Using a Collection of beans to store a result set help.

Does anyone have any sample code on the subject? This is something I wrote up, but I wanted feedback, and also an example of how to retreive data out of the array of beans in jsp
package beanpersonal;
import beandatabase.DBConnection;
import java.sql.Connection;
import java.sql.SQLException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
import java.util.Collection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;
public class PersonNew {
public PersonNew() { }
public Collection getPersondata( String alias, String password ) {
Connection conn = null;
PreparedStatement stmt = null;
ResultSet rs = null;
Collection retValue = new ArrayList();
String query = "SELECT * FROM person WHERE (alias = ?, password = ?)";
try {
conn = DBConnection.getDBConnection();
stmt = conn.prepareStatement( query );
stmt.setString( 1, alias );
stmt.setString( 2, password );
rs = stmt.executeQuery();
while (rs.next()) {
PersonalInfo beanrow = new PersonalInfo();
beanrow.setAlias(rs.getString("alias"));
beanrow.setPassword(rs.getString("password"));
retValue.add(beanrow);
return retValue;
catch( SQLException sqle ) {
//sqle.printStackTrace();
//throw new ApplicationSpecficException("Cannot query db", sqle);
throw new RuntimeException(sqle);
finally {
try {if (rs != null) rs.close();} catch (SQLException e) {}
try {if (stmt != null) stmt.close();} catch (SQLException e) {}
try {if (conn != null) conn.close();} catch (SQLException e) {}
}

sorry i only view the codes, but don't read it as a whole maybe this codes can help you..

Can i store the Result set values as a Session variable

hai,
I want the result set values of a query to be used many times and I want the same resultset between different page calls.
I want all those records fetched from the database to be available in the next page with out refetching from the database.
can any one help me out. its very urgent.....
Thanks and regards,
Ravikiran
mail to me at : [email protected]

"can i store the Result set values as a Session variable "
Practically Yes u can
but u want be able to accesses it in other pages
u can try it and see
the other thing u can do is store the values from the resultset in a object say vector and put vector in seesion and u can use this any where
for e.g
Vector v=new Vector();
While(rs.next())
v.addElement(rs.getString(1));
v.addElement(rs.getString(2));
session.putValue("myVector",v);
now where u want to get it do this
Vector myvec=(Vector)session.getValue("myVector");
do do futher

Using RAW in Jave Bean to store data in Oracle 8i database

I have a question about using RAW in java program to read write data in Oracle database. Is there any sample with key information for me to refer to? Your help will be appreciated.
Jane Jane,
here is a code snippet provided by our QA team
hope it helps
Kuassi
1. Create the table:
"CREATE TABLE rawtable (key VARCHAR2(30), rawcol RAW(2000), longrawcol
LONG RAW, moredata VARCHAR2(100))"
2. Write the data:
byte x[] = {1,2,3,4,5};
byte y[]= {6,7,8,9,10};
PreparedStatement pstmtR =
conn.prepareStatement("INSERT INTO rawtable (key, rawcol,
longrawcol, moredata) VALUES (?, ?)");
pstmtR.setString(1, "rawcol data");
pstmtR.setBytes(2, x);
pstmtR.setNull(3, Types.LONGVARBINARY);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setString(1, "longrawcol data");
pstmtR.setNull(2, Types.BINARY);
pstmtR.setBytes(3, y);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setRAW(1, RAW_obj) can be used to insert the RAW data.
You can also use setBinaryStream to insert RAW data:
CallableStatement cstmt =
conn.prepareCall ("begin insert into rawtab values (?,?); end;");
cstmt.setBinaryStream (1, (java.io.InputStream) new
ByteArrayInputStream(rawbuf), rawbuf.length);
cstmt.setBinaryStream (2, (java.io.InputStream) new
ByteArrayInputStream(lrawbuf), lrawbuf.length);
3. Read the data:
InputStream is = null;
byte rawbuf [];
byte lrawbuf [];
ResultSet rset = stmt.executeQuery("SELECT rawcol, longrawcol FROM
rawtable");
// You can retrieve the data with the following methods
rawbuf = rset.getBytes(1);
lrawbuf = rset.getBytes(2);
RAW raw1 = rset.getRAW(1);
is = rset.getBinaryStream(column);
is = rset.getAsciiStream(column);
is = rset.getUnicodeStream(column);
When using CallableStatement:
((OracleCallableStatement)cstmt).registerOutParameter(1,
OracleTypes.RAW);

Using a variable in SQL to store intermediate results

I'm new to Crystal Reports, so pardon my ignorance.
I need to write a SQL statement in Crystal Reports (Ver. 11) that uses results from a query and stores them in a variable for further use in the statement. Something like this:
DECLARE @my_variable INT;
SET @my_variable=
CASE
                WHEN DATEPART (m,{?Date})<7
                THEN DATEPART (yyyy,( DATEADD (year,-1, {?Date})))
                ELSE DATEPART (yyyy,( DATEADD (year,0, {?Date})))
END
(Where {?Date} is a date parameter)
Is it possible to achieve this in the above form or some other form in Crystal Reports?
Thanks

Simple answer... When I used the variable, I marked it as a string. There is an email address setting.

