ADF with JSF: How to execute a Sql statement created in a form

Hello to every body,
I'm working in JDeveloper 11.1.2.1.0, I have to do a development when the user can create a SQL statement and I have execute that before to do commit to the DB(Oracle DB).
Example:
The user create the next query:
"+Select id_boss, boss_name from boss where boss_salary>5000+"
I don't know how to do that with the current persistence and without create a Connection Method.

The video tutorial is excellent but I have a problem because I'm working with Release 2 and when I try to do something like the video I had the next error:
FachadaConsultaLocalImp cannot be cast to ApplicationModule
the code to try to create a ViewObject is the next:
DCDataControl dc = this.getBinding().findDataControl("FachadaConsultaLocal");
String dataProvider=dc.getDataProvider().toString();
ApplicationModule appModule = (ApplicationModule)dc.getDataProvider();
Some idea?

How to execute multiple SQL statements thru frontend?

With SQL Server database, you can execute multiple SQL statements.
Ex.
SQLCommand cmd = new SQLCommand();
cmd.CommandText = "SELECT * FROM EMP; SELECT * FROM DEPT";
cmd.ExecuteXXX();
Note that for SQL Server, ";" (semocolon) is used as a separator.
What separator is required for Oracle ? Or rather, can I execute multiple SQL statements against Oracle database (10g) ?
(Why I want to do it is a totally diff. subject !)
Thanks,
Ami.

Hello,
You could use an anonymous PL/SQL block to batch multiple statements.
If you want to use SELECT statements, you would open a REF CURSOR for each SELECT and return the REF CURSOR to your application. INSERT, UPDATE, and DELETE statements can just be passed as is.
A simple REF CURSOR example might look like:
begin
open :v_refcursor1 for select * from emp;
open :v_refcursor2 for select * from dept;
end;Where v_refcursor1 and v_refcursor2 are parameters defined as a REF CURSOR type.
Hope that helps a bit...

[SOLVED]ADF BC/JSF-how to execute a "ExecuteWithParams" from a b.-bean?

Hello everyone. I am new to ADF BC/JSF web apps. and I have a situation where I have a form that inserts a record into the DB, the page has a backing bean attached to it and the "create" button on the form is attached to a method called "grabarButton_action()" on the backing bean... here I do some validation first and then I commit the changes.... until this moment everything works fine but the thing is that after the insert takes place I need to query and get the new row I just inserted in the DB to get a value from a column that gets inserted using a trigger on the DB.
I have been trying to do this unsuccessfully, I created a ViewObject with bind variables to try to execute the query using the "executeWithParams" action but I dont know exactly how to send the values to the action and get the results from it...
Can anybody point me in the right direction or give me some code examples here please???!!!
Thanks.

DragonV,
Why not just mark the attribute in your EO as "refresh after insert" and/or "refresh after update?" These are there to support attributes that are populated by a trigger.
Hope this helps,

How to execute multiple sql statements in parallel ?

Hi There,
I have 10 stored procedures, each one will take approximately 5 seconds to run individually.
Now I need to combine the results of these 10 stored procedures into single result set.
So I have created one more stored procedure "proc_AllSPs" to get the single result set.
The procedure "proc_AllSPs" is taking one minute to run because all the procedures inside the "proc_AllSPs" are running
one after the other and taking 5 seconds each.
If there is any other way that all the procedures run parallelly, then the procedure "proc_AllSPs" can run in 5 seconds time.
Sorry if I am not being elaborated.
PLease get back to me if any piece of information is needed.
Any kind of help is truly thankful.
Thanks,
SequelBug

Could you tell me how to execute two stored procedures or two sql statements in parallel
For eg:
First procedure name is proc_sp1 which takes 1 minute to run
Second procedure name is proc_sp2 which takes 1 minute to run
I want to accomplish the below query in 1 minute by executing statement1 and statement2 parallelly.
go
select * from openrowswt('sqloledb','server','exec proc_sp1') --statement1
union
select * from openrowset('sqloledb','server','exec proc_sp2') --statement2
go
OR
go
Select * into #Temp1 from openrowswt('sqloledb','server','exec proc_sp1') --statement1
select * into #Temp2 from openrowset('sqloledb','server','exec proc_sp2') --statement2
Select * from #Temp1
UNION ALL
Select * from #Temp2
go

How to execute multiple sql statement?

