How to run a View with parameters

Hi guys,
I have a view which has to take the USERNAME of the current user connected to the database as a parameter:
Create or Replace View XYZ(A1,A2,A3)
AS Select AA1, AA2, AA3
from X1, X2
where ...
and X1.id_valid in (select XX3.id_valid
               from X3 XX3
               where XX3.ID_VALID = X1.id_valid
               and XX3.username = USERNAME1 )
Where USERNAME1 is the database user connected to it!.
Could you give me a hand please?

Just use the USER pseudocolumn ...
create view v as
select *
from all_users
where username = user;Richard

How to create a view with parameters; read the documentation but nothing!

Hello!
I'm new to the Oracle world but together with my coworkers we need to very quickly study Oracle to figure out whether we'll add Oracle to our list of supported databases or not.
Question: How do I create a view with parameters?
I've read the documentation but I could not find this! I found the sql syntax to create a view but no parameters whatsoever...
I have found on the web some very complicated way of doing this, but doesn't Oracle support Views with parameters?
The goal here is to return a recordset, don't forget, so,please don't speak about stored procedures unless you are going to tell me how to get a recordset out of a stored procedure! ;)
Thanks for all your help and attention!
Jorge C.

You can set up a parameterized view via context as follows:
1. Set up a procedure to set your context values:
create or replace procedure p_set_context (p_context IN VARCHAR2,p_param_name IN VARCHAR2,p_value IN VARCHAR2)
as
BEGIN
sys.dbms_session.set_context(p_context,p_param_name,p_value);
END;
2. Create your context using the procedure you just created
create or replace context my_ctx using p_set_context
3. This is the test table I'll use
create table my_table(col1 number)
and populate it:
begin
for v_index in 1..10
loop
insert into my_table values(v_index);
end loop;
end;
and the view that will be parameterised
create or replace view v_my_table as select col1 from my_table where col1 between sys_context('my_ctx','start_range') and sys_context('my_ctx','end_range')
4. Now set the parameters using the procedure above.
begin
p_set_context('my_ctx','start_range','1');
p_set_context('my_ctx','end_range','5');
end;
5. Selecting from my_table will give you 1 to 10 (no surprise there :-) )
selectng from v_my_table will give you 1 to 5
You can use the context to set formats etc using the same principle. A common gotcha to watch for is trying to set the context directly using DBMS_SESSION.SET_CONTEXT instead of creating a procedure. This belongs to SYS and SYS won't have the privileges to set your context so you get an insufficient privileges result leading to much headscratching and unnecessary grants (at least that's my understanding of it).
Sorry Jorge, as you're new to Oracle I should also have pointed out for completeness sake, that you can change the parameters at any time through recalling the p_set_context, for example, following on from above, after your "select * from v_my_table" and seeing 1 to 5, you could then do
begin
p_set_context('my_ctx','start_range','3');
end;
and when you requery 'Select * from v_my_table' you will now see rows 3 to 5.
Bit of a simplistic example, but you can see how easy it is. :-)

How to run JavaFX Jar with JRE 7 on MAC OS Lion 10.7.5 ?

I had java 1.6 installed on my MAC OSX Lion 10.7.5. When I am trying to run that JavaFX application jar
java -jar application.jar
It always shows a dialog "The application require a newer version of Java Run-time" with download link. Even I have downloaded and successfully installed it on my MAC machine but it still shows me the same window.
It installed jre-7u10-macosx-x64.dmg but java -version is always point to 1.6.
Then I searched for Java Preferences to point the current JRE 1.7 but I could find Java Preferences at Applications -> Utilities -> Java -> Java Preferences.
I found an Java Icon on System Preference. When I am trying to open that widow it's showing me error -- the java control panel opens in a separate window and nothing happens when we click on Re-open the Java Control Panel.

I would like to know -- how to run JavaFX jar with JRE7 on MAC OS Loin 10.7.5? Is their any other way to run the JavaFX application JAR with JRE7?

To find a copy of LP7 you would need to look for a copy on eBay.. However, the protection method used with LP7 no longer functions so you cannot register it and therefore you cannot use it. unless you have already registered LP7 yourself in the past using the security key dongle provided
Any version of LP7 from a torrent would be an illegal (and most likely non working) version due to the protection that was used at that time... and so posting about it here, was not be wise.
So.. thats why my previous answer was so brief... Simply put, you cannot use LP7 unless you already have a validated and registered security dongle... even if you found a copy of LP7 somewhere
The only practical solution is to find some kind soul who already has a working version of LP7 installed, that you can send the projects to... for them to do the conversion for you.
I would, but I no longer have LP7 installed here on any of my testbed Macs...

