Better way: No checkbox is selected, give an error
I have to give an error neither one of the 5 checkboxes are selected.
If cb1 <> "x" and
cb2 <> "x" and
cb3 <> "x" and
cb4 <> "x" and
cb5 <> "x".
write:/ 'Error'.
endif.
Is there a better way of doing this?
This isn't necessarily better, just different:
CASE space.
WHEN cb1 OR cb2 OR cb3 OR cb4 OR cb5.
WRITE:/ 'Error'.
ENDCASE.
I don't think this is what you want. It will return an error if any of them is un checked.

Interactive report gives an error only for a specific user
An interactive report based on a very complicated select gives an error only when a specific user is logged on.
The error is:
ORA-00932: inconsistent datatypes: expected - got CLOB.
For other users logging using this page it works fine.
Authentication for this application is done using a stored function.
The query does not use the current userid in it.
Why does it fail for a specific user? if there is a problem, it should fail all the time.Hi ankur,
By what you said the report dont have any date parameters or no date columns.
"Query execution was not successful ORA-01843 not a valid month." This means it is related with date mask passing a invalid month into date column or argument to to_date function.Check once the session date that is 'dd-mm-yy' or anything else
select * from nls_session_parameters where parameter = 'NLS_DATE_FORMAT'
select to_date('01-DEC-06'),to_date('01-12-06') from dual;
Also a general question whenever I am trying to mark any question as 'Helpful', the status is not changing. Is there anything I am missing.While you flag it 'helpful' or 'correct',it takes you to other screen where you see "Yes, the question is now answered" click the radio button and then click ok button.
Hope its helpful.
Best Wishes,
Kranthi.