In an single transaction I want to execute two update statements. I don't know how to break those statements and send to oracle from Asp.Net to execute.
I tried go and ; .
Below is myQuery string*
update abc set One = 10 where Two = 3 ; update xyz set Three = 10 where Four = 3 ;
Additional info
I am using sql comment text in asp.net
I am using executenonquery command in asp.net.

Hi,
If you want to execute multiple statements in a single transaction, you could either:
a) create a local transaction (via an OracleTransaction object), then call executenonquery multiple times within that transaction, or
b) pass them all in an anonymous block for a single round trip.. ie, begin update abc set One = 10 where Two = 3 ; update xyz set Three = 10 where Four = 3 ;end;
The database doesn't permit multiple statements passed at once (other than in a plsql block).
Hope it helps, corrections/comments welcome

PS, questions such as this would be better posted in the ODP.NET forum; this forum is for issues regarding ODT.NET (a VS plugin)

How to execute multiple sql statements in oracle?

I want to execute multiple statements in a single transaction in oracle. Following are my queries:
Create table temp_table as Select * from table;
SELECT * FROM temp_table d;
drop table temp_table ;
I am using sql comment text in asp.net
I am using executenonquery command in asp.net.
Thanks,

SigCle ,
Here's an example that executes 3 statements;
begin insert into foo values(1); insert into foo values(2); insert into foo values(3); end;
923354,
The block doesn't compile because temp_table doesn't exist at the point you're trying to compile the anonymous block. I'd recommend re-reading the doc link and forum link provided to get a better understanding of how temp tables work, as it's simply different with Oracle. You don't create Oracle temporary tables on the fly; you create them ahead of time and then just use them. The data itself is already specific to a particular session; you don't create and drop the table each time.
Also, you can't just "select * from table" in plsql. The results have to GO SOMEWHERE. Usually you'd either open a cursor and process it in the block, or send out a ref cursor if you want to send the data to a client side app. The ref cursor data wouldn't actually be fetched until the block completes though, so you'd need to use ON COMMIT PRESERVE ROWS, which would also mean you'd need to clean up the data yourself (delete the data from the table when you're done with it).
Corrections/comments welcome.

How do I use SQL statements to perform calculations with form fields????

Please help!!! I don't know how to use a SQL statement within my APEX form......
My form is below. The user will enter the values in the form. Click on Submit. Then we need to run a SQL select statement with those values.
Our form looks like this:
Start_Date ____________
Per_Period ____________
Period ____________
[Submit Button]
The user will enter these 3 values in the form.
This is an example of an user providing the values:
Start_Date 03/14/08_______
Per_Period $200.00________
Period 4____________
[Submit Button]
Then they will click the Submit Button.
The SQL statement (BELOW) returns output based on the users selections:
START_DATE PER_PERIOD PERIOD
14-MAR-2008 00:00 200 Week 1 of 4
21-MAR-2008 00:00 200 Week 2 of 4
28-MAR-2008 00:00 200 Week 3 of 4
04-APR-2008 00:00 200 Week 4 of 4
Total 800
This is the full text of the SQL that makes the output above:
with criteria as (select to_date('03/14/08', 'mm/dd/rr') as start_date,
4 as periods,
'Week' as period,
200 per_period from dual),
periods as (select 'Week' period, 7 days, 0 months from dual
union all select 'BiWeek', 14, 0 from dual
union all select 'Month', 0, 1 from dual
union all select 'ByMonth', 0, 2 from dual
union all select 'Quarter', 0, 3 from dual
union all select 'Year', 0 , 12 from dual
t1 as (
select add_months(start_date,months*(level-1))+days*(level-1) start_date,
per_period,
c.period||' '||level||' of '||c.periods period
from criteria c join periods p on c.period = p.period
connect by level <= periods)
select case grouping(start_date)
when 1 then 'Total'
else to_char(start_date)
end start_date,
sum(per_period) per_period,
period
from t1
group by rollup ((start_date, period))
THANKS VERY MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How to execute an SQL query present in a string inside an ABAP program?

hello,
How to execute an SQL query present in a string inside an ABAP program

Raut,
You can execute Native SQl statements.
Ex: To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
In Native SQL statements, the data is transported between the database table and the ABAP program using host variables. These are declared in the ABAP program, and preceded in the Native SQL statement by a colon (:). You can use elementary structures as host variables. Exceptionally, structures in an INTO clause are treated as though all of their fields were listed individually.
If the selection in a Native SQL SELECT statement is a table, you can pass it to ABAP line by line using the PERFORMING addition. The program calls a subroutine <form> for each line read. You can process the data further within the subroutine.
As in Open SQL, after the ENDEXEC statement, SY-DBCNT contains the number of lines processed. In nearly all cases, SY-SUBRC contains the value 0 after the ENDEXEC statement. Cursor operations form an exception: After FETCH, SY-SUBRC is 4 if no more records could be read. This also applies when you read a result set using EXEC SQL PERFORMING.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.

