Html form for select * from table a

Hi all,
I m looking for report on header/footer part from one apex pages
which will display context from table a, like sql statement
select * from table a, written in html.
Is any examples in java script/html select from tables
(and same insert into table A (...) select * from table b)
thanks,
Gordan

Hello Gordan,
Do you want to show the whole report or just some data of it?
If it's for ex just the name and address you could create two items and have a process or computation to fill it with your select statement.
If it's the whole report, just create the report and put it in for ex. Region 1. In your page template you can specify that Region 1 needs to come into the footer.
Regards,
Dimitri

Problem in displaying data onto Form after selecting from table.

Hi there,
I keep hitting this error when I tried to display the data after the selection from table. Using backing beans w data control to do it
Err: java.lang.ClassCastException: java.util.Collections$SingletonList cannot be cast to java.lang.Integer
Table used ArrayList to retrieve out the wanted data. E.g uses A object
To display: selected data to retrieve the selected row to display as a read-only form layout below the table. E.g. need to get A.getName() to match with B object B.getName() then uses the B object to retrieve out the data.
Anyone know how to do it?

Hi
use the follwing code
int rowcount = wdContext.node<Name>().size();
while(rs.next())
IPrivate<ViewName>.I<Name>Element tabnode =wdContext.node<Name>().get<Name>ElementAt(i);
tabnode.nodeAuthoriseNode().invalidate();
tabnode.nodeAuthoriseNode().addElement(0,authele);
tabnode.nodeAuthoriseNode().setLeadSelection(0);

Open sys_refcursor for select from table variable?

Hi,
I've got a challenge for you! :-)
I've got a procedure that has a lot of logic to determine what data should be loaded into a table variable. Because of various application constraints, i can not create a global temporary table. Instead, i'd like to create a table variable and populate it with stuff as i go through the procedure.
The end result of the procedure is that i must be able to pass the results back as a sys_refcursor. This is a requirement that is beyond my control as well.
Is there a way to make this sort of procedure work?
Create Or Replace Procedure Xtst
Mu_Cur In Out Sys_Refcursor

I would strongly encourage you not to implement something like this. I realize it's tempting when you are working in strict environments where it can take a serious battle to get structures like temporary tables or SQL Types created, but that's really the proper approach to be taking.

How do I do SELECT * FROM TABLE WHERE KEY IN ({list})?

The title says it all really.
Is there a reasonable performant way to perform the query
SELECT * FROM TABLE WHERE KEY IN ({list})where {list} is String []?
I am currently creating a PreparedStatement with a for loop like this StringBuffer sb = new StringBuffer ("SELECT * FROM TABLE WHERE ID IN (");
for (int ii=0;ii<keys.length;ii++) {
sb.append (keys [ii]);
if (ii != keys.length-1) sb.append (",");
sb.append (")");but this means that the prepared statement is created each time I call my method and so I'm not sure that the optimizer will find it easy to cope with. Is there a construction that I'm missing along the lines of SELECT * FROM TABLE WHERE KEY = ? where I can create the PreparedStatement once and just call setObject or something on it when the values in {list} change?

but this means that the prepared statement is created
each time I call my method and so I'm not sure that
the optimizer will find it easy to cope with.You are right, the optimizer won't find that easy to deal with (presuming that is even relevant for your driver/database.) But most optimizers won't do anything with statements that change and that is what you are doing.
You could create several prepared statements which have a common number of bind variables. For example 10 statements with from 1 to 10 bind values. This will work if most of the queries use those.

