tried that. Can anyone help me?

I confirmed that the join fields are identical:
PRCalc Table - qConNo=int (32 bit), length 4
PRCalc Table - qID=varchar (byte), length 10
PRCalc Table - qSeg=int (32 bit), length 4
UnionBenefit Table - qUBID=varchar (byte), length 10
UnionBenefit Table - qUBSeg=int (32 bit), length 4
Both of these UnionBenefit fields are left outer joined FROM the PRCalc Table's qID & qSeg fields
Authorized Withholding - qConNo=int (32 bit), length 4
Authorized Withholding - qSeg=int (32 bit), length 4
These two fields are left outer joined FROM PRCalc's qConNo & qSeg fields.
The qDesc & qUBDesc fields that I'm trying to print in the same subreport using the formula that's not working are both varchar (bye), length 50 fields.
I have tried various other joins unsuccessfully. I'm convinced that the left outer join is the correct one to use since neither of the tables from Database B will always have records that match up with those in Database A (PayrollCalc's database). So yes, it appears that the left outer join does not work properly across two databases when more than one table in the 2nd database is used. It works fine if I just use one table from database B & do a separate subreport for the other table.

Retrieve data from a synonym in oracle database through db connect

Hi Everyone,
I have created certain synonym for some tables in oracle. I want to retrieve data from it through db connect but where through source system and then selecting database tables, only tables and views are available.
Synonyms are not available to create data sources and retrieve the data from it. Why is it so. Is this a limitation of db connect.
Can anyone please let me know about it.
Thanks,
Joshua.

Hi,
You want to import data from an external Oracle database into your BW 3.X. To do this, you can connect the external database to the BW 3.X release as a source system using the external database connect. BW 3.X here represents BW 3.0, BW 3.1 and BW 3.5 because in other (DB relevant) parts, all 3 versions are based on the same source code.
General information
The above function allows you to load data from an external Oracle database (not a BW database) into your BW 3.0 system.
There may also be constellations which cannot be used directly through the DB Connect access. However, it should be possible to find an adequate, customer-specific solution for most of these scenarios.
In such situations, the resulting work falls into the area of Consulting and cannot be handled via Support.
Successful implementation of a connection requires corresponding expertise and experience in the use of the source database in the areas:
                - Tools
                - SQL syntax
                - DB-specific functions
Corresponding knowledge of the source application is also required to ensure that semantically relevant data arrives in the BW system.
Procedure
You should execute the following steps to connect the source system (Q) to the BW system (BW):
Installing the client software on an BW application server
                     Of course, you only need to install the client software if you are using BW with a non-Oracle database.
                     Use the Oracle setup program on the database CD (runInstaller on Unix) to start the OracleInstaller. Follow the program instructions and the DB installation instructions to install the Oracle Client software on BW.
Testing connection setup from BW to Q
                     After you install the client software on BW, try to set up a connection from BW to the server on Q. You may need to adjust the tnsnames.ora or sqlnet.ora files for this, to introduce the Oracle systems (to which contact should be made) to BW. You can test the connection by executing the command "tnsping QDB" on BW to check whether the client has established contact to the QDB database on the Q system.
Creating a separate U user in Q
                     We recommend that you create a separate U user in Q for connection to BW. This means that authorization and administration questions can be solved centrally.
Displaying data sources in Q for the U user
                     To provide U data for users other than U, you can create views on other user tables as user U:
                     CREATE OR REPLACE VIEW viewname AS
                       SELECT * FROM QDB.tablename
                     You may have to grant SELECT privileges to user U in the QDB schema:
                        GRANT select ON QDB.tablename TO U
                     Of course, you can also restrict or reformat data in the view arrangement (for example, change from internal date format into the SAP date format). JOIN operations using several tables are also available.
                     !!! Synonyms do not yet work!!!
                     Synonyms that you can create as described below are another option for providing a complete table for the user U:
                       CREATE SYNONYM synoname FOR QDB.tablename
                     !!! Synonyms do not (yet) work!!!
                     After you have displayed the require data for user U, you can simply use
                       SELECT * FROM <view or table>
                     on the Q system to check which data is returned.
                     You can now open a link to Q as user U in the BW system with SQLPLUS and check, using the same SELECT, whether this data is also seen in the Oracle client. If this is not the case, there is probably a connection problem.