How to execute a .sql file from a batch file

Hi all
I've to take backup of a database weekly twice on every wednesday & Friday @ 5pm IST. I've written a hot backup script, which works every well.
now i want to automate the script. ie i want this script to run on wednesday & friday @ 5pm without any human interfearance ie with out actually any1 executing this script.
i created a batch file prod.bak with the following lines
@echo off
set oracle_sid=testdb
set oracle_home=d:\oracle\ora92
sqlplus /nolog
connect sys as sysdba/oracletest@testdb
this batch file when eexecuted connects me to sql prompt.
Now i want to execute my backup script bkp.sql automatically when it is connected to sql prompt.
(i tried with these lines in the above batch file...
call bkp.sql---it just opens the bkp.sql file in notepad & displays the script
start bkp.sql---same as call
connect / as sysdba/pwd@[email protected] --- does not work simply remains a the sql prompt.
At 17:00 /Every:w,f "d:\bkp.sql"---does not work simply remains at the sql promt.)
Can any1 let me know what should i write in the batch file that will execute the bkp.sql file automatically after it gets connected to sql prompt. M using oracle 9i.
I'll manage he time through windows utility of scheduling task.. Let me know how to execute the .sql file from a batch file.
Thanks
Tripti

Try
sqlplus "sys/oracletest as sysdba" @bpk.sql
Working locally, and having set the ORACLE_SID, you don't need to specify the SqlNet alias (@testdb).
Remember to put an exit at the end of the bpk.sql script.

How can I execute Dynamic SQL statement in Forms?

Hi All,
I have to execute dynamic SQL statement from Forms
Below statement I have to execute
"EXECUTE IMMEDIATE v_stmt INTO v_return;".
Googled for the same got results saying, Better use Database function or procedures to execute these Dynamic Statements but We want to execute in forms only.
Can any one help me..
Thanks,
Madhu

So in short you are trading code obfuscation for maintainability and the ability to share code between tools? If from somewhere else you need a procedure already implemented in database PL/SQL (and now ported to forms) this would mean you'd need to implement it in every other tool. In times where you might want to integrate your forms with $other_technology and putting stuff on the database is the first step to share functionality you just go the opposite way? And all that because someone is afraid that somebody might steal your source code? I am sorry to be blunt, but this is just plain stupid.
Leaving aside that some things like Analytic Functions, Bulk processing or execute immediate are not even available in forms your software consists of how many LOC? How long does it take to bring a new developer up to speed with your source code? Imagine how long that would take for a developer who doesn't have coleagues who know their way around.
And just so you know: I work for a ISV selling a closed-source product as well. We have 200+ customers all over the planet. We are well aware that wrapped packages can be reverse engineered. The premise is: stored procedures can be reused in every tool we have, if it makes sense to put stuff on the database by all means do it. If someone would want to reverse engineer our software I'd wish him good luck as some parts are implemented in such a hilarious complicated way I have troubles understanding them (and quite frankly I refuse to understand certain parts, but that's another story). I do work for almost 10 years for that ISV.
In any case the possible solutions have already been mentioned: you have exec_sql, create_group_from_query and forms_ddl to execute dynamic SQL in forms whereas forms_ddl is a one way street and most certainly not the thing you need or want. Take a look at the documentation for the other 2 things.

Doesn't work. Even though @ is different from start in this case but it just doesn't like the way sql and plsql are mixed. For example:
DECLARE n NUMBER := 0;

DBMS_OUTPUT.put_line('Number of partitioned tables = ' || to_char(n));
if n = 0 then
DBMS_OUTPUT.put_line('createViewsProcs.sql');
@createViewsProcs.sql
else
DBMS_OUTPUT.put_line('createPartitionViewsProcs.sql');
@createPartitionViewsProcs.sql
end of;
END;
SQL> @postimp.sql