Select * from table not working with Oracle OBDC driver

Hello,
In our web development we have been using the MS ODBC for Oracle
driver to connect to our Oracle db. We decided to try the
Oracle ODBC driver because it supports the commandTimeout
property in ASP which the MS driver does not. The problem I'm
running into now is that all of our select * from table
statements appear not to be working. The Oracle ODBC driver
version we are using is ver 8.00.05.00. Is there something that
I'm not doing properly? If I take the same select * from table
statement and name the columns, I dont get any error. Otherwise
I'm getting a Subscript out of range error. It seems strange to
me that this driver would not support a select * from table
statement (which I''m told is the case by another developer
here).
Is there something I'm missing?
Thanks,
Pete

I'm positive I have a connection. Otherwise I wouldn't get a
response when I name the columns instead of using *.
There must be something else that I'm missing or doing wrong.
I've actually been looking into alternative ODBC drivers to see
if I have the same problems but none that I have found support
commandTimeout.
Any other ideas?

Performace Which is better ? : Bapi inside a loop OR Select from Tables

Hi Gurus,
I have a report which displays purchase info records.
If I am selecting from tables i need to use EINA, EINE, EORD and some other tables.
There is a BAPI which gets all purchase info records specific to a vendor , material , purchasing organisation.
QUESTION: Performace wise which is the better Approach, either selecting from tables or BAPI for Purchase info records
Regards
Avi.

Whether it using BAPI or select. you need to check the performance. If you have full key for these tables EINA, EINE, EORD then mak a select outside of the loop and within loop use READ TABLE statement with binary search. of if you want multiple records within loop then use loop insdie loop.
Your final objective is to minimise the database hits . If you use bapi inside loop then your database hits will be more
select from EINA
select from EINE
select from EORD
loop at itab,
read table EINA
read table EINE
read table EORD
endloop

Edit HTML FORM for Travel Request in BADI

Hi Experts,
I'm trying to use the BADI FITP_REQUEST_HTML_FORM_BADIDEF to edit the HTML form for travel request.
I need to add and hide fields in tables, but I don't need to create new tables in the form.
The example is like the following:
CALL METHOD co_dd_document->add_table
    EXPORTING
      no_of_columns = 2
      width         = '350'
      border        = '0'
    IMPORTING
      table         = lo_estc_table.
set estc columns
CALL METHOD lo_estc_table->add_column
    EXPORTING
      width = '150'
    IMPORTING
      column = lo_col1.
MOVE text-t04 TO lv_text.
CALL METHOD lo_col1->add_text
    EXPORTING
      text = lv_text.
We don't need to create new tables, we need to add fields in an existing table of the form.
Somebody knows how can I do that?
I hope you can help me.
Thanks in advance.
Oscar.

Special Grant to use "Select * from Table(cast..."??

Hi,
I've recently created the types and function to use the Table(Cast(funtion) as type)). It works fine, and gives me the correct result. I've granted execute on the types and on the function to a role that is enabled for a user, but when the user tries to use the "select * from table(cast(function) as type))", he gets a "ORA-01031: Insufficient Privileges" error message. Is there any other grant that must be given to the role, so that the user can execute the select?
Thanks in advance!
Daniel

Hi Kamal,
I'm not sure what anonymous PL/SQL block means. When I (or the user) try to run the select, I enter all the information, i.e., the owners for the type and function: "select * from table(cast(a.my_function(my_argument) as a.my_type))". I'm trying to use SQLPlus at this time, and I have Oracle 8i.
I didn't to explicitly grant execute to the user because that would go against some rules I have to follow... I'll se if I give it a try though!
Thanks!

Insert into table a (select * from table b) - need pk?

Hi there.
I'm going to insert into table FINAL (select * from table STAGING) - same structure but in STAGING the ID column has nulls.
Do I need to provide the ID (primary key) for table FINAL or will it get created based on sequence/trigger?
If I were doing this in a loop I'd get the next val from the sequence but on a simple insert, I'm curious.
thanks!

hmm.. what is ?
it didn't like it.

