Hi All,
Please look into the above data, If analytic function LAG(),CASE expression are possible to locate the cursor position in the single query, then any one can help me out about it. I tried but could not.
Regards,
Neel.

You can do this with the SUM analytic function. Taking the emp table, for example,
1 select ename, sal, SUM(sal) OVER (order by empno)
2    from emp
3* order by empno

How can I write this query In parameterize form so That I can prevent sql Injection

String strQry = "INSERT INTO tblVoucherType (VhrTypeCode,moduleCode,transCCode,"
+ "voucherType,OrderNumber,active,AccountId) "
+ " values('" + txtVhrCode.Text + "','" + ddlModule.SelectedValue.ToString() + "',"
+ "'" + ddlTrans.SelectedValue.ToString() + "','" + txtVhrName.Text + "','" + btnRadio.SelectedValue + "'"
+ ", '" + status.Checked + "', '" + txtAccount.Text + "')";

Basically it will look like:
String strQry = "INSERT INTO tblVoucherType (VhrTypeCode,moduleCode,transCCode, ...)"
+ " values(@VhrCode, @moduleCode, @transCCode, ....)";
sqlCommand.Parameters.AddWithValue("@VhrCode", txtVhrCode.Text );
sqlCommand.Parameters.AddWithValue("@moduleCode", ddlModule.SelectedValue.ToString() );
sqlCommand.Parameters.AddWithValue("@transCCode", ddlTrans.SelectedValue.ToString() );
.. and so on
sqlCommand.ExecuteNonQuery();

How can i improve this query.

Hi guys i am beginner , just wanted to know some info , how can i improve this query ..
select *
from tableA A, viewB B,
where A.key = B.key
and a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
one more thing should function should be on left side of equal sign.
will a join make it better or something else is needed more than that .

will a join make it better or something else is needed more than that .If you are a beginner try to learn the ANSI Syntax. This will help you a lot to write better queries.
Your select would look like this in ANSI.
select *
from tableA A
JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_function(a.key);The good thing here is that this separates the typical joining part of the select from the typical filter criteria.
The other syntax very often let you forget one join. Just because there are so many tables and so many filters, that you just don't notice correctly anymore what was join and what not.
If you notice that the number of column is not what you expect, you can easiely modify the query and compare the results.
example A
Remove View B from the query (temporarily comment it out).
select *
from tableA A
--JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
example B
You notice, that values from A are missing. Maybe because there is no matching key in ViewB? Then change the join to an outer join.
select *
from tableA A
LEFT OUTER JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)(The outer keyword is optional, left join would be enough).

List v = new Vector() how can i write this ?

List v = new Vector() how can i write this ?
vector does not 'extends' List rather it 'implements' only ......so how can write this way ? ( polymorphism applies only for 'extends' ).

my question in a simple way is :
List some_list extends Vector
No, List is an interface; Vector is a concrete class. Read the javadocs.
Vector implements List
>
AND
List some_list implements Vector
are these two same in behaviour
our apart from theoretical differences ?thanks
Interfaces don't have any implementation; they're pure method signatures. When a concrete class implements an interface, it makes a promise that says "I will provide implementations for exactly these methods. Any client can call a method from the interface and I will do something 'sensible' if I'm written correctly."
From the point of view of static and dynamic types, there's no difference between interfaces and classes.
C++ has interfaces, too - they're classes with all pure virtual methods. If you understand how C++ works, the concept shouldn't be hard.
ArrayList is preferred precisely because it isn't synchronized by default. (You can always make it so using java.util.Collections if you wish later on.) If you don't need synchronization, why pay the performance penalty?

Well, at least you tried and got some of it right.
I think this should do what you want, but my C is rusty. Is the increment performed before or after the loop executes? If it's after, then I believe the loop should iterate 11 times, not 10.
In any case, you should note that for a literal translation, you would need to add a sequence structure to guarantee that Y was written to only after the inner loop finished because of the way data-flow works.. Also, note that controls and indicators in LabVIEW are not equivalent to variables. They can be used as such, but they usually should not be.
Another point about this is that you probably want to use the correct data type - the orange terminals are floating point indicators (of double precision, in this case) and you want integers.
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.

Can anyone tell me how can i optimize this query ??? :
Select Distinct eopersona.numident From rscompeten , rscompet , rscv , eopersona , rscurso , rseduca , rsexplab , rsinteres

PLEASE IF YOU FIND SOMETHING WRONG.. PLEASE HELP ME.. this query takes me aproximatelly 10 minutes and the database is really small ( with only 200 records on each table )

You are querying eight tables, however in any of your OR predicates you're only restricting 3 or 4 of those tables. That means that the remaining 4 or 5 tables are generating cartesian products. (n.b. the cartesian product of 5 tables with 200 rows each results in g 200^5 = 320,000,000,000 rows) Then you casually hide this behind "distinct".
A simple restatement of your requirements looks like this:
Select eopersona.numident
From rscompeten,
       rscompet,
       rscv,
       eopersona
Where LOWER (rscompeten.nombre) LIKE '%caracas%'
   AND rscompeten.id = rscompet.idcompeten
   AND rscv.id = rscompet.idcv
   AND eopersona.id = rscv.idpersona
UNION
Select eopersona.numident
From rscurso ,
       rscv,
       eopersona
Where LOWER (rscurso.nombre) LIKE '%caracas%'
   AND rscv.id = rscurso.idcv
   AND eopersona.id = rscv.idpersona
UNION
Select eopersona.numident
From rscurso ,
       rscv,
       eopersona
Where LOWER (rscurso.lugar) LIKE '%caracas%'
   AND rscv.id = rscurso.idcv
   AND eopersona.id = rscv.idpersona
UNION
...From there you can eliminate redundancies as desired, but I imagine that the above will perform admirably with the data volumes you describe.