How to Store the result sets of a stored procedure that is returning more that one result set in two different table ?

Hi Experts,
I have on stored procedure which returns mote than one resultset i want that to store in two different temp table how can achieve this in SQL server.
following is the stored procedure and table that i need to create.
create procedure GetData as begin select * from Empselect * from Deptend
create table #tmp1 (Ddeptid int, deptname varchar(500),Location varchar(100))
Insert into #tmp1 (Ddeptid , deptname ,Location )
exec GetData
create table #tmp (empid int , ename varchar(500),DeptId int , salary int)
Insert into #tmp (empId,ename,deptId,salary)
exec GetData
Niraj Sevalkar

You cant get two resultsets out of SP like this. The workaround is to merge and bring the resultsets.
For this number of columns as well as corresponding datatypes have to be compatible. Also you will need one additional column which indicates resultset value. Then use this as filter to get your desired resultset out
create procedure GetData as
begin
select 'resultset1' as Cat,*,.. N columns from Emp
union all
select 'resultset2' as Cat,*,.. N columns from Dept
end
create table #tmp1 (Ddeptid int, deptname varchar(500),Location varchar(100))
Insert into #tmp1 (Ddeptid , deptname ,Location )
Select column1,column2,column3
from OPENROWSET('SQLOLEDB','Data Source=Server_name;Trusted_Connection=yes;
Integrated Security=SSPI','Execute yourdb..GetData')
WHERE Cat = 'resultset1'
create table #tmp (empid int , ename varchar(500),DeptId int , salary int)
Insert into #tmp (empId,ename,deptId,salary)
Select column1,column2,column3, column4
from OPENROWSET('SQLOLEDB','Data Source=Server_name;Trusted_Connection=yes;
Integrated Security=SSPI','Execute yourdb..GetData')
WHERE Cat = 'resultset2'
also see
http://sqlblogcasts.com/blogs/madhivanan/archive/2007/11/26/select-columns-from-exec-procedure-name-is-this-possible.aspx
Another method is to populate table with relevant resultset within procedure itself and then select from the table directly outside.

SQL Query - store the result for optimization?

Good day experts,
I am looking for advice on a report. I did a lot of analytic functions to get core data that I need to make my report and its takes around 50 min for SQL to complete. Now with this data I need to create 3 different reports and I cant use the same SQL since there is a lot of agregation (example would be group by product in one case and by client in 2nd). For each of those different group bys I need a different report.
So how to create 3 reports from 1 SQL query without running the query 3 times?
First thing that comes to mind is to store the result set into a dummy table and then query the table since the core data I get is around 300 rows and then do different group bys.
Best regards,
Igor

So how to create 3 reports from 1 SQL query without running the query 3 times?
You already know the obvious answer - store the data 'somewhere'.
The appropriate 'somewhere' depends on your actual business requirements and you did not provide ALL of them.
MV - if the query is always the same you could use an MV and do a complete refresh when you want new data. The data is permanent and can be queried by other sessions but the query that accesses the data will be frozen into the MV definition.
GTT (global temp table) - if a NEW data load AND the three reports will ALWAYS be executed by a single session and then the data is NOT needed anymore then a GTT can work. The query that loads the GTT can be different for each run but the data will only be available for a single session and ONLY for the life of that session. So if anything goes wrong and the session terminates the data is gone.
First thing that comes to mind is to store the result set into a dummy table and then query the table since the core data I get is around 300 rows and then do different group bys.
That is commonly referred to as a 'REPORT-READY table'. Those are useful when the data needs to be permanent and available to multiple sessions/users. Typically there is a batch process (e.g. package procedure) that periodically refreshes/updates the data during an outage window. Or the table can have a column (e.g. AS_OF) that lets it contain multiple sets of data and the update process leaves existing data alone and creates a new set of data.
If your core data is around 300 rows you may want to consider a report-ready table and even using it to contain multiple sets of data. Then the reports can be written to query the data using an AS_OF value that rolls up and returns the proper data. You don't need an outage window since older data is always available (but can be deleted when you no longer need it.
If you only need one set of data you could use a partitioned work table (with only one partition) to gather the new set of data and then an EXCHANGE PARTITION to 'swap' in the new data. That 'exchange' only takes a fraction of a second and avoids an outage window. Once the swap is done any user query will get the new data.