Do I need to download the whole JAVA 1.7 on MAC to run the JAR? No
Can not I run the Jar file with Jre7?Yes, you can.
This may be because I have downloaded the JRE 1.7Yep, that's correct, the java_home command only works for jdk's - sorry for the confusion.
For jre7+ versions, only a single Oracle jre version is allowed to be installed on the machine at a time - making a tool like java_home redundant for jre checking.
Weirdly, jre7u10 does not supplant the Apple Java on the command line path by default. If you just type java -v, then the Apple java version will displayed if you have an old Java 6 from Apple and a new Oracle jre7+.
The Oracle jre is always located under (also somewhat strangely):
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaTo test jar launching, I used the willow JavaFX browser pre-release jar available here:
http://code.google.com/p/willow-browser/downloads/detail?name=Willow-0.1-prerelease.jar
Then I launched the jar from the command line using:
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -jar Willow-0.1-prerelease.jar The JavaFX jar ran fine on jre7 with the above machine.
The test machine was running Mac OS X 8 with Oracle jre7u10 installed as well as the Apple Java 6 runtime, but no Oracle jdk7+ installed.

Is it possible to create views with parameters ?

Hi,
As MS-Access, is it possible to create views with parameters ?
Ms-Access syntax : parameters [a] text; select * from table where code = [a]
If yes, can you give samples ?
Regards
Pascal

I suggest you you write a stored procedure that returns a recordset in oracle. Then execute the stored procedure and loop through the record set.
Look in in MS Knowledgebase searching on ADO Stored Proceedures for the VB/C++/VBS .. code.
Look in in Oracle PL/SQL guide for the Stored Proceedure code.

How to run execute immdiate with variables

Hi friends,
How to run execute immdiate with variables in v_stmt below?
I dont know how to declare the value of i here.
Set serveroutput on;
DECLARE
   i        VARCHAR (20);
   v_stmt   VARCHAR2 (100);
   CURSOR c
   IS
      SELECT sqlid FROM temp1;
BEGIN
   OPEN c;
   LOOP
      FETCH c INTO i;
      EXIT WHEN c%NOTFOUND;
      DBMS_OUTPUT.put_line (i);
      v_stmt := 'select * from table(dbms_xplan.display_cursor('&i',null))'
      execute immediate v_stmt;
   END LOOP;
   CLOSE c;
END;
/Regds,
Kunwar.

You first need to use a bind variable (named ':v' in SQL statement in my example):
set serveroutput on;
DECLARE
   i        VARCHAR (20);
   v_stmt   VARCHAR2 (100);
   CURSOR c
   IS
       -- modified for a quick test
      SELECT sql_id FROM v$sql where child_number > 2;
BEGIN
   OPEN c;
   LOOP
      FETCH c INTO i;
      EXIT WHEN c%NOTFOUND;
      DBMS_OUTPUT.put_line (i);
      v_stmt := 'select * from table(dbms_xplan.display_cursor(:v,null))';
      execute immediate v_stmt using i;
   END LOOP;
   CLOSE c;
END;
/However because your SELECT statement returns several rows you need to adapt your code to process all rows returned (as already suggested in first reply to your message).
Instead of using PL/SQL, I recommend to generate a SQL file using only SQL and then to run the generated SQL file.
For example:
spool edx.sql
set serveroutput on
declare
v_stmt varchar2(100);
v_q char(1):='''';
begin
dbms_output.put_line('spool edx.log');
for s in (select sql_id from v$sql where child_number >2)
loop
dbms_output.put_line('select * from table(dbms_xplan.display_cursor(' || v_q || s.sql_id || v_q || ',null));');
end loop;
dbms_output.put_line('exit');
end;
spool ofThis generates a SQL file similar to :
spool edx.log
select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));
select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));

Powershell: how to run vbs script with switches.

Background: To remove a specific service, I usually log into a server, go to path c$\Program files\HP... find a specific vbs, and run it using CMD.exe.
Now, I'm new to powershell, so I'm looking into automating this job. When I use CMD, I run cscript path\serviceinstall.vbs
-r.
How do I add cscript switches to powershell?
IF
((test-path -path "servername\C$\Program Files\...") -eq "true")
invoke-command -scriptblock ""servername\C$\Program Files\...\serviceinstall.vbs -r?