A better way than a global temp table to reuse a distinct select?
I get the impression from other threads that global temp tables are frowned upon so I'm wondering if there is a better way to simplify what I need to do. I have some values scattered about a table with a relatively large number of records. I need to distinct them out and delete from 21 other tables where those values also occur. The values have a really low cardinality to the number of rows. Out of 500K+ rows there might be a dozen distinct values.
I thought that rather than 21 cases of:
DELETE FROM x1..21 WHERE value IN (SELECT DISTINCT value FROM Y)
It would be better for performance to populate a global temp table with the distinct first:
INSERT INTO gtt SELECT DISTINCT value FROM Y
DELETE FROM x1..21 WHERE value IN (SELECT value FROM GTT)
People asking questions about GTT's seem to get blasted so is this another case where there's a better way to do this? Should I just have the system bite the bullet on the DISTINCT 21 times? The big table truncates and reloads and needs to do so quickly so I was hoping not to have to index it and meddle with disable/rebuild index but if that's better than a temp table, I'll have to make do.
As far as I understand WITH ... USING can't be used to delete from multiple tables or can it?Almost, but not quite, as efficient as using a temporary table would be to use a PL/SQL collection and FORALL statements and/or referencing the collection in your subsequent statements). Something like
DECLARE
TYPE value_nt IS TABLE OF y.value%type;
l_values value_nt;
BEGIN
SELECT distinct value
BULK COLLECT INTO l_values
FROM y;
FORALL i IN 1 .. l_values.count
DELETE FROM x1
WHERE value = l_values(i);
FORALL i IN 1 .. l_values.count
DELETE FROM x2
WHERE value = l_values(i);
END;or
CREATE TYPE value_nt
IS TABLE OF varchar2(100); -- Guessing at the type of y.value
DECLARE
l_values value_nt;
BEGIN
SELECT distinct value
BULK COLLECT INTO l_values
FROM y;
DELETE FROM x1
WHERE value = (SELECT /*+ cardinality(v 10) */ column_value from table( l_values ) v );
DELETE FROM x2
WHERE value = (SELECT /*+ cardinality(v 10) */ column_value from table( l_values ) v );
END;Justin -
Can some one tell me a better way...
Hi All..
I work on a web application. I create user ids for people logging into my application. here I have a small problem.. This is what I am currently doing...
When I create a new user, I assign a new user id to the user and store all hi info.
All our user ids are stored in User_ID table and user info in User_Info table.
First I get the max user id from the User_Id table.
int iuserid = select max(User_ID) from User_ID;
Then I add ' 1 ' to this and assign it to new user.
iuserid = iuserid+1;
insert into User_id values(iuserid, <ssn> );
Then I store all user info in User_info table..
insert into User_info(iuserid, <first_name>, <last_name>,...);
Both these SQLs are executed as a transaction.
The problem that I have...
It works fine in a normal environment and in my testing.
But when the load inceases, before I insert into the User_info, another user tries to get the max User_id from User_ID table, then it conflicts..
I have seen occurences of User_Info storing the info of a different user against the User_id when many people are accessing the app at the same time.
Can some one tell me a better way to handle this scenario..
Appreciate all you help..
TIA..
CKHi,
assuming that the requirement for user_id is only for uniqueness (primary key requirement) not continuosly.
perhaps can try this,
1) create a table to keep the max id for each table's key.
e.g.
create table key_id_lookup
key_name char(n),
current_value number(m)
where n & m is the size of the field
2) for each creation of entry in the user_id table, lookup the value in the key_id_table and increment it after retrieval.
e.g. current_id = select current_value from key_id_lookup where key_name = 'user_id_key';
current_id+=1;
update key_id_lookup set current_value = current_id where key_name = 'user_id_key';
something similar to use of sequence if your database support it.
3) continue with the creation of record in other tables. now obtain the time stamp of creation and append with the current_id obtained. e.g. timestamp = 132456872; size of m is 5, user_id = 132456872 x 100000 + current_id;
this should give you a unique key at creation time.
There should be other better ways of resolving this(like locking the table for the update operation but affect performance, etc), depending on the feature supported by the database in use.
Hope this can help as last resort if other options not available. -
Better Way To Do This? Selector Operator...
I'm currently writing the selection operator for the algorithm. The aim of it is
to rate how the coursework block have been allocated and give there allocation
a rating...
How I have done it is have a method that searches through the one of the parent
timetables. It looks for coursework time blocks. Once it finds one it notes
this and looks at the next block along. If this is a coursework time block it
notes this as well. I then perform an operation comparing these two coursework
time blocks to find out if they are for the same Module. If they are not this
is not a very effective coursework timetable strategy.
Because of this I note in an array the the position of these two coursework time
block and give them a fitness rating of 1000. I then go on to see if the next
block is a coursework time block. If it is and its not of the same Module ID of
the two previous then I not these 3 block down in an array and give them a
fitness rating of 2000.
My concern is that I am using allot of if and for loop's and the code is
starting to look untidy at best. Is there any better way of doing this?
Below Is my code:
* @param parentOne
* @param parentTwo
public void selectionOperator(ArrayList parentOne, ArrayList parentTwo){
// Store's the fitness rating of sections of the timetable...
ArrayList parentOneBlockFitnessRating = new ArrayList ();
ArrayList parentTwoBlockFitnessRating = new ArrayList ();
//Loops through the timetable's timeblocks...
for (int i = 0; i < parentOne.size(); i++) {
//Checks to see if the current time block is of the class: CourseworkTimeBlock,
//if so it enters this statement...
if(parentOne.get(i).getClass().toString().equals("class Timetable.CourseworkTimeBlock")){
//A temp store for the current CourseworkTimeBlock...
CourseworkTimeBlock tempBlockOne = (CourseworkTimeBlock) parentOne.get(i);
System.out.println("Got Here!, Module ID...: " + tempBlockOne.getModuleId());
//Checks to see if the next time block along is of the class: CourseworkTimeBlock,
//if so it enters this statement...
if(parentOne.get(i+1).getClass().toString().equals("class Timetable.CourseworkTimeBlock")){
//A temp store for the next CourseworkTimeBlock...
CourseworkTimeBlock tempBlockTwo = (CourseworkTimeBlock) parentOne.get(i+1);
System.out.println("Got Here Aswell!");
//Checks to see if the current and next CourseworkTimeBlock module Id's
//are the same, if there arn't then this section is entered...
if(!tempBlockOne.getModuleId().equals(tempBlockTwo.getModuleId())){
//Checks to see if the second time block along is of the class: CourseworkTimeBlock,
//if so it enters this statement...
if(parentTwo.get(i+2).getClass().toString().equals("class Timetable.CourseworkTimeBlock")){
//A temp store for the second CourseworkTimeBlock along...
CourseworkTimeBlock tempBlockThree = (CourseworkTimeBlock) parentTwo.get(i+2);
//Checks to see if all 3 of the Module Id's of the CourseworkTimeBlocks match,
//if they don't match this statement is entered...
if(! tempBlockOne.getModuleId().equals(tempBlockTwo.getModuleId()) && (tempBlockTwo.getModuleId().equals(tempBlockThree.getModuleId()))) {
//ArrayList to store the fitness rating of the current block
//selection...
ArrayList <Integer> blockFitness = new ArrayList<Integer>();
//Position of first block.
blockFitness.add(i);
//Position of second block.
blockFitness.add(i+1);
//Position of second block.
blockFitness.add(i+2);
//Fitness Value
blockFitness.add(2000);
//Add block rating to main rating ArrayList...