Can we store result set in session..??

can we store result set object in session..??if yes ,,say i close the connection and use that result set object in some another page,,what happen if u call updateRow(),deleteRow() or insertRow()

You can store a result set object in session.
However you also have to keep that result sets connection open and dedicated to that result set.
In that scenario you will have a 1 db connection per session. Not very nice. And NOT recommended.
Once you close a ResultSet's connection then you shouldn't access the ResultSet. Simple as that.

How to get a collection of beans using web services

Hi,
I'm new to SOAP and Web Services I'd like to know whether the following is possible
or not.
I've created an EJB with this business interface:
public interface Users implements EJBObject {
public User[] getUsers( ) ...
Where the User object is a bean with some properties:
public User implements Serializable {
public void setName( ... ) ...
public String getName( ) ...
public void setAddress( ... ) ...
public String getAdress( ) ...
I've create the ejb-jar.xml and weblogic-ejb-jar.xml that contain the definition
of my EJB and then I try to deploy the web services using the ant task 'wsgen'.
I get the following exception:
org.xml.sax.SAXException: Could not find a codec that understood how to convert
class [LUser; using http://schemas.xmlsoap.org/soap/encoding/
: [ CodecFactory: http://xml.apache.org/xml-soap/literalxml=null, http://schemas.xmlsoap.org/soap/encoding/=null,
=null]
Can someone help to resolve this ? Also, I'd like to know if it's possible that
a web service return a collection of beans as shown above ?
Thanks for your help.
Ludovic.

Java beans are serialized/deserialized by the soap encoding codec
itself. you dont have to write custom encoders. I think the error
is because you dont have the java bean class on the server side.
Java bean class file should be in the classpath or it should be
added to the ejb jar file.
thanks,

You can do this. I guess, the problem is because you have
not defined a package for the bean.
Try something like:
package foo.bar;
class User{
I am attaching an example.

Using java beans to store records from recordset

Hi there,
I have been stuck on an issue with Java Beans in JSP for the last few days and cant get my head around it.
I am basically trying to retrieve all the records out of a resultset which pulls records from a table through a JDBC connection and store the records in a html table using the java beans getProperty tag.
Problem is that the first row of the recordset is being applied to every row in the table. I have tried implementing for loops to iterate through the result set but without any luck.
I need help urgently
Thank you

Thanks for the feedback M
I have added the JSTL 1.1 library and used the Foreach components and data source components which now totally eliminate the need for beans altogether. :P
<c:forEach var="row" items="${deejays.rows}">
<tr onmouseover="this.bgColor='gold';"
onmouseout="this.bgColor='#FFFFFF';">

How do I make a table of contents for a collection of six short stories that is after the legal page and NOT in the front on an unnumbered page?

How do I make a table of contents for a collection of six short stories that is after the legal page and NOT in the front on an unnumbered page?
When I first started I made a title page and then pasted in my first story from a .TXT file. After cleaning up I went back to the front a couple of empty lines ahead of the story and typed in the story title. Unlarged the font size and centered it, then

You can't do that. This is what the Pages User Guide, downloadable from your Pages Help menu, says:
Creating and Updating a Table of Contents
Each table of contents (TOC) you create using a Word Processing template lists only the content that follows it, up until the next table of contents. If you want a master table of contents for the entire document, it must be the only table of contents, and it must be at the beginning of the document.
You can do it manually though.

How to use BULK COLLECT, FORALL and TREAT

There is a need to read match and update data from and into a custom table. The table would have about 3 millions rows and holds key numbers. BAsed on a field value of this custom table, relevant data needs to be fetched from joins of other tables and updated in the custom table. I plan to use BULK COLLECT and FORALL.
All examples I have seen, do an insert into a table. How do I go about reading all values of a given field and fetching other relevant data and then updating the custom table with data fetched.
Defined an object with specifics like this
CREATE OR REPLACE TYPE imei_ot AS OBJECT (
recid NUMBER,
imei VARCHAR2(30),
STORE VARCHAR2(100),
status VARCHAR2(1),
TIMESTAMP DATE,
order_number VARCHAR2(30),
order_type VARCHAR2(30),
sku VARCHAR2(30),
order_date DATE,
attribute1 VARCHAR2(240),
market VARCHAR2(240),
processed_flag VARCHAR2(1),
last_update_date DATE
Now within a package procedure I have defined like this.
type imei_ott is table of imei_ot;
imei_ntt imei_ott;
begin
SELECT imei_ot (recid,
imei,
STORE,
status,
TIMESTAMP,
order_number,
order_type,
sku,
order_date,
attribute1,
market,
processed_flag,
last_update_date
BULK COLLECT INTO imei_ntt
FROM (SELECT stg.recid, stg.imei, cip.store_location, 'S',
co.rtl_txn_timestamp, co.rtl_order_number, 'CUST',
msi.segment1 || '.' || msi.segment3,
TRUNC (co.txn_timestamp), col.part_number, 'ZZ',
stg.processed_flag, SYSDATE
FROM custom_orders co,
custom_order_lines col,
custom_stg stg,
mtl_system_items_b msi
WHERE co.header_id = col.header_id
AND msi.inventory_item_id = col.inventory_item_id
AND msi.organization_id =
(SELECT organization_id
FROM hr_all_organization_units_tl
WHERE NAME = 'Item Master'
AND source_lang = USERENV ('LANG'))
AND stg.imei = col.serial_number
AND stg.processed_flag = 'U');
/* Update staging table in one go for COR order data */
FORALL indx IN 1 .. imei_ntt.COUNT
UPDATE custom_stg
SET STORE = TREAT (imei_ntt (indx) AS imei_ot).STORE,
status = TREAT (imei_ntt (indx) AS imei_ot).status,
TIMESTAMP = TREAT (imei_ntt (indx) AS imei_ot).TIMESTAMP,
order_number = TREAT (imei_ntt (indx) AS imei_ot).order_number,
order_type = TREAT (imei_ntt (indx) AS imei_ot).order_type,