1. You cannot run VBS as a scriptblock.
2. If youactually were to have read the full help ypu would have seen how to use the command.
3. Given you initial questin and the vague answers you gave there is nothing any could do to help you.
If you do not give accurate information you will not likely get answers that are helpful.
I recommend starting at the beginning and learning PowerShell basics. If you had done that you would know that a script block is not a quoted string with vbscript in it or the path to a file.
When working with any technology it is important to read the instructions carefully. It is also useful to knowhow to do basic research on the technology you are trying to learn.
There are 15 examples in PowerShell V2 for Invoke-Command. Here they are as captured directly from PowerShell V2. (The is no update-help on V2. All help is built in.)
-------------------------- EXAMPLE 1 --------------------------
C:\PS>invoke-command -filepath c:\scripts\test.ps1 -computerName Server01
Disks: C:, D:, E:
Status: Warning, Normal, Normal
Description
This command runs the Test.ps1 script on the Server01 computer.
The command uses the FilePath parameter to specify a script that is located on the local computer. The script runs
on the remote computer and the results are returned to the local computer.
-------------------------- EXAMPLE 2 --------------------------
C:\PS>invoke-command -computername server01 -credential domain01\user01 -scriptblock {get-culture}
Description
This command runs a Get-Culture command on the Server01 remote computer.
It uses the ComputerName parameter to specify the computer name and the Credential parameter to run the command in
the security context of "Domain01\User01," a user with permission to run commands. It uses the ScriptBlock paramete
r to specify the command to be run on the remote computer.
In response, Windows PowerShell displays a dialog box that requests the password and an authentication method for t
he User01 account. It then runs the command on the Server01 computer and returns the result.
-------------------------- EXAMPLE 3 --------------------------
C:\PS>$s = new-pssession -computername server02 -credential domain01\user01
C:\PS> invoke-command -session $s -scriptblock {get-culture}
Description
This example runs the same "Get-Culture" command in a session (a persistent connection) on the Server02 remote comp
uter. Typically, you create a session only when you are running a series of commands on the remote computer.
The first command uses the New-PSSession cmdlet to create a session on the Server02 remote computer. Then, it saves
the session in the $s variable.
The second command uses the Invoke-Command cmdlet to run the Get-Culture command on Server02. It uses the Session p
arameter to specify the session saved in the $s variable.
In response, Windows PowerShell runs the command in the session on the Server02 computer.
-------------------------- EXAMPLE 4 --------------------------
C:\PS>invoke-command -computername Server02 -scriptblock {$p = get-process powershell}
C:\PS> invoke-command -computername Server02 -scriptblock {$p.virtualmemorysize}
C:\PS>
C:\PS> $s = new-pssession -computername Server02
C:\PS> invoke-command -session $s -scriptblock {$p = get-process powershell}
C:\PS> invoke-command -session $s -scriptblock {$p.virtualmemorysize}
17930240
Description
This example compares the effects of using ComputerName and Session parameters of Invoke-Command. It shows how to u
se a session to run a series of commands that share the same data.
The first two commands use the ComputerName parameter of Invoke-Command to run commands on the Server02 remote comp
uter. The first command uses the Get-Process command to get the PowerShell process on the remote computer and to sa
ve it in the $p variable. The second command gets the value of the VirtualMemorySize property of the PowerShell pro
cess.
The first command succeeds. But, the second command fails because when you use the ComputerName parameter, Windows
PowerShell creates a connection just to run the command. Then, it closes the connection when the command is complet
e. The $p variable was created in one connection, but it does not exist in the connection created for the second co
mmand.
The problem is solved by creating a session (a persistent connection) on the remote computer and by running both of
the related commands in the same session.
The third command uses the New-PSSession cmdlet to create a session on the Server02 computer. Then it saves the ses
sion in the $s variable. The fourth and fifth commands repeat the series of commands used in the first set, but in
this case, the Invoke-Command command uses the Session parameter to run both of the commands in the same session.
In this case, because both commands run in the same session, the commands succeed, and the $p value remains active
in the $s session for later use.
-------------------------- EXAMPLE 5 --------------------------
C:\PS>$command = { get-eventlog -log "windows powershell" | where {$_.message -like "*certificate*"} }
C:\PS> invoke-command -computername S1, S2 -scriptblock $command
Description
This example shows how to enter a command that is saved in a local variable.
When the entire command is saved in a local variable, you can specify the variable as the value of the ScriptBlock
parameter. You do not have to use the "param" keyword or the ArgumentList variable to submit the value of the local
variable.
The first command saves a Get-Eventlog command in the $command variable. The command is formatted as a script block
The second command uses the Invoke-Command cmdlet to run the command in $command on the S1 and S2 remote computers.
-------------------------- EXAMPLE 6 --------------------------
C:\PS>invoke-command -computername server01, server02, TST-0143, localhost -configurationname MySession.PowerShell
-scriptblock {get-eventlog "windows powershell"}
Description
This example demonstrates how to use the Invoke-Command cmdlet to run a single command on multiple computers.
The command uses the ComputerName parameter to specify the computers. The computer names are presented in a comma-s
eparated list. The list of computers includes the "localhost" value, which represents the local computer.
The command uses the ConfigurationName parameter to specify an alternate session configuration for Windows PowerShe
ll and the ScriptBlock parameter to specify the command.
In this example, the command in the script block gets the events in the Windows PowerShell event log on each remote
computer.
-------------------------- EXAMPLE 7 --------------------------
C:\PS>$version = invoke-command -computername (get-content machines.txt) -scriptblock {(get-host).version}
Description
This command gets the version of the Windows PowerShell host running on 200 remote computers.
Because only one command is run, it is not necessary to create persistent connections (sessions) to each of the com
puters. Instead, the command uses the ComputerName parameter to indicate the computers.
The command uses the Invoke-Command cmdlet to run a Get-Host command. It uses dot notation to get the Version prope
rty of the Windows PowerShell host.
To specify the computers, it uses the Get-Content cmdlet to get the contents of the Machine.txt file, a file of com
puter names.
These commands run synchronously (one at a time). When the commands complete, the output of the commands from all o
f the computers is saved in the $version variable. The output includes the name of the computer from which the data
originated.
-------------------------- EXAMPLE 8 --------------------------
C:\PS>$s = new-pssession -computername Server01, Server02
C:\PS> invoke-command -session $s -scriptblock {get-eventlog system} -AsJob