parentOneBlockFitnessRating.add(blockFitness);
for (int o = 0; o < parentTwo.size(); o++) {
if(parentTwo.get(o).getClass().toString().equals("class Timetable.CourseworkTimeBlock")){
CourseworkTimeBlock tempBlockOne = (CourseworkTimeBlock) parentTwo.get(o);
System.out.println("Got Here!, Module ID...: " + tempBlockOne.getModuleId());
if(parentTwo.get(o+1).getClass().toString().equals("class Timetable.CourseworkTimeBlock")){
CourseworkTimeBlock tempBlockTwo = (CourseworkTimeBlock) parentTwo.get(o+1);
System.out.println("Got Here Aswell!");
if(!tempBlockOne.getModuleId().equals(tempBlockTwo.getModuleId())){

//Position of first block.
blockFitness.add(o);

blockFitness.add(o+1);
//Fitness Value
blockFitness.add(1000);
//Add block rating to main rating ArrayList...
parentTwoBlockFitnessRating.add(blockFitness);
}As you can see there are allot if statements and some bad coding practice to boot. But I don't know what other ways to do it....
Any directions of other ways how to do this?
Many Thanks
ChrisUnfortunately, I think you're stuck with a bunch of if-statements.
Fortunately, I have some things that may help you.
First, I usually make sure something is of x class via this
if (someObject instanceof SomeClass) {So, I'd adjust your 'class checking' conditionals from this
if(parentOne.get(i).getClass().toString().equals("class Timetable.CourseworkTimeBlock"))to this
if (parentOne.get(i) instanceof Timetable.CourseworkTimeBlock) {Secondly, your code logic is kind of confusing.
Why do you have a for-loop that iterates through every CourseworkTimeBlock, if you then (within each possible iteration) check iteration+1 and iteration+2? What happens if those throw an ArrayIndexOutOfBoundsException, or are null? -

I would like to create above query in function so that return value would be used in
another query select statement and I am using SQL 2005.
I would like to know if there is a way to make this work as a function or any better way
to achieve this?
Thanks,This very simple: We cannot use dynamic SQL from used-defined functions written in T-SQL. This is because you are not permitted do anything in a UDF that could change the database state (as the UDF may be invoked as part of a query). Since you can
do anything from dynamic SQL, including updates, it is obvious why dynamic SQL is not permitted as per the microsoft..
In SQL 2005 and later, we could implement your function as a CLR function. Recall that all data access from the CLR is dynamic SQL. (here you are safe-guarded, so that if you perform an update operation from your function, you will get caught.) A word of warning
though: data access from scalar UDFs can often give performance problems and its not recommended too..

Hi Raju,
Can you help me writing CLR for my above function? I am newbie to SQL CLR programming.
Thanks in advance!