How would I write this query

[USERNAME]
[GROUP]
User1
New Member
User2
New Member
User1
All Members
User1
Gold Member
How would I write a query so that I could select * from the above table where a user has more than 1 group (user1) and if one of the groups = 'All members' then ignore that row and just return the all the other rows for the user that has > 1 group.
Thanks in advance. I can write the query for counting if a user has more than 1 group, but I stuck on the rest.
Thanks again

Try this
declare @tab table(USERNAME varchar(10), Usergroup varchar(15));
insert into @tab values
('User1','New Member'),
('User2','New Member'),
('User1','All Members'),
('User1','Gold Member');
select * from
(Select *,ROW_NUMBER() OVer(partition by username Order by case when Usergroup ='All members' then 0 else 1 end desc) RN From @tab ) t
where t.usergroup= case when t.rn >1 and t.Usergroup='All members' then 'Do not return' else t.Usergroup end

How can I write this string to a file as the ASCII representation in Hex format?

I need to convert a number ( say 16000 ) to Hex string ( say 803E = 16,000) and send it using Visa Serial with the string control in Hex Mode. I have no problem with the conversion (see attached). My full command in the hex display must read AA00 2380 3E...
I can easily get the string together when in Normal mode to read AA0023803E... but how can I get this to hex mode without converting? (i.e. 4141 3030 3233 3830 3345 3030 3030 3031 )

Sorry, The little endian option was probably introduced in 8.0 (?).
In this special case it's simple, just reverse the string before concatenating with the rest.
It should be in the string palette, probably under "additional string functions".
(note that this only works in this special case flattening a single number as we do here. If the stat structure is more complex (array, cluster, etc.) you would need to do a bit more work.
Actually, you might just use typecast as follows. Same difference.
I only used the flatten operation because of the little endian option in my version.

These errors typically occur when security software interferes with the restore and update process. Use the steps to troubleshoot security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See the steps under the heading "Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store." If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

How can i run this query in BI Answers

Hi,
pls tell me how can i run this sql statement in BI Answers....???
select abc_date,abc_asset_desc,sum(nvl(abc_market_val_lcy,0)+nvl(abc_accr_lcy,0)) "total balance" from abc
group by abc_date,abc_asset_desc;any help would be appriciated.... :-)
Regards

Strange question this one.
normally with Answers you pick the columns you want to report on and the BI server will construct the SQL for you.
In this example you would need a star with the abc dimension logical table and a logical fact for abc (these can be in the same table), which has a calculated field for 'Total Balance'.
You then pick the columns you require and Answer and the BI will automatically add the group by.

I do work with forms developer very much. Sql knowledge is as oracle sql book(cerfitication 9i). But this type of sql isn't available there.
where can i learn this type of sql ? Different sql then ordinary ?Certification is a different topic entirely.
There are books and web sites dealing with more advanced techniques. Sorry, I don't know any well enough to recommend them. Some authors (such as Tom Kyte) are consistently good.

How can i make this query run for a form

This query works fine for a sql report
SELECT *
FROM STUDENTS
WHERE given_name||' '||family_name = :P101_USERNAME
AND password = :P101_PASSWORD;
But i want it to do the same thing for a form but i dont have the option like i do for the report where i can just apply the condition to the process.
Anyone any ideas how i could do this so that when i go to the form this information is already there based on the username and password from the previous page?

Assuming that page 101 is your login form, just lookup the primary key of the student based on the values presented in the login page fields, then set and pass this value to the form page.
So you would create a process that runs near the very end of the the login processes on page 101, something like this:
declare
l_student_id students.student_id%TYPE;
begin
select student_id into l_student_id from students where given_name||' '||family_name = :P101_USERNAME and password = :P101_PASSWORD;
-- then set the value of your form page primary key field
:P1_STUDENT_ID := l_student_id;
end;I've done something similar and it works fine for me, although I haven't looked at it recently.

2 ideas:
1. Inline function to perform the CASE funcionaltity for you
2. Piplelined function to generate the entire dataset

Hi All,
The below query is taking more time to run. Any ideas how to improve the performance by rewriting the query using NOT EXITS or any other way...
Help Appreciated.
/* Formatted on 2012/04/25 18:00 (Formatter Plus v4.8.8) */
SELECT vendor_id
FROM po_vendors
WHERE end_date_active IS NULL
AND enabled_flag = 'Y'
and vendor_id NOT IN ( /* Formatted on 2012/04/25 18:25 (Formatter Plus v4.8.8) */
SELECT vendor_id
FROM po_headers_all
WHERE TO_DATE (creation_date) BETWEEN TO_DATE (SYSDATE - 365)
AND TO_DATE (SYSDATE))
Thanks

Try this one :
This will help you for partial fetching of data
SELECT /*+ first_rows(50) no_cpu_costing */
vendor_id
FROM po_vendors
WHERE end_date_active IS NULL
AND enabled_flag = 'Y'
AND vendor_id NOT IN (
SELECT vendor_id
FROM po_headers_all
WHERE TO_DATE (creation_date) BETWEEN TO_DATE (SYSDATE - 365)
AND TO_DATE (SYSDATE))
overall your query is also fine, because, the in this query the subquery always contain less data compare to main query.