How to achieve that "SELECT * FROM table WHERE age BETWEEN 18 AND 23 AND n"

How to achieve the SQL like that "SELECT * FROM table WHERE age BETWEEN 18 AND 23 AND name = 'Will' " with BDB C-API
The primary key in the primary database is 'age' ,and the secondary key in the secondary index is 'name' ,in a lot of examples ,there are all simple , but how to do that complex one.thx~

Can I simulate SELECT * FROM TABLE WHERE ROW IN (1111,2222) using SQLJ

I have a fct like
public void fct(String inStr) {
String str = "SELECT * FROM TABLE WHERE ROW IN" + inStr;
// then I xecute the query using JDBC connection
But I want to do the same thisn using SQLJ like:
public void fct(String inStr) {
#sql [nctx] iter = { SELECT * FROM TABLE WHERE ROW IN :inStr}
When I run the second version and give a parameter like "(1111,2222)" it gives
ORA-01722: invalid number error.
Is there a way to give parameters to in clauses of SQLJ statements.
Thanks in regard.

This is a SQLJ FAQ. You can find the FAQ at:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html
Your question is addressed in the following section:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#variablesizevaluelist
Note that that section has a typo. The lines:
? // populate mynumbers
#sql { SELECT * FROM tab WHERE col in (:(a[0]),:(a[1]),?};
should read:
... // populate mynumbers
#sql { SELECT * FROM tab WHERE col in (:(a[0]),:(a[1]),...};
By the way, with the next release SQLJ will support pasting in of dynamic SQL fragments. Then you'll be able to do pretty much what you are trying to accomplish here (albeit with slightly different syntax). Until then you'd have to use the workarounds from the FAQ.

Select * from table where rownum 5; no rows returned? why is it so?

select from table where rownum > 5;*
no rows returned. why is it so?
can anyone explain me?

Hi,
rownum is pseudo column, and it is based on the sort order.
For ex, if you want to get the first 5 employees who get the least salary, you use,
select ename,sal from
    (select ename, sal
     from emp
     order by sal )
    where rownum<=5
ENAME      SAL
SMITH      800
ALLEN1     890
JAMES      951
TURNER     998
ADAMS      1100Suppose, if you want to use highest salary, you change the order by and not the rownum. So, it becomes,
select ename,sal from
    (select ename, sal
     from emp
     order by sal desc)
    where rownum<=5
ENAME      SAL
KING1      5000
FORD       3000
SCOTT      3000
JONES      2975
BLAKE      2850 So, its not the rownum you would want to change, but the order by.

Is select from view faster then select from table..???

Hello Gurus,
I want to query some data from two tables, both of table have many columns (attributes) and many rows...
I use several where clauses to retrieve data from those tables..
witch one is faster, I create a view or I just "select" from those tables???
Regards.

Views are simply queries and like queries there are fast and slow ones.I disagree.
First of all, to use a view you are executing a query to get a result set, then accessing the data from that result set - a built-in extra step to perform to get data.First of all that entire explanation of how views work is not correct. The optimizer will rewrite the query to make the view go away if possible.

Second, when accessing the data from the view the result sets don't have indexes for fast lookups and efficient joins on later steps.This is also known as just making stuff up and is not how the database works. care to share any references at all for any of this?
>
Third, the systems I've seen that use views extensively - I am looking at one now - tend to perform joins on views using the same tables with the same data over and over. This is a design issue and not specifically a problem with views but they lend themselves to this misuse much too easilyCorrect as I said a view is just a query, and just like queries there are good fast views and bad slow views

I'll concede that the problem is not specifically with views themselves but as I just said they lend themselves to misuse. Tuning views of views and views joined to views is difficultYes, queries can be misused as can almost all SQL functions and functionality.

Nothing that you have posted that is accurate changes that.

Form for edit pair table

Hi,
my problem is how to create edit form for pair two tables for example COMPANIES and CAMPAIGNS.
create table COMPANIES (
id integer,
name varchar2(100));
create table CAMPAIGNS (
id integer,
name varchar2(100));
create table PAIRS (
id_company integer,
id_campaign integer);
And the problem is which wizard to edit user friendly (it is important) table PAIRS. My idea is to select certain campaign and then filter companies based on filter critera and then by unselecting checkbox be able to delete specified companies.
Thanks