Time difference by date by time range - a better way?
Someone suggested this is a better place for my question:
Hi
I need to display the difference in time - every day for different time ranges,
Example 1-2 pm, 4-5 pm, 7-8 pm. And I need the time difference in 2 dates in the past week for each of these ranges everyday.
example
Date Diff Range
01/01/2007 00:01 1-2pm
01/02/2007 00:03
01/03/2007 00:10
01/04/2007 00:05
01/05/2007 00:23
01/01/2007 00:10 4-5pm
01/02/2007 00:13
01/03/2007 00:11
01/04/2007 00:15
01/05/2007 00:23
01/01/2007 01:10 7-8pm
01/02/2007 00:13
01/03/2007 00:10
01/04/2007 00:11
01/05/2007 00:21
One way to achieve this is to have multiple unions for each day and each time range.
Example:
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
union
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
union
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
This will give me the required information for only one day - and that is for sysdate-5.
I will have same nyumber of unions for each day.
Is there a better way to accomplish the same?
Any help appreciated.
Thx!Hi
Sorry for the late response but better late than never:::
I have gotten the answer of getting data for previous 5 days. I have changed the time between statement and is given below(*).
Here is a reply to all the questions you had asked in response to my questions.
What data you have? What parameters are you going to input?
I have already given sample data in my post.
There are no input parameters.
You are talking about the difference - between what is this difference?
Difference is the difference between 2 timestamp datatypes in 2 different tables (as you may see in the query)
The field diff - is it varchar2 like '1-2 pm' or what?
I didnt understand your question. What do you get when you subtract two timestamp datatypes - that should be the datatype - if I have understood your question. Not sure if thats what you asked.
But IMHO it's impossible to get such a result, of course, if dt_tm in the query is the same as Date in the result!
The time components in the queries are different. If you see:
1st Query:...
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
2nd Query:....
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
3rd Query:
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
First should be between 1 and 2 pm for sysdate-5.
I need starting previous 5 days till sysdate.
Second is between 4 and 5 pm again for sysdate-5.
I need starting previous 5 days till sysdate.
Same with 3rd.
My final query is something like this:
select t1.dt_tm, count(t1.id), '1 - 3 am' as period
from table1 t1, table2 t2
where t1.id = t2.id
and dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
group by t1.dt_tm
union
select t1.dt_tm, count(t1.id), '4 - 5 pm' as period
from table1 t1, table2 t2
where t1.id = t2.id
and dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
group by t1.dt_tm
union
select t1.dt_tm, count(t1.id), '7 -8 pm' as period
from table1 t1, table2 t2
where t1.id = t2.id
and dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
group by t1.dt_tm
I need for the last 5 days and what i can think of is have 5 different queries for past 5 days and 3 queries per day for the 3 different time periods. This would mean 15 queries. Was wondering if there is a better way to achieve the same?
Any help appreciated.
Thx! -

Time difference issue - need a better way
Hi
I need to display the difference in time - every day for different time ranges,
Example 1-2 pm, 4-5 pm, 7-8 pm. And I need the time difference in 2 dates in the past week for each of these ranges everyday.
example
Date Diff Range
01/01/2007 00:01 1-2pm
01/02/2007 00:03
01/03/2007 00:10
01/04/2007 00:05
01/05/2007 00:23
01/01/2007 00:10 4-5pm
01/02/2007 00:13
01/03/2007 00:11
01/04/2007 00:15
01/05/2007 00:23
01/01/2007 01:10 7-8pm
01/02/2007 00:13
01/03/2007 00:10
01/04/2007 00:11
01/05/2007 00:21
One way to achieve this is to have multiple unions for each day and each time range.
Example:
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
union
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
union
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
This will give me the required information for only one day - and that is for sysdate-5.
I will have same nyumber of unions for each day.
Is there a better way to accomplish the same?
Any help appreciated.
Thx!Time difference by date by time range - a better way?