last_update_date =

WHERE recid = TREAT (imei_ntt (indx) AS imei_ot).recid
AND imei = TREAT (imei_ntt (indx) AS imei_ot).imei;
DBMS_OUTPUT.put_line ( TO_CHAR (SQL%ROWCOUNT)
|| ' rows updated using Bulk Collect / For All.'
EXCEPTION
WHEN NO_DATA_FOUND
THEN
DBMS_OUTPUT.put_line ('No Data: ' || SQLERRM);
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line ('Other Error: ' || SQLERRM);
END;
Now for the unfortunate part. When I compile the pkg, I face an error
PL/SQL: ORA-00904: "LAST_UPDATE_DATE": invalid identifier
I am not sure where I am wrong. Object type has the last update date field and the custom table also has the same field.
Could someone please throw some light and suggestion?
Thanks
uds

I suspect your error comes from the »bulk collect into« and not from the »forall loop«.
From a first glance you need to alias sysdate with last_update_date and some of the other select items need to be aliased as well :
But a simplified version would be
select imei_ot (stg.recid,
                stg.imei,
                cip.store_location,
                'S',
                co.rtl_txn_timestamp,
                co.rtl_order_number,
                'CUST',
                msi.segment1 || '.' || msi.segment3,
                trunc (co.txn_timestamp),
                col.part_number,
                'ZZ',
                stg.processed_flag,
                sysdate
bulk collect into imei_ntt
from custom_orders co,
       custom_order_lines col,
       custom_stg stg,
       mtl_system_items_b msi
where co.header_id = col.header_id
   and msi.inventory_item_id = col.inventory_item_id

How to use same collection on two forms

Hi ,
My issue scenerio is--
I have two forms one is calling form other is call form. User will go to calling form and press button to open call form. In call form user will select some records. That records i want to store in collection. then user will close call form , and on calling form i want to use those collection values.
For this i did some coding like
I created a type in database , then I created a record type in which i stored selected records information. I can see that values have been properly stored in collection till i exit call form.
Once i am back on calling form it becomes null.
Please help..

Approach of using Bulk Collect

Hi Experts,
how to use bulk collect for uncertain number of columns of select statement.
Master table structure:
Create table tabmst
(id number,
cls_input varchar2(2000),
price number);
insert into tabmst(1,'select product, price from product',500);
insert into tabmst(2,'select product, price,purchase_dt from product',100);
insert into tabmst(3,'select * from product',1000);
Currently I want to store Select statement of cls_input column in a local variable like
dyn_qry:= cls_input; by using a cursor.
Now my question is how to use Bulk Collect by using "Execute Immediate" in Bulk collect variable as there is not certainity of the number of columns from "Select Statment". Please suggest.
Sample code:
I created TYPE variable for Bulk Collect also support blk_var;
Declare
dyn_qry varchar2(3000);
cursor c1 is select * from tabmst;
begin
for i in c1 loop
dyn_qry:= cls_input;
Execute immediate dyn_qry into blk_var;
End Loop;
End;
Now I want to store values of Each "Select statements columns" which is executing by dynamic SQL. but it is uncertain that how many columns with return from dynamic SQL.
Please suggest the approach on the same. Thanks in advance.

I don't think you can use bulk collect with EXECUTE IMMEDIATE. They do two different things. EXECUTE IMMEDIATE allows the execlution of dynamic SQL. BULK COLLECT provides optimization of SELECT statements when loading the contents into collections. I am not aware of any support for BULK COLLECT with EXECUTE IMMEDIATE.
You may be able to do this a different way. If you must use dynamic SQL (I suggest you don't unless it is absolutely necessary. Dynamic SQL is hard to write, hard to debug, hard to maintain, and hard to tune) use a reference cursor instead. You can use the BULK COLLECT with the standard fetch.