C:\PS> $results = $j | Receive-Job
Description
These commands run a background job on two remote computers. Because the Invoke-Command command uses the AsJob para
meter, the commands run on the remote computers, but the job actually resides on the local computer and the results
are transmitted to the local computer.
The first command uses the New-PSSession cmdlet to create sessions on the Server01 and Server02 remote computers.
The second command uses the Invoke-Command cmdlet to run a background job in each of the sessions. The command uses
the AsJob parameter to run the command as a background job. This command returns a job object that contains two ch
ild job objects, one for each of the jobs run on the two remote computers.
The third command uses a Get-Job command to save the job object in the $j variable.
The fourth command uses a pipeline operator (|) to send the value of the $j variable to the Format-List cmdlet, whi
ch displays all properties of the job object in a list.
The fifth command gets the results of the jobs. It pipes the job object in $j to the Receive-Job cmdlet and stores
the results in the $results variable.
-------------------------- EXAMPLE 9 --------------------------
C:\PS>$MWFO-LOg = Microsoft-Windows-Forwarding/Operational
C:\PS> invoke-command -computername server01 -scriptblock {param($log, $num) get-eventlog -logname $log -newest $nu
m} -ArgumentList $MWFO-log, 10
Description
This example shows how to include the values of local variables in a command run on a remote computer.
The first command saves the name of the Microsoft-Windows-Forwarding/Operational event log in the $MWFO-Log variabl
e.
The second command uses the Invoke-Command cmdlet to run a Get-EventLog command on the Server01 remote computer tha
t gets the 10 newest events from the Microsoft-Windows-Forwarding/Operational event log on Server01.
This command uses the "param" keyword to create two variables, $log and $num, that are used as placeholders in the
Get-EventLog command. These placeholders have arbitrary names that do not need to match the names of the local vari
ables that supply their values.
The values of the ArgumentList parameter demonstrate the two different ways to specify values in the argument list.
The value of the $log placeholder is the $MFWO-Log variable, which is defined in the first command. The value of t
he $num variable is 10.
Before the command is sent to the remote computer, the variables are replaced with the specified values.
-------------------------- EXAMPLE 10 --------------------------
C:\PS>invoke-command -computername S1, S2 -scriptblock {get-process powershell}
PSComputerName Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName
S1 575 15 45100 40988 200 4.68 1392 powershell
S2 777 14 35100 30988 150 3.68 67 powershell
C:\PS> invoke-command -computername S1, S2 -scriptblock {get-process powershell} -HideComputerName
Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName
575 15 45100 40988 200 4.68 1392 powershell
777 14 35100 30988 150 3.68 67 powershell
Description
This example shows the effect of using the HideComputerName parameter of Invoke-Command.
The first two commands use the Invoke-Command cmdlet to run a Get-Process command for the PowerShell process. The o
utput of the first command includes the PsComputerName property, which contains the name of the computer on which t
he command ran. The output of the second command, which uses the HideComputerName parameter, does not include the P
sComputerName column.
Using the HideComputerName parameter does not change the object. You can still use the Format cmdlets to display th
e PsComputerName property of any of the affected objects.
-------------------------- EXAMPLE 11 --------------------------
C:\PS>invoke-command -comp (get-content servers.txt) -filepath c:\scripts\sample.ps1 -argumentlist Process, Service
Description
This example uses the Invoke-Command cmdlet to run the Sample.ps1 script on all of the computers listed in the Serv
ers.txt file. The command uses the FilePath parameter to specify the script file. This command allows you to run th
e script on the remote computers, even if the script file is not accessible to the remote computers.
When you submit the command, the content of the Sample.ps1 file is copied into a script block and the script block
is run on each of the remote computers. This procedure is equivalent to using the ScriptBlock parameter to submit t
he contents of the script.
-------------------------- EXAMPLE 12 --------------------------
C:\PS>$LiveCred = Get-Credential
C:\PS> Invoke-Command -ConfigurationName Microsoft.Exchange `
-ConnectionUri https://ps.exchangelabs.com/powershell `
-Credential $LiveCred -Authentication Basic `
-scriptblock {Invoke-Command {Set-Mailbox dan -DisplayName "Dan Park"}
Description
This example shows how to run a command on a remote computer that is identified by a URI (Internet address). This p