Thanks for posting the CREATE TABLE and INSERT statments. Remember why you go to all that trouble: so the people whop want to help you can re-create the problem and test their ideas. When you post statemets that don't work, it's just a waste of time.
None of the INSERT statements for tab2 work. Tab2 has 6 columns, but the INSERT statements only have 5 values.
Please test your code before you post it.
I need to get all rows from tab1 that does not match tab2 WHat does "match" mean in this case? Does it mean that tab1.ref_cd = tab2.ref_cd?
and any row from tab1 that matches ref_cd in tab2 but key is different.
Existing Query
select
ref_cd,
key
from
select
ref_cd,
key
from
tab1, tab2
where
tab1.ref_cd = tab2.ref_cd and
tab1.key <> tab2.key
union
select
ref_cd,
key
from
tab1
where
not exists
select 1
from
tab2
where
tab2.ref_cd = tab1.ref_cd
Does that really work? In the first branch of the UNION, you're referencing a column called key, but both tables involved have columns called key. I would expect that to cause an error.
Please test your code before you post it.
Right before UNION, did you mean
tab1.key != tab2.key? As you may have noticed, this site doesn't like to display the <> inequality operator. Always use the other (equivalent) inequality operator, !=, when posting here.
I am sure there will be an alternate way to write this query in better way. Appreciate if any of you gurus suggest alternative solution.Avoid UNION; it can be very inefficient.
Maybe you want something like this:
SELECT tab1.ref_cd
, tab1.key
FROM tab1
LEFT OUTER JOIN tab2 ON tab2.ref_cd = tab1.ref_cd
WHERE tab2.ref_cd IS NULL
OR tab2.key != tab1.key

A better way to run a 7 day report?
Using Crystal Reports 11
I am hoping there is a better way of running a seven day report that i have to run weekly
In the report i have it set when refreshing the document, the "Prompt for new parameter values" comes up and there is a date field for start and end
This is how i did it
I made a formula called "Date" this comes from the closed date of our accounts
I made a Parameter Field "Start Date" with the TYPE field is "Date"
I made a Parameter Field "End Date" with the TYPE field is "Date"
I made a Select Expert Using data from the "ClosedDate" in the first drop down I picked "Formula" and used this as the formula
{WH_ACCTCOMMON.CLOSEDATE} in {?Start Date} to {?End Date}
Two things
1. Is there a way to have "Prompt for new parameters values" as the default checked off box when clicking "Refresh"?
2. Is there a way to only enter a start date and the refresh would just run 7 days without entering a end date?Hi,
Here's a suggestion for question 1:
When you preview the report for 1st time there is no prompt window that asks you to select whether you wish to 'Use current values' or 'Prompt for new values'.
If the Preview window is open and you hit refresh again, this is when you get the pop-up with the above options. If you close the Preview window and refresh again, you would not get a pop-up and it will show the Prompt window instead.
For question 1, you can follow Alun's sugestions.

A better way to do ChangeListeners?
I find myself having to implement multiple change listeners in a single class, and I was wondering if there was a way to do this that wouldn't trigger compilation problems. For example, let's say you have a LineChart, and you want the chart to listen for changes to the data, but also changes to the user's smoothing algorithm selection. You might try declaring your class like this:
public class MyGraph implements DataChangeListener, SmoothingChangeListener {....where you've declared DataChangeListener, and SmoothingChangeListener as
DataChangeListener extends ChangeListener<SomeDataStructure>{...}
SmoothingChangeListener extends ChangeListener<ISmoothable>{...}The compiler will tell you immediately that MyGraph can only implement one ChangeListener.
In real life, I have classes that have to listen for multiple types of events, and both for the sake of semantic clarity and for the sake of feasibility, they need to implement those change listeners. I've used event buses in certain cases, but they tend to obscure what the class is actually listening to.
Is there a better way of doing this?Event handling code is, almost by definition, controller code. So it makes sense (to me at least) to have event handling code in the controller. You can put the code I showed previously
someDataSeries.dataProperty().addListener(new ChangeListener<...>() {
public void changed(...) {
someChart.animatedProperty().addListener(new ChangeListener<Boolean>() {
public void changed(...) {
});directly in your controller. (I suppose I thought "MyGraph" was your controller, though the name should have implied otherwise to me.)
However, if you really want to have the event handlers defined elsewhere, you can still do so, while using anonymous inner classes (or lambdas when we all upgrade next September):
public class MyGraph {
private final ChangeListener<SomeDataType> dataListener = new ChangeListener<SomeDataType>() {
@Override
public void changed(...) { ... }
private final ChangeListener<ISmoothable> smoothingListener = new ChangeListener<ISmoothable>() {
@Override
public void changed(...) { ... }
public ChangeListener<SomeDataType> dataListener() { return dataListener ; }
public ChangeListener<ISmoothable> smoothingListener() { return smoothingListener ; }
}and you can then do
dataSource.addListener(myGraph.dataListener());
smoothingProperty.addListener(myGraph.smoothingListener());But I recommend the approach I first suggested: I use this all the time. -
A better way to initialize imported taskflows and BCs with current user
Hello.
I'm currently developing a composite application containing one main application and a number of subapplications (modules) packed in adflibs.
Main application has a side menu and a dynamic region, showing taskflows (on fragments) from adflibs.
Main application is configured with adf security and it has current login and queries his ID. I would like main application to tell modules current user ID rather than each module to find out current user on their own.
So there is currentUserID input parameter required in each imported taskflow. And my question is what is a better way to process this ID in the modules?
What I have previously done is:
I've created a custom BC classes layer, VOImpl and VORowImpl have getIdUser() method. This method reads currentUserID parameter from pageFlowScope where the taskflow is storing the parameter.
Top-level View Objects have :IdUser query parameter and corresponding bind variable. This bind variable has value="source.getIdUser()", calling the method from custom VO class.
This way works fine but here and there I read that it is a bad practice to access pageFlowScope from BCs.
I could agree with this in case someone could share a better way.
So what is a good practice?
Thanks.
ADF/JDev 11.1.2.3 - 12Why don't you use adf security for this? Read Oracle ADF: Security for Everyone which give you an overview and sample on how to implement this.