Solution
Supported BW, Basis and BW 3.0B database versions, Basis 6.20 Support Package 2 (or higher)
      Oracle 8.1 (or higher, see below)
Possible problems
- Synonyms do not (yet) work!
Up to now, only tables and views have been used as data sources for the DB Connect from the R3 Basis. As soon as synonyms are also used in the Basis, you will be able to convert created views (or even replicated tables) to synonyms as a workaround.
With Basis 6.40 at the earliest, therefore as of BW 3.5, you will also be able to use synonyms. Until then, the following will help:
CREATE VIEW <view_on_synonym> AS SELECT * FROM <synonym>
- The source DB must have at least the release version of the BW DB.
Oracle only ensures the support of client-server links if the version of the client is not higher than that of the server. So if BW has Oracle version 8.1 and, as in the case of Dbconnect, is run as a client against the server of the source database, the source database must have at least release Oracle 8.1 or higher.
Of course, you have the option to install the Oracle client software of a lower version and then use this for the DB connect. This is also the procedure used to work with a DB connect on external databases of other vendors.
Furthermore, the implementation of the DBconnect function in BW uses SAP Basis functions. Specifications of Oracle 8.1 database catalogs are used here. The source database must therefore have at least Version 8.1.
- Oracle Client Software Version
If you want to connect from an Oracle BW DB to an Oracle source DB, for the DB connect you naturally use the client software that you already installed on each application server.
If you want to connect from a non-Oracle BW DB to an Oracle source DB, check item 3 of note 521230 to see which Oracle client software version is released with your BW R3 kernel and use this version.
- Date and time fields in Oracle and their conversion into SAP-compatible column formats
Example with a DATE field:
Since a SAP table does not have a DATE field (date values are NUMC(8) and time specifications are NUMC(6)), we will use the Oracle DBA_TABLES system table as an example.
    SQL> desc dba_tables;
The Oracle DBA_TABLES system table has a LAST_ANALYZED field. This is a DATE type field and is recognized as a date field of 7 characters by DBA_CONNECT. However, the import does not work because the DATE is a 7-byte conglomerate of "...century, year, month, date, hour, minute and second." (extract from the Oracle documentation).
To make this DATE field legible for DB connect, you must use the TO_CHAR function in a VIEW. This should display the following examples:
SQL> select LAST_ANALYZED from dba_tables
      where table_name like 'RS%' and rownum < 10 ;
The formatting used here is the default used implicitly by SQLPLUS.
SQL> select to_char(LAST_ANALYZED,'YYYYMMDD') as dat from dba_tables where table_name like 'RS%' and rownum < 10 ;
The result now has the SAP compatible format YYYYMMDD and should be loaded correctly by the DB connect as a date.
SQL> select to_char(LAST_ANALYZED,'HH24MISS') as tim from dba_tables where table_name like 'RS%' and rownum < 10 ;
The result now has the SAP compatible format HHMMSS and should be loaded correctly by the DB connect as a time.
You can use the following example for more detailed experiments:
SQL> select to_char(
       TO_DATE('03-FEB-2001 04:05:06','DD-MON-YYYY HH24:MI:SS'),
       'YY-MM-DD HH24-MI-SS') as datim from dual;
with the result:
DATIM
01-02-03 04-05-06
When you create a VIEW and use the TO_CHAR function (or other functions), you should easily be able to avoid problems with the interpretation of date/time specifications (and other reformatting).
Details about the functions and the formats are contained in the Oracle documentation.
- Special characters
A words that contain special characters can only be imported correctly if the code pages in BW and in the source system are identical. If the code pages are not the same, DB Connect can be used if the characters to be imported appear under the first 127 characters of the character set.
The use of multibyte code pages in the source system for saving data using character sets with more than 256 characters (Kanji, Katakana, Hiragana, Korean, Chinese, Tagalog, Khmer, Arabic, Cherokee, and so on) can cause the characters to become corrupt.
For questions concerning the code pages, also refer to the FAQ note 606359 and question/answer 19 that appears there.