articular example runs a Set-Mailbox command on a remote Exchange server. The backtick (`) in the command is the Wi
ndows PowerShell continuation character.
The first command uses the Get-Credential cmdlet to store Windows Live ID credentials in the $LiveCred variab the c
redentials dialog box appears, enter Windows Live ID credentials.
The second command uses the Invoke-Command cmdlet to run a Set-Mailbox command. The command uses the ConfigurationN
ame parameter to specify that the command should run in a session that uses the Microsoft.Exchange session configur
ation. The ConnectionURI parameter specifies the URL of the Exchange server endpoint.
The credential parameter specifies tle. Whenhe Windows Live credentials stored in the $LiveCred variable. The Authe
nticationMechanism parameter specifies the use of basic authentication. The ScriptBlock parameter specifies a scrip
t block that contains the command.
-------------------------- EXAMPLE 13 --------------------------
C:\PS>$max = New-PSSessionOption -MaximumRedirection 1
C:\PS> Invoke-Command -ConnectionUri https://ps.exchangelabs.com/powershell `
-scriptblock {Invoke-Command {Get-Mailbox dan} `
-AllowRedirection -SessionOption $max
Description
This command shows how to use the AllowRedirection and SessionOption parameters to manage URI redirection in a remo
te command.
The first command uses the New-PSSessionOption cmdlet to create a PSSessionOpption object that it saves in the $max
variable. The command uses the MaximumRedirection parameter to set the MaximumConnectionRedirectionCount property
of the PSSessionOption object to 1.
The second command uses the Invoke-Command cmdlet to run a Get-Mailbox command on a remote server running Microsoft
Exchange Server. The command uses the AllowRedirection parameter to provide explicit permission to redirect the co
nnection to an alternate endpoint. It also uses the SessionOption parameter to specify the session object in the $m
ax variable.
As a result, if the remote computer specified by the ConnectionURI parameter returns a redirection message, Windows
PowerShell will redirect the connection, but if the new destination returns another redirection message, the redir
ection count value of 1 is exceeded, and Invoke-Command returns a non-terminating error.
-------------------------- EXAMPLE 14 --------------------------
C:\PS>$so = New-PSSessionOption -SkipCACheck
PS C:\> invoke-command $s { get-hotfix } -SessionOption $so -credential server01\user01
Description
This example shows how to create and use a SessionOption parameter.
The first command uses the New-PSSessionOption cmdlet to create a session option. It saves the resulting SessionOpt
ion object in the $so parameter.
The second command uses the Invoke-Command cmdlet to run a Get-Hotfix command remotely. The value of the SessionOpt
ion parameter is the SessionOption object in the $so variable.
-------------------------- EXAMPLE 15 --------------------------
C:\PS>enable-wsmanCredSSP -delegate server02
C:\PS> connect-wsman Server02
C:\PS> set-item wsman:\server02*\service\auth\credSSP -value $true
C:\PS> $s = new-pssession server02
C:\PS> invoke-command -session $s -script {get-item \\Net03\Scripts\LogFiles.ps1} -authentication credssp -credenti
al domain01\admin01
Description
This example shows how to access a network share from within a remote session.
The command requires that CredSSP delegation be enabled in the client settings on the local computer and in the ser
vice settings on the remote computer. To run the commands in this example, you must be a member of the Administrato
rs group on the local computer and the remote computer.
The first command uses the Enable-WSManCredSSP cmdlet to enable CredSSP delegation from the Server01 local computer
to the Server02 remote computer. This configures the CredSSP client setting on the local computer.
The second command uses the Connect-WSman cmdlet to connect to the Server02 computer. This action adds a node for t
he Server02 computer to the WSMan: drive on the local computer, allowing you to view and change the WS-Management s
ettings on the Server02 computer.
The third command uses the Set-Item cmdlet to change the value of the CredSSP item in the Service node of the Serve
r02 computer to True. This action enables CredSSP in the service settings on the remote computer.
The fourth command uses the New-PSSession cmdlet to create a PSSession on the Server02 computer. It saves the PSSes
sion in the $s variable.
The fifth command uses the Invoke-Command cmdlet to run a Get-Item command in the session in $s that gets a script
from the Net03\Scripts network share. The command uses the Credential parameter and it uses the Authentication para
meter with a value of CredSSP.
I suggest spending som etime learning the basics. It will save you a lot of frustration in the future.