where does the sql stuff excute in the following stored procedure, directly in the database or it goes through the oracle VM first ?

PreparedStatement st = conn.prepareStatement("select from table where col=?");
st.setString(1,"value");
ResultSet rs = st.execute();
and is there a better way to read and parse an xml document with PL/SQL.what i've read about is the ability to parse an XML file to load its data directly into a database table.What i was looking for was just a way to parse XML without having to load any data into tables so i did it with java.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "CustomParser" AS
import javax.xml.prasers.SAXParser;

}PLSQL does not go through Java to access the database. The actual access to the database is via the same mechanism for both, so in some sense, both perform about the same. However, PLSQL datatypes have the same representation as database datatypes so there is no conversion. Java datatypes have different representations than database datatypes so there is a conversion cost associated with moving data between Java and the database.
If your processing is simple and you are moving a lot of data, PLSQL is likely the better choice. If your processing is more complex and you are moving less data, Java is likely the better choice. There are other things such as portability you should consider, but the amount of data and complexity of the code are the first considerations.

A better way to generate the needed XML?
I am working on a 10.2 system and looking to see if there is a better way to generate the resulting XML than what I have come up with. Here is a test case and the output it generates. I don't really like querying the table for each column needed as the real table has eight columns I am pulling. I would like to make one pass on person_h and get the info needed instead of making eight passes, but not sure if it is possible.
with person_h as
(select 1 id, 'M' gender, 'W' race, '170' weight from dual union all
select 1, 'M', 'W', '170' from dual union all
select 1, 'M', 'W', '180' from dual union all
select 1, 'M', NULL, '175' from dual union all
select 1, NULL, 'W', NULL from dual
select xmlelement("Person",
(select xmlagg(xmlelement("Sex", gender))
from (select distinct gender
from person_h
where id = 1
and gender is not null) pg),
(select xmlagg(xmlforest(race as "Race"))
from (select distinct race
from person_h
where id = 1) pg),
(select xmlagg(xmlforest(weight as "Weight"))
from (select distinct weight
from person_h
where id = 1) pg)
).getstringval()
from dual;
Output
<Person>
<Sex>M</Sex>
<Race>W</Race>
<Weight>170</Weight>
<Weight>175</Weight>
<Weight>180</Weight>
</Person>Note: Previously posted on the XML DB forum at A better way to generate the needed XML? but still looking for other solutions so putting in front of more eyes here. I have considered using a WITH statement to do the initial query on person_h but haven't tested that yet to see what Oracle really will do as just getting back around to this lower priority task of mine.I'm using the WITH statement to simulate a table and DUAL/UNION ALL to create data in that "table". I've seen it used plenty of times in this forum so not sure why a problem for this example. The actual SQL/XML statement hits that "base table" three times, so I didn't include all eight columns because three columns is sufficient to show the problem in the way I coded the SQL. Following the SQL is the sample OUTPUT that SQL statement generates and that is the output I created and need. I'm just looking for other options to achieve the listed output.