Encapsulating a query in a view with "parameters"

I have a complex query using analytic functions and an inline view, something like:
select * from (
select a, b, c, row_number() over (partition by x, order by y) rn
where b like 'XXX%'
where rn = 1;
(The actual query is a little more complex, but that's the idea). This query performs very well.
As the query is of some general use, I'd like to package it up. However, the 'XXX%' pattern will vary with each use.
If I try to make a view v which is the query minus the XXX% where clause, the optimiser cannot merge the where clause and the view in a query like
select * from v where b like 'XXX%'
This doesn't surprise me too much - merging like that is going to be hard (if indeed it's possible at all!) As a result, the query using the view is significantly slower.
Is there any way of making my original query reusable? For PL/SQL, I can use a function returning a REF CURSOR and taking the pattern as a parameter - but I need to use this from SQL.
I could write a pipelined function and then do select * from table(my_fn('XXX%')). However, this is in 8i, where I don't have that option. Also, for a pipelined function, I'd need to define a record type and an associated table type - what seems like quite a lot of code for what is conceptually pretty simple.
Have I missed any obvious options? I can live with the pipelined function and "no way until 9i" - but only as a general answer. For my current specific issue, that's equivalent to "you can't do this".
I thought of using SYS_CONTEXT, but if I understand correctly, I can only use that in PL/SQL, as I can't set the context outside of an authorised package. Is that right, or is there a way I could use contexts? (Hmm, I need to be able to use the query from SQ, but I could probably execute a PL/SQL procedure before running the query, to set things up - does that help?)
Thanks for any suggestions.
Paul.

SYS_CONTEXT would work, as would package global variables.
I once wrote an example about this (though with TABLE function but for your case the principle stays the same) which you may find here:
Re: TABLE FUNCTION - Using database view - send parameters to the function.

View with parameters

Hello,
Can we create the view with the parameters? How to do that? We need to create the sql script with parameter for super user to query, instead of create sql script then we would like to create the view then user can select only view.
Many thanks in advance. :-)

Hi,
Views using SYS_CONTEXT, as Justin mentioned, are perhaps the most common way to simulate parameterized views in Oracle.
Another method is to use a table (usually a Global Temporary Table) to hold the parameters. The view can then join to the table, use it in scalar sub-queries, IN-sub-queries, etc.
This is the best way if you need to use the same parameterized view two (or more) times in the same query, with different parameters each time.
